低密度环保型松糕鞋底用聚氨酯鞋底及其制备方法
技术领域
本发明涉及一种低密度环保型松糕鞋底用聚氨酯鞋底及其制备方法,属于聚氨酯材料技术领域。
背景技术
松糕鞋是一款新式高跟鞋,外观漂亮,穿着舒适,鞋底厚度一般为3-5cm,穿起来有点松软的感觉,仿佛踩在了松糕上,成为年轻女士的潮流之选。随着生活水平的改善,人们对鞋类产品的技术指标、舒适性等提出了越来越高的要求。相比于传统的乙烯-醋酸乙烯共聚物及聚氯乙烯材料,聚氨酯鞋底原液具有舒适、弹性好、耐磨等优点,受到更多的关注。追求低成本、高质量,是未来聚氨酯鞋底材料的发展方向。降低制品密度是聚氨酯鞋材供应商比较喜欢的方式。市场上的鞋底树脂用发泡剂主要是水和氟烃化合物,随着环保理念的深入,氟烃化合物已经受到严格的限制,全水发泡鞋底树脂备受青睐,另外,树脂的流动性较差,容易导致鞋底表面出现气泡,制品密度降低时又会收缩,致使表皮粗糙,影响松糕鞋的美观性。
