Problems solved by technology

This is superior to metal products such as copper, iron, aluminum, etc. Under long-term use of daily-use porcelain, oxidation reactions will occur on the surface of the porcelain, making the surface of the porcelain dark and affecting the viewing of the porcelain. Limited, it will cause pinholes on the surface of the porcelain, which will cause a lot of dirt to be absorbed on the surface of the porcelain

Abstract

The invention discloses high-temperature-resistant oxidation-resistance ceramic glaze and a preparation method thereof and relates to the technical field of manufacture of ceramic glaze. The high-temperature-resistant oxidation-resistance ceramic glaze comprises nano alumina, nano silica, nano boron nitride powder, nano boron carbide powder, zinc oxide, kaolin, calcined talc, sodium oxide, a surfactant, glass fiber, nano titanium dioxide, zinc nitrate, and yttrium nitrate. The preparation method comprises the steps of (1) preparing an antibacterial agent; (2) preparing a high-temperature-resistant oxidation-resistant base; (3) preparing mixed glaze slurry; (4) preparing final glaze. The high-temperature-resistant oxidation-resistant base enables daily ceramics to be less prone to oxidation and maintains the glossy surface of ceramics; by changing the ratio of the original glaze and adding the calcined talc and zinc oxide, expansion coefficient of the glaze slurry can be decreased, the surface elasticity of the glaze can be improved, the mobility of the glaze slurry can be improved, and chances for the glaze surface to generate the defects of pinholes and crinkle are slimmed.

Description

technical field [0001] The invention relates to the technical field of ceramic glaze production, in particular to a high-temperature-resistant and anti-oxidation ceramic glaze and a preparation method thereof. Background technique [0002] Daily-use porcelain has been loved and used by the masses of the people for a long time because it has the following advantages: First, it is easy to wash and keep clean. The surface of daily-use porcelain glaze is bright and delicate, and it is easy to wash off after being stained. Second, the thermal stability is better and the heat transfer is slow. The daily meal has the property that it is not easy to burst when it is subjected to sudden heat and sudden cold changes of a certain temperature difference. In this regard, it is superior to glassware, which is a poor conductor of heat and conducts heat slowly. It is used to hold boiling water or scalding hot food, and it is not too hot to handle. Third, the chemical properties are stab...
