Problems solved by technology

[0002] With the gradual improvement of people's living standards, tiles are more and more popular as building and decoration materials. The preparation of tiles is through grinding, mixing, pressing, glazing and sintering. Glazing on the surface of tiles can increase the strength and smoothness of tiles. , reduce the water absorption rate of tiles, and make the tiles easy to clean, but there are many brands of tiles on the market at present, and the quality is uneven. The surface is raised first and then falls off, which seriously affects the decorative effect of the tiles
[0003] The existing patent document CN 107226619 A discloses an acid-resistant diamond glaze and its preparation method, and a preparation method of acid-resistant diamond glaze ceramic tiles. The prepared glaze can prevent glaze shrinkage and cracking, but the glaze only has good acid resistance and is not suitable for Corrosive alkaline stains do not have strong tolerance, which will easily corrode the surface of the tiles and shorten the service life of the tiles

Abstract

The invention mainly relates to the technical field of ceramic glaze processing and discloses corrosion-resistant environment-friendly glaze for tiles. The glaze is prepared from, by weight, 37-39 parts of silicon dioxide, 26-28 parts of barite, 24-26 parts of barium feldspar, 17-19 parts of pyrophyllite, 14-16 parts of kaolinite, 5.2-5.6 parts of tin oxide, 4.5-4.9 parts of niobium pentoxide, 4.1-4.5 parts of tungsten oxide, 3.4-3.8 parts of cerium oxide, 2.3-2.7 parts of cobalt oxide and 0.3-0.5 part of graphene. The glaze can eliminate pinholes and bubbles, thereby avoiding glaze shrinkage,enabling the surfaces of the tiles to be exquisite and bright and having high resistance to acid and alkali corrosion, and after glazing, sintering is low in temperature and short in time, energy issaved, and environment is protected; cobalt oxide is added for calcining modification after pyrophyllite is smashed, so that hardness and glossiness of pyrophyllite powder are improved, the surfaces of the tiles are made smooth and exquisite, and corrosion resistance is enhanced.
