摘　　要：采用浇注刮涂的方法制备了不同类型的浇注型聚氨酯(CPU)发泡涂层,研究了不同类型的多元醇对浇注型聚氨酯发泡涂层结构与性能的影响。研究结果表明:聚碳酸酯型CPU发泡涂层的力学性能最优,聚醚型CPU发泡涂层的力学性能最差;扫描电镜(SEM)图片表明,聚酯型CPU发泡涂层具有贯通的微孔结构,具有良好的透气性和透水汽性,卫生性能明显优于传统的聚氨酯湿法涂层;采用浇注刮涂法制备CPU发泡涂层用于合成革的生产,可以不使用任何有机溶剂,是一种清洁的生产技术。Different types of casting polyurethane （CPU） foam coating was prepared by pouring and scratching. The effects of different types of polymeric polyol on the CPU＇s structure and performance were studied. The results show that the mechanical properties of polycarbonate - type CPU foam coating is optimal, and polyether - type CPU foam coating is the worst. The scanning SEM photographs show that the bubbles of polyester type CPU foam coating are mostly through - hole which make the foam coating has good air permeability and water vapor transmission, and the health performance is superior to the traditional wet polyurethane coating. By using the technology of casting coating to prepare CPU foam coating used in the production of the synthetic leather, it is no need to use any organic solvent, which is a clean production technology.
