Glaze for ultrathin ceramic rock plate and preparation method and application of glaze

Abstract

The invention relates to glaze for an ultrathin ceramic rock plate and a preparation method and application of the glaze. The glaze comprises a cover glaze and a protective glaze, and the cover glaze is composed of a cover glaze dry material, a water-soluble organic solvent, a wetting leveling agent, a defoaming agent, an anti-settling agent and a dispersing agent in specific content; the cover glaze dry material is prepared from albite, dolomite, high bauxite, zirconium silicate and matte frit powder with specific content; the protective glaze is prepared from the protective glaze dry material, the water-soluble organic solvent, the wetting leveling agent, the defoaming agent, the anti-settling agent and the dispersing agent with specific contents; the protective glaze dry material is prepared from wollastonite, albite, kaolin, calcined talc, calcined zinc oxide, calcined aluminum oxide and bright frit powder with specific content; the dispersing agent is a self-made anhydrous polyacrylic acid dispersing agent. The glaze is suitable for a high-pressure glaze spraying process, after the glaze is sprayed to the surface of the green body of the ultrathin ceramic rock plate with the thickness of 3 mm or below through the high-pressure glaze spraying process, the strength of the green body is not affected, the defect rate of a product after firing is effectively reduced, the glazing cost is low, and the product quality is high.

Description

technical field [0001] The invention relates to the technical field of glazes, in particular to a glaze for ultra-thin ceramic rock slabs and a preparation method and application thereof. Background technique [0002] In recent years, ceramic rock slabs are widely used as home decoration materials because they can withstand cutting, drilling, grinding and other processing processes. They can be used for background walls, cabinets, wardrobes, tea sets, bathroom cabinets, sinks, doors and Kitchen cooktop panels, etc. The rock slabs used for cabinets and wardrobes are generally required to use ultra-thin ceramic rock slabs with a thickness of 3mm, and the production of 3mm ultra-thin ceramic rock slabs is still a technical difficulty that needs to be overcome urgently in China. Only a few domestic companies can Most of the production is imported from Italy. The production difficulty of this kind of slate products is that the bricks are too thin and the strength is low.

Problems solved by technology

However, the glaze used in the traditional bell jar glazing and spraying process is pure water glaze, and water easily penetrates the green body and seriously affects the strength of the green body of this type of rock slab products, resulting in easy cracking during the firing process or products in the later stage. It is easy to break during processing, so it is not suitable for glazing of this kind of slate products

However, the digital spray glazing process of digital glaze requires an expensive inkjet printer and nozzle, and compared with the traditional glazing process, the amount of glaze applied by the digital spray glazing process is limited, resulting in limited hiding power of the digital glaze, resulting in ultra-thin ceramic rock slabs The color of the product is poor, the wear resistance is poor, and the glaze is not fine enough, which leads to the poor texture of the ultra-thin ceramic rock plate product
