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。

Abstract:

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.

Key words: thermoplastic polyamide elastomer, ethylene?vinyl acetate copolymer, modification, cell structure, mechanical property
