Problems solved by technology

Compared with porcelain sanitary ceramics, the deformation of ceramic sanitary ceramics has been improved, but the strength is not enough, which limits its use
In addition, Fujian is rich in ceramics and minerals, and a large amount of blast furnace slag and ceramic waste powder will be produced in the production process. These waste materials are difficult to digest in the natural environment, and improper treatment will cause serious environmental problems. It is very important to improve the green body formulation of the deformation degree of sanitary ceramics while recycling waste materials

Abstract

The invention relates to a ceramic sanitary ceramic green body and a preparation method thereof, and belongs to the technical field of ceramic preparation. The preparation raw materials of the ceramicsanitary ceramic green body comprise a green body material and an auxiliary agent, wherein the green body material comprises, by weight, 10%-30% of a southern black mud, 5%-10% of a southern kaolin,8%-14% of a waste ceramic powder, 5%-12% of a blast furnace slag, 10%-20% of a southern pyrophyllite, 1%-5% of talc, 5%-10% of calcined kaolin, 1%-5% of dolomite, 15%-20% of quartz and 4%-6% of wollastonite; and the auxiliary agent is boron nitride micro-powder, and the usage amount of the auxiliary agent is 0.1%-0.5% of the green body material mass. The blast furnace slag and the ceramic waste powder are introduced as raw materials of the ceramic green body, southern raw materials are added, and boron nitride micro-powder is added as the firing auxiliary agent, so that the blast furnace slagand the ceramic waste powder can be subjected to resource utilization, and firing flexural strength of a product can be improved.

Description

Technical field [0001] The present invention relates to the field of ceramic preparation, and more relates to a ceramic bathroom blank and a preparation method thereof. Background technique [0002] According to national standard GB6952-2015, water absorption rate E ≤ 0.5% is porcelain hygiene ceramics, water absorption rate of 0.5% <E ≤ 15.0% is 炻 陶 卫 卫, 炻 炻 卫, 炻, 炻, 炻, ceramics. According to national standard GB6952-2005, water absorption is 8.0% <E ≤ 15.0% is ceramic. [0003] Compared with the general ceramic products, the sanitary ceramics have a large size, the difficulty of its burning is that the larger the size of the firing, the more deformation of the firing, the cause of the deformation is, in the high temperature firing, the glass phase produced in the ceramic branch Quickly soften, the product produces bending deformation under gravity. Compared to porcelain hygiene ceramics, the deformation of ceramic ceramics is improved, but the strength is not enough, whic...
