含磷聚硅氧烷阻燃涂层的制备及性能研究
Preparation and performance study of phosphorus-containing polysiloxane flame-retardant coating
摘要
Abstract
In this study,diphenyl phosphite(DP)and vinyltriethoxysilane(VTEO)are employed to craft a phosphorus-containing polysiloxane flame retardant coating,and further imposed to cotton fabric by the sol-gel method.The treated not only substrate maintains its original appearance and color,but also exhibits self-extinguishing behavior with a low damage length(76 mm)after ignition as well as a high limiting oxygen in-dex(27.0%).The mechanism research reveals the flame-retardant role in both the condensed phase and the gas phase.On the one hand,the coating promotes the dehydration and carbonization of substrate and further forms a dense,stable cross-linked char layer.Additionally,it also reduces the release of combustible gases dur-ing the burning processes.Thus,the fire safety performance of substrates is achieved in practical use.关键词
