摘要
采用异佛尔酮二异氰酸酯(IPDI)、聚醚硅氧烷二元醇(WACKER IM 22、IM15)/聚酯二元醇(7112)混合软段、二羟甲基丙酸(DMPA)/聚乙二醇(PEG600)混合亲水基(扩链剂)、季戊四醇三丙烯酸酯(PETA)等原料合成多官能度的综合改性UV固化水性聚氨酯丙烯酸酯(WPUA);实验结果表明:采用阴/非离子混合型亲水基能提高WPUA产品稳定性,改性产品固化后膜的耐水性、耐碱性、耐溶剂性能明显提高,综合性能优良。
A multifimctional modified UV-curable WPUA with mixed hydrophilic groups and was pre- pared from IPDI, polysiloxane (WACKER IM 22 or IM 15 ),/polyester diol (7112) , PETA and DMPA/po- lyethylene glycol (PEG600) hybrid hydrophilic chain extender. The results show that the use of cationic/ noninnic hybrid chain extender could improve the product stability as well as water resistance, solvent resist- ance, alkali resistance effectively.
