Problems solved by technology

However, because the surface of the glazed tile is "glazed", the crystal content in the glaze is less, so the finished glazed tiles obtained by the existing glazed tile production process have poor wear resistance, and it is difficult to meet the requirements of the customer for laying the ground. The need for higher wear resistance

Abstract

The invention belongs to the technical field of building ceramic production and particularly relates to a glazed brick with ultrafine aluminum oxide or ultrafine aluminum hydroxide for improving glaze abrasion resistance and a preparation method of the glazed brick. A glaze of the glazed brick is prepared from, by mass, 0-10% of raw glaze, 0-100% of basic glaze formed by frits, ultrafine aluminum oxide or ultrafine aluminum hydroxide being 0.1-15% of the mass of the basic glaze, and a glaze property regulator. By adoption of existing glazing process and existing firing process of building ceramic factories, extensive raw material sources and fine composition adjustment of formulation are realized, the glaze of the fired glazed brick is smooth and flat and has high hardness and high abrasion resistance basically comparable to abrasion resistance of a polished ceramic brick, original rheological colorfulness is maintained, industrial production is benefited, and the preparation method is an important way of large-scale glazed brick production.

Description

technical field [0001] The invention belongs to the technical field of building ceramic production, and specifically relates to a polished glazed tile which introduces superfine alumina or superfine aluminum hydroxide to improve the wear resistance of the glazed surface and a preparation method thereof. Background technique [0002] Ceramic tiles have a wide range of applications in decoration, and can be widely used in walls and floors of homes or offices. According to people's aesthetic needs, they can be used for large-area laying, and can also be used for small-area decorative screens. Different applications require Different styles of products. Fully polished glazed tiles are a brand new ceramic tile product that has only appeared in recent years. The characteristic of its glaze is that the surface glaze is transparent and does not cover the underlying glaze layer and various decorative flower glazes. When the glaze is polished, only a thin layer of transparent glaze i...
