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 f...

Embodiment Construction

[0055] The present invention will be described in further detail below in conjunction with embodiment:

[0056] The thin ceramic rock slab, the thin ceramic rock slab blank consists of the following weight percentages:

[0057]

[0058] Among them: the aluminum content of spherical clay is 39%, the iron content is 0.1%, the aluminum content of washed kaolin is 41%, and the iron content is 0.05%; the specific surface area of ​​high white kaolin is 28m 2 / g, particle size distribution D9019.2μm, whiteness 85°, LAB value: L: 94.8, A: 1.1, B: 5.6; water-milled ultra-white potassium stone powder iron content 0.1%, water-milled albite iron content 0.08%; The aluminum content of high-white alumina powder is 99.33%, the iron content is 0.03%, and the particle size distribution is D9010.8μm; the debonding agent is a mixture of sodium tripolyphosphate, sodium hexametaphosphate, sodium humate, and sodium polyacrylate; The polymerization liquid is a mixed liquid of modified lignin, po...

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 ...
