| 摘 要： | 采用气相二氧化硅(SiO2)协效硅烷偶联剂KH550改性氢氧化镁(KH550-MH)制备了无卤阻燃乙烯-醋酸乙烯酯共聚物(EVA)复合材料,对比了不同SiO2含量对复合材料体系力学性能、加工性能、燃烧性能的影响。结果表明:当KH550-MH占体系的47%、SiO2占体系的8%时,体系的阻燃等级为V-0级,断裂伸长率达到168%。

| Abstract: | A halogen-free flame retardant ethylene-vinyl acetate copolymer(EVA) composite was prepared with fumed silica(SiO2) and magnesium hydroxide(KH550-MH) modified by KH550.The effects of various SiO2 contents on the mechanical properties,processability,and combustion property of the composite were studied.The results show that when KH550-MH content is 47%,SiO2 content is 8% of the system,the flame-retardant level of the composite reaches V-0,and the elongation at break attains 168%. |
