Description

A kind of novel water permeable brick and preparation method thereof
Technical field
The present invention relates to building materials technology field, more particularly to a kind of novel water permeable brick and preparation method thereof.
Background technology
At present, global energy, water resources shortage, while desertification area expands the frequent generation with dust storm, make human survival Environment it is increasingly severe, current city dweller occupies residence mainly by with granite, marble, glazed tile, cement and pitch The city square laid etc. fluid-tight material, commercial street, pavement, community activity, the ground in parking lot etc. surround, firmly The harm for changing ground in face of urban environment is very big, when raining, and hardened ground prevents rainwater and directly infiltrates through ground, full area Water makes the trip of people become very inconvenient；Valuable water resource is last as drainage pipeline flows away, and has aggravated municipal drainage and has set The burden applied；A large amount of losses of rainwater cause level of ground water to be difficult to go up, and directly influence the health of urban vegetation so that city In ground flora be difficult to normal growth, aggravate municipal administration greening burden；A large amount of losses of rainwater further aggravate city arid, Water shortage problem, develops new environmental-friendly construction material, improves and beautification environment for human survival is imperative, in the market building materials The dank material primary raw material of some water-permeable bricks, the porous pavement in field etc. is using ceramics or concrete, and ceramic water-permeable brick will Using substantial amounts of ore deposit soil resource, the exploitation of raw material causes the destruction to environment, ceramic mould water-permeable brick complex manufacturing, Er Qietao Porcelain base brick needs to expend the substantial amounts of energy in forming and sintering, and cost is high, and low production efficiency, Environmental Inputs are big, one-time investment Scale is big；Although concrete permeable brick cost is low, thick (the general particles of aggregates of particle on existing concrete permeable brick surface Particle diameter is 3mm-6mm), the macrovoid of abutment surface is permeable, and voidage is easily blocked more than 20% by dust, therefore can not hold High water-permeability energy is held in continuation of insurance；And because space is larger, it is also poor that it is used for water filtration effect；While the face of concrete permeable brick Color is single, and rough surface, unsightly, toughness are bad, and anti-pressure ability is poor, the high molecular polymer water-permeable brick occurred at present, due to The costs of material such as resin are higher, it is difficult to be widely applied.
Research shows, the component proportion of the granularity of particulate material, particulate material and powder-material, is that main influence water-permeable brick is permeable The factor of rate height, is in particular in：The granularity of particulate material is different, water-permeable brick water permeability is different, and granularity is big, thoroughly Aqueous energy is good；Grain composition is different, and intensity, the forming property of water permeability and brick, the water permeability after burning till also are differed；Thoroughly Water brick added water by particulate material and powder-material mix postforming, fire form.Particulate material is skeleton, is major ingredient, and powder-material Auxiliary material, it is made up of compositions such as flux, pore former, binding agents, above composition it is reasonably combined to forming property, drying property Energy, firing property and properties of product play the effect of key, and pore former is mainly organic matter class or carbonate, and pore former is main That, in order to improve the water penetration of product, but the addition of pore former can reduce the forming property and dry tenacity of product, some into Hole agent can also make product produce the defects such as black core.
Water-permeable brick is as a kind of new building and ornament materials, due to the outstanding environmental-protecting performance of water-permeable brick, excellent usability Can and good decorative effect, be the emphasis of research at present, still, due in recent years to the popular research of water-permeable brick, Due to the selection of raw material, the varied of preparation method and without focus on above-mentioned influence water-permeable brick permeability rate height because Element so that the product water-permeable brick quality of preparation is uneven, and part water-permeable brick permeability rate is extremely low, and had a strong impact on water-permeable brick has Sequence develops, while also cause consumer to be difficult to obtain high-quality water-permeable brick, so, science is carried out to the raw material of traditional water-permeable brick It is rational preferred, scientific and reasonable improvement is proposed to preparation method, to improve the quality of current water-permeable brick, to building material field It is significant.
The content of the invention
The present invention is in order to solve the above technical problems, there is provided a kind of novel water permeable brick and preparation method thereof.
Realized particular by following technical scheme：
