Description

一种造鞋用PU合成革及其制备方法
技术领域
本发明涉及合成革制造领域，尤其涉及一种造鞋用PU合成革及其制备方法。
背景技术
目前国内人造合成革的制造过程中，无论基材或面皮的制造均使用了大量的有机溶剂，PU树脂通过甲苯、二甲苯、丙酮、丁酮、乙酸乙酯、二甲基甲酰胺等作为主要溶剂以溶剂聚合法制得，这些有机溶剂都是有害物质，据统计，一条合成革生产线日均需消耗 10 吨左右的溶剂型PU树脂，其中占溶剂型树脂总用量 60%以上的是溶剂，虽然湿法生产线中85%左右的溶剂被回收，但湿法生产线中仍有15%左右、干法95% 的溶剂无法回收，将通过水和空气排放到周边的河流和天空中，其会造成严重的环境污染，给人们的生命健康构成重大威胁。如湿式合成革使用的溶剂中含有二甲基甲酰胺，可经由皮肤吸收或由肺吸入会导致中毒，依规定采用这种方法合成革工厂必须设有废气和废水处理的设备，工厂必须随时进行监控和记录其处理过程，废气和废水的处理相当费时费力，而且成本较高，稍有不慎就会造成严重的污染后果。
发明内容
针对现有技术中的上述不足，本发明提供了一种造鞋用PU合成革及其制备方法，其制备简单，其不会造成环境污染、无重金属元素带入，不会给人们的健康带来影响，而且具有优良的耐曲折性。

优选地所述造鞋用PU合成革的制备包括以下步骤：
（1）将配比的聚氨酯树脂、增稠剂、色粉及溶剂混合搅拌，制备树脂层；
（2）将步骤（1）中制备的树脂层刮涂在离型纸上，进行加温固化，然后过水冷却，蒸汽烘干，温度控制在80-130℃；
（3）将粘合剂层刮涂在经过步骤（2）后的图层上，温度控制在90-110℃烘干；
（4）将基布层贴合在经过步骤（3）后的图层上，温度控制在90-160℃，烘干后形成树脂层和基布层；
（5）去除离型纸，再冷风冷却，定型，收卷，包装得到 PU合成革。
优选地，所述溶剂为乙烯乙二醇醚。
优选地，所述色粉为钛白粉。
