Basic principles and technical characteristics of amine foam retardation catalyst
Delayed-Action Amine Catalysts (DAAC) are a special class of chemical substances that are mainly used to regulate the foaming process of polyurethane foam. The basic principle is to achieve precise control of foam density, hardness, resilience and other physical properties by delaying or slowing the reaction rate between isocyanate and polyol. The core function of DAAC is its ability to function within a specific time window, ensuring that the foam maintains ideal fluidity during molding while avoiding premature curing or excessive expansion.
1. Mechanism of action of catalyst
Amine foam delay catalysts mainly regulate foaming reactions through the following mechanisms:
-
Delay effect: DAAC can inhibit the reaction between isocyanate and polyol at the beginning of the reaction and prolong the induction period of the reaction. This allows the foam to have longer flow time in the mold, thereby better filling the molds of complex shapes and reducing bubble defects and surface defects.
-
Acceleration effect: When the reaction reaches a certain temperature or time point, DAAC will quickly release the active ingredients, promoting the rapid progress of the foaming reaction. This “delay-acceleration” mechanism helps improve the uniformity and density of foam materials and improves its mechanical properties.
-
Selective Catalysis: Some DAACs have selective catalytic effects and can preferentially promote a certain type of reaction pathway under certain conditions. For example, some catalysts may preferentially promote the formation of hard segments, thereby enhancing the rigidity and heat resistance of the foam material; while others may promote the formation of soft segments, giving the foam material better flexibility and resilience.
2. Technical Features
Amine foam delay catalysts have the following significant technical characteristics:
-
Strong adjustability: By adjusting the type, dosage and addition of DAAC, the speed and time of foaming reaction can be flexibly controlled. This is particularly important for personalized customization of home products, because the performance requirements of foam materials vary from product design and use scenarios.
-
Wide adaptability: DAAC is suitable for a variety of types of polyurethane foam systems, including rigid foam, soft foam, semi-rigid foam, etc. In addition, it can also work in concert with other additives (such as foaming agents, crosslinking agents, stabilizers, etc.) to further optimize the comprehensive performance of foam materials.
-
Environmentally friendly: Many new amine foam delay catalysts use low-volatile organic compounds (VOC) formulations to meet increasingly stringent environmental standards. This not only helps reduce environmental pollution during the production process, but also improves the health and safety of the products.
-
Cost-effective: Although DAAC is relatively expensive, due to its efficient catalytic performance and wide applicability, the overall production cost can be reduced to a certain extent. In addition, using DAAC can reduce waste rate and improve production efficiency, thus bringing higher economic benefits.
