Combining with the requirements of flame retardant textiles, developing flame retardant products with excellent flame retardant performance and strengthening the supervision and management of fire safety can fundamentally prevent the fire threat of textiles and provide safety assurance for people's lives and properties.

Because of the urgent demand for flame retardant function of textiles, many countries have formulated corresponding flame retardant standards and test methods for textiles. Some countries also enforce the flame retardant performance standards of textiles in combination with relevant laws. In this context, the industry and research departments of various countries competed for flame retardant research of textiles, and formed fierce competition in the international market, thus promoting the development of flame retardant finishing. At present, flame retardant finishing has become an important part of textile science, and it is also a prominent topic in the post finishing of printing and dyeing. With the development of new materials, chemical technology and textile technology, the flame-retardant technology of fabrics will be improved gradually, and become the loyal "guard" of human life and property.

In addition, ATH particle size micronization can also effectively improve the oxygen index, tensile strength, tensile stress and other properties of SBR. Aluminum hydroxide flame retardant has the advantages of non-toxic, good stability, no toxic gas at high temperature, and can reduce the amount of smoke when plastic is burned. Moreover, the temperature of dehydration and heat absorption is relatively low, about 235-350 ℃. Therefore, the flame retardant effect of aluminum hydroxide flame retardant at the beginning of plastic combustion is significant. At the same time, the product price is low and the source is wide.

Therefore, in recent years, it has developed rapidly in the domestic and foreign flame retardant market. The global consumption of flame retardants is nearly 1.4 million tons, 85% of which are additive flame retardants and 15% are reactive flame retardants. In the next five years, it will continue to grow at an average annual rate of 5%, When the content of aluminum hydroxide is 40%, the decomposition temperature of PE (polyethylene), PP (polypropylene), PVC (polychloroethylene) and ABS (acrylonitrile / butadiene / styrene copolymer) can be significantly reduced, which has a good effect of flame retardant and smoke reduction. The flame-retardant polyolefin with 60% aluminum hydroxide can be used as building materials, interior decoration materials for automobiles and ships.

Magnesium hydroxide is a common chemical raw material, widely used as flame retardant, but also used in the manufacture of magnesium salt, refined sugar, pharmaceutical industry, daily chemical industry, etc. Among them, active magnesium hydroxide is an excellent flame retardant with three functions of flame retardant, smoke suppression and filling in rubber and plastic industry. Active magnesium hydroxide has excellent buffering performance, reaction activity, adsorption capacity and thermal decomposition performance. It can be used not only as chemical materials and intermediates, but also as a green environmental flame retardant and additive. In the field of environmental protection, it is mainly used as flame retardant, acid wastewater treatment agent, heavy metal remover, flue gas desulfurizer, etc.
