摘要/Abstract

摘要： 以磷酸、三聚氰胺、尿素为原料制备阻燃抑烟剂聚磷酰氰胺脲，然后将其应用于TDE-85#环氧树脂中，以顺丁烯二酸酐为固化剂制备了阻燃抑烟环氧树脂。研究了阻燃抑烟剂聚磷酰氰胺脲的吸湿性，纯环氧树脂和阻燃抑烟环氧树脂的极限氧指数、UL-94阻燃性、隔热性能、烧蚀速率和透光率等。研究结果表明，聚磷酰氰胺脲对环氧树脂具有非常优异的阻燃、抑烟功效。

Abstract: A flame retarding and smoke suppressing agent polyphosphoric cyanamine urea was prepared with phosphoric acid, melamine and urea as the raw materials. Then flame retarding and smoke suppressing epoxy was made by adding homemade flame retarding and smoke suppressing agent polyphosphoric cyanamine urea and curing agent maleic anhydride to epoxy resin. The water absorbing capacity of polyphosphoric cyanamine urea and the limited oxygen index (LOI), UL-94 V flame retardancy, thermal insulating properties, ablation velocity as well as light transmittance of flame retarding and smoke suppressing epoxy resin and pure epoxy resin were studied. The results showed that the epoxy resin with polyphosphoric cyanamine urea had better flame retardancy and smoke suppression than pure epoxy resin.
