[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...
Embodiment 1
[0095] 1) Weighing: Gold tailings: 55%; Al 2 o 3 : 10%; NaO: 15%; MgO: 6%; H 3 BO 3 : 2.5%; TiO 2 : 6%; BaCO 3 : 2.5%; ZnO: 1.5%; CaO: 1.5%. Mix thoroughly and evenly, heat to 1600°C in a high-temperature furnace, and keep warm for 2 hours. Stir the glass liquid during the heat preservation process to promote the homogenization of the glass.
[0096] 2) Quenching the molten glass melted in the above 1) with water, drying, and grinding through a 200-mesh sieve to obtain glass powder. And do DSC test to get crystallization temperature results nucleation temperature 610 ℃, crystallization temperature 709 ℃, 805 ℃.
[0097] 3) Prepare the glass powder in the above 2) into a glaze, apply it on the surface of the ceramic sheet, and let it stand for 6 hours.
[0098] 4) Place the glazed ceramic sheet in the above 3) in a high-temperature furnace at 1200°C, keep it warm for 10 minutes, and rapidly cool it to below 500°C.
[0099] 5) Put the sample prepared in the above 4) into ...
