摘要
以EVA为基体树脂,硅烷偶联剂KH-550改性氢氧化镁(MH)为主阻燃剂,三聚氰胺氰尿酸盐(MCA)为协效阻燃剂,添加相容剂MC328,制备了EVA复合材料,研究和对比了MCA、MC328含量对复合材料的力学性能、加工性能、燃烧、极限氧指数等性能的影响。结果表明:MCA的加入改善了体系力学性能及加工性能,提高了燃烧性能,但对氧指数有负面影响;而相容剂MC328的加入可以极大提高复合材料的力学性能及氧指数,但是降低了阻燃等级。
Using ethylene-vinyl acetate copolymer(EVA) as matrix resin,magnesium hydroxide(MH)modified by KH-550 as main flame retardant,melamine cyanurate(MCA) as synergistic flameretardant,a kind of EVA composite was prepared by adding compatibilizer(MC328). The effects of MCA and MC328 content on the mechanical properties,melt flow rate,vertical combustion and limiting oxygen index(LOI) of the composite were studied.The results show that the addition of MCA improves the mechanical properties,processability and vertical combustion property of the composite,but the LOI decreases.The addition of MC328 improves the mechanical properties and LOI of the composite,but the flame retardant grade decreases.
