| 摘 要： | 以甲苯二异氰酸酯(TDI)、聚醚二元醇(N-220)、1,4-丁二醇(BDO)、二羟甲基丙酸(DMPA)和硅烷偶联剂(KH-550)等为主要原料,采用丙酮法合成了有机硅改性WPU(水性聚氨酯)乳液。结果表明:KH-550和DMPA的加料方式对WPU乳液稳定性影响较大;当w(DMPA)=3%～5%时,WPU乳液及其胶膜的综合性能较好。

| Abstract: | With toluene diisocyanate(TDI),polyether diols(N-220),1,4-butanediol(BDO),dimethylolpropionic acid(DMPA) and silane coupler(KH-550) as main raw materials,so a WPU(waterborne polyurethane) emulsion modified by organic silicone was synthesized by acetone method.The results showed that the influences of feeding mode between KH-550 and DMPA on stability of WPU emulsion were larger.The WPU emulsion and film had better combination property when mass fraction of DMPA was 3%-5%. |
