一种水性聚氨酯及其制备方法和水性聚氨酯汽车内饰胶粘剂及其制备方法
摘要：
本发明涉及一种水性聚氨酯及其制备方法和水性聚氨酯汽车内饰胶粘剂及其制备方法，属于水性胶粘剂领域。解决现有水性聚氨酯耐水性差、机械性能差的技术问题。本发明提供的水性聚氨酯除了聚(碳酸酯?醚)多元醇，还包括聚己内酯多元醇和聚己二酸丁二醇酯多元醇。本发明还提供水性聚氨酯汽车内饰胶粘剂，包括水性聚氨、水性增稠剂、水性消泡剂、水性分散剂、AMP?95、滑石粉、钛白粉、气相白炭黑和水性固化剂。还提供水性聚氨酯和水性聚氨酯汽车内饰胶粘剂的制法。制得的水性聚氨酯汽车内饰胶粘剂的胶膜的剥离力为368N/cm～405N/cm，经过一个循环后的剥离力为327N/cm～385N/cm，经过4个循环的高低温冲击、湿热耐候性测试后，胶膜没有任何翘边和开胶，剥离力为290N/cm～348N/cm。
摘要（英）：

The invention relates to waterborne polyurethane, a preparation method thereof, a waterborne polyurethane automotive interior adhesive and a preparation method thereof, and belongs to the field of waterborne adhesives. The technical problem that existing waterborne polyurethane is poor in water resistence and poor in mechanical property is solved. The waterborne polyurethane comprises polycaprolactone polyol and poly ethylene succinate polyol besides poly(carbonic ester-ether)polyol. The invention further provides a waterborne polyurethane automotive interior adhesive which is prepared from waterborne polyurethane, a waterborne thickening agent, a waterborne defoaming agent, a waterborne dispersing agent, AMP-95, talcum powder, titanium dioxide, fumed silica and a water waterborne curing agent. The invention further provides a preparation method of the waterborne polyurethane automotive interior adhesive. The release force of a glue film of the prepared waterborne polyurethane automotive interior adhesive is 368 N/cm-405 N/cm, and the release force is 327 N/cm-385 N/cm after one cycle; after four cycles of high-low temperature impact and damp and hot weather resistance tests are carried out, the glue film is not warped or unglued, and the release force is 290 N/cm-348 N/cm.
