Abstract

The invention discloses a graphene ceramic product and a preparation method of the graphene ceramic product. Raw materials of the ceramic product comprises, by weight, 0.2-0.5 part of graphene, 75.5-80.8 parts of argil and 15 parts of zirconium oxide. The preparation method comprises the steps that the raw materials are mixed in proportion and injected into a ball mill, water is added to the raw materials, and then powder grinding is conducted; ground slurry is subjected to sedimentation; after sedimentation, supernatant liquid is pumped out, sediment is taken out, placed on the clean ground and dried in the sun; the dried clay is placed into a pugmill for clay smelting, and air in the clay is removed; the smelted clay is made into a green body, and the green body is dried in a drying room at the temperature ranging from 30 DEG C to 40 DEG C; the dried green body is burned into a ceramic green body, the ceramic green body naturally cools, and then the graphene ceramic product is obtained. According to the graphene ceramic product and the preparation method of the graphene ceramic product, on the condition that other properties of ceramic remain unaffected, the strength and wear resisting performance of the green body are improved, so the prepared ceramic product has excellent hardness and strength, is large in tensile strength and has great practical value.

Description

technical field [0001] The invention provides a graphene ceramic product and a preparation method thereof, belonging to the technical field of ceramics. Background technique [0002] Ceramics have a long history of use in our country, and are now widely used all over the world. Daily-use ceramics have become an indispensable part of people's daily life. All kinds of tableware, tea sets, and various sanitary ware can be seen everywhere. These ceramics It is not only beautiful and generous, but also has the advantages of easy cleaning, temperature resistance, wear resistance and corrosion resistance, etc., and is deeply loved by consumers. However, ceramic products are generally brittle, not resistant to impact, poor toughness, uneven glaze color and easy to fall off. , high production energy consumption and other shortcomings, resulting in serious damage in the process of production, transportation and application, thereby increasing production costs, so it is urgent to impro...
