Description

A kind of ceramic tile with excellent antifreezing function

Technical field

The present invention relates to floor tile and manufacture field, be specifically related to a kind of to there is ceramic tile of excellent antifreezing 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.

Summary of the invention

The object of this invention is to provide and a kind of there is ceramic tile of excellent antifreezing function and preparation method thereof.

In order to realize object of the present invention, the present invention is by following scheme implementation:

There is a ceramic tile for excellent antifreezing function, be made up of the raw material of following weight part: light calcium carbonate 6-8, montmorillonite 5-6, bessemer furnace slag 30-50, talcum powder 20-25, kaolin 5-10, scrap glass micro mist 15-25, hydroxyethylmethyl-cellulose 1-2, water glass powder 2-4, zinc oxide 2-4, brown sugar 5-8, polyvinylpyrrolidone 0.1-0.3, distilled water are appropriate;

A kind of ceramic tile with excellent antifreezing function of the present invention, be made up of following concrete steps:

(1) be added to by bessemer furnace slag in the distilled water of 2-3 times of weight part and soak 1-2 days, be then added to ball milling in ball mill, ball milling post-drying crosses 200 mesh sieves, at ambient temperature that steel-making slag powder ageing 20-30 days is for subsequent use;

(2) distilled water of brown sugar by 4-6 times amount is dissolved, add polyvinylpyrrolidone again and zinc oxide ultrasonic disperse is even, add the slag mixing and stirring that step (1) is for subsequent use after being uniformly dispersed, be added to after oven dry in baking oven and calcine 1-2 hour under 260-340 ° of C;

(3) light calcium carbonate, montmorillonite, kaolin and talcum powder are added to ball milling in ball mill, after ball milling, 400 mesh sieves crossed by batch mixing, then the bessemer furnace slag of batch mixing and step (2) and remaining remaining component thereof are mixed 2-3 hour in mixer, add appropriate distilled water again and stir formation hygrometric state compound, the old 1-2 of homogenizing days for subsequent use;

(4) by old good material pressurize 3-5 minute under the pressure of 20-25MPa, half dry-pressing compression moulding, then send in high temperature resistance furnace and carry out roasting, wherein under 500 ° of C, 700 ° of C, 900 ° of C, 1100 ° of C, 1200 ° of C, be all incubated 1 hour, take out from resistance furnace after roasting terminates.

Advantage of the present invention is: the present invention is surperficial at slag by oxide coated by zinc, be conducive to spraying glaze, difficult drop-off and cracking, adopt slag and talcum powder as main raw material, instead of kaolin costly, alleviate China ceramic industry to kaolinic dependence, the scrap glass added, reduce the usage quantity of natural Mineral resources as fusing assistant, cost-saving, and there is reduction sintering temperature, the characteristic of percent of firing shrinkage and raising impact resistance, the hydroxyethylmethyl-cellulose added promotes the melting of water glass and cullet under cryogenic, realize the densification of base substrate, the light calcium carbonate added and montmorillonite enhance the hardness of ceramic tile, frost resistance, the characteristic such as not easy to crack, extend the work-ing life of ceramic tile, preparation technology of the present invention is simple, preparation cost is low, noise is little, pollute few, environmental pollution is little, applied widely, application prospect is good.
