摘　　要：采用无皂乳液聚合技术和溶胶凝胶技术,合成了有机硅及纳米二氧化硅改性丙烯酸树脂无皂乳液。考察了反应性乳化剂用量、乙烯基硅油用量和纳米SiO2含量对乳液和膜性能的影响,结果表明:当反应性乳化剂的质量分数为3.5%,乙烯基硅油的质量分数为8%,纳米SiO2含量为6%时,乳液和膜的综合性能最优。通过在牛鞋面革上的涂饰应用试验证实,该涂饰剂具有优良的透水汽性、耐水性、耐干湿擦性、耐曲折和耐磨耗性,是一种具有良好应用前景的皮革涂饰材料。Nano - silica/silicone modified acrylic resin was synthesized by emulsifier - free emulsion polymerization and sol - gel technique. The influences of some parameters such as the dosage of reactive emulsifier, the dosage of vinylsilicone oil and the content of nano - silica on properties of emulsion and film were studied. By evaluating the obtained resuhs, the optimal synthesis formula is obtained as follows： the mass fraction of 3.5% reactive emulsifier, 8% vinylsilicone oil and 6% nano- silica. Theshoes upper leather treated with this finishing agent show enhanced water vapor permeability, good water resistance, rub resist- ance, flex resistance and attrition resistance properties, indicating that this nano - SiO2/silicone modified acrylic resin emulsifier - free emulsion has a promising application prospect in leather finishing.
