Embodiment Construction

[0022] An embodiment of the present invention is a method for preparing a toughened architectural ceramic product, which is prepared from architectural ceramic green body powder and low-shrinkage material powder. The building ceramic body used adopts the formula of building ceramic porcelain body, and its raw materials are composed of 30 parts of kaolin, 20 parts of quartz, 35 parts of feldspar, 5 parts of talc and 10 parts of medium temperature sand in parts by weight. The steps of the above-mentioned preparation method are as follows:

[0023] (1) Preparation of low shrinkage material powder

[0024] The low-shrinkage material is one of the following materials or a combination thereof, or a combination with porcelain powder: SiO 2 Main minerals or rocks, wollastonite, diopside, cordierite, tremolite, pyrophyllite, andalusite, sillimanite; porcelain powder is the powder after the above-mentioned building ceramic body is sintered into porcelain; the above-mentioned After the...

Abstract

The invention discloses a preparation method of a toughened building ceramic product. The preparation method comprises the following steps: laying low-shrinkage material powder on the surface of a building ceramic green body, carrying out dry pressing, and sintering. In addition, the invention also discloses a ceramic product prepared by the preparation method of the toughtened building ceramic product. The shrinkage of the ceramic body is counteracted by the low-shrinkage material so that the shrinkage of the surface layer of the ceramic is less than that of the base body in the shrinkage process, the ceramic is dragged by the shrinkage of the base body to form surface layer pressure stress, and the aim of remarkably improving the breaking strength of the ceramic product is further achieved; meanwhile, the preparation of the building ceramic thin plate is also facilitated so that the use amount of raw materials for producing green bodies can be reduced, high-quality ceramic raw material resources are saved, the production cost is reduced, and energy conservation and emission reduction are facilitated, thereby playing an important role in sustainable development of the building ceramic industry, acceleration of ecological civilization construction and realization of green development.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a preparation method of a toughened architectural ceramic product and the ceramic product. Background technique [0002] Tempered glass (also known as prestressed glass) refers to ordinary glass that undergoes a certain treatment method to form a compressive stress on the glass surface to effectively prevent the expansion of micro-cracks on the surface, and partially or completely offset the surface tensile stress caused by the external load, thereby improving the glass. Mechanical strength, stability and safety. At present, the formation of compressive stress on the surface of glass tempering includes physical tempering and chemical tempering. Physically tempered glass was first proposed by the Frenchman De la Basti in 1874. Specifically, ordinary glass was heated to the softening temperature (650-800°C) to rapidly cool it under a cooling medium (gas, liquid, etc.). ...
