Abstract

The invention discloses coating slurry for enhancing prestress of a building ceramic. The coating slurry consists of aggregate and an adhesive in a weight ratio of 1 to 4, wherein the aggregate is a combination of oxides, hydroxides and oxygen containing salts of Si, Al, Mg, Ca and Zn; the aggregate comprises the following chemical components: 50-75% of SiO2, 10-30% of Al2O3, 0-20% of MgO, 0-25% of CaO and 0-10% of ZnO; the adhesive is one or a combination of CMC (Carboxy Methyl Cellulose Sodium), PVA (Polyvinyl Acetate), PVB (Polyvinyl Butyral) and sodium silicate. In addition, the inventionfurther discloses a preparation method and a building ceramic product of the coating slurry. The coating slurry disclosed by the invention is adopted to completely coat the surface of a building ceramic blank, by exerting prestress, the strain that the ceramic blank is stressed and broken is increased, so that the strength and the performance of the building ceramic product can be greatly improved. The preparation and the application of the coating slurry are simple in production, easy to control, low in cost and beneficial to popularization and application, and have very high practical valuesand application prospects.

Description

technical field

[0001] The invention relates to the technical field of building ceramic materials, in particular to a coating slurry for enhancing the strength of building ceramic materials, a preparation method thereof and building ceramic products. Background technique

[0002] The annual output of architectural ceramics in my country has reached 11.7 billion square meters, and the annual sales output value has exceeded 500 billion yuan. However, the architectural ceramics industry belongs to the "three high industries" of high pollution, high energy consumption, and high resource consumption. Among them, the thinning of ceramic materials is an effective means to reduce energy consumption, but after the green body is thinned, both the green body strength and the porcelain strength will decrease significantly, resulting in cracking or deformation of the product. Therefore, improving the mechanical strength of architectural ceramic products is one of the problems that need t...
