摘　　要：研究了发泡剂用量对热塑性聚酰胺弹性体(TPAE)改性乙烯-醋酸乙烯共聚物(EVA)复合发泡材料(EVA/TPAE)的影响,并在最佳发泡剂用量下探究了EVA中TPAE的添加量对EVA/TPAE复合发泡材料发泡性能及力学性能的相关影响。结果表明,EVA/TPAE=100∶5(质量比,下同)时,EVA/TPAE共混物/发泡剂=100∶3的条件下,EVA/TPAE复合发泡材料体系发泡更完全,泡孔尺寸更均匀,且能满足目前发泡鞋材要求的力学强度;在该发泡剂用量下,仅添加少量的TPAE(EVA/TPAE=100∶5)就可获得综合性能良好的EVA/TPAE复合发泡材料,具有潜在的市场应用前景。This paper reported a study on the effect of addition amount of foaming agent on the ethylene-vinyl acetate copolymer(EVA) foaming materials modified with thermoplastic polyamide elastomer(TPAE),and the foaming performance and mechanical properties of the resulting EVA/TPAE foaming materials were also investigated at a fixed mass ratio of EVA to TPAE of 100 to 5. The results indicated that the foaming materials foamed more fully at a mass ratio of foaming material to foaming agent of 100 to 3,leading to a uniform cell size. The obtained foaming materials could meet the requirement of the shoe materials for mechanical strength. At this mass ratio,the foaming materials exhibited good comprehensive performance,suggesting a good application prospect in the shoe market.
