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 preparation method of a water permeable brick. The preparation method comprises the steps: (1) crushing aggregates; (2) sieving the crushed aggregates by using sieves with different pore diameters to obtain particles with different particle sizes; (3) proportioning the sieved aggregate particles according to a bottom material formula, adding a bonding agent, and carryingout uniform stirring to obtain a bottom material mixture; proportioning the sieved aggregate particles according to a surface material formula, and adding a bonding agent and pigment to obtain a surface material mixture, wherein the bonding agent comprises a bonding base material and liquid glue; (4) respectively mixing and stirring the bottom material mixture and the surface material mixture; (5)distributing the stirred surface material mixture and bottom material mixture twice, and carrying out compression molding to obtain a green body; and (6) firing the green body in a kiln to obtain a finished product. The water permeable brick prepared by using the preparation method is high in strength, strong in freezing resistance and excellent in water permeability; and the preparation method is few and simple in process and capable of reducing the cost.

Description

technical field [0001] The invention relates to the technical field of permeable bricks, in particular to a preparation method of permeable bricks. 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. Therefore, it has obvious social signifi...
