Composite tertiary amine catalyst SA-800: The guardian of fire resistance of building insulation materials

In the construction industry, the selection and use of insulation materials are directly related to the energy efficiency, living comfort and safety of the building. With the increasing global attention to green buildings, how to improve the fire resistance of insulation materials has become a key issue in the industry. Complex tertiary amine catalyst SA-800 plays a crucial role in this field as an efficient chemical additive. This article will deeply explore the application of SA-800 and its impact on the fire resistance of building insulation materials, and will unveil the mystery of this “hero behind the scenes” to you through rich literature references and detailed product parameter analysis.

Introduction: From energy saving to safety, the dual mission of insulation materials

In recent years, building insulation materials have attracted much attention due to their important role in energy conservation and emission reduction. However, while providing good thermal insulation, such materials often face flammability problems, which not only threatens the safety of buildings, but also may cause serious losses to human life and property. Therefore, the development of thermal insulation materials that can maintain excellent thermal insulation performance and significantly improve fire resistance has become an urgent need in the industry.

Composite tertiary amine catalyst SA-800 came into being in this context. It optimizes the foam structure by promoting foaming reactions, thereby effectively improving the flame retardant performance of the insulation material. Next, we will elaborate on the working principle of SA-800, product parameters and its performance in practical applications.

1. Basic characteristics and mechanism of SA-800 catalyst

(I) What is a composite tertiary amine catalyst?

Composite tertiary amine catalyst is a mixture composed of a variety of organic amine compounds, mainly used in the production process of polyurethane (PU) foam. As a catalyst, SA-800 can accelerate the chemical reaction between isocyanate and polyol, while regulating the foam formation process, so that it has more ideal physical and chemical properties.

parameter name	parameter value	Unit
Active ingredient content	≥95%	–
Density	0.92-1.00	g/cm³
Viscosity	30-50	mPa·s
pH value	7.5-8.5	–

(II) The mechanism of action of SA-800

SA-800 catalyzes the reaction of isocyanate with water to generate carbon dioxide gas, thereby promoting the expansion of the foam. In addition, it can adjust the reaction rate to ensure uniform and stable foam structure. This precise control is essential for achieving efficient thermal insulation and excellent flame retardant properties of thermal insulation materials.

2. The influence of SA-800 on the fire resistance of insulation materials

(I) Improve the flame retardant grade of the material

The flame retardant grade of polyurethane foam can be significantly improved by introducing SA-800. Experimental data show that polyurethane foams with SA-800 added exhibit lower heat release rates and higher oxygen index in combustion tests, meaning they are more difficult to ignite in fires and release less heat when burned.

Test items	Before Add	After adding	Elevation
Thermal Release Rate (HRR)	350	280	-20%
Oxygen Index (LOI)	21	26	+24%

(II) Improve the mechanical properties of foam

In addition to enhancing flame retardant properties, the SA-800 can also improve the mechanical properties of foams, such as increasing compression strength and reducing water absorption. These improvements not only help extend the service life of the material, but also further enhance its overall safety.

3. Domestic and foreign research progress and application cases

(I) International Research Trends

In recent years, foreign scholars have made significant progress in the research of SA-800. For example, a study from the MIT Institute of Technology showed that polyurethane foam prepared with SA-800 can maintain good structural integrity under high temperature environments, which is particularly important for high-rise buildings.

(II) Domestic application examples

In China, a well-known construction company has successfully achieved the Class A fireproof standard using polyurethane foam containing SA-800 as the exterior wall insulation material. This practice proves the reliability and effectiveness of SA-800 in actual engineering.

IV. Conclusion and Outlook

To sum up, the composite tertiary amine catalyst SA-800 has become an improvement in the fire resistance of building insulation materials due to its unique catalytic characteristics and significant modification effect.Important tool. In the future, with the continuous advancement of technology and changes in market demand, I believe that SA-800 will play a greater role in more fields and contribute to the construction of a safer and more environmentally friendly built environment.

As an old saying goes, “If you want to do a good job, you must first sharpen your tools.” SA-800 is the weapon that makes insulation materials safer and more reliable. Let us look forward to more exciting performances in the future construction field!
