摘　　要： 采用天然的蓖麻油与聚醚(N 210)、聚乙二醇(Mn=1000)、甲苯二异氰酸酯、二乙烯三胺、环氧氯丙烷、马来酸酐等为原料,通过丙酮法制得稳定的水性聚氨酯乳液。提出了聚合反应的机理,研究了亲水单体对聚氨酯乳液的粘度、稳定性、乳液成膜的干燥时间、膜的耐水性的影响。结果表明,通过改变亲水单体的含量,可以制得稳定、适用的聚氨酯乳液。 Stable waterborne polyurethane emulsions were prepared with castor oil, polyuther glycol(N210), polyethylene glycol(Mn=1000), TDI, diethylene triamine, epoxy chloropropane and maleic anhydride(MAH) by means of acetone process. Mechanism of polymerization was presented and effects of hydrophilic monomers such as diethylene triamine, epoxy chloropropane and MAH on viscosity, stability, drying time of film forming and water resistance of film for polyurethane emulsions were investigated.the results showed that stable, appropriate polyurethane emulsions could be obtained by way of changing content of hydrophilic monomers as epoxy chloropropane and MAH.
