Problems solved by technology

[0004] In the prior art, in order to improve the hardness and wear resistance of the porcelain stoneware glaze, it is often considered to add α-Al to the dry grain formula 2 o 3 Nano powder or α-Al 2 o 3 Micro-powder, mixed by mechanical stirring, glazed by glaze dipping, oil spraying or pouring glaze, etc. After drying, it is fired at high temperature to improve the hardness and wear resistance of the glazed surface of porcelain stone slabs without affecting the original The gloss and color of ceramic rock slab glaze, in practice, although α-Al 2 o 3 Nano powder can significantly improve the hardness and wear resistance of ceramic rock slab glaze, but when the amount of nano powder added is too large, the hardness and wear resistance of porcelain rock slab glaze are not further improved

Abstract

The invention discloses a dry granule, dry granule glaze, high-hardness and high-wear-resistance rock plate and a preparation method thereof, and belongs to the technical field of building rock plates, the dry granule, dry granule glaze, high-hardness and high-wear-resistance rock plate comprises the following raw materials by mass: 20-35% of potassium feldspar, 10-35% of quartz, 10-25% of calcite, 5-15% of barium carbonate, 5-20% of zinc oxide, 1-2% of alpha-Al2O3 nano powder, 6-15% of nano silica, and 15-20% of chitosan, the finally prepared high-hardness and high-wear-resistance ceramic rock plate glaze surface is high in hardness and wear-resistant, the Mohs hardness is more than level 5, the wear resistance is more than level 4, and the production cost is low; the preparation method of the high-hardness and high-wear-resistance rock plate provided by the invention is simple and convenient in steps and suitable for industrial large-scale preparation, and the sintering temperature is reduced by 300-500 DEG C compared with the sintering temperature of the existing high-hardness and high-wear-resistance rock plate.

Description

technical field [0001] The invention relates to the technical field of ceramic slate, in particular to a slate with dry grain, dry grain glaze, high hardness and high wear resistance and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the choice of decoration and decoration materials is becoming more and more personalized, and more emphasis is placed on style and taste. The demand for applications in decoration is also increasing. In recent years, ceramic slabs have been gradually applied to the field of decoration. They have the advantages of excellent acid and alkali resistance, high hardness, and high temperature resistance. Therefore, they have extremely broad application prospects. Ceramic slate is made of natural raw materials through a special process, pressed by a press of more than 10,000 tons, combined with advanced production technology, and fired at a high temperature of more than 1200 ° C, which can...
