Air-permeable antiskid self-cleaning water-permeable brick and manufacturing method thereof

Abstract

The invention discloses an air-permeable antiskid self-cleaning water-permeable brick. According to the air-permeable antiskid self-cleaning water-permeable brick, tea leaf residues are subjected to room-temperature grinding after carbonization treatment, a photo-catalytic material namely nano titanium dioxide is adsorbed to pore surfaces, and during light illumination, hydroxyl free radicals, super-oxygen ion free radicals and H2O free radicals are generated and have very strong oxidation and decomposition capacities to directly oxidize various organic substances into inorganic small molecules of CO2 and H2O which, when applied to the water-permeable brick, not only can degrade automobile exhaust and the like in the atmosphere but also have relatively strong absorbability. The air-permeable antiskid self-cleaning water-permeable brick disclosed by the invention, which is prepared by carrying out high-temperature sintering on a pore-forming agent of modified sugar filter mud and aggregates of hexacyclic stone, sepiolite and expanded graphite, is air-permeable, antiskid, high in strength and stable in quality, can be produced on a large scale easily, and has a broad market prospect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a breathable anti-slip 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 compressive strength is...

AI Technical Summary

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.
