| 摘 要： | 设计了一种改性纳米TiO2方法，先用带双键官能团的硅烷偶联剂WD70和纳米TiO2反应后，在颗粒表面引入可聚合官能团，然后和甲基丙烯酸甲酯、丙烯酸丁酯共聚合使纳米TiO2颗粒改性.研究结果表明，改性提高了纳米颗粒在涂料中的分散程度，降低了涂层的吸水性和透气性.

| Abstract: | A method is designed to modify nano-TiO2 particles, by which nanoparticles are modified by silane coupling agent WD-70 with double bond group and then the silane coupling agent copolymerizes with methyl methacrylate and butyl acrylate to produce a thin polymer shell on the nanoparticles. The modified nanoparticles are applied as pigment to polyacrylate coating. The modification of nano-TiO2 can improve its dispersibility in the coating and thereby reduce water absorption and permeability of the polyacrylate coating. |

| Keywords: | nano-TiO2 modification polyacrylate coating water absorption permeability |
