Flame Retardant Towards Halogen-free Environmental Protection
flame retardantWidely used in industrial products and daily necessities, brominated flame retardants are one of the world's largest production of flame retardants, but brominated flame retardants can release a lot of pungent odors and corrosive gases when used. The environment is under great threat. In recent years, it has been gradually banned and halogen-free.flame retardantGradually more up.
One: flame retardant, reduce toxicity, smoke suppression phase merger capacity
1.Natural polymer materials and organic synthetic polymer materials, the vast majority are flammable and combustible. Flame retardants are used to prevent these materials from being ignited and to inhibit the spread of flame additives, containing flame retardant materials are more difficult to ignite, and can inhibit the spread of flame, thus preventing the occurrence of fire.
2.Flame retardants should minimize the amount of toxic and corrosive gases and smoke generated during thermal decomposition and combustion of materials, which are often the first and most dangerous factors in fires.
3.阻燃剂的安全性评估包含阻燃剂本身的急性毒性、致癌性、致变异性和刺激性,还应包含燃烧时产生的有毒气体和烟雾量。
Two: flame retardants are divided into three types: additive type, reactive type and post-finishing type.
1.Addition type is physically dispersed in the matrix, mostly used for thermoplastic polymers.
2.Application is as a polymer monomer, participate in the copolymerization reaction, and finally become a monomer in the molecular structure of the polymer, mostly used in thermosetting polymers.
3.The finishing type is flame retardant finishing on fibers or fabrics.
