Description

一种用于鞋帮制品的海绵及其制备工艺
技术领域
本发明涉及一种用于鞋帮制品的海绵及其制备工艺，属于海绵制品技术领域。
背景技术
在鞋底上所有部分，缝制或采用其它他方法结合成为一个整体单元，与内底和外底结合称之为鞋帮。鞋帮为一双鞋的基本部分，由前帮或鞋的前部，后帮即鞋的侧面和后部，以及为加强鞋面用的鞋里构成。帮面可以使用各种材质，可以是天然皮革、人造合成材料或织物等。因为皮革上的毛孔，使皮革有良好的透气性，从而能使脚保持凉爽，所以皮革有帮面在帮面材料的选择上具有明显的优势。动物皮的塑性进一步适应脚的形状，使脚进行呼吸和有助于脚功能的发挥。在大规模生产中合成材料比较便宜，为常用的材料。但帮面为合成材料时，表现出来的是弹性性能，这意味着鞋帮面不会像皮革一样符合脚的开卷。
发明内容
本发明的目的在于解决上述已有技术存在的不足之处，提供一种弹性好、透气性好、不易变形、耐久度高的用于鞋帮制品的海绵及其制备工艺。
本发明是通过以下技术方案实现的：
一种用于鞋帮制品的海绵，其特殊之处在于由以下按重量份配比的原料制成：聚醚多元醇60-120份、甲苯二异氰酸酯80-100份、硅油0.5-1.5份、复合催化剂1.8-3份、发泡剂0.8-1.2份、扩链剂5-8.5份、开孔剂0.5-1.5份；
所述的复合催化剂为N，N-二甲基苄胺、四甲基己二胺和辛酸亚锡的复合物；
所述的发泡剂为二氧化碳、二氯甲烷和水的复合物；
所述的扩链剂为甘油；
所述的开孔剂为气相二氧化硅和聚丁二烯的复合物；
所述一种用于鞋帮制品的海绵，由以下按重量份最优配比的原料制成：聚醚多元醇90份、甲苯二异氰酸酯90份、硅油1.2份、复合催化剂2.5份、发泡剂1份、扩链剂7.5份、开孔剂1.2份；
一种用于鞋帮制品的海绵的制备工艺，其特殊之处在于包括以下步骤：
(1)将聚醚多元醇、甲苯二异氰酸酯、硅油、复合催化剂、发泡剂、扩链剂、开孔剂按比例倒入到反应釜进行搅拌，搅拌转速为3000-4000r/min，温度为16-28℃，得到混合物；
(2)将步骤(1)的混合物放入模具中发泡成型、熟化2-3分钟，脱模得到海绵胚体；
(3)将步骤(2)的海绵胚体自然冷却，放入打孔机中打孔，孔的直径为0.1-0.2mm，密度为6-12个/cm2，得到半成品海绵；
(4)将步骤(3)的半成品海绵压缩切割，包装即可。
本发明的一种用于鞋帮制品的海绵，制作简单、物美价廉，其良好的慢回弹性能，不但能够适应脚的形状，从而提升脚部的舒适性，而且具有良好的耐久性，从而提升鞋帮的使用时限，其中的密孔也使其具备了良好的透气性，从而保持鞋帮内的凉爽。
