摘要
以1,4-丁二醇(BDO)、二羟甲基丙酸(DMPA)和乙二胺(EDA)为扩链剂,蓖麻油(C.O.)为内交联剂,以甲基丙烯酸甲酯(MMA)和丙烯酸丁酯(BA)改性聚氨酯(PU)制得水性聚氨酯-丙烯酸酯复合乳液(PUA)。研究了C.O.、DMPA和BA对乳液及涂膜性能的影响。
The waterborne polyurethane-acrylate complex emulsion modified by methyl methacrylate(MMA)and butyl acrylate(BA)copolymer were synthesized by using 1,4-butanediol(BDO),dimethylolpropionic(DMPA)and ethylenediamine (EDA)as chain extenders,castor oil(C.O.)as inner-crosslinking agent.The influences of the interrelated material on the properties of complex emulsion were studied.
