非卤阻燃聚乙烯的研究

Study on Non-halogenated Flame-retardant System for Polyethylene

本文报道了有机硅复合阻燃聚乙烯的研究工作,试验结果表明:有机硅复合阻燃剂对聚乙烯具有很强的阻燃作用,通过实验,找到了能满足于缓燃和阻燃要求的最佳配方。同时,对该阻燃体系的冒烟,熔融滴落现象及力学、电学性能做了系统的研究讨论,并且探讨了有机硅阻燃体系的阻燃机理。

In this paper, a flame-retardant system for polyethylene (PE) compounded with silicone-based composite containing no halogen has been reported. The results showed that the silicone-based flame-retardant system took a good role in PE. The optimum ingredients and formulations for the system were found. Furthermore, the dripping, smoking, tensile strength at break and volume resistivity were systematically studied. And,its mechanism was discussed.
