Description

A kind ofly add the floor tile that slag has thermal insulation function

Technical field

The present invention relates to floor tile and manufacture field, be specifically related to a kind ofly add slag floor tile with thermal insulation function and preparation method thereof.

Background technology

China is big steel country, often produces the slag that 1 ton of steel will produce about 150 kilograms.Slag is deposited in slag field and occupies a large amount of soil and pollute environment, for containing the slag of three valence state chromium, outdoor be long placed in after change hexavalent state into, very large harm is produced to ecotope and animal and plant growth.Main containing compositions such as calcium oxide, silicon-dioxide, aluminum oxide, ferric oxide, manganese oxide and nitric sulfids in slag, there is potential gelation activity and application prospect widely.How efficiency utilization slag produces high value added product in current research, and save energy and Sustainable development industry have important social effect.

Along with the raising of people's living standard, demand and the output of architectural pottery are growing.Traditional ceramic tile with high grade kaolinite, feldspar, clay etc. for main raw material, adopt the preparation of wet powder-making, drying process with atomizing method, but it is large to there is energy consumption in this preparation method, produce a large amount of containing heavily contaminated tail gas such as water vapour, oxynitride, oxysulfide, dust, environmental pollution is serious, seriously deviate from the requirement of ceramic industry cleaner production, and increasing kaolin is applied to the industry such as papermaking, coating, chemical fertilizer, refractory materials, rubber, plastics, petrochemical complex, and the ceramic tile industrial raw material made extremely lacks.Kaolin can be replaced can to alleviate the scarcity of natural resources as ceramic industry raw material so find, the present invention adopts slag and talcum powder etc. to have the characteristics such as water-intake rate is little, void content is little, firing temperature is low, bending strength is large as the floor tile that main raw material generates, and the present invention is the extensive utilization of bessemer furnace slag and alleviates and bring good Social benefit and economic benefit to the burden of environment.
