Low-temperature, high-hardness and high-abrasion-resistance fully-polished glaze and preparation method thereof

Abstract

The invention discloses a low-temperature, high-hardness and high-abrasion-resistance fully-polished glaze which contains a base material and an admixture. The base material is prepared from, by weight, 15-25% of albite, 8-16% of potassium feldspar, 6-10% of kaolin, 5-8% of calcined talc, 5-10% of dolomite, 4-12% of barium carbonate, 3-5% of calcined zinc oxide, 4-20% of transparent frit, 16-28% of high-temperature frit, 5%-18% of quartz and 7-15% of alumina micro-powder, wherein the admixture is an organic silicon nano-solution or white carbon black, and the usage amount of the admixture is 15-2% by weight. In addition, the invention further discloses a preparation method of the low-temperature, high-hardness and high-abrasion-resistance fully-polished glaze and a product prepared by the same. The melting temperature is reduced through a reasonable formula system, the melting temperature range of the glaze is enlarged while energy saving and emission reduction are promoted, the hardness and abrasion resistance of the glaze surface are remarkably improved, the higher usage requirements can be very well met, and technical progress and application development of the industry of architectural ceramics are promoted.

Description

technical field [0001] The invention relates to the technical field of architectural ceramic glazes, in particular to a low-temperature, high-hardness, high-wear-resistant full-polish glaze and a preparation method thereof. Background technique [0002] High wear-resistant full polished glaze is a special glaze that can polish the glazed surface. It is applied on the surface of the antique brick. Usually the bottom glaze is matte glaze and the top glaze is transparent glaze. High wear-resistant fully polished glazed tiles combine the advantages of polished tiles and antique tiles. The top glaze is characterized by transparency, which does not cover the underlying bottom glaze and various pattern glazes. When polishing, only a thin layer of transparent top glaze is thrown away. Floor. Therefore, its glazed surface is as smooth and bright as polished bricks, and at the same time, the glazed surface is rich in patterns, thick or gorgeous in color like antique bricks. Due to i...

Problems solved by technology

However, as a new production process, high wear-resistant glazed tiles have many technical problems in terms of materials, equipment and technology, such as low glaze hardness (Vickers hardness 605.5HV0.5), not wear-resistant , suction, etc., and the high temperature fluidity is poor, prone to "water ripples"

At present, in order to solve the above problems, the current technology usually adopts the method of increasing the firing temperature of wear-resistant glazed tiles (generally 1180-1230°C) to improve the hardness and wear resistance of the glazed surface, but this method undoubtedly does not meet the requirements of the national energy-saving technology. Emission reduction standards are not conducive to the sustainable development of industrial production

For this reason, the prior art also researches and develops high-hardness super wear-resistant full-polish glaze, but the Vickers hardness of the glaze surface is only 635.5HV0.5; The Vickers hardness reaches 665.8HV0.5, although the Vickers hardness is 5-10% higher than that of ordinary full-glazed glaze, but its Vickers hardness still cannot meet the high use requirements
