Sintering water permeable brick produced by using crushed stone material and preparation method thereof

Abstract

The invention discloses a sintering water permeable brick produced by using a crushed stone material. The brick comprises a surface material and a backing material, wherein the backing material is prepared from, by mass, 80-100 parts of crushed stone materials, 3-12 parts of bond base materials and 3-12 parts of glue solution; the surface material is prepared, by mass, 0-30 parts of stone crushedmaterials, 0-4 parts of bond base materials, 0-4 parts of glue solution and 0-4 parts of pigment; the bond base material is one or more of bentonite and clay; the glue solution is one or more of ludoxsolution, polyacrylamide solution and guar gum solution. The invention correspondingly discloses a preparation method for the sintering water permeable brick produced by using the crushed stone material. By adopting the method, the crushed stone material is taken as the main raw material, and the prepared water permeable brick is high in strength and freezing resistance and excellent in water permeability.

Description

technical field [0001] The invention relates to the technical field of permeable bricks, in particular to a sintered permeable brick produced by using stone scraps 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 t...

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
