摘　　要：利用多功能分散机制备纳米TiO_(2)光触媒纳米涂料,对涂料的常规性能及涂料的耐擦洗、耐碱性能进行了研究.采用响应面试验设计方法,分别以纳米TiO_(2)含量、涂覆厚度和光照强度为因子,优化工艺条件.结果表明,TiO_(2)含量对涂料的耐碱性没有影响,在TiO_(2)含量为8%时,耐擦洗度最大;涂料净化甲醛的最佳工艺条件为:纳米TiO_(2)含量为10.3%,涂覆厚度为250μm,光照强度为40 mW·cm^(-2).This research prepared the nano-TiO_(2) photocatalyst nano-coatings by multifunctional dispersion machine,and studied the conventional properties,scrub resistance and alkali resistance of the coatings.The experiment used the response surface methodology to optimize the processing conditions with nano-TiO_(2) content,coating thickness and light intensity as factors.The results show that the content of TiO_(2) has no effect on the alkali resistance of the coating,and the scrub resistance is the highest when the content of TiO_(2) is 8%.The result also shows that the optimum conditions of formaldehyde purification by coating are as follows:the content of nano-TiO_(2) is 10.3%,the coating thickness is 250μm,and the light intensity is 40 mW·cm^(-2).
