摘要
本文采用聚己二酸-1,4-丁二醇酯(PBA)、六亚甲基二异氰酸酯(HDI)和异佛尔酮二异氰酸酯(IPDI)、乙二胺(EDA)等原料,通过添加N,N′-二(2,6-二异丙基苯基)碳二亚胺(DIPPC),制备了具有高耐水解性的聚氨酯分散体。研究表明,当N,N′-二(2,6-二异丙基苯基)碳二亚胺的添加量为1%时,聚酯型聚氨酯分散体具有较好的耐水解性能,可以满足在鞋材或汽车粘合领域高温高湿环境下的应用需求。
In this paper,poly(1,4-butanediol adipate)(PBA),hexamethylene diisocyanate(HDI),isophorone diisocyanate(IPDI)and ethylenediamine(EDA)were used as raw materials,polyurethane dispersions with high hydrolysis resistance were prepared by adding bis(2,6-diisopropylphenyl)-carbodiimide(DIPPC).The results show that the polyester type polyurethane dispersion has good hydrolysis resistance when the content of bis(2,6-diisopropylphenyl)-carbodiimide is 1%,which can meet the application requirements in high temperature and humid environment of shoe material or automobile bonding field.
