Embodiment 1
[0034] A production method of antibacterial external wall tiles is characterized in that the implementation steps of the glaze layer are as follows.
[0035] a. Spray a layer of bottom glaze on the surface of the bottom blank, and then dry it naturally to make it lose its fluidity.
[0036] b. Spray a layer of active waterproofing agent to form a layer of hydrophobic hydrocarbon chains.
[0037] c. Spray the glaze slurry on the surface, and obtain the antibacterial glaze slurry layer after natural drying.
[0038] d. Spray a protective glaze isolation layer.
[0039] e. The glazed bricks are dried in a drying kiln for 10 minutes; the drying temperature of the drying kiln is preferably 300°C.
[0040] f. One-time firing in a roller kiln with a temperature of 1180°C, and the firing time is 62 minutes.
[0041] The composition weight ratio of the glaze layer is: 29% of quartz powder, 20% of potassium feldspar, 10% of wollastonite, 5.5% of calcite, 4% of dolomite, 2.5% of cordi...
Embodiment 2
[0046] The body weight ratio of the bottom blank is: 6% of albite powder, 24% of Guangxi potash powder, 8% of Zhongshan stone powder, 23% of washed sand, 16% of Shangnan sand, 17% of Zengcheng Heini, and 6% of Fujian talc. Others are the same as in Embodiment 1.
Embodiment 3
[0048] The body weight ratio of the bottom blank is: 12% albite powder, 28% Guangxi potash powder, 13% Zhongshan stone powder, 12% washed sand, 21% Shangnan sand, 12% Zengcheng Heini, 2% Fujian talc. Others are the same as in Embodiment 1.

Abstract
The invention provides a production method of anti-bacterial external wall tiles, wherein a glazing layer is applied on the tiles through the following steps: (A) spraying a ground glaze layer on a bottom green body, naturally air-drying the ground glaze layer to immobilize it; (B) spraying a layer of active water repellent to form a layer of hydrocarbon chains being hydrophobic; (C) spraying a cover glaze slurry, naturally air-drying the cover glaze slurry to form an antibacterial glaze slurry layer; and (D) spraying a protective glaze insulating layer. The cover glaze includes, by weight, 29% of quartz powder; 20% of potassium feldspar, 10% of wollastonite, 5.5% of calcite, 4% of dolomite, 2.5% of cordierite, 5% of zirconium phosphate, 6.5% of aluminum oxide, 2% of zinc oxide, 4.5% of a frit, 5% of zirconium silicate and 8% of titanium oxide. The anti-bacterial external wall tile is a novel functional ceramic product, has the anti-bacterial, mildew-proofing, decomposition and deodorization effects, can avoid invasion to human from various infections, can keep the external wall of buildings to be clean and can avoid mildew pollution.
Description
technical field [0001] The invention relates to a production method of ceramic tiles, in particular to a production method of external wall ceramic tiles with antibacterial properties. Background technique [0002] The tiles on the exterior walls of buildings are dangerous and difficult to clean after a period of use and soiling. If there is a tile with stronger anti-pollution function, it will bring great convenience. Combining new nano-materials with traditional ceramic materials to produce a new generation of green environment-friendly ceramic products is one of the more successful high-tech applications and development of nano-materials in recent years, with huge market and business opportunities. However, due to the relatively complicated process of the current technology, industrial production is difficult and costly, and it is difficult to promote it on a large scale. Contents of the invention [0003] The technical problem solved by the invention is to overcome t...
