A kind of glaze for ultra-thin ceramic rock plate and its preparation method and application

Abstract

The invention relates to a glaze for ultra-thin ceramic rock slabs, a preparation method and application thereof. The glaze includes surface glaze and protective glaze. The surface glaze is composed of specific content of surface glaze dry material, water-soluble organic solvent, wetting and leveling agent, defoamer, anti-settling agent and dispersant; surface glaze dry material is composed of specific content Albite, dolomite, high alumina bauxite, zirconium silicate and matte frit powder; the protective glaze is composed of a specific content of protective glaze dry material, water-soluble organic solvent, wetting and leveling agent, defoamer, It is composed of anti-settling agent and dispersant; the protective glaze dry material is composed of specific content of wollastonite, albite, kaolin, burnt talc, calcined zinc oxide, calcined alumina and bright frit powder; the dispersant is self-made anhydrous poly Acrylic dispersant. The glaze is suitable for the high-pressure spray glaze process, and after being sprayed on the surface of the ultra-thin ceramic rock slab with a thickness of 3mm or less by the high-pressure spray process, it will not affect the strength of the body, effectively reducing the defect rate of the product after firing, and Low glazing cost and high product quality.

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
