Description

一种环保PU革
技术领域
本发明涉及一种PU革。 
技术背景
合成革在制革加工过程中通常使用油性树脂以及重金属元素，而油性树脂中一般都有含有0.5-2.5％异氰酸酯残留，异氰酸酯具有很大的毒性，在生产应用过程中，这些物质对操作工来说，就是毒源和接触到的致命物质。另外，油性树脂中含有大量的有机溶剂，这些有机溶剂也是有毒有害的，它不仅在生产过程中危害人体、污染环境，而且还残留在革的空隙中，其制品也有害于人体。 
发明内容
本发明所要解决的技术问题就是提供一种环保PU革，不含有毒树脂、有机溶剂和重金属元素，更加绿色环保，并且皮革更加牢固耐磨。 
为解决上述技术问题，本发明采用如下技术方案： 
一种环保PU革，包括基布层，所述基布层上复合设置有由阳离子型水性聚氨酯构成的底涂层，所述底涂层上涂覆有由阴离子型水性聚氨酯构成的粘接层，所述粘接层上复合设置有由阳离子型水性聚氨酯构成的中涂层，所述中涂层上复合设置有水性聚氨酯面层。 
优选的，所述阳离子型水性聚氨酯为羟基硅油改性阳离子水性聚氨酯，所述阳离子型水性聚氨酯中包含有聚二甲基硅氧烷甲苯氨基甲酸酯。 
优选的，所述基布层由纤度为5～7旦的海岛型尼龙超细纤维经聚氨酯浆料含浸制成。 
本发明的有益效果为： 
本发明中的底涂层、粘接层、中涂层和面层均采用水性聚氨酯构成，不含 有异氰酸酯、重金属元素和有机溶剂，更加绿色环保，水性聚氨酯具有大量微孔，具有良好的透湿透气性能，而底涂层由阳离子型水性聚氨酯构成，粘接层由阴离子型水性聚氨酯构成，中涂层由阳离子型水性聚氨酯构成，形成了阳阴阳的三层间隔结构，通过阴、阳电荷电价力的作用，能提高涂层间结合的牢固度，使皮革更加牢固耐磨。 
附图说明
以下结合附图和具体实施方式对本发明进行进一步描述： 
图1是本发明的结构示意图。 
具体实施方式
下面结合附图对本发明的具体实施方式作详细说明。 
如图1所示，本发明包括基布层1，所述基布层上复合设置有由阳离子型水性聚氨酯构成的底涂层2，所述底涂层上涂覆有由阴离子型水性聚氨酯构成的粘接层3，所述粘接层上复合设置有由阳离子型水性聚氨酯构成的中涂层4，所述中涂层上复合设置有水性聚氨酯面层5。所述阳离子型水性聚氨酯为羟基硅油改性阳离子水性聚氨酯，所述阳离子型水性聚氨酯中包含有聚二甲基硅氧烷甲苯氨基甲酸酯。所述基布层1由纤度为5～7旦的海岛型尼龙超细纤维经聚氨酯浆料含浸制成。所述的阴离子型水性聚氨酯和面层5采用的水性聚氨酯均采用制革领域现有的聚氨酯材料。 
所述底涂层、粘接层、中涂层和面层均采用水性聚氨酯构成，不含有异氰酸酯、重金属元素和有机溶剂，更加绿色环保，水性聚氨酯具有大量微孔，具有良好的透湿透气性能，而底涂层由阳离子型水性聚氨酯构成，粘接层由阴离子型水性聚氨酯构成，中涂层由阳离子型水性聚氨酯构成，形成了阳阴阳的三层间隔结构，通过阴、阳电荷电价力的作用，能提高涂层间结合的牢固度，使 皮革更加牢固耐磨。 
以上就本发明较佳的实施例做了说明，但不能理解为是对权利要求的限制。本发明不仅局限于以上实施例，其具体结构允许有变化，本领域技术人员可以根据本发明作出各种改变和变形，只要不脱离本发明的精神，均属于本发明所附权利要求所定义的范围。
