Why can magnesium hydroxide be used as a common flame retardant？
With the continuous improvement of living standards, people have higher and higher requirements for the quality of life, and some polymers have come into our daily life.
However, there is a problem in the use of these polymer materials, that is, flammability, which can easily lead to fire accidents. Therefore, we need to add flame retardants to these materials to prevent fire. General flame retardants include alumina, aluminum hydroxide, zinc oxide, magnesium hydroxide and so on. Magnesium hydroxide is widely used in these commonly used flame retardants.
Why can magnesium hydroxide be added to various polymer materials as a common flame retardant? This is because magnesium hydroxide Flame retardant decomposes and releases bound water during heating to absorb a large amount of latent heat and reduce the surface temperature of the synthetic material filled in the flame.
n addition, it can also suppress smoke. When a fire produces a large amount of smoke to conduct heat, people can not escape from the scene. Magnesium hydroxide Flame retardant can solve this problem well and reduce the risk of smoke asphyxiation. In addition to the characteristics of flame retardant and smoke suppression, magnesium hydroxide is also widely favored by people because of its environmental protection and non-toxicity. Used in rubber, chemical, building materials, plastics, electronics, paint, paint and other industries.
1. Magnesium hydroxide flame retardant has high performance-to-price ratio, and high filling amount can be achieved by adding magnesium hydroxide to the polymer.
2. The thermal decomposition temperature of magnesium hydroxide reaches 340 ℃, which is beneficial to increase the processing temperature of plastics, accelerate the extrusion speed, improve the plasticizing effect, shorten the molding time, have high surface gloss, no surface defects and ensure the super peel strength.
3. Magnesium oxide produced by Magnesium Hydroxide For Fire Retardant Coating after combustion and dehydration is a kind of high strength and high heat-resistant material, which can be used as a fire source and a protective wall for toxic and harmful gases. Magnesium hydroxide and acid have strong neutralization ability and can quickly neutralize the acidic gas produced in the process of plastic combustion.
4. The physical morphology of magnesium hydroxide is granular, which is conducive to uniform distribution, good compatibility with the substrate, and has little effect on the mechanical properties of the product.
