Problems solved by technology

The above two methods are integral molding process, and the internal pore size is relatively uniform. Such ceramic permeable bricks are used as pavement materials, and there are serious problems in the process of use: the pores of ceramic permeable bricks are easy to be blocked, and the blockages usually come from The soil on the ground (such as green belts, green spaces, flower beds), construction waste and dust at the construction site, sand and dirt brought by people and cars, smog and dust in the air, etc., will seep into the interior of ceramic permeable bricks with rainwater , Block the pore structure, resulting in a decrease in water permeability, or even blockage, the permeable brick loses its water permeable function, and it is difficult to clean, clean and regenerate in the later stage, resulting in a short service life, high cost and difficult maintenance of ceramic permeable bricks
In the prior art, there are also ceramic permeable bricks made into a surface layer and a bottom layer composite structure only by adjusting the particle size of the aggregate. The surface layer is a dense glaze layer or colored layer, which is thin and brittle, and is easily damaged and cracked by force rolling; The surface layer is compounded with the bottom layer by pressing or shower coating, the bonding force between the layers is weak, and it is easy to peel off and fall off when it is bumped by force

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of ceramic permeable bricks, and in particular relates to a method for preparing a multilayer composite structure ceramic permeable brick and the prepared multilayer composite structure ceramic permeable brick. Background technique [0002] In the existing urban construction, open-air public areas, such as sidewalks, parking lots, park corridors, municipal squares, building fronts, and inter-building squares, are mostly paved with impermeable hardened materials such as concrete bricks or ceramic bricks. As a result, natural precipitation cannot infiltrate into the ground in time to replenish groundwater. On the one hand, it is easy to form water accumulation on the ground, making the road slippery and causing safety hazards; on the other hand, natural precipitation needs to be discharged through urban drainage facilities. When the runoff generated by heavy rainfall Exceeding the flood discharge capacity of t...
