The basic principles and mechanism of high-efficiency reaction foaming catalyst

The reason why high-efficiency reactive foaming catalysts can become the core driving force for personalized customized products is due to their unique chemical characteristics and precise mechanism of action. Simply put, the main task of this catalyst is to accelerate and control the foaming process of polyurethane foam, so that the foam material can achieve ideal physical and structural characteristics in a short time. To better understand this process, we need to start from the basic principles of chemical reactions.

The core of foaming reaction: the encounter between isocyanate and polyol

The formation of polyurethane foam begins with a chemical reaction between isocyanate (R-N=C=O) and polyol (HO-R-OH). In this process, the catalyst plays a role as a "matchmaker", prompting the two to bind faster, forming carbamate bonds (-NH-COO-), and releasing carbon dioxide gas. It is the production of these gases that gradually expand the liquid mixture and finally solidify into a porous foam material.

However, relying solely on natural reaction speeds is far from meeting the needs of modern industrial production. If the reaction is too slow, the foam may collapse; if the reaction is too fast, it may lead to uneven foam structure or cracking of the surface. therefore,It is particularly important to introduce efficient catalysts. The high-efficiency reactive foaming catalyst significantly increases the reaction rate by reducing the reaction activation energy, while also adjusting the kinetic behavior of the reaction to ensure that the entire foaming process is stable and controllable.

Mechanism of action: Synergistic effects of multiple functions

High-efficiency reactive foaming catalysts are not single compounds, but a composite system containing multiple active ingredients. Depending on the way it works, it can be divided into the following categories:

1. Foaming Catalyst
   It mainly promotes the reaction between water and isocyanate to form carbon dioxide gas. This catalyst determines the density and pore size of the foam, which directly affects the lightweight and breathability of the product.

2. Gel Catalyst
   Responsible for accelerating the crosslinking reaction between polyols and isocyanates to form a stable three-dimensional network structure. This catalyst is essential for improving the mechanical strength and elasticity of the foam.

3. Delayed Catalyst
   In certain special application scenarios, delayed catalysts are used to delay the start time of the reaction, so that operators can spend more time adjusting the formula or completing mold filling.

4. Multifunctional Catalyst
   Combining the above two or more functions can not only promote foaming but also enhance crosslinking, and is suitable for high-performance foam production under complex process conditions.

Example of chemical reaction equation

The following are the chemical reaction equations of several key steps in the polyurethane foaming process:

1. Water reacts with isocyanate to form carbon dioxide gas:
   H₂O + R-N=C=O → R-NH-COOH + CO₂↑

2. Reacting polyols with isocyanate to form carbamate:
   HO-R-OH + R’-N=C=O → HO-R-O(-NH-COO-R’)

3. The urethane is further crosslinked to form a network structure:
   (-NH-COO-R’) + R”-N=C=O → (-NH-COO-R’-NH-COO-)

By rationally selecting and matching different types of catalysts, the speed and proportion of the above reactions can be accurately adjusted, thereby achieving a comprehensive optimization of the properties of foam materials.

Although the practical application of high-efficiency reactive foaming catalysts is quite mature, there are still many unsolved mysteries of its deep-seated mechanism of action. In recent years, with the help of advanced characterization techniques and computational simulation methods, researchers have gradually unveiled the mystery of these catalyst work.

Domestic research trends

The team of the Institute of Chemistry, Chinese Academy of Sciences used synchronous radiation X-ray diffraction technology to observe the dynamic changes of organic amine catalysts during polyurethane foaming for the first time. They found that catalyst molecules preferentially adsorb near isocyanate groups at the beginning of the reaction, forming locally enriched areas, thereby significantly reducing the reaction activation energy. This research result provides an important theoretical basis for subsequent catalyst design.

International Frontier Progress

A research team at the Massachusetts Institute of Technology (MIT) used quantum chemistry calculation methods to analyze the electronic structural characteristics of metal salt catalysts in detail. They proposed a new "two-site synergistic catalysis" model, believing that metal ions can not only directly participate in the reaction, but also indirectly affect the behavior of surrounding molecules by inducing polarization effects. Based on this model, they successfully designed a new titanium-based catalyst with a catalytic efficiency of nearly twice as high as that of traditional products.

New Material Development: Expanding the Application Boundaries of Catalysts

With the advancement of science and technology, traditional catalysts can no longer fully meet the needs of emerging application fields. To this end, researchers have begun to try to develop new catalysts with special functions to deal with more complex challenges.
