Abstract

The invention discloses a strong-base corrosion-resistant ceramic glaze. The ceramic glaze comprises the following components: a boron frit, quartz powder, spodumene, calcined zinc oxide, calcined talcum powder, kaolin, zirconium silicate, a toner and the like. The preparation method comprises the following steps: preparing materials according to mass parts of the components, carrying out ball milling to obtain glaze, sieving the glaze discharged out of a ball mill to obtain glaze slurry, adding water and an electrolyte to respectively adjust the concentration and thixotropy of the glaze slurry, dipping a glaze blank in the glaze slurry, carrying out drying, then putting the glaze blank into a roller kiln, and carrying out firing at a temperature of 1210-1240 DEG C to obtain a high-densityborosilicate glass body. Various pigments are wrapped in the glass body for protection, the firing temperature is low, compactness of the fired glaze is guaranteed, a complete glaze glass body with high density, high gloss and pore-free glaze surface is achieved, and Si-O bonds formed in the glaze glass are protected from being damaged, so that corrosion of strong bases can be resisted.

Description

technical field [0001] The invention belongs to the field of ceramic glazes of inorganic non-metallic materials, and in particular relates to a ceramic glaze resistant to strong alkali corrosion and a preparation method thereof. Background technique [0002] The development of ceramics has a long history and glorious achievements. The process of evolution from pottery to porcelain has enriched the connotation, diversity and practicability of ceramics. It occupies an extremely important position in the history of Chinese culture and craft development. In modern life, people rely more and more on ceramics, and the requirements for ceramic performance are getting higher and higher. Glaze is a thin glassy layer covering the surface of ceramics and enamel. It has been widely used in the preparation of ceramics, enamel and other products. It has a long history and is used in various fields. [0003] In the 21st century, mechanized dishwashers are generally used for cleaning ename...
