[0071] The present invention also provides a method for preparing a superhydrophobic wear-resistant glaze coating, comprising the following steps:
[0072] A) In terms of mass fraction, 30-55% SiO 2 , 15-21% Al 2 o 3 , 10-15% NaO, 5-12% MgO, 1-5% H 3 BO 3 , 2-8% TiO 2 , 1~3% BaCO 3 , 0.5-3% of ZnO and 0.5-3% of CaO are mixed and heated to obtain molten glass;
[0073] B) water-quenching and drying the glass liquid obtained in the step A) in sequence to obtain glass powder, and preparing the glass powder into a glaze, and coating it on the surface of the ceramic substrate to obtain an intermediate coating;
[0074] C) rapid cooling after heating the intermediate coating;
[0075] D) Carry out crystallization heat treatment on the product after the rapid cooling, heat preservation at the nucleation temperature Tg for 5-20 minutes, heat preservation at the first crystallization temperature Tp1 for 10-25 minutes, heat preservation at the second crystallization temperature T...
