Graphene anti-cracking glaze water and preparation method thereof

Abstract

The invention provides graphene anti-cracking glaze water and a preparation method thereof. The preparation method comprises the steps of blending, grinding, regulation of the content of iron oxide, preparation of graphene dispersion liquid, mixing, regulation of expansion factors, and stirring and uniformly mixing to obtain a finished product. Graphene is added in the graphene anti-cracking glazewater, thus, the strength of toughness of the glaze water can be improved effectively, an anti-cracking property can be greatly improved, addition of the graphene cannot affect the characters and color of the glaze water, and the quality of a ceramic finished product can be improved. The graphene dispersion liquid is prepared by a polymeric dispersant, and the dispersion stability of graphene inthe glaze water can be improved effectively.

Description

technical field [0001] The invention belongs to the technical field of glaze water preparation, and in particular relates to a graphene anti-crack glaze water and a preparation method thereof. Background technique [0002] Glaze is a colorless or colored glassy thin layer covering the surface of ceramic products. It is made of mineral raw materials (feldspar, quartz, talc, kaolin, etc.) and raw materials in a certain proportion (some raw materials can be made into frit first) Grind to make glaze slurry, apply it on the surface of the green body, and calcined at a certain temperature, which can increase the mechanical strength, thermal stability and dielectric strength of the product, as well as beautify the utensils, facilitate cleaning, and not be corroded by dust and filth, etc. However, except for the different colors, the glazes on the market now have similar functions and poor crack resistance, which makes ceramic products easy to crack. Graphene is a hexagonal structur...

[0002] Glaze is a colorless or colored glassy thin layer covering the surface of ceramic products. It is made of mineral raw materials (feldspar, quartz, talc, kaolin, etc.) and raw materials in a certain proportion (some raw materials can be made into frit first) Grind to make glaze slurry, apply it on the surface of the green body, and calcined at a certain temperature, which can increase the mechanical strength, thermal stability and dielectric strength of the product, as well as beautify the utensils, facilitate cleaning, and not be corroded by dust and filth, etc. However, except for the different colors, the glazes on the market now have similar functions and poor crack resistance, which makes ceramic products easy to crack. Graphene is a hexagonal structure composed of carbon atoms with sp² hybrid orbitals Graphene is a two-dimensional carbon nanomaterial with a honeycomb lattice and has excellent optical, electrical, and mechanical properties. If graphene can be added to the glaze water, it can increase the anti-crack performance of the glaze water without affecting the characteristics of the glaze water itself. Therefore, the present invention proposes a kind of graphene anti-crack glaze water and preparation method thereof
