1. The reaction process of isocyanate and polyol

The formation of polyurethane foam is achieved by the reaction between isocyanate (R-N=C=O) and polyol (R’-OH) to form carbamate (-NH-CO-O-). This reaction can be divided into the following steps:

  1. Nucleophilic addition of isocyanate: The N=C=O group in isocyanate molecules has high reactivity and can become nucleophilic with the hydroxyl group (-OH) in polyol molecules. The addition reaction forms a carbamate intermediate.

  2. Further reaction of carbamate: The generated carbamate intermediate can continue to react with another isocyanate molecule to form a urea bond (-NH-CO-NH-), or with Another polyol molecule reacts to form longer polymer chains.

  3. Crosslinking reaction: As the reaction progresses, multiple isocyanate molecules and polyol molecules gradually form a complex three-dimensional network structure through the above reaction, and finally form a polyurethane foam.

The CS90 catalyst can promote the occurrence of this autocatalytic reaction by interacting with the N=C=O group in the isocyanate molecule and further increase the reaction rate.

  3. Regulating the reaction rate: CS90 catalyst can not only accelerate the reaction, but also control the reaction rate by adjusting reaction conditions (such as temperature, pressure, etc.). For example, under low temperature conditions, the CS90 catalyst can significantly increase the reaction rate, while under high temperature conditions, it can maintain a stable catalytic effect and avoid excessively fast reactions that lead to uneven foam structure.

  4. Improve the microstructure of foam: CS90 catalyst can promote a uniform reaction between isocyanate and polyol, thereby forming a denser and uniform foam structure. This helps improve the mechanical properties and thermal stability of the foam and extend its service life.

In addition, the CS90 catalyst can also improve the adhesive properties of the epoxy resin, so that the material can be better combined with other substrates in practical applications, and enhance the reliability of the material.

3.4 Other applications

In addition to the above application scenarios, CS90 tertiary amine catalysts also perform well in other fields. For example, in polyurethane coatings, the CS90 catalyst can significantly increase the drying speed and adhesion of the coating, shorten the construction time, and reduce the amount of solvent use; in polyurethane adhesives, the CS90 catalyst can improve the initial adhesion of the adhesive and Final bonding strength improves the weather resistance and chemical resistance of adhesives; in polyurethane sealants, CS90 catalyst can improve the fluidity, curing speed and weather resistance of the sealant, making the sealant better in complex environments sealing effect.

4. Application skills of CS90 tertiary amine catalyst

In order to give full play to the advantages of CS90 tertiary amine catalysts, it is crucial to rationally select and use the catalyst. Here are some common application tips:

4.1 Control the amount of catalyst

The amount of catalyst is used directly affects the reaction rate and material properties. Excessive catalyst will cause the reaction to be too violent and produce too many by-products, affecting the purity and performance of the material; while insufficient catalyst usage will lead to incomplete reactions and the material performance will not meet expectations. Therefore, it is very important to reasonably control the amount of catalyst. According to literature reports, the recommended amount of CS90 tertiary amine catalyst is 0.1%-0.5% of the total reactant mass. For different application scenarios, appropriate adjustments can be made according to specific reaction conditions and material requirements. For example, in the synthesis of polyurethane foam, the amount of catalyst can be appropriately increased to improve foaming speed and uniformity; while in the synthesis of polyurethane elastomers, the amount of catalyst can be appropriately reduced to avoid excessive crosslinking causing the material to become brittle.

4.2 Optimize reaction conditions

In addition to controlling the amount of catalyst, optimizing reaction conditions is also the key to improving material performance. Studies have shown that factors such as temperature, humidity, stirring speed, etc. will affect the catalytic effect of CS90 tertiary amine catalyst. Come generallyIt is said that the CS90 catalyst can perform a good catalytic effect at room temperature, but in some cases proper heating can further improve the reaction rate and material properties. For example, during the curing process of epoxy resin, appropriate heating can accelerate the curing reaction, improve the degree of curing, and improve the mechanical properties of the material. In addition, a reasonable stirring speed also helps to improve the uniformity of the reaction and the performance of the material. Studies have shown that appropriate stirring speed can promote the mixing of reactants, reduce the formation of bubbles, and improve the density of the material.

4.3 Select the right solvent

The selection of solvents also has an important impact on the catalytic effect of CS90 tertiary amine catalyst. The polarity and solubility of different solvents will affect the solubility and reactivity of the catalyst. Generally speaking, solvents with higher polarity (such as water, alcohols, ketones) can better dissolve CS90 catalysts and improve their reactivity; while non-polar solvents (such as hydrocarbons) may reduce the solubility of the catalyst and Reactive activity. Therefore, when selecting solvents, reasonable selection should be made according to the specific reaction system and material requirements. For example, in the synthesis of polyurethane coatings, solvents with higher polarity (eg, ) can be selected to improve the solubility and reactivity of the catalyst; while in the synthesis of polyurethane sealant, solvents with lower polarity (eg, ) can be selected to improve the solubility and reactivity of the catalyst; while in the synthesis of polyurethane sealant, solvents with lower polarity (eg, ) can be selected to improve the solubility and reactivity of the catalyst; while in the synthesis of polyurethane sealant, solvents with lower polarity (eg, ) can be selected to be selected to A, dia) to improve the fluidity and curing speed of the material.

4.4 Combined with other additives

To further improve the performance of the material, it is possible to consider using the CS90 tertiary amine catalyst in combination with other additives. For example, adding plasticizers can improve the flexibility and processing properties of the material; adding fillers can improve the strength and wear resistance of the material; adding antioxidants can improve the aging resistance of the material. Studies have shown that combining the CS90 tertiary amine catalyst with appropriate amounts of plasticizers, fillers, antioxidants and other additives can significantly improve the overall performance of the material. For example, in the synthesis of polyurethane elastomers, adding an appropriate amount of plasticizer can improve the flexibility and processing properties of the material without affecting its mechanical properties; in the curing process of epoxy resin, adding an appropriate amount of filler can improve the strength of the material and wear resistance, without affecting its curing speed.

In addition, a well-known domestic building materials company used CS90 catalyst in the production of its insulation boards, which significantly improved the density and mechanical properties of the insulation boards and enhanced the market competitiveness of the products. These successful application cases show that CS90 tertiary amine catalysts have broad application prospects and great economic value in actual production.

6. Future development direction

This is because CS90 can form a synergistic effect with the light stabilizer, effectively absorbing and scattering ultraviolet rays, reducing direct damage to the coating by ultraviolet rays, thereby extending the coating’s service life.

4. Improve moisture and heat resistance

Humid and heat environment is one of the important factors for coating aging, especially in tropical and subtropical areas. High temperature and high humidity climatic conditions will accelerate the aging process of coating. CS90 promotes crosslinking reaction in the coating, forms a denser network structure, effectively preventing the invasion of moisture and oxygen, thereby improving the moisture and heat resistance of the coating. Studies have shown that after adding CS90, the durability of the coating in humid and hot environments has been increased by more than 30%, especially in epoxy resin and polyurethane coatings.

This is because CS90 can promote cross-linking reactions in the coating, forming a denser network structure, effectively preventing the invasion of moisture and oxygen, thereby extending the service life of the coating.

5. Delay the coating aging process

Aging of coatings is a complex process involving many aspects such as physics, chemistry and biology. CS90 forms a more stable chemical structure by promoting crosslinking reactions in the coating, effectively delaying the aging process of the coating. Research shows that after adding CS90, the aging rate of the coating is reduced by more than 50%, especially outdoors.The performance was particularly significant in the coatings used.

Coating Type Aging rate (years) Weather resistance score (out of 10 points)
