本文采用TiO2改性和乳液聚合法制备纳米TiO2/丙烯酸酯复合乳液，对纳米TiO2改性方法、纳米TiO2的含量以及复合方式等因素对乳液各种性能进行探讨。结果表明KH-570和二甲苯改性的纳米TiO2在水和无水乙醇溶剂中有较好的分散性和稳定性。用化学法制备的乳液，涂膜力学等性能优于物理共混法制备的，当纳米TiO2含量在2%，乳液成膜硬度最高，大于2H。

Answer 1

This article uses the TiO2 modification and the emulsion polymerization legal system prepares the nanometer TiO2/acrylic ester compound emulsion, to nanometer TiO2 modified factors and so on method, nanometer TiO2 content as well as compound way carries on the discussion to emulsion each performance. The result indicated that KH-570 and xylene modified nanometer TiO2 has the good dispersivity and the stability in the water and the absolute ethyl alcohol resolver. With the chemical process preparation's emulsion, performance and so on paint film mechanics surpass the physical blending law preparation, when the nanometer TiO2 content in 2%, the emulsion becomes the membrane degree of hardness to be highest, is bigger than 2H.
