Problems solved by technology

[0003] In actual production, the rationality of the green body formula and product surface decoration technology plays a key role in whether the ceramic slab can adapt to actual production. Unreasonable design of any link may lead to insufficient strength of the ceramic slab and shrinkage of firing. Excessive rate, uneven density, poor thermal stability, etc.

Abstract

The invention discloses an ultra-thick rock plate and a preparation method and application thereof. The ultra-thick rock plate comprises a green body layer and a glaze layer, the green body layer comprises bentonite, kaolin, porcelain sand, sand powder, aluminum powder, wollastonite, feldspar and green body additives, and the green body additives comprise phosphate, humate, silicate and cellulose salt. The mass ratio of the bentonite to the kaolin is (1-2.5): (1-2). The bentonite is adopted to replace part of kaolin, so that the ignition loss is reduced, and the oxidation performance and hardness are improved. Phosphate, humate, silicate and cellulose salt are adopted as green body additives, the defect that the strength of the green body is reduced due to reduction of kaolin is overcome, and the product performance and the technological requirements of the production process are better met.

Description

Technical field [0001] The present invention belongs to the technical field of ceramic decorative materials, and in particular to a super thick rock plate and a preparation method thereof. Background technique [0002] There are many varieties of ceramic products, rich in color, good decoration, easy to maintain, and colorful product color is very realistic, and favored by consumers. Among them, the large-scale porcelain bricks are widely used in the decorative walls due to the economic, beautiful and color variety. Because of its own characteristics such as the thickness of the brick body, large-scale porcelain bricks, especially the thickness of 3,200, a thickness of 20 mm, and thickness of 20 mm, thickness, thickness With the thickness of natural marble, it is very good to replace natural marble for home renovation, but since this product has good thermal stability, replace quartz stone for kitchen countertops, so the prospect is broad. [0003] In actual production, the ratio...
