| 摘 要： | 以钛酸丁酯复合醇溶胶作为前驱体,采用溶胶–凝胶法制备TiO2微粒,并将其在不同温度下焙烧,获得了纳米TiO2。在紫外光的照射下,将纳米TiO2添加到成膜物质中,配以添加剂、消泡剂等,合成了纳米复合涂料。黏度、甲醛含量、抗菌性能、耐热性以及重金属含量的测试结果表明,纳米复合涂料的各项性能均高于原涂料,尤以由600°C下焙烧所得纳米TiO2制备的涂料为佳,其黏度为14.6 Pa·s,甲醛降解率为73%,抗菌圈半径比原涂料增大了88%;在300°C下烘烤5h,涂层出现少量龟裂,但未剥落。

| Abstract: | TiO2 particles were prepared by sol-gel method with Ti(OC4H9) 4 as precursor,and then baked at different temperatures to produce nano-TiO2. Nanocomposite coatings were synthesized by adding the nano-TiO2 to film-forming materials combined with additive and foam suppressor under ultraviolet light. The test results of viscosity,formaldehyde content,antimicrobial activity,thermal stability and heavy metal contents showed that the properties of nanocomposite coatings are much better than that of the original co... |
