| 摘 要： | 选用异佛尔酮二异氰酸酯（IPDI）、聚酯二元醇、二羟甲基丙酸（DMPA）、甲基丙烯酸－β－羟乙酯（HEMA）等为原料，采用阴离子自乳化法制备了紫外光（UV）固化水性聚氨酯丙烯酸酯乳液考察了n（-NCO）/n（-OH）、DMPA及HEMA质量分数对乳液性能的影响结果表明，n（-NCO）n（-OH）为1．4-1．5，DMPA的质量分数为4．5％时乳液性能最好．同时，HEMA质量分数越高，乳液黏度越小．

| Abstract: | The anionic polyester aqueous UV-curable polyurethane-acrylate was prepared by self-emulsifying process. It chooses raw materials such as isophorone diisocyanate （IPDI）,polyethene glycol and dimethylol propinic acid（DMPA）. Some influencing factors on the properties of waterborne polyurethane-acrylate emulsion have been fully studied, such as the mole ratio of--NCO/--OH,the mass fractions of DMPA and HEMA. The results show that when the mole ratio of--NCO/--OH is between 1.4 and 1.5,the mass fractions of DMPA is 4.5% ,the waterborne polyurethane-acrylate emulsion has the best properties. Meanwhile, the viscosity of the emulsion will become smaller with the increase of the mass fraction of HEMA. |
