Thin ceramic rock plate and preparation method thereof

Abstract

The invention relates to a preparation method of a thin ceramic rock plate. A thin ceramic rock plate blank is composed of the following components in percentage by weight: 8-12% of ball clay; 17-20%of washed kaolin; 4-7% of high-whiteness kaolin; 18-20% of water-milled ultra-white potash stone powder; 38 to 40% of water milled albite; 4-5% of high-whiteness aluminum oxide powder; 0-2% of ultra-white zirconium silicate; 3.5%-7.5% of calcined talc; 1 to 1.5% of a dispergator; and 2-2.5% of a polymerization liquid. The preparation method of the thin ceramic rock plate comprises the following steps: preparing a green body, processing a blank, spray-drying to prepare powder, dry-pressing to form, brushing the green body to remove ash, printing ground coat on a roller, decorating patterns, decorating a pattern protective layer, firing, polishing and edging.

Description

technical field [0001] The invention belongs to the technical field of thin ceramic plates, in particular to thin ceramic rock plates and a preparation method thereof. Background technique [0002] Ceramic thin plate refers to the thickness less than 6mm, the area is greater than 1.62m 2 ceramic tiles. Compared with similar products, the unit area of ​​ceramic thin plates is more than double that of conventional building ceramic materials, which can save more than 60% of raw material resources and reduce overall energy consumption by more than 50%, whether it is the amount of raw materials used or the energy used in the production process The low-carbon goal of "material saving and energy saving" has been well achieved; at the same time, the light weight of thin-plate ceramics not only saves logistics and transportation costs, but also reduces the load of buildings. However, due to the thin ceramic sheet and its large area, problems such as low strength and poor toughness ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is aimed at the thin ceramic slabs with a thickness of less than 6mm (especially a thickness of 3mm), which are prone to excessive water absorption or uneven water absorption of the green body after water glaze decoration in the production process, and the green body is easy to crack when it is dry. The billet has low strength and poor toughness of the finished product, and it is easy to cause deformation and damage of the thin plate during green body preparation, transfer, and sintering. It provides a thin ceramic rock plate that is free from drying and bisque firing, and does not touch water during the production process. The preparation method ensures that the product will not dry and crack due to excessive water absorption or uneven water absorption
