Problems solved by technology

[0003] 1. Due to its extremely poor water permeability, it directly blocks the infiltration of rainwater. As a result, the urban groundwater source cannot be replenished, which aggravates the drought phenomenon in the city;
[0004] 2. The reflection of sunlight on the road greatly increases the urban heat island effect;
[0005] 3. It is extremely harmful to the environmental protection and plant protection of the urban area, and directly affects the growth of flowers and trees

Embodiment 1

[0014] a, getting particle size by weight and number ratio is 80% of 15 purpose bauxite pellets (will contain AI 2 o 3 70%-80% of bauxite is crushed by a crusher and a pair of rollers, and then screened by a vibrating sieve), 7% of 250-300 mesh clay fine powder, 6% of talcum powder, and 7% of bentonite. 5%-8% water by weight is fully stirred for about 30 minutes;

[0015] b. Put the stirred mixture into the mold and carry out vibration molding under the pressure condition of 500-800 tons, and the time is controlled within 10-15 seconds;

[0016] c. Send the shaped bricks into the drying room for drying:

[0017] d. Carry out kiln calcination for the dried brick adobe, the temperature is controlled between 1250-1280°C, and it is enough to keep it for 100-120 minutes.

[0018] The product that the present embodiment produces is the common floor tile without color.

Embodiment 2

[0020] a. Take 300 mesh bauxite powder 90%-96% by weight and add 4%-8% grass green dye additive, add the water of 4%-8% of the above-mentioned total weight and fully stir, after mixing After that, it is molded into a mold, dried and calcined according to the traditional process, and then crushed to make grass-green bauxite pellets of about 20 meshes;

[0021] B, get grass green bauxite granular material 80%, 250-300 purpose clay fine powder 7%, talcum powder 6%, bentonite 7% by weight ratio, add the water of above-mentioned gross weight 5%-8% to carry out fully stirring, the time is about 30 minutes;

[0022] C, getting particle size by weight ratio is 80% of 15 purpose bauxite pellets (will contain AI 2 o 3 70%-80% of bauxite is crushed by a crusher and a pair of rollers, and then screened by a vibrating sieve), 7% of 250-300 mesh clay fine powder, 6% of talcum powder, and 7% of bentonite. 5%-8% water by weight is fully stirred for about 30 minutes;

[0023] d. Put 70% of...

Abstract

The composition of said invented environment-protecting type water-permeable brick is composed of (wt%) 75%-85% of bauxite granule material with 6-35 meshes, 7%-10% of clay fine powder with 250-300 meshes, 3%-6% of talcum powder and 4%-8% of bentonite. Said invented water-permeable brick is made up by using the above-mentioned materials in which the bauxite granule material is used as main material through the process of baking at high temperature. Said product has high strength, high hardness, strong bearing capacity and excellent water permeability, and its water-permeable rate can be up to21mm/s.

Description

(1) Technical field [0001] The invention relates to a ground brick for laying sidewalks, in particular to an environment-friendly permeable brick. (2) Background technology [0002] The pavement hardening of urban sidewalk slabs mostly adopts the method of laying marble, glazed tiles, cement bricks to realize at present. Although the pavement paved with the above materials has the effect of being clean, beautiful and dust-proof, it also has some shortcomings: [0003] 1. Due to its extremely poor water permeability, it directly blocks the infiltration of rainwater. As a result, the urban groundwater source cannot be replenished, which aggravates the drought phenomenon in the city; [0004] 2. The reflection of sunlight on the road greatly increases the urban heat island effect; [0005] 3. It is extremely harmful to the environmental protection and plant protection of the urban area, and directly affects the growth of flowers, plants and trees. (3) Contents of the invent...
