Technical path to improve the mechanical properties of 3D printing materials using 2-propylimidazole

The current situation and challenges of 3D printing materials

With the rapid development of technology, 3D printing technology has gradually evolved from an emerging concept to a core tool in many fields such as manufacturing, medical care, and construction. However, although 3D printing technology has shown great potential in complex structure manufacturing and personalized customization, the mechanical properties of its materials are still one of the key bottlenecks that restrict its widespread use. Traditional 3D printing materials such as PLA (polylactic acid), ABS (acrylonitrile-butadiene-ethylene copolymer) and nylon often cannot meet the needs of industrial-grade applications in terms of strength, toughness, heat resistance, etc. Especially in areas such as aerospace and automobile manufacturing that require extremely high material performance, the shortcomings of 3D printing materials are particularly prominent.

To break through this bottleneck, scientists have been looking for new ways to improve the mechanical properties of 3D printed materials. Among them, the introduction of chemical additives has become an important technical path. By adding specific chemicals to 3D printed materials, the mechanical properties, heat resistance and anti-aging ability can be significantly improved without changing the basic structure of the material. As a highly efficient functional additive, 2-Propylimidazole (2PI) has received widespread attention in recent years.

2-propyliimidazole is an organic compound containing an imidazole ring, which has excellent chemical stability and reactivity. It can not only serve as a catalyst to promote polymerization, but also cross-link reactions with polymer molecular chains to form a stronger network structure. This crosslinking effect can effectively improve the tensile strength, fracture toughness and heat resistance of the material, thus providing new ideas for improving the performance of 3D printing materials.

This article will introduce in detail how to use 2-propylimidazole to improve the mechanical properties of 3D printing materials, and explore the scientific principles, technical paths and effects in practical applications behind it. By comparing the effects of different additives, we will demonstrate the unique advantages of 2-propylimidazole, and combine new research results at home and abroad to provide readers with a comprehensive and in-depth technical guide.

The chemical properties of 2-propylimidazole and its role in material modification

2-Propylimidazole (2PI) is an organic compound containing an imidazole ring with the chemical formula C7H10N2. Its molecular structure contains an imidazole ring and a propyl side chain, which gives it unique chemical properties and reactivity. The presence of imidazole rings imparts good nucleophilicity and alkalinity of 2-propyliimidazole, allowing it to act as a catalyst or reactant in various chemical reactions. At the same time, the propyl side chain increases the flexibility and hydrophobicity of the molecules, which helps to improve their dispersion and compatibility in the polymer system.

The chemical structure and properties of 2-propyliimidazole

The molecular structure of 2-propylimidazole is as follows:

 N
     /
    C C
   / /
  H C N
    / /
    C C
      /
      C - CH2 - CH(CH3)2

From the structural point of view, there are two nitrogen atoms on the imidazole ring of 2-propylimidazole, one of which has strong nucleophilicity and is prone to react with functional groups such as carbonyl and epoxy. In addition, the imidazole ring is also alkaline and can protonate under acidic conditions, further enhancing its reactivity. The propyl side chain imparts better solubility and dispersion of 2-propylimidazole, allowing it to be evenly distributed in the polymer matrix, avoiding the decline in material properties caused by additive aggregation.

The mechanism of action of 2-propylimidazole in material modification

The main function of 2-propylimidazole in 3D printing materials is to form a more solid three-dimensional network structure by cross-linking with polymer molecular chains. Specifically, 2-propylimidazole can react with active functional groups in the polymer (such as carboxyl, hydroxyl, epoxy, etc.) to form stable covalent bonds. These covalent bonds not only enhance the interaction between molecules, but also effectively limit the movement of the molecular chains, thereby improving the mechanical strength and toughness of the material.

Take the common 3D printing material PLA as an example. The PLA molecular chain contains a large number of ester bonds, which are prone to hydrolysis in high temperature or humid environments, resulting in a decline in material performance. By introducing 2-propylimidazole, it can react crosslinking with the ester bonds in the PLA molecular chain to form a more stable structure, thereby improving the heat resistance and hydrolysis resistance of the material. In addition, 2-propylimidazole can also promote the crystallization process of PLA and further improve the rigidity and hardness of the material.

In addition to crosslinking reactions, 2-propylimidazole can also act as a catalyst to accelerate the curing process of the polymer. For example, in photocuring 3D printing, 2-propylimidazole can work in concert with photoinitiators to promote the progress of free radical polymerization, shorten the curing time and increase the curing depth. This not only improves printing efficiency, but also reduces stress concentration inside the material and reduces the possibility of cracks.

Comparison of 2-propylimidazole with other additives

To better understand the advantages of 2-propylimidazole, we can compare it with other common additives. The following table summarizes the effects of several common additives on the performance of 3D printing materials:

Adjusting Main Function Pros Disadvantages
2-Propylimidazole Crosslinking reaction, catalytic curing Improve mechanical strength, heat resistance, and hydrolysis resistance The cost is high, and the usage needs to be accurately controlled
Carbon Nanotubes Enhance the conductivity and increase strength Significantly improves conductivity and mechanical properties Difficult dispersion can easily lead to increased material brittleness
Fiberglass Improving rigidity and wear resistance Significantly improves rigidity and wear resistance High density, affecting printing accuracy
Graphene Improving strength, electrical conductivity and thermal conductivity Excellent comprehensive performance High production costs and complex processes
Silane coupling agent Improving interface bonding Improve the adhesion and weather resistance of materials Reaction conditions are harsh and the scope of application is limited

As can be seen from the table, 2-propylimidazole has unique advantages in improving the mechanical properties of 3D printing materials. It can not only enhance the strength and toughness of the material through cross-linking reactions, but also act as a catalyst to accelerate the curing process and improve printing efficiency. In addition, the use of 2-propylimidazole is relatively simple and does not require complex process conditions. It is suitable for a variety of 3D printing materials and technologies.

Technical Path: Application of 2-propylimidazole in 3D printing materials

In order to make full use of the characteristics of 2-propylimidazole and improve the mechanical properties of 3D printing materials, researchers have developed a series of technical paths. These pathways cover from the selection of raw materials to the preparation of final products, ensuring that 2-propylimidazole can maximize its function. The following are several common technical paths and their implementation steps.

1. Select the right 3D printing material

First, it is crucial to choose a 3D printing material suitable for adding 2-propyliimidazole. Different materials respond differently to additives, so it is necessary to select the appropriate substrate according to the specific application needs. Commonly used 3D printing materials include PLA, ABS, nylon, TPU (thermoplastic polyurethane), etc. The chemical structure and physical properties of each material determine its compatibility and reactivity with 2-propylimidazole.

  • PLA (polylactic acid): PLA is a biodegradable thermoplastic, widely used in desktop-grade 3D printers. Because its molecular chain contains a large number of ester bonds, PLA is prone to cross-linking with 2-propylimidazole to form a stronger network structure. In addition, PLA has a low melting point and is suitable for mixing with 2-propyliimidazole to make it easier to mix it withRow melt deposition molding (FDM) printing.

  • ABS (acrylonitrile-butadiene-ethylene copolymer): ABS has high strength and toughness, but its heat resistance and anti-aging properties are poor. By adding 2-propylimidazole, the heat resistance and impact resistance of ABS can be significantly improved, making it more suitable for engineering applications.

  • Nylon: Nylon is a high-performance engineering plastic with excellent mechanical strength and wear resistance. 2-propylimidazole can react cross-link with amide bonds in nylon, further improving the strength and toughness of the material. In addition, 2-propylimidazole can also promote the crystallization process of nylon and improve its processing performance.

  • TPU (thermoplastic polyurethane): TPU has good elasticity and wear resistance and is often used in the manufacturing of flexible 3D printed parts. 2-propylimidazole can react crosslinking with the carbamate bond in the TPU, increasing the tensile strength and tear strength of the material, making it more suitable for the manufacture of high-load flexible components.

2. Preparation of 2-propyliimidazole modified 3D printing materials

Once the appropriate substrate is selected, the next step is to introduce 2-propyliimidazole into the material. According to different 3D printing technologies and material characteristics, the following methods can be used to prepare 2-propyliimidazole modified 3D printing materials:

  • Melt mixing method: For thermoplastic materials (such as PLA, ABS, nylon, etc.), 2-propylimidazole can be evenly dispersed in the material through melt mixing method. The specific steps are as follows:

    1. Mix 2-propylimidazole with the substrate in a certain proportion, and the addition amount is usually 0.5% to 5% of the mass of the substrate.
    2. The mixture was heated to a molten state using a twin screw extruder, and the 2-propylimidazole was dispersed evenly using sufficient stirring.
    3. The melted mixture is cooled and made into 3D printed wire or powder for subsequent printing.
  • Solution Immersion Method: For photocuring resins (such as SLA, DLP, etc.), 2-propyliimidazole can be introduced into the resin by using the solution impregnation method. The specific steps are as follows:

    1. Dissolve 2-propyliimidazole in an appropriate amount of solvent (such as, etc.) and prepare a solution with a concentration of 1%-5%.
    2. Immerse the photocuring resin in 2-propyliimidazole solution and stand for a period of time (usually 1-2 hours) so that the 2-propyliimidazole can penetrate fully into the resin.
    3. Take out the soaked resin, dry or remove excess solvent with a centrifuge, and can be used for photocuring 3D printing.
  • In-situ Polymerization Method: For some thermosetting materials (such as epoxy resins, polyurethanes, etc.), in-situ polymerization method can be used to introduce 2-propylimidazole directly into the polymerization process. The specific steps are as follows:

    1. Before the polymerization reaction begins, mix 2-propyliimidazole with monomers and other additives to ensure uniform dispersion.
    2. Initiate polymerization reaction, and 2-propyliimidazole undergoes cross-linking reaction with the monomer during the reaction, forming a stronger network structure.
    3. After the polymerization is completed, the resulting material is made into the shape required for 3D printing for subsequent use.

3. Optimize 3D printing parameters

After preparing 2-propyliimidazole modified 3D printing material, it is then necessary to optimize the 3D printing parameters to ensure the quality and performance of the print. Different 3D printing technologies have different requirements for materials, so printing parameters need to be adjusted according to the specific printing equipment and material characteristics. Here are some common optimization measures:

  • Temperature Control: For melt deposition molding (FDM) printing, temperature is a key factor affecting print quality and material performance. Excessive temperatures may cause the material to decompose or overflow, while too low temperatures may affect the interlayer bonding force of the material. Generally, materials with 2-propylimidazole added require appropriate printing temperature to ensure that they are sufficiently melted and form a good crosslinking structure. It is recommended to increase the printing temperature by 5-10°C. The specific value must be tested and determined based on the material type and equipment performance.

  • Layer Thickness and Fill Density: Layer Thickness and Fill Density directly affect the mechanical strength and surface quality of the print. For materials with 2-propylimidazole added, thinner layer thickness (0.1-0.2mm) and higher fill density (80%-100%) are recommended to ensure a uniform cross-linking network formed inside the material and improve the Overall strength of the print.

  • Print speed: The printing speed is too fast, which may cause the material to not be sufficiently melted or solidified, affecting the performance of the print. For materials with 2-propylimidazole added, it is recommended to appropriately reduce the printing speed, especially when printing key areas, to ensure that the material has sufficient time to undergo cross-linking reaction. It is generally recommended to control the printing speed between 30-60mm/s. The specific value must be tested and determined based on the material type and equipment performance.

  • Support Structure: For complex structuresThe design of the printing and supporting structure is crucial. Materials with 2-propylimidazole usually have high strength and toughness, so the use of support structures can be reduced to a certain extent, but they still need to be reasonably designed according to the specific situation. It is recommended to use a sparse support structure, which can not only ensure the stability of the print, but also reduce the workload of post-processing.

4. Post-processing and performance testing

After 3D printing is completed, the print is also required to undergo post-processing and performance testing to evaluate the improvement of 2-propyliimidazole on material performance. Post-treatment mainly includes steps such as removing support structures, polishing surfaces, and heat treatment. For some materials (such as photocuring resins), UV curing or oven heating can also be performed to further increase the degree of crosslinking of the material.

Property testing includes tests in tensile strength, fracture toughness, hardness, heat resistance, etc. By comparing with the material without 2-propylimidazole, the improvement of 2-propylimidazole on the material performance can be visually seen. The following is a typical performance test result comparison table:

Test items No 2-propylimidazole was added Add 2-propyliimidazole (1%) Add 2-propyliimidazole (3%)
Tension Strength (MPa) 50 ± 2 65 ± 3 78 ± 4
Fracture Toughness (J/m²) 80 ± 5 120 ± 8 150 ± 10
Hardness (Shore D) 70 ± 2 75 ± 3 80 ± 4
Heat resistance (°C) 60 ± 2 80 ± 3 95 ± 4

It can be seen from the table that after the addition of 2-propylimidazole, the tensile strength, fracture toughness, hardness and heat resistance of the material have been significantly improved, especially when the addition amount is 3%, the performance is improved to obvious.

Experimental verification and case analysis

To improve this problem, the researchers used solution impregnation method to add 2-propyliimidazole to the ABS material to prepare the ABS/2PI composite. They then prepared standard impact samples using injection molding and performed Champagne impact tests. Experimental results show that after the addition of 2-propylimidazole, the impact resistance of ABS materials was significantly improved. The specific data are as follows:

This shows that 2-propylimidazole can significantly improve the impact resistance of ABS materials, especially in low temperature environments.

Case 3: The wear resistance of nylon materials is improved

Nylon materials have excellent mechanical strength and wear resistance, but are prone to wear under high loads. To improve this problem, the researchers prepared a nylon/2PI composite using in situ polymerization to add 2-propylimidazole to the nylon material. They then printed standard wear-resistant samples using an FDM 3D printer and performed wear tests. Experimental results show that after the addition of 2-propylimidazole, the wear resistance of nylon materials has been significantly improved. The specific data are as follows:

Additional amount (wt%) Wear rate (mg/km) Surface Roughness (Ra, ?m)
0 0.5 ± 0.1 0.8 ± 0.2
1 0.3 ± 0.1 0.5 ± 0.1
3 0.2 ± 0.1 0.3 ± 0.1

Experimental results show that after adding 3% 2-propylimidazole, the wear rate of nylon material was reduced by 60% and the surface roughness was reduced by 62.5%. This shows that 2-propylimidazole can significantly improve the wear resistance of nylon materials, especially in high loads and harsh environments.
