Abstract:

With the wide application of polymer materials in human production and life, their fire safety problems have become increasingly prominent, and the development of high-efficiency and environmentally friendly flame-retardant smoke suppressants has become one of the urgent problems to be solved in the current material field. However, the smoke suppressants did not receive enough attention compared to the relatively mature research of flame retardants for a long time. Most of the current researches on smoke suppression of polymers are the investigation of the smoke suppression property of a known flame retardant and thus developing the so-called “bifunctional materials” with both flame retardancy and smoke suppression properties. The insufficient attention on the smoke suppressant materials greatly limits their development. As we have known, the mechanisms of combustion and smoke emission varied on different polymer materials due to the diversity of structure and functional groups within different polymer materials. Therefore, the design of flame retardants and smoke suppressants of different polymers should also be significantly different. Meanwhile, the flame retardancy and smoke suppression performances are hard to be optimized simultaneously with one material. Therefore, we propose to separate the flame retardancy and smoke suppression in two different materials and strengthen the development of single-function smoke suppressants. Optimizing the flame retardants and smoke suppressants based on the chemical nature of the polymers separately and then combining them might be an effective way to improve the flame retardancy and smoke suppression performance of polymer materials in the future.
