本发明有益效果：
本发明所述的水性聚氨酯鞋用复合材料，表皮层选择的水性聚氨酯，折纹细腻，满足耐曲折性能要求，满足表面滑爽要求,使成品有着较舒适的触感和良好的耐折性能。中间层采用低模量(100％伸长模量为1-3MPa)水性聚醚型聚氨酯树脂，连接表皮层与接着层，使无溶剂有着良好的熟化性能，使树脂之间结合紧密；使产品柔软舒适且粘结定型性好。接着层无溶剂树脂的优化选择，与中间层和布层结合，使产品具有较高的剥离力，让产品有着合适的手感。本发明所采用的水性聚氨酯树脂、无溶剂树脂均不含有害溶剂，避免了有机溶剂DMF的使用，能够控制成品中不含DMF，制得产品符合客户的DMF量控制在50ppm以内的要求，属于绿色环保产品。
本发明所述的水性聚氨酯鞋用复合材料，通过向水性聚氨酯结构中引入有机硅以提高其耐水性和热稳定性能，水性架桥剂采用异氰酸酯类水性架桥助剂，该基团会生成硅羟基，成膜干燥过程中硅羟基之间迅速缩合，形成网状结构不仅可以提高水性聚氨酯的耐水性，还可以大幅度提高其热稳定性，从而使得合成革耐磨耐水洗，抗粘连性、耐磨性明显提升，延长了使用寿命。
本发明所述的水性聚氨酯鞋用复合材料，通过在无溶剂浆料中添加超细亲水二氧化硅，赋予了产品超细均匀的孔洞，提高了水蒸汽透过量，改善其透气性能，同时通过添加非离子有机抗菌助剂提高抗菌除臭性能，从而保证穿着的舒适度。
本发明所述的水性聚氨酯鞋用复合材料的制备方法，减少了湿法的步骤，直接利用无溶剂树脂的发泡取代了湿法贝斯的制作，达到了节能减排的效果。本发明利用了聚醚分子结构的相似性和无溶剂树脂的交联反应，制得的水性聚氨酯鞋用复合材料具有较高的剥离力和良好的耐折性能。
