摘要:
采用蓖麻油(C.O.)、甲苯二异氰酸酯(TDI)和二羟甲基丙酸(DMPA)反应合成了水性聚氨酯(WPU)分散体,研究了n(—NCO)/n(—OH)、DMPA含量对聚氨酯乳液及涂膜性能的影响.实验表明:当n(—NCO)/n(—OH)为2.2∶1,DMPA添加量为7.0 %,反应温度为70℃,乳化温度为30 ℃时合成的水性聚氨酯涂料具有优良的成膜性、较高的硬度、良好的柔韧性和较好的疏水性.
Abstract:
Waterborne polyurethane (WPU) was prepared by the reaction of castor oil (C.O.) with dimethoxypropionic acid (DMPA) and toluene diisocyanate (TDI). The effects of molar ratios of —NCO to —OH and DMPA content on the properties were investigated. The result showed that the castor oil based waterborne polyurethane had excellent filmforming property, high hardness, excellent fallibility and good resistances to water. The best experiment conditions were as follows:molar ratio of n(—NCO)/n(—OH) was 2.2, DMPA content was 7.0 %, the temperatures of reaction and emulsification stage were 70 and 30 ℃, respectively.
