Description
Technical field
The present invention relates to a kind of water-permeable brick preparing technical field, particularly relate to the preparation side of a kind of mine tailing flint clay water-permeable brick
Method.
Background technology
At present, mostly using the non-permeable materials such as cement, pitch, marble to lay ground in urban construction, these are hard
Changing road surface makes earth's surface and the heat of air, exchange of moisture highly difficult, the poor ability of Natural regulation urban ground temperature and humidity,
Earth's surface absorbs heat difficulty, retains a large amount of waste heat in causing city space, and ground also can be reflected in a large number, radiates solar thermal energy, from
And cause that the phenomenon that city nocturnal temperature is higher than countryside nocturnal temperature occurs.And, when the rainy day, hard surface can stop rainwater
Directly permeate the ground, cause hydrops everywhere, affect comfortableness and the safety of road, blocked simultaneously rainwater directly the most addedly under
The approach of water, makes Urban Underground water level be difficult to go up, and directly affects the healthy growth of urban surface vegetation, greening difficulty, increases the weight of
The drought and water shortage problem in city；And hydrops injects rivers after pouring in sewer, increase the weight of the row of sewerage system and rivers
Letting out burden, during fine day, ground is the most extremely dry, stirs up a cloud of dust, and environmental degree of comfort is substantially reduced.
To this end, those skilled in the art are by further investigation, develop the water penetration material of some water-permeable brick, porous pavements etc.
Material.Such as, CN 101528630A discloses a kind of composite water permeable brick, and this water-permeable brick includes permeable top layer and porous base course, permeable

0.7～0.9wt%, water accounts for 3.5～6.0wt%.Compared with ceramic water-permeable brick, the present invention can be greatly lowered road surface water-permeable brick
Production cost, is not required to calcining simultaneously, can save the energy, protects environment.Compared with current existing common cement-base water-permeable brick, keep away
The shortcoming having exempted from freeze-thaw resistance difference.
The Chinese patent of Patent No. CN200410039203 discloses a kind of environmental protection water permeable brick structure and preparation method thereof, and this is saturating
Water brick includes the upper brick layer integrally fired and lower brick layer, and the thickness of this lower brick layer accounts for the 75～95% of water-permeable brick gross thickness,
On this, brick layer and lower brick layer are formed by the ceramic fine particle and coarse grain being mixed with additive and bonding agent respectively, and composition after saturating
The comprcssive strength of water brick is more than specification value 300kgf/cm2, and rupture strength is at more than 50kgf/cm2, and permeability rate is more than
0.035ml·cm/mm2/sec.Above-mentioned water-permeable brick according to setting procedure by waste ceramic processed, through high temperature sintering molding, can
Make the increase of water-permeable brick intensity, easy coloring, can back washing and may filter that impurity and tool breathability；Be applicable to pavement, ramp, from
Runway and the water-permeable brick of edge of pool.
The Chinese patent of Patent No. CN200610159648 discloses the production method of a kind of composite ceramic water-permeable brick, should
Method with include combustible industrial residue for bottom aggregate, with waste ceramic particle for surface layer aggregate, its grain composition is all: cross 10～
The material of 20 mesh sieves accounts for 55～65, and the material crossing 20～30 mesh sieves accounts for 35～45；By additional appropriate high-temperature agglomerant and organic viscous
Knot agent CMC, through dispensing, old, molding, be dried, calcining process and obtain product.Said method is mainly by optimizing grain composition
Utilizing combustible that industrial residue itself contains as pore former dexterously, and two-layer uses different the most former up and down
Material, makes that the product not only water penetration that obtained by the method is strong, good water-retaining property, intensity are high, but also simplifies the technique mistake of brickmaking
Journey, reduces production cost.This product is a kind of reason for laying the public places such as footpath, parking lot, airport, square
Think product.
