Problems solved by technology

Existing permeable bricks are developing towards high density and high strength, and their compressive strength is relatively high, but there are still many defects. On the one hand, the water permeability is very poor. Even if there are bricks with good water permeability, their compressive strength can reach It does not meet the pavement requirements. At the same time, after long-term use of permeable bricks, the surface and pores are easy to fall into various dirt to form blockages and cannot be automatically cleared, which weakens the permeable effect, poor ecological effect, and the requirements for drainage facilities during use. Higher, if the drainage is not smooth after the rain, it is easy to cause water accumulation
On the other hand, the function of the permeable bricks produced by the existing technology is relatively single. They simply allow precipitation to penetrate into the ground through the brick body, and cannot effectively remove the pollutants contained in the water, and cannot purify the sewage that passes through the brick body.

Embodiment Construction

[0012] An ecological self-cleaning permeable brick with montmorillonite tailings, made of the following raw materials in parts by weight: 30 parts by weight of montmorillonite tailings, 20 gravels, 19 clay, 11 high alumina cement, 21 sugar filter mud, 0.8 copper oxide, and sodium nitrate 1.1, peanut shell 4, menthol 0.5, methyl acetate 2.1, nano titanium dioxide 0.6, appropriate amount of water.

[0013] The manufacturing method of described a kind of montmorillonite tailings ecological self-cleaning permeable brick comprises the following steps:

[0014] (1) Dry the peanut shells and place them in a carbonization furnace at a temperature of 450°C, carbonize for 20 minutes without air, cool to room temperature, add nano-titanium dioxide, copper oxide, and menthol to grind for 40 minutes;

[0015] (2) After washing the sugar filter mud, dry it at 50°C, send it to a high-speed mixer, add methyl acetate, sodium nitrate and an appropriate amount of water, stir at a high speed of 1...

Abstract

The invention discloses a montmorillonite tailing ecological self-cleaning water permeable brick. After a carbonized treatment, carbonized peanut shell is ground at room temperature; the pore surface adsorbs a photocatalytic material nanometer titania; and light irradiation is conducted to generate hydroxyl radical, super-oxygen ion free radical and H2O free radical which have strong capacity of oxidization and decomposition to directly oxidize various organic matter into inorganic micomolecules such as CO2 and H2O, etc. By applying the above product into a water permeable brick, the water permeable brick can degrade automobile exhaust and the like in the atmosphere. In addition, the water permeable brick also has strong adsorbability and excellent sound absorption and noise reduction effects. Modified sugar filter mud is used as a pore-forming agent, and montmorillonite and broken stone are used as aggregate. The water permeable brick prepared after high-temperature sintering of the materials has large porosity, excellent self-cleaning effect, high compressive strength, better wear resistance and obvious water permeable effect, is not easy to block, and is not easy for ponding in rainy days. By effective utilization of slags, the product has obvious social, economic and environmental benefits.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a montmorillonite tailings ecological self-cleaning permeable brick and a manufacturing method thereof. Background technique [0002] With the continuous shortage of urban water resources and the pursuit of humanization of the urban environment, the research and development of permeable bricks has attracted extensive attention from experts in materials, environment and municipal engineering. Permeable bricks have good water permeability and moisture retention, which can well alleviate the "urban desertification" and "heat island effect" caused by the city being covered by non-permeable ground pavement. It can also alleviate urban waterlogging to a certain extent and replenish urban groundwater. , regulate the urban environment, and help maintain the urban water balance. Existing permeable bricks are developing towards high density and high strength, and their compress...
