| 摘 要： | 以水性聚氨酯(WPU)为高分子乳化剂进行丙烯酸酯乳液聚合,制备了聚氨酯-丙烯酸酯(PUA)复合乳胶,探讨了影响乳胶粒径、黏度、稳定性、涂膜附着力和光泽度等性能的因素．此外,还将PUA乳胶和由小分子乳化剂制备的聚丙烯酸酯乳胶的稳定性和涂膜附着力进行了比较．结果表明,以WPU为乳化剂制备的乳胶稳定性和涂膜附着力优于用小分子乳化剂制得的乳胶．

| Abstract: | A series of polyacrylate emulsions were prepared with water-borne polyurethane(WPU)as emulsifier.Partical size, viscosity,stability,adhesive force and gloss of film were tested.Furthermore.a series of polyacrylate emulsions which used small molecule emulsifier were synthesized.The results show that the emulsion which was emulsified by the polyurethane was far better than the one which was emulsified by small molecule emulsifier on the stability and adhesive force. |
