preparation example Construction

[0062] Correspondingly, the present invention also discloses a method for preparing a building ceramic plate / brick, comprising:

[0063] (1) add the base material and additive of described building ceramic board / brick by proportioning, carry out ball milling mixing with water as medium to obtain mud;

[0064] (2) spray drying the mud into powder with a water content of 4-9 wt%;

[0065] (3) pressing and molding the powder with a press, and obtaining a green body after drying;

[0066] Under normal circumstances, dry powder pressing has lower requirements on the plasticity of the blank, so that it can be matched with the formula of the present invention and less alumina is introduced to reduce the sintering temperature. On the contrary, plastic molding has high plasticity to the blank, and a large amount of kaolin, mud and other plastic raw materials with high alumina content must be added to the blank, resulting in a high sintering temperature.

[0067] (4) After glazing is ...

Abstract

The invention discloses a building ceramic plate / brick, which is prepared from a base material and an additive, wherein the base material comprises 5-25 wt% of a plastic raw material, 40-60 wt% of a fluxing raw material, and 25-45 wt% of wollastonite and / or wollastonite fiber, and relative to the base material, the addition amount of the additive is 0.01-6 wt%, and the additive comprises one or a combination of an organic reinforcing agent and a water reducing agent. Correspondingly, the invention also discloses a preparation method of the building ceramic plate / brick. According to the invention, through formula design, wollastonite and / or wollastonite fibers are introduced into a green body for reinforcement and toughening while low-temperature fluxing raw materials are introduced to realize low-temperature firing and avoid high-temperature melting failure of inorganic fibers, so that the product performance is remarkably improved, and the energy consumption and the production cost are reduced.

Description

technical field [0001] The invention relates to the technical field of building ceramic materials, in particular to a building ceramic plate / brick suitable for ceramic tiles and decorative panels of household, furniture and cabinets and a manufacturing method thereof. Background technique [0002] In the past two years, architectural ceramic tiles are accelerating the transformation and development in the direction of ceramic plates, and architectural ceramics are gradually opening up the market in the fields of stone, home furnishing, furniture, and cabinet decorative panels. In 2020, more than 80 ceramic enterprises across the country have added 112 ceramic slate production lines. However, at present, the application of ceramic plates as home furnishing, furniture, and cabinet decorative panels generally has the problems of processing and cutting and high energy consumption. These two problems seriously restrict the development of the industry. The sintering temperature o...
