Description

聚氨酯鞋底及其制备方法
技术领域
本发明属于聚氨酯材料技术领域，具体的涉及一种聚氨酯鞋底及其制备方法。
背景技术
聚氨酯作为新型高分子材料，属于高科技、高性能、高附加值的产品。它作为鞋底材料，可以耐油、柔软、耐磨、整体轻便，具有保暖性和舒适性。但是现有聚氨酯鞋底绝缘，具有汗液无法排出、易脚热和产生静电，对人体健康产生不利的影响。
秋冬季节空气干燥，人们经常被静电伤害，本发明公开了一种鞋底，可以达到在普通地面上，将身体上的静电导入地下，大地的自由电子导入身体。人体大部分是由水和矿物质组成，是电子的良导体，当你穿现有的绝缘橡胶鞋底，阻隔了脚与大地的联系，造成“不接地气”。我们设计的鞋子整体***电阻值达到导电，但又不能像金属一样几乎无电阻，否则，快速流过人体的电流会对人体造成危险。
发明内容

A组份
B组份
MDI-聚酯预聚体 110份。
MDI-聚酯预聚体是4-4’-二苯基甲烷二异氰酸酯与分子量为2000的聚已二酸乙二醇酯的预聚体。
4-4’-二苯基甲烷二异氰酸酯的质量含量为93.8％。
所述的抗静电剂为季铵盐抗静电剂。
所述的抗静电剂为SC-1。
所述的聚氨酯鞋底的制备方法，步骤如下：
A组份制备步骤
将二官能度聚醚多元醇加入到四官能度多元醇中，然后添加三官能度聚合物多元醇；加入丙三醇、2-羟基-4-正辛氧基二苯甲酮和抗静电剂，搅拌15-20分钟，均匀形成A料。
B组份的制备
将4-4’-二苯基甲烷二异氰酸酯与聚已二酸乙二醇酯加入到反应釜反应即获得B组份。
聚氨酯鞋底制备步骤
B料MDI-聚酯预聚体加入A料，混合浇注成型，经过3-5min熟化而制得接地气防静电双向导通的聚氨酯鞋底。
作为一个优选的制备工艺，本发明所述的抗静电剂SC-1制备方法如下：
(1)在1000mL干燥的三口烧瓶中，加入300g聚乙二醇(PEG，分子量为1500)、环氧氯丙烷129g、质量分数50％的氢氧化钠水溶液50g、催化剂四丁基溴化铵3.2g，二氯甲烷80mL升温至50℃回流反应，然后剧烈搅拌4h，冷至室温，抽滤。加入无水硫酸钠干燥，抽滤。将滤液蒸馏除去溶剂二氯甲烷及未反应的环氧氯丙烷，得无色粘稠状粗品。上述产品不经纯化，直接用于下一步反应。
(2)在500mL干燥的三口烧瓶中，加入上述合成的所有粗品、三甲胺盐酸盐39g、乙醇60ml，于30℃搅拌反应3h。蒸馏除去溶剂得到粗品，残余物以乙酸乙酯重结晶，真空干燥后得抗静电剂SC-1。
本发明聚氨酯鞋底为接地气、防静电、双向导通的聚氨酯鞋底。
本发明鞋底的电阻是107-109Ω，既能保证我们的安全，又让我们穿上鞋子能达到身体上的静电与地面上自由电子双向导通，起到保护身体的作用。
与现有技术相比，本发明具有以下技术效果：
本发明聚氨酯鞋底，该鞋底无毒、环保、轻便、耐磨，具有防静电、接地气和自由电子双向导通的作用。能将人体产生静电导入大地，将大地负电子导入身体，起到中医讲的阴阳平衡的作用。
