Photocatalysis exterior wall tile and method of producing the same

The invention relates to a ceramics tile and a preparation method thereof, in particular to a photocatalysis exterior ceramic tile and the preparation method thereof, belonging to the material technical field. The preparation method of the product of the invention has the following steps: materials are arranged by weight proportion; conventional ball milling is carried out on putty powder, talcum powder, zinc oxide, albite, carclazyte, dolomite and water for 11-13 hours; nano dioxy titanium is added for continuing the ball milling for another 1-3 hours; the specific parameters are as follows when the ball milling is over: proportion: 1.65-1.85, fineness: 0.015-0.025mm, sizing agent flow rate: 28-32 seconds, and water: 30-35%; the ground materials are filtered through a 180-mesh sieve; after slurry discharging in a de-ironing trough, the ground materials are put in a transit barrel for aging for 10-14 hours; at the temperature of 1200 DEG C, shaped blank is burned for 40-60 min; when the finished tiles are man
