Description
Technical field
The present invention relates to water-permeable brick technical field, especially a kind of water-permeable brick and preparation method thereof.
Background technique
Currently, the non-permeable material such as cement, pitch, marble is mostly used to be laid with ground in urban construction greatly, these are hard
Changing road surface keeps the heat of earth's surface and air, exchange of moisture highly difficult, the poor ability of Natural regulation urban ground temperature and humidity,
Earth's surface absorbs heat difficulty, causes to retain a large amount of waste heats in city space, and ground can also largely be reflected, and radiates solar thermal energy, from
And lead to the city nocturnal temperature phenomenon higher than countryside nocturnal temperature occur.Moreover, hard surface can prevent rainwater in the rainy day
Directly permeate the ground, cause ponding everywhere, influence the comfortableness and security of road, at the same blocked rainwater directly addedly under
The approach of water makes Urban Underground water level be difficult to, and directly affects the healthy growth of urban surface vegetation, and greening is difficult, aggravates
The drought and water shortage problem in city；And ponding injects rivers after pouring in sewer, has aggravated the row of sewerage system and rivers
Let out burden, ground is again extremely dry when fine day, and dusty, environmental degree of comfort substantially reduces.
For this purpose, occur a kind of composite water permeable brick in the prior art, the water-permeable brick to reach solution above-mentioned technical problem, but
It is that it is realized by the adjustment of structure, so that the water permeability of water-permeable brick and bending and compressive strength are improved, still
There is no account for the preparation cost of water-permeable brick for it.
Based on this, occur shortening the time required for solidification using microwave curing processing in the prior art, using constant drop
Warm speed cooling processing comes so that water-permeable brick hot soak condition so that the heating time to water-permeable brick shortens, reduce at
This, and by the improvement to cooling rate, so that it, which reaches, improves permeability rate, bending and compressive strength；It is exactly the patent No.
For a kind of 201010616641.1 sand base water-permeable brick preparation method and 201010165049.4 a kind of water-permeable brick preparation
Method, but it is above-mentioned not next as a whole to the coefficient of permeability of water-permeable brick and density, bending and compressive strength in the prior art
Consider to produce permeable brick product, so that the quality of the water-permeable brick of preparation is still difficult to meet real-life demand, Er Qie
Water-permeable brick curing molding, high temperature are fired, in cooling down and maintenance processes, will lead to water-permeable brick structure occur it is microcosmic
Variation, and then influence the coefficient of permeability of water-permeable brick, bending and compressive strength.
In consideration of it, this researcher combine long-term exploration and production practices, and to the product of acquisition with it is in the prior art
Product compares, and then provides a kind of new approaches for water-permeable brick quality technical field of modification.
Summary of the invention
In order to solve the above technical problems existing in the prior art, the present invention provides a kind of water-permeable brick and its preparation side
Method.The coefficient of permeability of the water-permeable brick of this method preparation is 0.056~0.079cm/s；Density is in 2.1~2.5g/cm3；Anti- folding is strong
Degree is in 130~145kgf/cm2；Compression strength is in 850~900kgf/cm2；Permeable place effectively can be carried out to urban road
Reason avoids that waterlogging occurs, it is ensured that urban groundwater is gone up, and environment is improved；But also can be avoided and jam on broken defect,
So that its service life extends, and density is larger, and coefficient of permeability is higher, can effectively be formed and be filtered to water, avoid nocuousness
Substance largely flows into underground water with rainwater, reduces environmental pollution.
A kind of water-permeable brick preparation method, prepares water-permeable brick prefabricated component, and water-permeable brick prefabricated component microwave curing is handled 20-
30min；Again with the acceleration that heats up for 3 DEG C/min2, it be 1 DEG C/min heating treatment to temperature from heating rate is 300-500 DEG C,
Calcining at constant temperature handles 5-10min again；Then with the acceleration that cools down for 2 DEG C/min2, after cooling processing to temperature≤50 DEG C, watering
Processing.
By carrying out microwave curing processing to water-permeable brick prefabricated component, the change of heating rate is adjusted in control heating acceleration
Change, so that during heating, the variation of microcosmic densification occurs for the structure in water-permeable brick prefabricated component, and makes in water-permeable brick
Gap is increased, and not will cause the phenomenon that leading to water-permeable brick crack of being rapidly heated；Also can be avoided uniformly heating cause it is permeable
Brick structure variation is little, the defect that coefficient of permeability is difficult to improve；And in conjunction with the control of subsequent cooling acceleration, so that permeable
Brick can be in the condition of high temperature for a long time, it is ensured that micro-variations occur for water-permeable brick internal structure, so that permeable improving water-permeable brick
While rate, its density can be improved, enhance anti-folding, compression strength.
The present invention is handled by preparatory microwave curing, then using heating heat treatment, then carries out cooling down processing, most
Water seasoning is handled afterwards, so that the permeability rate of water-permeable brick and density are equalized, improves the bending and compressive strength of water-permeable brick.
