Thin ceramic rock slab and preparation method thereof

Abstract

The invention relates to a preparation method of a thin ceramic rock plate. The thin ceramic rock slab blank is composed of the following weight percentages: ball clay 8-12%; water-washed kaolin 17-20%; high-white kaolin 4-7%; water-milled ultra-white potassium stone powder 18-20%; water-milled albite 38% ~40%; high white alumina powder 4~5%; super white zirconium silicate 0~2%; calcined talc 3.5~7.5%; debonding agent 1~1.5%; The preparation method of the thin ceramic slab is as follows: batching of the blank → blank processing → spray drying powder making → dry pressing molding → brushing the blank to remove dust → roller printing bottom glaze → pattern decoration → pattern protective layer decoration → firing → polishing, edging .

Description

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

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
