Description
Technical field
The present invention relates to resistant water-permeable brick of a kind of natural-like stone and preparation method thereof, belong to building material field.
Background technology
As the important ring in sponge urban construction system, road surface water-permeable brick plays huge effect.In sponge city
In the construction spring tide in city, its market prospects is extremely wide.Water-permeable brick has the following advantages that：With good permeable, permeability,
Rainwater can be made to rapidly permeate into underground, the supplement soil water and underground water, soil moisture is kept, improve urban ground plant and soil is micro-
Biological life condition；Absorbable moisture and heat, adjust the humiture of earth's surface local space, to regulation urban microclimate, delay
Solution urban heat land effect plays the role of larger；Municipal drainage and pressure of flood, the pollution to preventing public waters and place can be mitigated
Reason sewage has good effect；It is non-slip after not ponding after rain, snow, convenient trip；Surface is in minute asperities, prevents road surface anti-
Light, absorbs the noise produced when vehicle is exercised, can improve the comfortableness and security of vehicle pass-through.
At present, in China, most of water-permeable bricks are typically with natural rubble, building waste, slag waste material etc. for main resource.
In order that water-permeable brick obtains preferable water penetration, particles used particle diameter can not be too big, if but particle particle diameter it is smaller, prepare
Water-permeable brick insufficient strength, often both can not get both for water penetration and intensity.Moreover, the section of waste concrete particle is rougher,
Even with the water-permeable brick prepared by the less waste concrete particle of particle diameter out, its water penetration is also not so good.In First Year
Change is little, but in sleety weather, when especially running into muddy water, the seam that can be blocked inside water-permeable brick due to the mud in muddy water
Gap, substantially reduces water permeability.Water penetration can decline 50% in the 2nd~3 year.And currently common water-permeable brick surface layer it is coarse, dull,
Aesthetics is poor.Therefore needing exploitation, water permeability is more preferable, more attractive practical water-permeable brick.
Although lithotome be used for lay square or street, it is sturdy and durable, with society it is growing, country to ore deposit
The increasing of mountain resource exploitation supervision and the increasingly anxiety of rock material resource, make the use cost more and more higher of lithotome,
It is unpractical to be used for municipal administration consumption using lithotome in majority cities.And the research of permeable imitative Stone brick will overcome with
Upper defect, reduces the waste of natural resources, while significantly reducing cost.Therefore, the water penetration of natural-like stone is researched and developed
The good water-permeable brick of energy is highly desirable to.
The content of the invention
It is an object of the invention to solve currently common water-permeable brick easily to be blocked by sludge water etc., wear no resistance, permeable effect
There is provided resistant water-permeable brick of a kind of natural-like stone and preparation method thereof for the problems such as difference, aesthetics are not enough.The water-permeable brick has resistance to
The advantages of imitative stone material that dirty grade is high, wear-resisting, good water permeability, intensity high, cost is low, surface is smooth is attractive in appearance.
To achieve the above object, the technical solution adopted by the present invention is, a kind of resistant water-permeable brick of natural-like stone, including

The modified fine aggregate by fine aggregate be modified after obtain；The fine aggregate be granite fragment, Dali flag,
One or more in quartz sand, silica sand, particle diameter is 40-80 mesh.
It the ratio of each component is in the modified fine aggregate, coagulant：Aqueous binders：Fine aggregate=1：5：800, antioxygen
The volume of agent is the 0.1%-0.5% of aqueous binders.
The preparation method of the modified fine aggregate is：Fine aggregate is put into mixer, added a small amount of (30% or so)
Aqueous binders be stirred, be gradually added into remaining aqueous binders and antioxidant, stir, be eventually adding rush solidifying
Agent continues to stir 5-10 minutes, you can obtain being modified fine aggregate.
The aqueous binders are:SBT-SP103E aqueous epoxy resins.
Preparation technology is as follows：
(1) modified fine aggregate is prepared
Fine aggregate is put into mixer, the aqueous binders for then adding a small amount of (30% or so) are stirred, by
Remaining aqueous binders and antioxidant are gradually added, is stirred, coagulant is eventually adding and continues to stir 5-10 minutes, you can
Obtain being modified fine aggregate.
(2) the permeable surface layer material of resistant is prepared：First cement, modified fine aggregate, pigment are mixed and mixed thoroughly, add water and
Aqueous binders, impregnating agent are stirred with mixer, standby；
(3) porous base course material is prepared：It is first that flyash, cement, carbide slag, clinker, building waste stirring mixing is equal
It is even, add water and stirred with impregnating agent with mixer, it is standby；
(4) it is molded：The material feeding fabric material distributing machine of step (2) and step (3) is started into cloth, shaping of vibrating is molded.
(5) it is molded permeable adobe and enters maintenance in curing kilns.
Each raw material and index：

Afterwards, presentation quality is without front ixoderm and defect, no losing fangle, flawless, aberration and layering etc., and loss of strength is less than 14%.
About 3%-5% is reduced using water permeability after 3 years.
Water-permeable brick of the present invention has the advantages that：
(1) there is the water permeability of long timeliness
Water-permeable brick of the present invention is by destroying the surface tension of water come permeable, and surface is very fine and close, therefore, is difficult to be blocked up by dust
Extremely, the water penetration with long timeliness.
(2) there is high intensity and aesthetics
Fine aggregate is modified using aqueous adhesive, improves the boundary strength of cement and fine aggregate, while enhancing is permeable
The surface layer intensity of brick.Therefore, water-permeable brick of the present invention has the outward appearance of the light cleaning of similar lithotome, there is high intensity again
And abrasion resistance.
(3) surface layer is pollution-free is not easily blocked
By, the surface smoother of brick modified to fine aggregate, its surface will not form pit or projection, therefore, brick
Surface is easily cleaned, and debris is not had and blocks pore.The function of rainwater retaining, water conservation and purified treatment can be reached.Pass through GB/
The stain resistance grade that T9780-2013 evaluates the sample brick is 0 grade, and surface layer is pollution-free.
The resistance to soiling of water-permeable brick surface layer depends primarily on the height and surface defect (pin hole, crackle, pit of its consistency
Deng) number, consistency is higher, and surface defect is fewer, and its resistance to soiling is better.Original water-permeable brick, its surface is often relatively thicker
It is rough, defect is more and particle inside there is increased number of stomata, this is the basic reason for causing resistance to soiling difference not easy to clean.In the present invention
Just because of the fine aggregate using natural material, after being modified, the high surface of smooth, consistency is obtained, therefore with very
Good resistance to soiling and property easy to clean.
(4) raw material sources enrich, and preparation technology is simply easily controllable, are adapted to large-scale production, wide market.
