Description

A kind of automatically cleaning microporous permeable brick and preparation method thereof based on waste and old mountain flour
Technical field
The present invention relates to water-permeable brick fields, and in particular to a kind of automatically cleaning microporous permeable brick and its system based on waste and old mountain flour Preparation Method.
Background technique
Marble is a kind of very widely used construction material, and Quanzhou of Fujian province and the Yunfu in Guangdong Province are The maximum two processing of stone Nesting Zones in the whole nation produce and process more than 200,000,000 square metres of ability year, and process generation is a large amount of Leftover pieces and dust waste residue are logical for a large amount of marble powder waste residues generated after productional surplus leftover pieces and moulding material redevelopment It is stacked frequently with landfill or is allowed to flow into the processing of the methods of rivers, sea, this processing mode not only results in serious soil Hardened and water quality deterioration, and the particle and dust that generate during discharge pile is abandoned, will also result in serious air pollution and Human respiratory tract's harm.
And water-permeable brick refers to a kind of ground pavement material that its brick body porosity is higher, rainwater can penetrate into ground through brick body Material.As the important component of sponge urban construction, water-permeable brick can effectively absorb, permeate rainwater, can effectively slow down Flood discharge pressure in city reduces rainy day cross flow phenomenon, is of great significance to improvement local environment and weather.However current water-permeable brick By being used for a long time, surface and hole are easy to fall into various dirts formation blockings and cannot remove automatically, weaken permeable The case where effect, ecological effect is poor, and to the more demanding of pumping equipment in use, such as encounters impeded drainage after rain hair It is raw, then it is also easy to produce ponding problem, is both unfavorable for health, damage to the environment, and cause obstacle to people's trip.
Automatically cleaning water-permeable brick is to apply photocatalyst technology in pervious floor tile, and photocatalyst can generate under the irradiation of light Similar photosynthetic light-catalyzed reaction, produces the extremely strong free hydroxy of oxidability and active oxygen, has very strong light Redox function.It is oxidable to decompose various organic compounds and part inorganic matter, organic pollutant is resolved into free of contamination Water (H2) and carbon dioxide (CO O2), thus have the function of extremely strong anti-fouling and self-cleaning, purification air and water, to effectively solve The hole of pervious floor tile is easy blocking and the problem of to Urban Soil Pollution.Automatically cleaning water-permeable brick is right in building ecocity The improvement result of Urban Water Environment is also rather significantly, since the waterproof pavement in city cannot in time penetrate into rainwater Therefore, in city usually there is rainwater accumulation and cross flow phenomenon in underground, and automatically cleaning permeable pavement ground is good due to itself Water permeability, can effectively alleviate the flood discharge pressure of sewerage system.
Currently, also there is many automatically cleaning water-permeable bricks on the market, wherein the Chinese patent of 109704726 A of publication number CN is mentioned A kind of self-purging ceramic tile is supplied, the invention is by lithium base montmorillonite 52 ~ 54, modified alta-mud 33 ~ 35, talcum powder 24 ~ 26, waste and old pottery Porcelain 15 ~ 17, light calcium carbonate powder 10 ~ 12, nano-titanium dioxide 1.7 ~ 1.9, nanometer anion powder 1.2 ~ 1.4, surface treating agent 1.1 ~ 1.3.But some problems such as that there are still permeability rates is low for the water-permeable brick, cost of material is high, intensity is low, pollution environment, and consider A large amount of marble powder residue contamination problems are also on the rise at present, can use its amount mostly and cheap advantage is applied in city It is allowed to play bigger value function in city's construction.Therefore it provides a kind of permeable self-cleaning for having both cheap environmental protection and waste utilization The water-permeable brick for changing effect, is this field technical problem urgently to be resolved.
