Abstract

The invention discloses a sintered water-permeable brick produced by using smelting tailings. The sintered water-permeable brick comprises a surface material and a bottom material, wherein the main raw materials of the bottom material comprise, by mass, 80-100 parts of smelting tailings, 3-12 parts of a binding base material, and 3-12 parts of a liquid glue, the main raw materials of the surface material comprise, by mass, 0-30 parts of smelting tailings, 0-4 parts of a binding base material, 0-4 parts of a liquid glue, and 0-4 parts of a color material, the binding base material is one or a plurality of materials selected from bentonite and clay, and the liquid glue is one or a plurality of materials selected from a silica sol solution, a polyacrylamide solution and a guar gum solution. Accordingly the present invention discloses a preparation method of sintered water-permeable brick produced by using smelting tailings. According to the present invention, through the preparation method, by using the smelting tailings as the main raw material, the prepared water-permeable brick has characteristics of 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 smelting tailings 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 tiles (waste polished tiles, waste polished glazed tiles, waste tiles, etc.), smelting tailings, slag and other solid waste as the main raw materials, together with forming aids, adding an appropriate amount of binder, and forming through two cloth , 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 smelting tailings or slag), which not only solves the problem of solid waste treatment at this stage, but also greatly reduce...
