Wear-resistant color-assisting frit for wear-resistant glaze, super wear-resistant glaze and ceramic tile preparation method

Abstract

The invention relates to the technical field of architectural ceramics, and discloses a wear-resistant color-assisting frit for wear-resistant glaze, super wear-resistant glaze and a ceramic tile preparation method. The wear-resistant color-assisting frit comprises the following raw materials: potassium feldspar, albite, quartz powder, calcined kaolin, alumina powder, calcite, calcined talc, zinc oxide, barium carbonate, strontium carbonate, calcium fluoride and boric acid. The raw materials of the super wear-resistant glaze comprise raw glaze and wear-resistant color-assisting frits. According to the wear-resistant color-assisting frit for the wear-resistant glaze, the glaze layer transparency and the color development effect of the wear-resistant glaze can be improved, so that the wear-resistant glaze can be applied in a relatively large thickness; according to the super wear-resistant glaze and the preparation method thereof, the silica-alumina ratio of the glaze is controlled within the range of 4-6, so that the glaze surface has certain gloss, and the texture of the glaze surface and the antifouling effect after polishing are ensured; the performance of the glaze slip is adjusted by glue, so that the glaze slip is conveniently applied in a bell-jar glaze spraying manner; according to the preparation method of the brick, the ultra-wear-resistant glaze is applied in a bell jar glaze spraying mode, the glaze surface after firing is good in light transmission and color development effect, and very high wear resistance is achieved.

Description

technical field [0001] The invention relates to the technical field of building ceramics, in particular to a wear-resistant color-aided frit used for wear-resistant glaze, a super wear-resistant glaze and a method for preparing ceramic tiles. Background technique [0002] The wear resistance and hardness of the ceramic tile glaze determine the service life of the ceramic tile. The wear resistance level of ordinary polished glazed tiles is 750 to 1500 rpm, the wear resistance level is 3, and the Mohs hardness is 3 to 4. The super wear-resistant glaze is generally low in silicon and aluminum, with less silicon and more aluminum. According to the traditional glaze polishing process, the color and permeability are poor, the pores after polishing are many, the glaze gloss is low, and the antifouling effect is not good. Currently on the market The super wear-resistant glazes are produced by screen printing, and the glaze layer is as thin as possible. For example, as disclosed in ...

AI Technical Summary

Problems solved by technology

[0003] At present, cloth wear-resistant glaze generally uses 80 or 100 mesh to thicken the stencil three times and print it twice. The glaze layer is too thin. After polishing, the glaze surface is easy to miss and throw, forming defects such as pitting, snowflakes, throwing through, and yellow edges. By increasing the number of printings, the color and transparency of the glaze will become worse, the pores will be more, the antifouling ability will decrease, and the sense of layering will decrease.

And with the popularity of large-size ceramic tiles and rock slabs, there is still no large-scale printing machine for applying wear-resistant glaze on the market, and the printing process cannot meet the production requirements
