摘　　要：采用无机-有机氧基硅烷改性丙烯酸酯合成了无机-有机杂化硅丙乳液,通过单体预乳化的半连续核壳乳液聚合工艺,研究了反应温度、乳化剂含量、引发剂含量、无机-有机硅丙溶液含量和软硬单体质量比等对其转化率和性能的影响。结果显示,当无机-有机硅丙溶液质量分数为10%,乳化剂的质量分数2.9%,软硬单体质量比为1∶1,反应温度为80℃时,合成的无机-有机杂化硅丙乳液具有良好的综合性能,制得的防涂鸦抗粘贴涂料各项技术指标结果均可达到甚至超过标准要求,满足市政工程和家装领域的应用需求。In this paper,inorganic-organic hybrid silicon emulsion was synthesized with inorganic organoxysilane modified acrylate by means of semi-continuous core-shell emulsion polymerization process with monomer pre-emulsification.The effects of reaction temperature,emulsifier content,initiator content,inorganic-silicone propyl solution content and mass ratio of soft and hard monomers on the conversion and properties of the inorganic-organic hybrid silicon-acrylic emulsion were studied.The result showed that when the mass fraction of the solution is 10%,the mass fraction of the emulsifier is 2.9%,the mass ratio of the soft and hard monomer is 1∶1,and the reaction temperature is 80℃,the synthetic inorganic-organic hybrid silicon-acrylic emulsion has good comprehensive properties.The technical index results of the obtained anti-graffiti and anti-paste coatings can meet or even exceed the standard requirements,and meet the application needs of municipal engineering and home improvement fields.
