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

Abstract

The invention discloses a sintered water permeable brick produced by using coal gangue. The sintered water permeable brick comprises a surface material and a bottom material, wherein the bottom material comprises the following main raw materials in parts by mass: 80-100 parts of coal gangue, 3-12 parts of a bonding base material and 3-12 parts of liquid glue, the surface material comprises the following main raw materials in parts by mass: 0-30 parts of the coal gangue, 0-4 parts of the bonding base material, 0-4 parts of the liquid glue and 0-4 parts of pigment, the bonding base material is one or more selected from bentonite and clay, and the liquid glue is one or more selected from 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 produced by using coal gangue. According to the invention, the water permeable brick prepared by using the coal gangue as a main rawmaterial has high strength, strong frost resistance and excellent 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 coal gangue 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 waste ceramic tiles (waste polished tiles, waste polished glazed tiles, waste tiles, etc.), coal gangue, slag and other solid waste as the main raw materials, together with forming aids, adding an appropriate amount of binder, and forming through two cloths. Fired at high temperature, it is a green environmental protection product. [0003] Permeable bricks can consume a large amount of waste tiles (solid waste such as coal gangue or slag), which not only solves the problem of solid waste treatment at this stage, but also greatly reduces envir...
