Description

一种注塑用水性聚氨酯静电植绒胶及制备方法
技术领域
本发明涉及纺织胶黏剂技术领域，具体涉及一种注塑用水性聚氨酯静电植绒胶及制备方法。
背景技术
随着社会的发展，环保越来越受到人们的重视，水性产品对环境无污染、对人体无伤害，所以水性聚氨酯代替溶剂型聚氨酯已成为必然趋势。
目前市场上注塑用植绒胶以溶剂型聚氨酯为主，注塑牢度好，得到广泛使用，但溶剂型聚氨酯含有大量DMF、甲苯等溶剂，生产及使用过程会放出有害物质，对人体会造成伤害，对环境会产生污染。
发明内容
为此，本发明提供一种注塑用水性聚氨酯静电植绒胶及制备方法，以解决现有注塑用植绒胶以溶剂型聚氨酯为主而存在生产及使用过程会放出有害物质，对人体会造成伤害，对环境会产生污染的问题。
为了实现上述目的，本发明提供如下技术方案：
根据本发明的第一方面，一种注塑用水性聚氨酯静电植绒胶，所述静电植绒胶由如下重量份数的原料制备而成：

Figure BDA0002865941960000021
本发明通过选择二苯基甲烷二异氰酸酯和1，6-六甲基二异氰酸酯两种活性异氰酸酯基团协同作用提高牢度和初粘性、耐溶剂性能。原料二苯基甲烷二异氰酸酯具有环状结构，合成过程中环状结构稳定，形成高聚物后仍能存在，此结构可以增加产品的刚性，弹性好，耐水、耐溶剂、耐磨性能得到增强，改善植绒面料牢度、耐溶剂性能，1，6-六甲基二异氰酸酯是直链结构，降低产品热熔温度，同时提高初粘性。
聚酯结构具有耐溶剂好的特性，特别是具有偶碳链(偶碳原子数大于4)的聚酯、聚己内酯、聚碳酸酯具有好的粘结牢度及耐水解、耐溶剂性能。
聚醚链段的醚键在低温下极性低，可以自由旋转，耐寒性好。
聚酯、聚醚的优选配比，使产品耐寒、耐溶剂、牢度同时满足。
磺酸盐改性二异氰酸酯的使用，在提供亲水链段的同时，能有效降低活化温度，且其热熔温度低，有利于注塑；另外，由于磺酸盐独有特性，耐强碱、强酸，耐水解、耐老化性得到保证。
采用小分子多元醇和多元胺扩链提高了耐水、耐溶剂、耐磨性能，胺类扩链剂参与扩链得到水性聚氨酯是聚氨酯--脲乳液(分散液)，聚氨酯--脲比纯聚氨酯有更大的内聚力和粘接力，脲键的耐水性比氨酯键好，能改善干、湿牢度。
进一步地，所述聚酯多元醇选自1，6-己二醇—己二酸共聚二元醇、1，4-丁二醇—己二酸共聚多元醇、1，4-丁二醇-1，6己二醇—己二酸共聚多元醇、1，4-丁二醇-新戊二醇—己二酸共聚多元醇、1，6-己二醇-新戊二醇—己二酸共聚多元醇、聚碳酸酯多元醇、聚己内酯多元醇中的一种或者两种。

进一步地，所述聚醚多元醇的分子量为500-4000。
进一步地，所述磺酸盐改性二异氰酸酯选自北京佰源化工的产品。

进一步地，所述多元胺扩链剂选自乙二胺、二乙烯三胺、三乙烯四胺、水合肼、异佛尔酮二胺中的一种或两种。
进一步地，所述静电植绒胶的化学指标如下：
外观：白色蓝光乳液；
离子性：阴；
pH值：8±1；
固含量：50±2％。
根据本发明的第二方面，上述的静电植绒胶的制备方法，所述制备方法包括如下步骤：
S1、预聚反应：将二苯基甲烷二异氰酸酯、1，6-六甲基二异氰酸酯、聚酯多元醇、聚醚多元醇加入反应釜中，升温至85±2℃反应1.5-2小时，然后加入磺酸盐改性二异氰酸酯WTDI，在90±2℃反应3-4小时，得到预聚体；
