Slag-doped high-intensity ceramic floor tile

Abstract

The invention discloses a slag-doped high-intensity ceramic floor tile, which comprises the following raw materials by weight part: 4-6 parts of meerschaum, 6-10 parts of perlite, 30-50 parts of converter slag, 20-25 parts of powdered steatile, 5-10 parts of kaolin, 15-25 parts of waste glass micro powder, 1-2 parts of hydroxyethyl methyl cellulose, 2-4 parts of water glass powder, 2-4 parts of zinc oxide, 5-8 parts of brown sugar, 0.1-0.3 parts of polyvinylpyrrolidone and a proper amount of distilled water. The floor tile has the advantages of high hardness, high mechanical strength, good heat stability and ageing resistance, little pollution, and wide application scope.

Description

technical field [0001] The invention relates to the field of manufacturing ceramic floor tiles, in particular to a high-strength ceramic floor tile doped with steel slag and a preparation method thereof. Background technique [0002] my country is a big country of iron and steel, and about 150 kilograms of steel slag is produced for every ton of steel produced. Steel slag stacked in the slag yard occupies a large amount of land and pollutes the environment. For steel slag containing trivalent chromium, it will transform into hexavalent state after being placed in the open air for a long time, which will cause great harm to the ecological environment and the growth of animals and plants. Steel slag mainly contains calcium oxide, silicon dioxide, aluminum oxide, iron oxide, manganese oxide and carbon sulfide, and has potential gelling activity and broad application prospects. At present, it is of great social significance to study how to efficiently utilize steel slag to prod...

Problems solved by technology

Traditional ceramic tiles use high-quality kaolin, feldspar, clay, etc. as the main raw materials, and are prepared by wet pulverization and spray drying processes. However, this preparation method has high energy consumption and produces a large amount of water vapor, nitrogen oxides, and sulfur oxides Heavy pollutants such as waste and dust pollute the tail gas, which seriously pollutes the environment and seriously deviates from the requirements of clean production in the ceramic industry, and more and more kaolin is used in papermaking, coatings, fertilizers, refractory materials, rubber, plastics, petrochemicals and other industries. The raw materials for the ceramic tile industry are very scarce
