摘要： 用硅氧烷改性纳米氧化锌与甲基丙烯酸甲酯、丙烯酸乙酯制备了无机-有机复合乳液。对比了5个复合乳液制备工艺的实验效果，最终采用过硫酸钾 -亚硫酸氢钠氧化还原引发体系和分段控温的乳液聚合工艺。进一 步优化了乳化剂的配比和用量、反应前后段温度与时间、引发剂的用量、纳米氧化锌分散时间、预乳化时间、聚合过程中的搅拌速度等乳液聚合工艺参数，得到了制备无 机-有机复合乳液的最佳工艺参数。

Abstract: The title inorganic-organic composite emulsion was prepared by using siloxane modified nanozinc oxide, methyl methaerylate and ethyl acrylate as the raw materials. The results of five emulsion polymerization processes were compared with each other. The potassium persulphate-sodium bisulfite redox initiator system and sectional temperature control polymerization process were adopted. The technical parameters, i. e. ratio and amount of the emulsifiers,sectionaltemperature and reaction time of the emulsion polymerization, dosage of the initiator, dispersion time of nano-zno and the pre-emulsion time, stiming speed during polymerization, were optimized. The optimum technical parameters were given.
