The Development Of Flame Retardant Technology Is Accompanied By The Development Of Synthetic Polymer Materials.

< p > polymer materials are classified into natural, semi synthetic and synthetic polymers according to their sources. In 1907, Baekeland and his assistant invented the phenolic resin, marking the beginning of the application of synthetic polymer materials. Because of its excellent performance and low investment in production and application, synthetic polymer materials have been developing rapidly in a few decades. Electronic or electrical products, high-rise buildings, aircraft, automobiles, transportation, decoration and decoration industries have used natural or synthetic polymer materials, making polymer materials one of the three most important materials that are parallel to metal and ceramics. < /p >
< p > < < a href= > http:// > www.sjfzxm.com/news/index_c.asp > polymer > /a > has the characteristics of high molecular weight and high carbon content, which makes most polymer materials have strong flammability, flammability and combustion toxicity. This has also become an important reason for the loss of fire when it occurs, thus promoting the development of flame retardant technology. < /p >
The technology of < p > flame retardants has been developed since 1908. G.A.En-gelard and other natural rubber and chlorine have made the flame retardant chlorinated rubber. It has pioneered the development of chemical fire retardant polymers, especially the demand for the rapid development of polymer industry in recent 40 years. The flame retardant technology has developed rapidly, and many efficient and new flame retardants have been developed. < /p >
< p > > a href= "http://? Www.sjfzxm.com/news/index_c.asp" > flame retardant < /a > is used to improve the fire resistance of materials, that is, to prevent materials from being ignited and to inhibit the propagation of flame. According to the relationship between flame retardants and flame retardant substrates, flame retardants can be divided into two categories: additive type and reactive type. According to the types of flame retardants, flame retardants are often divided into halogen system, organic phosphorus system, halogen phosphorus system, nitrogen system, phosphorus magnesium system, inorganic phosphorus nitrogen system, antimony system, aluminum magnesium, inorganic phosphorus system, boron system, aluminum system and so on. < /p >
< p > flame retardants, through the principle of endothermic effect, covering effect, inhibiting chain reaction and asphyxiating effect of non combustible gas in < a href= "http:// www.sjfzxm.com/news/index_c.asp" > < /a > >, make inflammable polymer materials non combustible, non inflammable and self extinguishing, or its flame propagation speed slows down, heat release and smoke emission rate decrease, thus effectively improving fire safety in polymer materials application. < /p >
< p > with the continuous development of science and technology and the popularization and application of polymer materials, the research of flame retardant technology has been further promoted. The scope of its application has covered synthetic polymers such as wood, fabric and other natural polymers, fibers, plastics, rubber, and semi synthetic polymers such as asphalt. < /p >
