Sintered water-permeable brick produced by using archaized brick broken material and preparation method of sintered water-permeable brick

Abstract

The invention discloses a sintered water-permeable brick produced by using an archaized brick broken material. 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 the archaized brick broken material, 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 archaized brick broken material, 0-4 parts of a bonding base material, and 0-4 parts of liquid glue; the bonding base material is one or more of bentonite and clay; and the liquid glue is one or more selected from the group consisting of a silica sol solution, a polyacrylamide solution anda guar gum solution. Correspondingly, the invention discloses a preparation method of the sintered water-permeable brick produced by using the archaized brick broken material. By adopting the method provided by the invention, the archaized brick broken material is used as the main raw material, and the prepared water-permeable brick 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 antique brick 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 ceramic tiles (waste polished tiles, waste polished glazed tiles, waste tiles, etc.), antique brick fragments, slag, etc. Molding, high-temperature firing, is a green environmental protection product. [0003] Permeable bricks can consume a large amount of waste tiles (solid waste such as antique brick 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 urb...

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
