摘要
以甲苯 2 ,4 -二异氰酸酯 (TDI)和己二胺为原料 ,采用界面聚合法 ,制备了囊心为环状氯化磷腈、囊壁为聚脲的微胶囊。热重分析 (TG)表明 ,微胶囊的热分解温度比纯环状氯化磷腈大大提高。将微胶囊应用于高密度聚乙烯 (HDPE) ,阻燃效果优于纯环状氯化磷腈 ,且HDPE/环状氯化磷腈微胶囊材料的力学性能 。
A polyurea-chlorocyclophosphazene microcapsule flame retardant was prepared by interfacial polymerization process with 2, 4-toluene diisocyanate (TDI) and hexanediamine as the raw materials. TG tests show that the thermal decomposition temperature of chlorocyclophosphazene in microcapsule obviously rises. The flame retardancy of HDPE/chlorocyclophosphazene in microencapsules is improved to than HDPE/chlorocyclophosphazene. Mechanical properties of HDPE/chlorocyclophosphazene microencapsule turns out to be superior to HDPE/chlorocyclophosphazene.
