AI Technical Summary

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 binder of the existing permeable bricks requires a separate ball mill. However, the ball milling process takes a long time to operate, and the ball mill equipment is bulky and occupies a large area, which will greatly increase the production cost of the permeable bricks.

Abstract

The invention discloses an adhesive specially used for a sintered water-permeable brick. The adhesive comprises the following components: 20-80wt% of a bonding base material and 20-80wt% 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 and a guargum solution. Correspondingly, the invention also provides a preparation method of the adhesive specially used for the sintered water-permeable brick. When the method provided by the invention is adopted, the adhesive has high ultimate load and a small use amount, 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 special binder for sintered permeable bricks 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 treasure. T...
