摘　　要：本文通过甲醛与无卤素膨胀阻燃剂进行反应,该无卤素阻燃剂有机的碳源通过捏合器包裹在基体酸源上,制备得到具有交联结构的无卤素膨胀阻燃剂。测试结果表明,具有交联结构的无卤素膨胀阻燃剂比普通无卤素膨胀阻燃剂初始热分解温度高10-20℃,水溶性为其1/2,使用具有交联结构的无卤素膨胀阻燃剂制得的复合材料(0.75mm)阻燃性能为V0,通过水煮后的阻燃测试,具有良好的耐加工性能、耐析出性能,综合性能明显优于普通无卤素膨胀阻燃剂。In this paper,a halogen-free intumescent flame retardant with cross-linked structure was prepared by reacting formaldehyde with a halogen-free intumescent flame retardant.The organic carbon source of the halogen-free flame retardant was wrapped on the matrix acid source through a kneader.The test results show that the initial thermal decomposition temperature of halogen-free intumescent flame retardants with crosslinked structures is 10-20 ℃ higher than that of ordinary halogen-free intumescent flame retardants,and the water solubility is 1/2 of that.The composite material(0.75 mm) made from halogen-free intumescent flame retardants with crosslinked structures has a flame retardance of V0.After boiling in water,it has good processability and precipitation resistance,The comprehensive performance is significantly superior to ordinary halogen free intumescent flame retardants.
