防水透气功能性聚氨酯合成革的研制

Study on the Preparation and Properties of the High Hydrolysis Resistance Polyurethane Synthetic Leather

介绍了一种防水透气功能性聚氨酯合成革的制造方法。通过在不织布上涂敷聚醚型聚氨酯浆料,经湿法凝聚成膜,水洗烘干后对表面进行磨削处理,然后通过离型纸转移法在表面转移一层同样具有防水透气功能的皮膜,从而得到成品革。性能分析结果表明:该产品具有类似天然真皮的透气功能,同时具有良好的耐水解性能、高剥离强度、高耐寒耐磨和防水性能,手感柔软,弹性佳,耐用性好,可用于制作高档运动鞋、特殊行业用鞋以及沙发家具等。

A functional polyurethane waterproof breathable leather manufacturing method,through in nonwoven on coated polyether polyurethane pulp by wet method converge into membrane,washing and drying,to surface grinding processing,and then through parting paper transfer method in the surface layer transfer also has waterproof breathable function of skin membrane,where get finished leathers.The performance analysis results show that the product has similar natural ventilation function of leather,and has good resistance to hydrolysis performance,high peel strength,high cold-resistant wear-resisting and waterproof performance,feel soft,good elasticity,durable sex good,can be used to produce high-grade sneakers,special industries with shoes and sofa furniture etc.
