The invention relates to a preparation method of a ceramic water permeable brick with a multi-layer composite structure and the ceramic water permeable brick. The preparation method comprises the following steps: 1) crushing and screening ceramic wastes to obtain coarse aggregates, medium aggregates and fine aggregates with different particle sizes; 2) mixing the waste glass powder with kaolin, magnesium oxide, limestone and boric acid, carrying out ball milling and smelting, and carrying out water quenching, grinding and sieving to obtain binder powder; 3) spraying a water glass wetting agentto the medium aggregates, carrying out stirring and mixing, adding the binder powder, and carrying out rolling pelletizing to obtain a coating material; 4) mixing the coarse aggregates with the coating material to obtain a bottom layer material, and mixing the fine aggregates with a water glass wetting agent and the binder powder to obtain a surface layer material; and 5) arranging the bottom layer material, the coating material and the surface layer material from bottom to top in a layered manner, and carrying out pressing, molding and sintering. According to the ceramic water permeable brick, the surface layer and the bottom layer are connected through the middle layer, aggregate particle sizes and pores are gradually transited, the strength is high, the binding force is strong, damageand cracking are avoided after repeated cleaning with a high-pressure water gun, the water permeability is good, recovery is easy, and the service life is long.
本发明涉及一种多层复合结构陶瓷透水砖的制备方法及陶瓷透水砖，该制备方法包括：1)将陶瓷废料破碎筛分获得不同粒度的粗骨料、中骨料和细骨料；2)将废玻璃粉与高岭土、氧化镁、石灰石、硼酸混合球磨后熔炼，经水淬、研磨、过筛得粘结剂粉体；3)向中骨料喷洒水玻璃润湿剂并搅拌混合，加入粘结剂粉体滚动造球制得包料；4)将粗骨料与包料混合得底层料；将细骨料与水玻璃润湿剂、粘结剂粉体混合得面层料；5)将底层料、包料、面层料自下而上分层布料，压制成型，烧结即得。该陶瓷透水砖通过中层连接面层和底层，骨料粒径和孔隙逐渐过渡，强度高，结合力强，可用高压水枪反复清洗不破损、不开裂，透水性能好且易于恢复，使用寿命长。
