Description

一种有机硅聚碳酸酯型聚氨酯合成革及其制备方法
技术领域
本发明属于有机硅聚氨酯合成革领域，特别涉及一种有机硅聚碳酸酯型聚氨酯合成革及其制备方法。
背景技术
目前合成革材料有PVC合成革、聚氨酯合成革、有机硅合成革三大类，在其产品均具有一定的局限性：PVC合成革环保性能差、手感差、外观皮感差；聚氨酯合成革在紫外光作用下聚氨酯树脂会发生分子链断裂、分子降解，无法用于户外条件及一些工程类材料；有机硅合成革由于有机硅树脂很难兼顾耐磨性及延展性导致材料包覆性能差，有机硅不发泡材料手感僵硬做成的合成革材料手感也差。
现有技术中，并没有一种合成革能够同时兼备手感柔软、耐磨性能优异、弹性好等特点又具备有机硅材料的天然防污性、强耐光性能、强耐老化性等特点。同时，也没有一种合成革的制备材料适用范围广、综合性能优良，使得用其制备的成品革具有良好的防污家居及工程装饰的适用性。
普通聚氨酯材料强度及耐磨性能优于有机硅材料，但是如果要实现防污性能表面材料需要做到超高模量，通常手感僵硬、表面塑胶感重、材料脆、耐曲折性能及耐低温性能差。而硅橡胶材料具有优良的触感、防污、耐光性、耐老化性能；但材料强度低、耐磨性能差。硅橡胶材料为橡胶质感，通常为致密橡胶结构，与发泡聚氨酯结合以后可以大大改善手感。
