Abstract

The invention discloses a high strength ceramic thin plate and a preparation method thereof, and the high strength ceramic thin plate is prepared from the following components by mass: 8-12% of stone chips soil, 12-25% of potassium sand, 10-15% of sodium stone powder, 10-15% of potassium sodium stone particles, 22-27% of calcined kaolin, 3-5% of lithium feldspar and 5-10% of flaky alumina grains. The method includes the steps of (1) mixing and ball milling of all the raw materials; (2) spray pulverization; (3) 24 hours of ageing and rotting of the material prepared by the step (2), and pressing; and (4) drying and final firing. The preparation method is simple, and by adding of the flaky alumina grains, water absorption rate of the ceramic thin plate is reduced, and the breaking strength is improved.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a high-strength stoneware thin plate and a preparation method thereof. Background technique [0002] With the increase of product specifications, the thickness of general ceramic tiles is also increasing. Ceramic tiles consume more raw materials per unit area, which not only increases the load of the building, but also causes a large consumption of materials. Thin-slab bricks can save raw materials and reduce energy consumption in the preparation process, which has become the future development trend of the ceramic industry. [0003] Due to its certain water absorption, stoneware bricks are widely used in the decoration of exterior walls, kitchens, and bathroom floors. However, stoneware bricks have the disadvantages of high water absorption and poor strength, making it difficult to make large-scale thin-slab bricks, which limits their application in moder...
