摘　　要：选用高相对分子质量、结构中1,4-丁二醇(1.4BG)含量较少的聚酯二元醇,合成了高性能的湿法皮革用聚氨酯树脂。讨论了聚酯分子质量、种类等因素对聚氨酯弹性体性能的影响。所合成的聚氨酯物性高、凝固速度快、成肌性高,可明显提高皮革厂的生产效率,降低生产成本,同时保证皮革品质不受影响。A high performance PU resin for leather via wetting process has been prepared by using the polyester diol with high molecular weight comprising low content of moiety 1,4-butanediol. The effects of molecular weight and types of polyester on properties of PU elastomer are investigated. The prepared PU shows good physical performance, quick curing speed and good film-forming property, which can improve the productivity and reduce the production cost of leather, meanwhile, has no negative influence on quality of leather.
