采用不同含量的空心玻璃微珠（HGB）和氢氧化铝（ATH）制备了阻燃乙烯-醋酸乙烯酯共聚物（伊娃）复合材料，并采用极限氧指数、UL-94和锥形量热仪测试了复合材料的阻燃性能。结果表明，HGB含量为1.0 wt-%时，伊娃-4的热释放速率、总热释放速率和烟气生成速率最低，且HGB能促进试样表面形成致密的炭层。结果表明，HGB与ATH在该复合材料中具有明显的协同阻燃作用。
Flame retardant ethylene vinyl acetate (EVA) composites were prepared based on different contents of hollow glass beads (HGBs) and aluminium hydroxide (ATH) in this paper, and the flame retardant properties were studied using limiting oxygen index, UL-94 test and cone calorimeter test respectively. The results showed that EVA-4 with 1.0 wt-%HGBs has the lowest heat release rate, total heat release and smoke production rate among all samples, and HGBs could promote to form a compact char layer on the surface of the sample. It indicates that there is an obvious synergistic flame retardant effect between HGBs and ATH in this composite.
