The invention belongs to the technical field of building materials and in particular relates to a sintered water permeable brick prepared by taking a ceramic waste material as a main material and a preparation method thereof. The sintered water permeable brick is prepared from the following raw materials in parts by weight: 40 to 60 parts of the ceramic waste material, 25 to 55 parts of ceramic polishing dreg and 5 to 15 parts of kaolin. The preparation method of the sintered water permeable brick comprises the following steps: (1) adding water and mixing the ceramic waste material, the ceramic polishing dreg and the kaolin to obtain a mixture; (2) transferring the mixture treated by the step (1) into a brick pressing machine, and pressing and molding to form a water permeable brick blank; (3) drying the water permeable brick blank obtained by the step (2) to control the moisture content of the water permeable brick blank to be lower than 3 percent; (4) transferring the water permeable brick blank treated by the step (3) into a kiln and sintering; cooling to room temperature along the kiln to obtain the sintered water permeable brick. The water permeable brick is simple in composition and low in cost; the preparation method is simple and the problems that the comprehensive utilization efficiency of the ceramic waste material is low and the environment is polluted are solved.
