Stripping glaze, ceramic tile without glaze defects and preparation method of ceramic tile

Abstract

The invention discloses stripping glaze. The stripping glaze comprises the following raw materials in parts by weight: 8.2-10.5 parts of silicon dioxide, 6.7-8.8 parts of aluminum oxide, 3.3-5.2 partsof zinc oxide, and 2.2-3.4 parts of corundum; and the stripping glaze also comprises the following components in parts by weight: 0.6-0.8 part of calcined talc and 1.2-1.6 parts of water-washed ballclay, wherein 8.2-10.5 parts of the silicon dioxide, 6.7-8.8 parts of the aluminum oxide, 3.3-5.2 parts of the zinc oxide, 2.2-3.4 parts of the corundum, 0.6-0.8 part of the calcined talc and 1.2-1.6parts of the water-washed ball clay are spherical dry particles. According to a method disclosed by the invention, the silicon dioxide and the aluminum oxide are directly introduced, so that impurities in the raw materials of the stripping glaze are reduced; and compared with the prior art, the stripping glaze prepared by data provided by the invention has no glaze defects such as yellow edges, bubbles and pinholes during firing, at the same time, sunken parts are deeper, the stripping glaze has higher quality, so that a qualification rate of the product is improved, a defective rate is reduced, and unnecessary economic loss is avoided.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a tile with peeled glaze and no glaze defects and a preparation method thereof. Background technique [0002] Ceramic glaze is a colorless or colored glassy layer covering the surface of ceramic products. It is a product for attaching porcelain. In recent years, marble glazed tiles have become more and more popular, and more and more imitation stone glazed tiles, mainly marble and other varieties, have entered the market. Because of its better performance and texture, it is very popular among consumers. More and more consumers have changed their decoration goals from natural marble to marble-like tiles. As consumers have higher requirements for product quality, ordinary polished glazed tile products that imitate the color and texture of marble can no longer meet the needs of the market, and the demand for more three-dimensional and more realistic texture effects...

AI Technical Summary

Problems solved by technology

As consumers have higher requirements for product quality, ordinary polished glazed tile products that imitate the color and texture of marble can no longer meet the needs of the market, and the demand for more three-dimensional and more realistic texture effects of natural marble on the surface of tile products has arisen.

[0003] The invention patent of patent application publication number CN107601895A discloses a kind of peeled marble tile with peeled glaze and no glaze defect and its preparation process. It introduces too many impurities while introducing silica and alumina, which leads to When the finished product is fired in the later stage, the finished product is prone to yellow edges, bubbles and pinholes, which reduces the quality of the finished product
