摘要：

将叔胺位于主链的N-甲基二乙醇胺(MDEA)和叔胺位于侧基的7,12-二氧-3,16-二氮-3,16-二乙基-5,14-十八二醇(DDDOD)分别作为亲水单体,与聚己内酯二元醇(PCL)、异佛尔酮二异氰酸酯(IPDI)等反应,制备聚氨酯分散体。通过聚氨酯的分散性、分散体平均粒径,比较了亲水基位于聚氨酯主链和侧基的两种单体的亲水性。结果表明,亲水基团位于侧基时,亲水效果比位于主链的好。将叔氨基位于侧基的单体DDDOD作为亲水单体,与PCL、IPDI反应,制备了聚氨酯,加入UV固化单体,分散得到UV固化的阴极电泳涂料。研究了涂料的乳液性能和UV固化后双键转化率和膜性能。

Abstract:

N-Methyldiethanolamine (MDEA) bearing main chain tertiary amine and 7,12-dioxa-3,16-diaza- 3,16-diethyl-5,14-octadecanediol (DDDOD) bearing pendant tertiary amine were used as the hydrophilic monomers, respectively to prepare polyurethane dispersions. Hydrophilcity of the two hydrophilic monomers was compared by the dispersibilities of the polyurethanes and mean diameters of the dispersions. The results showed that DDDOD had a better hydrophilcity than MDEA, revealing that hydrophilic monomer with pendant tertiary amine had a superior hydrophilic ability than that with backbone tertiary amine. Polyurethane was prepared by the reaction between DDDOD, poly-caprolaclone glycol(PCL) and isophorone diisocyanate (IPDI). UV-curable monomers were added into the polyurethane and dispersed together. The properties of the dispersions and films were studied. The conversion of carbon-carbon double bonds after UV-curing was analyzed.

Key words: diol with pendent tertiary amine, hydrophilcity, UV-curable cathodic electrophoretic coatings, emulsions, size distribution, synthesis
