Improve the quality of flame retardants and ensure safe work

Flame retardant is an additive that can make the polymer difficult to ignite, and the fire makes it burn slowly. According to the classification of elements contained in flame retardants, they can be divided into organic and inorganic flame retardants. Organic flame retardants can be divided into flame retardants, halogen flame retardants (including chlorine and bromine) and nitrogen flame retardants; Inorganic flame retardants include antimony compounds, phosphorus and phosphoric acid, boron compounds, aluminum magnesium hydroxide, zirconium compounds and bismuth compounds. With the development of science and technology and the improvement of people's awareness of environmental protection, the research and application of flame retardants in the world are moving towards non halogenation.

Flame retardant

As a representative of the application of inorganic flame retardance of aluminum hydroxide and magnesium hydroxide, it forms the flame retardance effect on polymers by chemically decomposing the mass fraction of oxygen in the dilution air of endothermic and hot water. It is formed after the decomposition of the insulating layer on the surface of magnesium oxide. It has the chemical stability of non-toxic, smoke and decomposition product inhibition (alumina, magnesium oxide) series, so it does not cause secondary damage.

Flame retardants are chemicals, so we must pay attention to their safety in production, storage, use and other links, otherwise it may cause some major accidents. This aspect is also valued by the government, enterprises and consumers. In view of this situation, we must have a comprehensive understanding of the flame retardants used, and do the safety work in each link in a correct way to prevent problems.

① Conduct a comprehensive toxicity assessment of flame retardants suspected to be harmful to human health and the environment, and strictly control their production, use and use. Once it is confirmed that they are not suitable for use, stop production and sales. For example, tri (dibromopropyl) phosphate was once a widely used and very effective flame retardant. Later, it was found that it was carcinogenic and had been banned in many countries. Pentabromodiphenyl ether and octabromodiphenyl ether, flame retardants that have been evaluated and confirmed to be toxic, have also been banned recently.

② For the newly developed flame-retardant products, we have conducted a more comprehensive research and evaluation on their impact on human health, safety and the environment. We can provide more detailed information on the above aspects to ensure the safety of production and use.

③ What we need to do now is to improve the quality of flame retardants and ensure safety while developing new flame retardants with high safety and strong practicability. Gradually popularize and apply on a large scale. Moreover, it is reasonable to believe that the development of new flame retardants will ensure the use of flame retardant materials, which can not only reduce the fire hazard, but also minimize their impact on the environment.
