Background technology

ceramic tile is by clay, quartz sand and other inorganic non-metallic raw materials, through tabular or the Bulk ceramic goods of the explained hereafter such as batching, ball milling, powder process, shaping, sintering, is widely used in decorating and the metope of architecture protection thing, structures and ground.Along with the fast development of economy and improving constantly of living standards of the people, the requirement of people to living environment is also more and more higher.But current internal wall brick product still also exists heat insulation and preservation effect difference, and water-intake rate is high, and intensity is low, many weak points such as easy be full of cracks, and without environmental protection characteristic, to existence such as human bodies

Detrimentally affect, cannot reach and purify air, and does not meet the developing direction of modern materials for wall completely.

Summary of the invention

The object of the present invention is to provide that a kind of intensity is high, water-intake rate is low, heat-insulation and heat-preservation is good, capable of purifying air, the interior wall ceramic tile of safety and environmental protection and preparation method thereof.

For achieving the above object, the technical solution used in the present invention is as follows:

A kind of interior wall ceramic tile, is made up of the raw material of following weight part: siliceous shale 25-35, zeolite 20-30, purple clay 15-25, garnet 12-21, modified clay 23-34, malthacite 10-15, zirconium silicate 4-6, chlorite schist 7-13, diatomite 11-19, carbide slag 10-15, shrimp shell meal 5-10, barium carbonate 3-5, boron mud 4-8, plant ash 2-4, lapis amiridis 10-15;

The preparation method of described modified clay is as follows: a, in mass ratio 4-8:3-6:2-3 take bauxitic clay, kaolin, attapulgite, mix, put into the hydrochloric acid soln that concentration is 15-20%, heating in water bath is to 60-70 DEG C, insulation 0.5-1h, filter, be washed with distilled water to neutrality, dry, 460-520 DEG C of calcining 1-2h, pulverize, cross 150-250 mesh sieve, stand-by; B, taking a certain amount of chitosan, to be added to volumetric concentration be in the acetum of 1-2%, stirring and dissolving, be mixed with the chitosan gum liquid solution that concentration expressed in percentage by weight is 10-15%, then the poly-Union carbide A-162 of the Silver Nitrate of solution weight 3-4%, the gac of 2-3%, the nano zine oxide of 1-2% and 2-3% is added, stir 20-30min, stand-by; C, the ratio of the chitosan gum liquid solution of the clay of step a process and step b process by weight 2-3:1 mix, stir into pasty state, dry, pulverize, mistake 200-300 mesh sieve.

The preparation method of interior wall ceramic tile of the present invention, comprises the following steps:

(1) get zeolite, malthacite, purple clay, carbide slag, boron mud, diatomite mixes, pulverize, cross 150-200 mesh sieve, then add the spent pulping liquor of powder weight 8-12%, stir, then make the particle that particle diameter is 1.5-2mm, dry, 1220-1260 DEG C of roasting 5-10min, naturally cools to normal temperature, stand-by;

(2) get siliceous shale, garnet, chlorite schist, zirconium silicate, barium carbonate mix, pulverize, particle mixing 3-5min obtained with step (1) after crossing 200-300 mesh sieve, then remaining raw material mixing 2-3min is added, then the solid content adding compound weight 2-3% is the water glass mixing 30-40min of 30%, leaves standstill 10-15h;

(3) compound that step (2) is obtained is delivered to forming machine compression moulding under 70-80MPa, then the adobe suppressed being delivered in dry kiln and being dried to water content is 2-4%;

(4) by the adobe of drying with the ramp of 4-8 DEG C/min to 650-690 DEG C, insulation 0.5-1h, again with the ramp of 3-6 DEG C/min to 960-1020 DEG C, insulation 1-2h, then 440-480 DEG C is cooled to the speed of 5-10 DEG C/min, insulation 0.5-1h, again with the ramp of 3-6 DEG C/min to 1120-1160 DEG C, insulation 2-3h, is then cooled to 750-800 DEG C with the speed of 4-8 DEG C/min, insulation 1-1.5h, again with the ramp of 5-10 DEG C/min to 1200-1250 DEG C, insulation 3-4h, naturally cools to normal temperature, gets product through edging, packaging.

Above-mentioned modified clay adopts the materials such as Silver Nitrate, gac, nano zine oxide and poly-Union carbide A-162 to work in coordination with Chitosan-coated clay; not only there is good anti-microbial activity; the growth and breeding of some fungies, bacterium and virus can be suppressed; the indoor harmful gas such as all right adsorption-decomposition function formaldehyde, benzene, ammonia, sulfurous gas;, lavatory smelly, rubbish smelly, animal smelly etc. smelly to cigarette plays deodourizing effect; protection human body is healthy; the performances such as the uvioresistant of ceramic tile, ageing-resistant, water tolerance can be improved simultaneously, extend the use work-ing life of ceramic tile.

Beneficial effect of the present invention:

Ceramic tile light weight of the present invention, heat preservation and insulation is given prominence to, and intensity is high, and water-intake rate is low, seismic crack is good, long service life, and can adsorb the objectionable impurities in room air, removes peculiar smell, purify air, safety and environmental protection, has significant economic benefit and social benefit.
