玻璃微珠TiO_2涂层抗紫外光性能测试与分析

Test and Analysis of the Anti-UV Performance of Nano-TiO_2 Glass Beads Composite Coating

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、FTIR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470～490nm，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。

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-TiO〉 These methods such as X-ray diffraction, 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 nm 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 polyacrylate 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.
