一种用于真皮表面处理的涂料
技术领域  本发明涉及一种用于真皮表面处理的涂料，其特征在于有如下的组成：聚醚、聚四亚甲基醚二醇、异佛尔酮二异氰酸酯、丁二醇、二羟甲基丙酸、有机铋催化剂、三乙胺、尿素和去离子水。本发明属于真皮表面处理技术领域，更具体是涉及一种真皮表面的涂料及其制备工艺。
背景技术 真皮广泛应用于人们生活中，如真皮皮包、真皮皮衣、真皮沙发等。在一般在自然条件下，这些真皮的表面容易沾灰的，灰尘、汗渍、油污、茶水等沾到皮层上面后，容易造成皮层的霉烂、开裂、褶皱。真品都是取于动物的表皮，跟人的皮肤相同，都是要做好清洁保养，得到所需营养成分，才会更柔软、光滑、不易磨损划伤等。而真皮表面的处理就显得至关重要。除此之外，真皮表面本身并不光洁，需要进行特别的处理，才能使得真皮表面具有一定的光洁度。
发明内容 本发明的目的是提供一种用于真皮表面处理的涂料，该涂料具有成膜柔软、高光的作用，对真皮有极佳的柔顺手感。为达到上述目的，本发明具体的技术方案如下：
本发明具有如下的配方（质量百分比%）：聚醚10～ 20、聚四亚甲基醚二醇15～45、异佛尔酮二异氰酸酯10～40、丁二醇1～7、二羟甲基丙酸3～13、有机铋催化剂0.1～1、三乙胺1～9、尿素1～10，其余为去离子水。
其具体制备工艺如下：
（1）先将聚醚、聚四亚甲基醚二醇投入反应釜中，加热到110～120℃，然后抽真空脱水30～60 分钟；
（2）将上述混合物降温到85℃，加入有机铋崔化剂搅拌10 分钟；
（3）再向上述混合物中加入异佛尔酮二异氰酸酯，维持温度70～90℃，保温120～180 分钟；
（4）然后在上述温合物中加入丁二醇、二羟甲基丙酸及适量的丙酮，维持温度70～90℃，保温180～240 分钟继续反应；取样检测异氰酸酯基含量（NCO），使其含量维持在0.5 ～4.3%；
（5）然后将上述混合物冷却到40℃，加入三乙胺及丙酮，搅拌10～30 分钟；
（6）在上述搅拌的同时，加入已混合尿素的去离子水；
（7）继续搅拌60～120 分钟，真空抽去丙酮，即可得到成品。
本发明的有益效果在于：用上述方法生产成的用于真皮表面处理的涂料具有柔软性好、耐光性、耐水性好，伸长率达到1000～1500%。用该涂料处理过的真皮具有极佳的柔顺手感、耐化学性、耐磨，具有高拉伸、高伸长率、耐水耐湿、抗紫外线、不黄变、高光。本涂料树脂对TPU、PU革、PVC、PC、尼龙布、莱卡、高弹力布附着力佳。
