AI Technical Summary

Problems solved by technology

There are also some wear-resistant glazes on the market. Adding alumina to the glaze can also improve these properties at high temperatures, but the glaze has many pinholes and poor stain resistance.
Some experts have also studied the ultra-wear-resistant full-polish glaze. The glaze wear resistance of the glaze is also 2100 rpm level 3. Although it is a grade higher than the ordinary full-polish glaze glaze wear resistance 1500 rpm level 3, its resistance Abrasiveness is still not up to high requirements

Abstract

The invention discloses raw full-polish glaze with high abrasion resistance and a method for preparing the raw full-polish glaze. The raw full-polish glaze comprises, by weight, 28-38 parts of potassium feldspar, 4-7 parts of kaolin, 5-10 parts of sintered talc, 5-10 parts of dolomite, 16-22 parts of barium carbonate, 5-8 parts of sintered zinc oxide, 10-18 parts of fused quartz, 3-12 parts of corundum micro-powder, 1-5 parts of lithium-containing mineral and 5-10 parts of additives. The raw full-polish glaze and the method have the advantages that corundum particles and fused quartz particles are led into the raw full-polish glaze, accordingly, the availability of partial original abrasion-resistant particles can be guaranteed, large quantities of anorthite and celsian micro-crystals further can be generated, and the abrasion resistance of glaze surfaces can be improved; the lithium-containing mineral is added into the raw full-polish glaze, and accordingly liquid phases can be generated by the raw full-polish glaze at the low temperatures; lithium element ions have small radiuses, tight glass networks can be formed, and accordingly the abrasion resistance of the glaze surfaces can be improved.

Description

technical field [0001] The invention relates to the technical field of architectural ceramic glazes, in particular to a raw material high wear-resistant full polished glaze and a preparation method thereof. Background technique [0002] Full-polished glazed tile is a special glaze that can be polished after applying full-polished glazed glaze to the bottom glaze of inkjet printing and other colors. Fully polished glazed tiles combine the advantages of polished tiles and marble tiles. The glazed surface is as smooth and bright as polished tiles. Its surface glaze is characterized by transparency, no color, and does not cover the bottom glaze and various flower glazes underneath. When the glaze is polished, only a thin layer of transparent surface glaze is thrown away. The emergence of full glaze brings the tiles back to the "bright light era", thus raising the smooth, bright and magnificent effect of tile decoration to a whole new level. At present, fully glazed products ar...
