Based on the problem that the poor durable and weathering performance of lightweight insulation glass bead material, glass beads composite coating could be made with nano-TiO2. These methods such as X-ray diflraction, SEM, the FT-IR, etc were used to study the experiment of the glass bead composite coating, and the UV-shielding property and photocatalytic property of the composite coating were analyzed. The result indicated that giving 5% TiO2 could get the highest light absorption rate, and the best band of the UV-shielding property is from 470 run to 490 nm and the absorption rate of 0.074; FT-IR test's results showed that there was no new key produced on the nano-TiO2 modified interface, the modification of nano-TiO2 by sodium polyacrykte was just a surface coated phenomenon. Basic mechanical properties of composite coatings experiments show that glass beads nano-TiO2 coating owns the durability and good resistance to weathering.%基于轻质保温玻璃微珠材料界面的耐久、耐候性能差的问题,用纳米TiO2制备了玻璃微珠复合涂层.采用X-射线衍射、SEM、FT-IR等方法进行了玻璃微珠复合涂层的实验研究,分析了复合涂层的紫外屏蔽性能及光催化性能.结果表明:TiO2为5％时,光吸收率最高,紫外屏蔽性能最好的波段为470～490 nm,吸收率为0.074；红外光谱测试结果说明改性后的界面,纳米TiO2没有新键产生,纳米TiO2的聚丙烯酸钠改性属于表面包覆现象.复合涂层基本力学性能实验表明:玻璃微珠TiO2涂层的耐久、耐候性能良好.
