Due to the main chain of SiOSi and the connection of special structure of organic groups on the silicon atoms, silicone resin is not only a kind of materials with high and low temperature resistance, aging resistance and oxidation resistance, but also a kind of halogenfree and environmental friendly flame retardant materials. Silicon resin as a flame retardant material not only can improve the thermal stability and flame retardant performance of polymer materials, but also does not affect the processing and mechanical properties of polymer materials. Silicon resin does not produce toxic gas such as hydrogen halide during the combustion process. Therefore, as an efficient halogenfree and environmental friendly flame retardant material, silicon resin has increasingly attracted the attention of researchers. This article reported the development of silicone resin flame retardants in recent years at home and abroad, and emphatically introduced the influence of silicone resin as flame retardant additives and flame retardant coatings on flame resistance performance and flame retardant mechanism of polymer materials.
