将乙烯-辛烯共聚物(POE)应用于乙烯-醋酸乙烯共聚物(EVA)发泡材料中,考察了POE用量对POE/EVA复合发泡材料性能的影响。对发泡材料的泡孔结构进行扫描电子显微镜观察,对发泡材料的各项物理性能进行了测试。探讨发泡剂偶氮二甲酰胺(AC)、交联剂过氧化二异丙苯(DCP)、滑石粉等用量对POE/EVA复合发泡材料性能的影响规律,获得综合性能优良的高弹POE/EVA复合发泡材料的优化配方。

Ethylene-octene copolymer(POE) was melt blended with ethylene-vinyl acetate copolymer(EVA) at different composition ratios of POE/EVA.The blends were then melt mixed with foaming agent azodicarbonamide(AC),cross-linking agent dicumyl peroxide(DCP),and talcum powder to prepare foamed materials.The morphology of the foamed materials was investigated by scanning electron microscopy.The physical properties of the foamed materials were tested.The effects of the composition ratio of POE/EVA,and the amount of AC,DCP and talcum powder on the properties of the foamed POE/EVA materials were investigated.The formulation for a highly elastic EVA/POE foamed material was optimized.
