Abstract

The invention relates to an architectural ceramic supply, particularly a high-heat-conductivity functional ceramic sheet and a preparation method thereof. The high-heat-conductivity functional ceramic sheet is prepared from the following raw materials in percentage by weight: 5-10% of quartz, 50-60% of bauxite, 1-5% of aluminum oxide, 5-10% of kaolin, 5-15% of feldspar, 1-5% of talcum, 5-10% of industrial waste and 6-10% of nucleating agent. The preparation method comprises the following steps: mixing the raw materials with water, carrying out ball milling to obtain a slurry, screening to remove iron, carrying out spray granulation on the slurry through a drying tower to obtain powder, compacting to obtain a ceramic sheet green compact, drying the green compact, calcining, and cooling to obtain the high-heat-conductivity functional ceramic sheet. The thickness is 3-5mm and is only 1 / 3-1 / 4 of the thickness of a common ceramic tile; the method reduces the raw material consumption, lowers the firing temperature, shortens the firing time, saves the resources and energy, and reduces the discharge of sewage and waste; and the high-heat-conductivity functional ceramic sheet has the advantages of wear resistance, light weight, high strength, elegant appearance and the like, and greatly enhances the heat efficiency of floor heating when being applied to floor heating, thereby reducing the energy consumption.

Description

technical field [0001] The invention relates to a building ceramic product, in particular to a thin ceramic plate with high thermal conductivity and a preparation method thereof. Background technique [0002] With the rapid development of the economy, the architectural ceramics industry has also risen rapidly, playing a role that cannot be ignored in the national economy. However, as a high-energy-consumption and polluting industry, the architectural ceramics industry has problems such as development and excessive consumption of resources and energy, which seriously restricts the rapid and sustainable development of the architectural ceramics industry. Therefore, ceramic thinning, functionalization, and reduced production are important ways for the building ceramics industry to achieve resource conservation, energy conservation and emission reduction. [0003] Liu Ximin ("Ceramics" 2009 (9) 20-21) discussed the application prospects of ceramic thin plates from the aspects o...
