有机硅丙烯酸酯聚氨酯三元共聚乳液的研究

Study on polyurethane emulsion modified by acrylic resin and silicone

采用丙烯酸树脂 (PA或PAr)、有机硅对水性聚氨酯进行改性 ,合成了一种有机硅丙烯酯聚氨酯聚合物。探讨了各种合成条件 ,如反应温度、NCO/OH值、引发剂浓度、-COOH用量。

The polysilicon-polyurethane-acrylic emulsion is prepared by copolymerization of multicomponent acrylate,silane and polyurethane.The influences such as the reaction temperature,initator,the mole ratio of NCO group and all OH groups,content of carboxyl,polysilicone on reaction were studied.
