摘　　要：自制纳米SiO2溶胶,用硅烷偶联剂(乙烯基三乙氧基硅烷)进行表面处理,然后合成以纳米SiO2溶胶为核,聚苯乙烯、丙烯酸酯为壳的无机-有机复合乳液。结果表明,复合乳液制成的凃膜的力学性能及耐水性都得到了提高笛榛寡芯苛嗽谖藁⒘4嬖谙?苯丙乳液聚合的工艺条件。Preparing silicon dioxide sol, dealed the surface with silanizing coupling agent（triethoxyvinylsilance）.Synthesizing the emulsion which nano-silicon dioxide as core and St/BA as shell. We got the appropriate data（temperature 80℃, time〉24h）. The mechanical performance and water resistanle was enhanced. We also studied the technics of copolymerization emulsion
