纳米苯丙阳离子乳液型纸张表面施胶剂

Study on nano cationic poly(St/BA) emulsion as paper surface sizing agent

以苯乙烯、丙烯酸丁酯为主单体加入少量的自制阳离子Gemini乳化剂,分别采用单体半连续滴加法、间歇式加料法、单体全滴加加料法合成黏度小、固含量为30%的稳定的纳米阳离子聚合物乳液并直接用于纸张表面施胶施胶效果好为开拓微乳液在造纸施胶剂中的应用提供了有价值的理论根据。,,,,

In this paper,the nano cationic polymer emulsion of styrene and butyl acrylate as the basic monomers was synthesized by adding a small amount of the Gemini cationic emulsifier using interval feeding,semi-continuous and continuous dropwise adding methods.The cationic emulsion has good stability,solid content of 30% and low viscosity.And the emulsion was directly used for paper surface sizing agent,the sizing effect was good.It provides a valuable theoretical basis for the development of micro emulsion in paper sizing agent application.
