摘　　要：以苯乙烯(St)、丙烯酸丁酯(BA)为单体,十六烷三甲基溴化铵(CTAB)为阳离子乳化剂,乳化剂OP-10为乳化剂,过硫酸铵(APS)为引发剂,分别加入气凝胶、纳米二氧化硅、蒙脱土3种纳米材料,采用乳液聚合技术合成了阳离子表面施胶剂。较优合成组分是:m(St):m(BA)=1.5;w(CTAB)=2.8%;w(OP-10)=1%,w(蒙脱土)=0.5%。并主要对施胶纸张的印刷性能做了测试,与同等条件下未加纳米填料的表面施胶剂相比,纸张的色密度明显提高。The cationic emulsion type surface sizing agent was synthesized through emulsion polymerization technique, by using sryrene（St） and butyl acrylate（BA） as monomers, cetyltrimethylammonium bromide（CTAB） as cationic emulsifier, Emulsifier OP-10 as emulsifier, ammonium persulfate as initiator. Meanwhile, aerogel, nano-silica and montmorillonite were added. e better synthesis conditions are as follows： m（St）：m（BA）=1.5; w（CTAB）=2.78%; w（OP-10）=1%, w（montmorillonite）=0.5%. And through testing the printing performance of papers, the color density of paper can improve obviously. It is better then that of the same condition of product without nano-fillers.
