摘　　要：聚烯烃是一类价格低廉、力学性能优异、化学稳定性优良的热塑性塑料,应用市场广泛。但其极易燃且产生大量熔滴,严重制约了其在电线电缆等需要高度消防安全领域的应用。为了提高聚烯烃材料的阻燃性能,人们开发了多种阻燃剂和技术。其中,有机硅是一种高效、防熔滴、低烟、环境友好型的阻燃剂,被认为是极有前途的阻燃剂,文中综述了近年来有机硅在聚烯烃中的研究方向和进展,并展望了其应用前景。Polyolefin,a kind of thermoplastic with low price,excellent mechanical properties and chemical stability,was widely used in market.However,as extremely flammable substance with the production of a large number of droplets,the application of polyolefin in fields requiring high fire safety,such as wire and cabled,was restricted.To improve the flame-retardant performance of polyolefin,various flame retardants and technologies have been developed.Among them,silicone flame retardant,with high-efficiency,anti-droplet,low-smoke and environment-friendly properties,was considered to be a promising flame retardant.Therefore,the research progress of silicone flame retardant in polyolefins in recent years was reviewed in this paper,and the application prospect was also forecasted.
