Description

Ceramic tile capable of purifying air and preparation method thereof
Technical field
The present invention relates to building material fields, and in particular to ceramic tile capable of purifying air and preparation method thereof.
Background technology
As society is constantly progressive and the increasingly raising of people's quality of life, people get over the environmental issue of house fitting-up More to pay attention to.In household fitment process, common interior decoration and ornament materials, such as artificial floor, paint wall covering fabric and Adhesive etc., can release the toxic gases such as formaldehyde, stupid, dimethylbenzene, these toxic gases can generate health very big Harm.
Ceramic tile has extensive and a large amount of application as a kind of domestic finishing material in fitting up indoors.But traditional ceramic tile It has a single function, cannot effectively degrade the toxic gases such as indoor formaldehyde, stupid, dimethylbenzene.
Invention content
It is an object of the present invention to provide a kind of ceramic tiles capable of purifying air and preparation method thereof, to solve traditional ceramic tile It has a single function, cannot degrade the toxic gases problem such as indoor formaldehyde, stupid, dimethylbenzene.
To achieve the above object, an embodiment of the present invention provides following technical solutions:
Ceramic tile capable of purifying air is formed by the raw material proportioning of following parts by weight:Highly dense porcelain stone 5-7 parts, diopside 11-13 Part, 7-9 parts of three-level diopside, 5-7 parts of base slag, soil 11-13 parts of Zhucheng, soil 11-13 parts of Laiyang, saturating white 9-11 parts of stone, green coke 26- 28 parts, 5-7 parts of white clay, 0.8-1.3 parts of nano-titanium dioxide.
Preferably, the ceramic tile is formed by the raw material proportioning of following parts by weight:6.4 parts of highly dense porcelain stone, 12.1 parts of diopside, 8.4 parts of three-level diopside, 6.3 parts of base slag, 11.8 parts of Zhucheng soil, 11.8 parts of Laiyang soil, saturating white 9.2 parts of stone, 26.9 parts of green coke, in vain 6.1 parts of mud, 1 part of nano-titanium dioxide.
The preparation method of ceramic tile capable of purifying air, including following preparation process:
Step 1, by formula rate weigh highly dense porcelain stone, diopside, three-level diopside, base slag, Zhucheng soil, Laiyang soil, thoroughly Bai Shi, green coke, white clay and nano-titanium dioxide, add water to be put into ball mill, after 8-9 hour grinds, remove iron, mistake Sieve, is prepared into mud;
Step 2, the mud obtained by step 1 is passed through into spray drying tower powder, after gained powder is homogenized aging 24 hours, Powder green compact after again will be aging is molded to obtain green compact, and green compact obtain ceramic tile blank after twenty minutes by dry kiln drying;
Step 3, step 2 gained ceramic tile blank is put into kiln, 40 is fired by preheating zone, zoneofoxidation and high-temperature region Minute molding.
Preferably, in step 1, for raw material after grinding, it is 7-8 grams to tail over fineness.
Preferably, in step 2, powder of the mud after spray drying tower, moisture content 6.8-7.2%, green compact The ceramic tile blank of gained, moisture content 1.5-2.0% after dry kiln drying.
Preferably, in step 2, the temperature of dry kiln is between 290-220 DEG C.
Preferably, in step 3, the temperature of preheating zone is between 360-800 DEG C, and the temperature of zoneofoxidation is at 870-1050 DEG C Between, the temperature of high-temperature region is between 1060-1070 DEG C.
Due to the adoption of the above technical scheme, compared with prior art, ceramic tile capable of purifying air of the invention has following Advantageous effect:
Nano-titanium dioxide can activate under the action of daylight or ultraviolet light and generate very strong redox ability, energy It is enough that the damage health such as volatile organic contaminant in air, including formaldehyde, acetaldehyde, stupid and dimethylbenzene is had into poison gas Body oxidative degradation.Titanium dioxide is added among ceramic tile, under the action of natural light or ultraviolet light, can effectively degrade ground room The toxic gases such as interior formaldehyde, stupid and dimethylbenzene, to achieve the purpose that purify air.
In addition to this, nano-titanium dioxide is added in ceramic tile, the substance for being adhered to ceramic tile surface includes greasy dirt and bacterium Deng, can further being aoxidized under the catalytic action of nano-titanium dioxide, become gas or be easy to the substance wiped so that porcelain Brick has better performance, can beautify household.
