Magnesium oxide is a key material for improving the flame retardant properties of foam rubber

In construction and industry, fire safety is of paramount importance. Magnesium oxide is an efficient flame retardant, and its application in foam rubber is of great significance for improving the fire resistance of the material.

1. Fire retardant properties of magnesium oxide: Magnesium oxide (MgO) occupies a place among fire retardant materials due to its high melting point and thermal stability. Under high temperature conditions, magnesium oxide can absorb heat and release water vapor, effectively reducing the surface temperature of the material and slowing down the spread of fire. At the same time, its decomposition products help reduce flammable gases and further inhibit combustion.

2. The role of magnesium oxide in foam rubber: As an inorganic filler, magnesium oxide can significantly improve its flame retardant properties when combined with materials such as polyurethane foam. Research shows that the synergistic effect of magnesium oxide and other flame retardants can greatly enhance the fire protection properties of polyurethane materials.

3. The importance of surface modification technology: In order to improve the compatibility between magnesium oxide and polymer materials, surface modification technology has become particularly important. The modified magnesium oxide can be better dispersed in the foam rubber and improve the overall performance of the material. Infrared spectrum and SEM image analysis show that there is chemical adsorption between the surface modifier and magnesium oxide, and the agglomeration phenomenon of the modified magnesium oxide is improved.

4. Application of morphology control technology: The morphology of magnesium oxide has a direct impact on its performance. By precisely controlling the synthesis conditions, magnesium oxide with specific morphologies, such as flakes and whiskers, can be prepared. These special morphologies of magnesium oxide can not only improve the flame retardant properties of foam rubber, but also enhance its mechanical properties.

5. Production process of magnesium oxide foamed fireproof board: The production of magnesium oxide foamed fireproof board involves mixing magnesium oxide with flame retardants, stabilizers, etc., adding foaming agent, stirring and then pouring into the template for solidification. This method produces fire-resistant panels with excellent thermal and physical properties.

The application of magnesium oxide in flame-retardant and fire-proof foam rubber not only improves the fire-proof performance of the material, but also further enhances its application potential in the field of fire-proof materials through surface modification and morphology control technology. With the continuous advancement of technology, the application prospects of magnesium oxide in fireproof materials will be broader, providing more protection for construction and industrial safety.
