Sintered water permeable brick produced by using furnace slag and preparation method of sintered water permeable brick

Abstract

The invention discloses a sintered water permeable brick produced by using furnace slag. The sintered water permeable brick comprises a surface material and a bottom material, wherein the bottom material is prepared from the following main raw materials in parts by mass: 80-100 parts of furnace slag, 3-12 parts of bonding base material and 3-12 parts of liquid glue; and the surface material is prepared from the following main raw materials in parts by mass: 0-30 parts of furnace slag, 0-4 parts of bonding base material, 0-4 parts of liquid glue and 0-4 parts of pigment; 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 produced by using furnace slag. The water permeable brick prepared from the furnace slag serving as the main raw material in the preparation methodis high in strength, strong in 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 slag 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.), slag, slag and other solid waste as the main raw materials, together with forming aids, adding an appropriate amount of binder, after two times of cloth molding, high temperature Burning is a green environmental protection product. [0003] Permeable bricks can consume a large amount of waste tiles (solid waste such as slag or slag), which not only solves the problem of solid waste treatment at this stage, but also greatly reduces environmental pollution. The...

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
