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

A kind of Graphene ceramic and preparation method thereof
Technical field
The invention provides a kind of Graphene ceramic and preparation method thereof, belong to ceramic technology field.
Background technology
Pottery has long use history in China, nowadays widely use in worldwide, domestic ceramics has just like become a part indispensable in people's daily life, panoramic tableware, tea set, all kinds of sanitary equipment etc. are seen everywhere, these potteries are not only elegant in appearance, various shapes, also there is easy cleaning simultaneously, heatproof, the advantages such as wear resistant corrosion resistant, be well received by consumers, but ceramic product universal existence is crisp, not shock-resistant, poor toughness, glaze colours inequality easily comes off, the shortcomings such as production energy consumption is large, cause its breakage in production and transport and application process more serious, thus increase production cost, therefore in the urgent need to improving its performance, promote domestic ceramics industry to low cost, environmental protection future development.
Summary of the invention
To be solved by this invention is the problem that existing ceramics strength is low.
In order to solve the problem, the invention provides a kind of Graphene ceramic, it is characterized in that, raw material comprises Graphene 0.2 ~ 0.5 weight part with weight parts, potter's clay 75.5 ~ 80.8 weight part and zirconium white 15 weight part.
Present invention also offers the preparation method of above-mentioned Graphene ceramic, it is characterized in that, comprise following concrete steps:
Step 1): raw material is mixed in proportion rear injection ball mill, carries out grinding after adding water, the material-mud fineness requiring grinding to go out is 500 orders;
Step 2): the material-mud of milled is precipitated; Extract supernatant liquid out after precipitation, and taken out by throw out and be placed on clean ground and dry, the time of drying is 40 ~ 50 days;
Step 3): the earth after drying is put into soil kneader and carries out mud refining, get rid of the air in mud simultaneously;
Step 4): the mud refined is made base substrate, and dries in the baking room of 30 ~ 40 DEG C;
Step 5): the base substrate after drying is fired into ceramic body, and calcine 4 ~ 12 hours at 1200 ~ 2000 DEG C, naturally cooling obtains Graphene ceramic.
The invention has the advantages that, in the impregnable situation of maintenance other performances of pottery, improve intensity and the abrasion resistance properties of base substrate, make the ceramic prepared have excellent hardness and intensity, tensile strength is large, has practical value.
