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 invention relates to the technical field of ceramic preparation, and relates to a ceramic sanitary ceramic body and a preparation method thereof. Background technique [0002] According to the national standard GB6952-2015, the water absorption rate E≤0.5% is porcelain sanitary ceramics, and the water absorption rate 0.5%<E≤15.0% is stoneware sanitary ceramics. Stoneware sanitary ceramics and ceramic sanitary ceramics are collectively referred to as stoneware sanitary ceramics. ceramics. According to the national standard GB6952-2005, the water absorption rate of 8.0%<E≤15.0% is ceramic sanitary ceramics. [0003] Compared with general ceramic products, the size of sanitary ceramics is larger, and the difficulty of firing is that the larger the size, the easier it is to deform during firing. The reason for the deformation is that the glass phase produced in the ceramic body during high-temperature firing Softens rapidly, and the product ben...
