摘　　要：采用原位乳液聚合工艺,以聚乙醇为保护胶体,合成纳米二氧化硅(SiO_2)改性的聚醋酸乙烯酯(PVAc)乳液.通过优化实验确定了最佳实验条件,结果表明:复合乳化剂OP-10与SDS的配比为2/1,乳化剂K_2S_2O_8的用量为单体的1.0%,纳米SiO_2含量为单体3%,保护胶体PVA用量为单体的10%时,制备的胶乳的性能最好.Using in situ emulsion polymerization process,poly （vinyl acetate） （PVAc） emulsion modified nano- SiO2 was prepared using poly （ ethyl alcohol） as protective colloid. The best experimental conditions were determined by the optimization experiment. The results showed that in the preparation of nano silicon dioxide modified polyvinyl acetate emulsion, when the ratio of OP-10 and SDS was 2/1 ,the amount of emulsifier K2S2O8 was 1% of the total mass of the monomer,the content of nano- SiO2 was 3 % of the total mass of the monomer,and the amount of colloid PVA was 10% of the total mass of the monomer,the property of latex was best.
