Description

一种改性热塑性聚酯弹性体、改性热塑性聚酯弹性体的EVA发 泡鞋底及其制备方法
技术领域
本发明涉及鞋底制作技术领域,更具体的涉及一种改性热塑性聚酯弹性体、改性热塑性聚酯弹性体的EVA发泡鞋底及其制备方法。
背景技术
随着鞋材行业的日渐成熟,鞋用发泡材料体系不断扩充,热塑性聚酯弹性体(TPEE)近年来发泡材料在鞋材方面得到越来越多的应用。TPEE是一类含有聚酯硬段和脂肪族聚酯或聚醚软段的线型嵌段共聚物,兼具橡胶优良的弹性和热塑性塑料的易加工性,硬软段的结合使其具有优异的抗弯曲耐疲劳性与耐冲击性。TPEE与乙烯-醋酸乙烯酯搭配使用可有效改善足底受力部位易塌陷且不易恢复、边墙易起皱等问题。但是,TPEE作为鞋材,如果直接与其他弹性体共混,其熔点过高,很难达到分子级别的相容,存在一定的风险,影响发泡材料的泡孔均匀程度及物理性能。同时,TPEE的熔体强度较低,在发泡过程中很难锁住泡孔内气体,易导致泡孔不均匀。
有鉴于此,本发明提出一种改性热塑性聚酯弹性体、改性热塑性聚酯弹性体的EVA发泡鞋底及其制备方法,通过对TPEE共混改性,发挥其优异的抗弯曲耐疲劳性与耐冲击性能,然后再与EVA共混发泡来解决鞋底足底受力部位易塌陷、边墙易起皱等问题。

S5. 注塑冷胚,将造好的料倒入注塑机内,喂料,第一、二、三、四区温度全部设置为95℃,将料量依据模具用量设定好,硫化时间为200-500秒,得到冷胚。
S6.发泡,将注塑冷胚放入发泡釜中发泡,先加温加压待注塑冷胚中气体饱和后再泄压即可得到发泡粗胚。其中实施I组别中,发泡釜的压力设置15MPa,温度设置145℃,气体饱和的时间为6h,泄压的时间为20s。 J组别中,发泡釜的压力设置14MPa,温度设置140℃,气体饱和的时间为5.5h,泄压的时间为15s。 K 组别中,发泡釜的压力设置13MPa,温度设置135℃,气体饱和的时间为4h,泄压的时间为10s。 L组别中,发泡釜的压力设置12MPa,温度设置145℃,气体饱和的时间为4h,泄压的时间为10s。 M组别中,发泡釜的压力设置15MPa,温度设置135℃,气体饱和的时间为6h,泄压的时间为15s。
S7.模压,将半成品脱模后压入平板模压模具内,即得到改性热塑性聚酯弹性体的EVA物理发泡鞋底。
针对本实施例配比得到的改性热塑性聚酯弹性体的EVA物理发泡鞋底,进行了抗疲劳性能实验测试,实验方法依照“GB/T 38018-2019 鞋类 鞋底测试方法 抗疲劳性能”,设置力值1200N,压缩次数40000次,对试样进行连续压缩。压缩测试结束后,测量疲劳压缩部位的厚度,得结果如下表所示。
