Sintered water-permeable brick which is not blocked easily and preparation method of sintered water-permeable brick

Abstract

The invention discloses a sintered water-permeable brick which is not blocked easily. The brick comprises a surface material and a bottom material, wherein the bottom material comprises the main raw materials of: in parts by mass, 80-100 parts of aggregate, 3-12 parts of a bonding base material, 3-12 parts of liquid glue and 0.1-5 parts of glaze, and the surface material comprises the following main raw materials of: in parts by mass, 0-30 parts of the aggregate, 0-4 parts of the bonding base material, 0-4 parts of the liquid glue, 0-2 parts of the glaze and 0-4 parts of color materials; the bonding base material is one or more of bentonite and clay, and the liquid glue is one or more of a silica sol solution, a polyacrylamide solution and a guar gum solution. Correspondingly, the invention discloses a preparation method of the sintered water-permeable brick. The water-permeable brick has high strength, strong frost resistance and excellent water permeability, particles or fiber substances in rainwater and other sewage are not hung on walls easily, and hole gaps of the water-permeable brick are not easily blocked.

Description

technical field [0001] The invention relates to the technical field of permeable bricks, in particular to a sintered permeable brick which is not easily blocked and a preparation method thereof. Background technique [0002] Permeable bricks are a new century-old environmentally friendly building material that was born to alleviate urban waterlogging, maintain water, maintain urban ecological balance and build a sponge city. It uses solid waste such as waste tiles (waste polished tiles, waste polished glazed tiles, waste tiles, etc.), stone fragments, slag, etc. , fired at high temperature, is a green environmental protection product. [0003] Permeable bricks can consume a large amount of waste tiles (solid waste such as stone fragments or slag), which not only solves the problem of solid waste treatment at this stage, but also greatly reduces environmental pollution. The produced ceramic permeable bricks can be directly used in urban construction, turning waste into trea...

Problems solved by technology

And the ultimate load of the binder is low, generally around 64.8N, resulting in low strength of the green body after molding

[0007] In addition, the existing technical process of permeable bricks is relatively complicated, with many production processes, long time consumption and high cost. The process flow chart is as follows figure 1 shown

see figure 1 , the binder of the existing permeable bricks requires a separate ball mill, but the ball milling process takes a long time to operate, the ball milling equipment is bulky and occupies a large area, which will greatly increase the production cost of the permeable bricks

[0008] Moreover, the existing permeable bricks are very easy to block after being used for a certain period of time. This is because the pores of the permeable bricks are small and extremely irregular. Particles or fibrous substances are not easy to pass through the pores of permeable bricks, thereby blocking their pores
