Coating for improving anatase TiO2 super-hydrophilic self-cleaning ceramic glaze and application method thereof
The invention relates to a coating for improving anatase TiO2 super-hydrophilic self-cleaning ceramic glaze and an application method thereof. The coating comprises the following components in percentage by mass: 13-17 wt% of deionized water, 12-17 wt% of strong acid, 55-60 wt% of a titanium source, 5-10 % of an inducer and 6-12 wt% of absolute ethyl alcohol. According to the method, a TiO2 precursor coating containing an inducer CaTi2O5 is calcined in an oxidizing atmosphere, anatase TiO2 is promoted to be formed at low temperature, the contact angle of the glaze surface is effectively reduced, the coating is suitable for various glazes, a super-hydrophilic effect of the glaze surface is achieved, and therefore the self-cleaning performance of different ceramic glazes is improved, and the coating has a wide application range and application prospects.
本发明涉及一种应用于提高锐钛矿TiO2超亲水自清洁陶瓷釉的涂层及其应用方法，所述涂层的质量百分比组成为：去离子水13～17wt%，强酸12～17wt%，钛源55～60wt%，诱导剂5～10%，无水乙醇6～12wt%。本发明在氧化气氛下煅烧含有诱导剂CaTi2O5的TiO2前驱体涂层，促使其在低温下形成了锐钛矿TiO2，有效降低了釉面的接触角，并适应于多种釉料，实现了釉面的超亲水效果，从而提高了不同陶瓷釉的自清洁性能，因此具有广泛的使用范围和应用前景。
