The invention discloses a method for preparing acid proof tiles by using waste powder and tail powder of building and daily porcelain. The method comprises the steps of firstly, collecting waste materials of the building and daily porcelain, mixing the collected waste materials, and carrying out ball-milling to prepare waste powder; carrying out component detection, and dividing the waste powder into primary waste powder, secondary waste powder and third waste powder according to the content of silicon dioxide; carrying out ball-milling on 5-15 parts by weight of Guangdong mud, 10-15 parts ofquartz powder, 5-15 parts of Banshan mud, 10-15 parts of Yichun kaolin, 10-15 parts of Jiepai mud, 5-10 parts of Chenzhou mud, 5-15 parts of low-temperature sand, 5-15 parts of Daling bluestone and 2-5 parts of magnesia mud, mixing, and sieving with a 150-200-mesh sieve so as to obtain a mixture. According to the method, the acid proof tiles, which meet acid proof tile use technical standards andcan greatly reduce raw material cost, can be produced by utilizing a great deal of defectives, waste powder and tail powder produced in a production process of the building and daily porcelain, carrying out a great deal of tests and chemical examinations, adjusting a technical formula and improving the manufacturing method.
