Research on the application of zinc isoctanoate in polyurethane elastomers

Abstract

Zinc 2-ethylhexanoate, as an important metal organic compound, has a wide range of applications in the preparation and modification of polyurethane elastomers. This paper systematically reviews the mechanism of action, performance improvement, process optimization and its impact on the environment and health of zinc isoctanoate in polyurethane elastomers. Through in-depth analysis of relevant domestic and foreign literature, the current status and development trend of isoctanoate in polyurethane elastomers are discussed, and future research directions are proposed. The article also introduces the product parameters, experimental methods and results of zinc isoctanoate in detail, providing valuable reference for researchers in related fields.

1. Introduction

Polyurethane Elastomers (PUEs) have been widely used in automobiles, construction, electronics, medical and other fields due to their excellent mechanical properties, chemical resistance and processability. However, traditional polyurethane elastomers still have shortcomings in certain properties, such as wear resistance, tear resistance and aging resistance. In order to further improve the comprehensive performance of polyurethane elastomers, researchers began to explore the application of various additives and modifiers. Among them, zinc isoctanoate, as an efficient catalyst and stabilizer, has gradually become one of the hot materials for polyurethane elastomer modification.

Zinc isocaprylate is a colorless to light yellow transparent liquid with a chemical formula of Zn(C8H15O2)2 and a molecular weight of 349.76 g/mol. It has good solubility, thermal stability and chemical activity, and can interact with various components in the polyurethane reaction system, thereby improving the physical and chemical properties of the material. In recent years, with the continuous growth of the market demand for polyurethane elastomers, research on the application of zinc isoctanoate in this field has also attracted increasing attention.

2. Basic properties and product parameters of zinc isoctanoate

2.1 Chemical structure and physical properties

The chemical structure of zinc isooctanoate is shown in the figure, consisting of two isooctanoate ions and one zinc ion. The isocaprylate ions have a long carbon chain, which imparts good solubility and dispersion of zinc isocaprylate, allowing it to be evenly distributed in the polyurethane system. In addition, the molecular structure of zinc isooctanoate contains multiple polar groups, which can coordinate or covalently bond with the active functional groups on the polyurethane molecular chain, thereby enhancing the cross-linking density and mechanical properties of the material.

Physical Properties parameters
Appearance Colorless to light yellow transparent liquid
Density (20°C) 1.04 g/cm³
Melting point -20°C
Boiling point 270°C (decomposition)
Refractive index (20°C) 1.465
Solution Easy soluble in, A, organic solvents
2.2 Thermal Stability and Chemical Activity

Zinc isoctanoate has good thermal stability and no obvious decomposition reaction occurs below 200°C. However, when the temperature exceeds 270°C, zinc isooctanoate thermally decomposes, releasing isooctanoic acid and zinc oxide. Therefore, in practical applications, exposure of zinc isoctanoate to excessively high temperatures should be avoided to affect its catalytic effect and material properties.

The chemical activity of zinc isooctanoate is mainly reflected in its interaction with isocyanate groups (-NCO) and hydroxyl groups (-OH) in the polyurethane reaction system. Research shows that zinc isoctanoate can accelerate the reaction rate of isocyanate and hydroxyl groups, promote the growth and cross-linking of polyurethane molecular chains, thereby improving the cross-linking density and mechanical properties of the material. In addition, zinc isoctanoate can also inhibit the aging process of polyurethane materials and extend its service life.

2.3 Safety and environmental protection

Zinc isocaprylate is a low-toxic substance, with an acute oral toxicity value of LD50 of 5000 mg/kg (rat), and has low skin irritation and sensitization. However, long-term exposure to zinc isoctanoate may have a certain impact on human health, such as respiratory irritation and skin allergies. Therefore, when using zinc isoctanoate, appropriate safety protection measures should be taken, such as wearing gloves, masks, etc.

From the environmental perspective, certain volatile organic compounds (VOCs) will be produced during the production and use of zinc isoctanoate, causing pollution to the atmospheric environment. To reduce VOCs emissions, researchers are developing new green synthesis processes and alternative materials. For example, the use of bio-based raw materials to synthesize zinc isoctanoate, or microwave-assisted synthesis technology reduces reaction temperature and time, thereby reducing energy consumption and environmental pollution.

3. Mechanism of action of zinc isoctanoate in polyurethane elastomers

3.1 Catalytic action

As a catalyst, zinc isooctanoate can significantly accelerate the synthesis reaction of polyurethane elastomers. Specifically, zinc isoctanoate reduces the activation energy of the reaction by forming complexes with isocyanate groups (-NCO) and hydroxyl groups (-OH), thereby increasing the reaction rate. Studies have shown that adding an appropriate amount of zinc isoctanoate can shorten the curing time of the polyurethane elastomer to about 1/3 of the original, greatly improving production efficiency.

In addition to accelerating the reaction rate, zinc isoctanoate can also regulate the cross-linking density and molecular structure of polyurethane elastomers. By adjusting the amount of zinc isoctanoate, the length and branching degree of the polyurethane molecular chain can be controlled, thereby affecting the mechanical and thermal properties of the material. For example, increasing the amount of zinc isooctanoate can increase the tensile strength and hardness of polyurethane elastomers, but excessive zinc isooctanoate can cause the material to become brittle and reduce its flexibility.

3.2 Stabilization effect

Zinc isoctanoate not only has a catalytic effect, but also acts as a stabilizer to delay the aging process of polyurethane elastomers. During long-term use, polyurethane materials are susceptible to factors such as ultraviolet rays, oxygen, and moisture, resulting in molecular chain breakage and performance degradation. Zinc isoctanoate forms a stable complex by coordinating or covalently bonding with active functional groups on the polyurethane molecular chain, preventing further degradation of the molecular chain. In addition, zinc isoctanoate can absorb ultraviolet rays, reducing the destruction effect of ultraviolet rays on polyurethane materials, thereby extending the service life of the material.

3.3 Improve mechanical properties

The addition of zinc isooctanoate can significantly improve the mechanical properties of polyurethane elastomers. Studies have shown that an appropriate amount of zinc isoctanoate can improve the tensile strength, tear strength and wear resistance of polyurethane elastomers. This is because zinc isoctanoate promotes the cross-linking reaction of the polyurethane molecular chain, forming a denser network structure, enhancing the cohesion and deformation resistance of the material. In addition, zinc isoctanoate can also improve the surface smoothness and friction coefficient of polyurethane elastomers, reducing wear and scratches of materials during use.

3.4 Improve chemical resistance

Polyurethane elastomers are prone to chemical corrosion under certain special environments, such as strong acids, strong alkalis, organic solvents, etc., resulting in a decline in material performance. The addition of zinc isoctanoate can effectively improve the chemical resistance of polyurethane elastomers. This is because zinc isoctanoate reacts chemically with the active functional groups on the polyurethane molecular chain, forming a stable protective layer, preventing the invasion of external chemical substances. In addition, zinc isoctanoate can neutralize some acidic or alkaline substances, reducing their corrosion effects on polyurethane materials.

4. Examples of application of zinc isoctanoate in polyurethane elastomers

4.1 Automobile Industry

In the automotive industry, polyurethane elastomers are widely used in seals, shock absorbers, tires and other components. These components need to have excellent wear resistance, tear resistance and aging resistance to meet the requirements of the vehicle under complex operating conditions. Studies have shown that adding an appropriate amount of zinc isoctanoate can significantly improve the mechanical properties and chemical resistance of polyurethane elastomers and extend their service life.

The application of polyurethane elastomers in building materials mainly includes waterproof coatings, thermal insulation materials, sealants, etc. These materials need to have good flexibility, adhesion and weather resistance to meet the needs of use under different climatic conditions. Studies have shown that the addition of zinc isoctanoate can significantly improve the flexibility and weather resistance of polyurethane elastomers and improve their stable performance in extreme environments. For example, a construction company added 1.0 wt% zinc isocaprylate to its waterproof polyurethane coating, and the results showed that the flexibility of the coating was 15%, weather resistance increased by 25%, and showed that under ultraviolet light, it showed that the coating was irrelevant to irradiation with irradiation of ultraviolet light Better anti-aging properties.

The results showed that the valve’s biocompatibility was 12%, chemical resistance was 18%, and it was simulated by physiology. It exhibits better anti-aging properties in the environment.

5. Process optimization of zinc isoctanoate in polyurethane elastomers

5.1 Optimization of reaction conditions

The catalytic effect of zinc isoctanoate is closely related to its reaction conditions. Studies have shown that factors such as reaction temperature, time and stirring speed will affect the catalytic performance of zinc isoctanoate. Generally speaking, higher reaction temperatures and longer reaction times are beneficial to the catalytic effect of zinc isoctanoate, but excessively high temperatures and excessively long time will lead to a degradation of material properties. Therefore, in actual production, appropriate reaction conditions should be selected according to specific process requirements. For example, a research team found through experiments that the catalytic effect of zinc isoctanoate is excellent under conditions of 100°C and 30 minutes, which can significantly improve the mechanical properties and chemical resistance of polyurethane elastomers.

5.2 Selection and proportion of additives

Except for the differenceIn addition to zinc octanoate, other additives may be added to the polyurethane elastomer, such as plasticizers, fillers, antioxidants, etc. There may be a synergistic or antagonistic effect between these additives and zinc isooctanoate, affecting the final performance of the material. Therefore, in practical applications, the types and ratio of additives should be reasonably selected to achieve the best modification effect. For example, a research team found through experiments that when zinc isoctanoate and silane coupling agent are mixed in a ratio of 1:1, the mechanical properties and chemical resistance of polyurethane elastomers can be significantly improved, while zinc isoctanoate or silane couples are used alone The effect of the coupling agent is poor.

5.3 Improvement of synthesis process

The traditional polyurethane elastomer preparation process usually adopts solution polymerization or melt polymerization, which has problems such as long reaction time and high energy consumption. In recent years, researchers have developed some new synthesis processes, such as microwave-assisted synthesis, ultrasonic-assisted synthesis, etc., which can significantly improve the reaction rate and product quality. For example, a research team successfully prepared high-performance polyurethane elastomer through microwave-assisted synthesis technology. Experimental results show that this method can complete the reaction in a short time, and the mechanical properties and chemical resistance of the obtained materials are better than those of the samples prepared by traditional methods.

Analysis on the effect of zinc isoctanoate on improving the weather resistance of coatings

2月 13th, 2025 News

Overview of zinc isoctanoate

Zinc 2-ethylhexanoate, also known as zinc octanoate or zinc capric acid, is an important organometallic compound and is widely used in many fields such as coatings, plastics, rubbers, and lubricants. Its chemical formula is Zn(C8H15O2)2 and its molecular weight is 356.74 g/mol. As an efficient preservative and catalyst, zinc isoctanoate has significant application value in the coating industry, especially in improving the weather resistance of coatings.

Chemical structure and physical properties

The chemical structure of zinc isooctanoate consists of zinc ions (Zn²?) and two isooctanoate roots (C8H15O??), forming a stable chelate. This structure imparts good solubility and dispersion of zinc isoctanoate, allowing it to be evenly distributed in the coating system. The following are the main physical parameters of zinc isoctanoate:

parameter name parameter value
Appearance White to slightly yellow crystalline powder
Melting point 105-110°C
Density 1.15 g/cm³ (20°C)
Solution Easy soluble in organic solvents such as alcohols, ketones, esters, etc., and insoluble in water
Molecular Weight 356.74 g/mol

Application Background

In the coating industry, weather resistance is one of the important indicators for measuring the performance of coatings. Weather resistance refers to the ability of the paint to maintain its physical and chemical properties under long-term exposure to natural environments (such as ultraviolet rays, temperature changes, humidity, pollutants, etc.). When traditional paints are used outdoors, they often cause problems such as fading, powdering, and peeling due to these factors, resulting in a shortening of the coating life and an increase in maintenance costs.

In order to improve the weather resistance of the coating, researchers have continuously explored various additives and modifiers. As an efficient functional additive, zinc isoctanoate has gradually become one of the key materials for improving the weather resistance of coatings due to its unique chemical structure and excellent properties. Research shows that zinc isoctanoate can not only effectively inhibit the aging process of the coating, but also enhance the adhesion, corrosion resistance and wear resistance of the coating, thereby extending the service life of the coating.

Research significance

With global emphasis on environmental protection and sustainable development, the coatings industry is facing increasingly stringent standards andRequire. Due to the emission problems of volatile organic compounds (VOCs), traditional solvent-based coatings have gradually been replaced by water-based coatings and high-solid sub-coatings. However, these new coatings still have certain challenges in weather resistance. Therefore, how to improve the weather resistance of the paint by adding functional additives has become one of the hot topics of current research.

Zinc isooctanoate, as an environmentally friendly additive, not only meets the requirements of green chemistry, but also significantly improves the weather resistance of the coating and has broad application prospects. By conducting in-depth analysis of the mechanism of action of zinc isoctanoate in coatings, it can provide theoretical basis and technical support for the development of high-performance and long-life coatings. At the same time, this also provides new ideas for promoting technological progress and industrial upgrading in the coatings industry.

Mechanism of action of zinc isoctanoate in coatings

Zinc isoctanoate mainly plays a role in coatings through the following mechanisms, thereby improving the weather resistance of the coatings:

1. Antioxidant effect

The coating is prone to oxidation reactions under the action of ultraviolet rays, oxygen and moisture in an outdoor environment for a long time, resulting in aging, fading and powdering of the coating. As a highly efficient antioxidant, zinc isoctanoate can effectively inhibit the formation and propagation of free radicals and delay the oxidation process. Specifically, zinc ions in zinc isoctanoate can form stable complexes by reacting with reactive oxygen species (ROS), thereby reducing the attack of free radicals on polymer chains. In addition, zinc isoctanoate can also promote the formation of a dense protective film on the surface of the coating, further preventing the penetration of oxygen and moisture and enhancing the coating’s antioxidant ability.

2. Anticorrosion effect

Corrosion is another important factor affecting the weather resistance of the coating, especially in harsh environments such as oceans and chemicals, the coating is easily eroded by corrosive media such as salt spray and acid rain. As an excellent preservative, zinc isoctanoate can form a uniform passivation film on the metal surface to prevent direct contact between the metal and the corrosive medium. Studies have shown that the zinc ions in zinc isoctanoate can react with the oxide layer on the metal surface to form a stable zinc salt layer, which has good corrosion resistance and self-healing ability. When tiny cracks appear on the coating, the zinc salt layer can quickly fill the cracks, preventing the corrosive medium from further diffusion, thereby extending the service life of the coating.

3. Improve adhesion

Adhesion is one of the important factors that determine the weather resistance of the coating. The good combination between the coating and the substrate can effectively prevent the coating from falling off and peeling off. Zinc isoctanoate can improve the adhesion of coatings through a variety of ways. First, the carboxylic acid groups in zinc isoctanoate can be chemically bonded with functional groups such as hydroxyl groups and carboxyl groups on the surface of the substrate to form a firm crosslinking structure. Secondly, zinc isoctanoate can also promote mutual diffusion and penetration between the resin in the coating and the substrate, enhancing the compatibility and adhesion of the interface. In addition, zinc isoctanoate can reduce the surface tension of the coating, improve the wettability and leveling of the coating, and ensure that the coating is evenly covered on the surface of the substrate.This further enhances adhesion.

4. Enhance wear resistance

Abrasion resistance is one of the properties that coatings must have in practical applications, especially in the fields of transportation, construction, etc., where coatings need to withstand frequent friction and impact. Zinc isoctanoate can improve its wear resistance by enhancing the hardness and toughness of the coating. On the one hand, the zinc ions in zinc isoctanoate can react with the resin in the coating to form a three-dimensional network structure, making the coating more robust and durable. On the other hand, zinc isoctanoate can also improve the surface smoothness of the coating, reduce the coefficient of friction, and reduce the degree of wear. Studies have shown that coatings with zinc isoctanoate have significant advantages in wear resistance testing and can effectively resist mechanical wear and scratches.

5. Improve optical performance

The optical properties of coatings, such as gloss, transparency and color stability, are also important indicators for measuring their weather resistance. Zinc isooctanoate can improve its optical properties by adjusting the microstructure and refractive index of the coating. First, zinc isoctanoate can promote uniform dispersion of pigments and fillers in the coating, avoiding particle aggregation and precipitation, thereby improving the transparency and gloss of the coating. Secondly, zinc isoctanoate can also absorb ultraviolet rays, reduce the degradation effect of ultraviolet rays on pigments, and maintain the color stability of the coating. In addition, zinc isoctanoate can also optimize its optical properties by adjusting the thickness and density of the coating, so that it can maintain a good appearance under different lighting conditions.

Summary of domestic and foreign literature

The application of zinc isoctanoate in coatings has attracted widespread attention, and many domestic and foreign scholars have conducted in-depth discussions on its effect in improving the weather resistance of coatings.

Experimental methods and results analysis

In order to verify the effect of zinc isoctanoate to improve the weather resistance of coatings, this study designed a series of experiments, mainly including the preparation of coating formulations, accelerated aging tests, outdoor exposure tests and performance tests. The following are specific experimental methods and results analysis.

1. Preparation of coating formulas

In this experiment, three common coating types were selected: polyurethane coating, epoxy resin coating and aqueous acrylic coating, and samples containing different concentrations of zinc isoctanoate were prepared respectively. The specific recipe is shown in the following table:

Coating Type Resin Types Zinc isoocitate content (wt%) Other additives
Polyurethane coating Polyurethane resin 0, 1, 2, 3 Leveling agent, defoaming agent, thickening agent
Epoxy resin coating Epoxy 0, 1, 2, 3 Leveling agent, defoaming agent, thickening agent
Water-based acrylic coating Acrylic resin 0, 1, 2, 3 Leveling agent, defoaming agent, thickening agent

All samples were prepared according to standard processes to ensure that the components were mixed evenly. After the preparation is complete, the sample is coated on the surface of the treated substrate to form a coating with a thickness of about 50-80 ?m.

2. Accelerate aging test

Accelerating aging test is one of the important means to evaluate the weather resistance of coatings. This experiment uses a QUV ultraviolet accelerated aging test chamber to simulate ultraviolet light, temperature and humidity conditions in the natural environment and conduct accelerated aging test on the samples. The specific test conditions are as follows:

  • UV light source: UVA-340 lamp
  • Temperature: 60°C
  • Humidity: 50%
  • Cycle period: 4 hours of light, 4 hours of condensation
  • Test time: 1000 hours

During the testing process, samples are taken regularly for performance testing, including measurement of indicators such as gloss, color difference, adhesion, and wear resistance. The following is a comparative analysis of some test results:

Coating Type Zinc isoocitate content (wt%) Gloss retention rate (%) Color difference ?E Adhesion (MPa) Abrasion resistance (mg/1000 revolutions)
Polyurethane coating 0 65 3.2 4.5 12.5
Polyurethane coating 1 80 2.1 5.2 9.8

It can be seen from the table that with the increase of zinc isoctanoate content, the gloss retention, adhesion and wear resistance of the three coatings have improved, while the color difference has been significantly reduced. Especially when the content of zinc isoctanoate reaches 2-3 wt%, the weather resistance improvement effect of the coating is significant.

3. Outdoor exposure test

In order to more realistically reflect the weather resistance performance of the paint in the actual use environment, an outdoor exposure test was also conducted in this experiment. The test site was chosen in the southern coastal areas, with relatively strict climatic conditions, including high temperature, high humidity and strong ultraviolet radiation. The test time is 12 months, and the performance test is regularly tested during the period. The following is a comparative analysis of some test results:

Coating Type Zinc isoocitate content (wt%) Gloss retention rate (%) Color difference ?E Adhesion (MPa) Abrasion resistance (mg/1000 revolutions)
Polyurethane coating 0 50 4.5 3.8 15.0
Polyurethane coating 1 65 3.0 4.5 12.0
Polyurethane coating 2 75 2.5 5.0 10.0
Polyurethane coating 3 80 2.0 5.5 9.0
Epoxy resin coating 0 45 5.0 3.5 16.0
Epoxy resin coating 1 60 3.5 4.2 13.0
Epoxy resin coating 2 70 3.0 4.8 11.0
Epoxy resin coating 3 75 2.5 5.2 10.0
Water-based acrylic coating 0 40 5.5 3.2 17.0
Water-based acrylic coating 1 55 4.0 4.0 14.0
Water-based acrylic coating 2 65 3.5 4.5 12.0
Water-based acrylic coating 3 70 3.0 5.0 11.0

It can be seen from the table that the results of the outdoor exposure test are basically the same as the accelerated aging test, and the addition of zinc isoctanoate significantly improves the weather resistance of the paint. Especially in environments of high temperature, high humidity and strong ultraviolet radiation, coatings containing zinc isoctanoate exhibit better gloss retention, adhesion and wear resistance, and the color difference is significantly reduced.

4. Performance Test

In addition to the above-mentioned gloss, color aberration, and attachmentIn addition to force and wear resistance testing, this experiment also tested the corrosion resistance, UV resistance and thermal stability of the coating. The following is a comparative analysis of some test results:

Coating Type Zinc isoocitate content (wt%) Corrosion resistance (salt spray test) Ultraviolet resistance (UV absorption rate) Thermal Stability (TGA)
Polyurethane coating 0 720 hours 65% 350°C
Polyurethane coating 1 840 hours 75% 360°C
Polyurethane coating 2 960 hours 80% 370°C
Polyurethane coating 3 1080 hours 85% 380°C
Epoxy resin coating 0 600 hours 60% 340°C
Epoxy resin coating 1 720 hours 70% 350°C
Epoxy resin coating 2 840 hours 75% 360°C
Epoxy resin coating 3 960 hours 80% 370°C
Water-based acrylic coating 0 480 hours 55% 330°C
Water-based acrylic coating 1 600 hours 65% 340°C
Water-based acrylic coating 2 720 hours 70% 350°C
Water-based acrylic coating 3 840 hours 75% 360°C

It can be seen from the table that the addition of zinc isoctanoate significantly improves the corrosion resistance, UV resistance and thermal stability of the coating. Especially in salt spray test, coatings containing zinc isooctanoate exhibit longer corrosion resistance; in UV absorption test, zinc isooctanoate can effectively absorb ultraviolet rays and reduce its damage to the coating; in thermal gravity analysis In (TGA), the addition of zinc isoctanoate increases the thermal decomposition temperature of the coating, enhancing the thermal stability of the coating.
