Description
Technical field
The invention belongs to building material technical field, specifically a kind of road surface ecological permeable bricks and preparation method thereof.
Background technology
The earth's surface of modern city is gradually covered by material water-proof materials such as building and concrete, this fluid-tight earth's surface material
Material prevents rainwater from permeating the ground, so as to cause level of ground water to decline, and storm is once met with, only by sewerage system
Draining is readily formed urban waterlogging.Meanwhile, air-locked road surface can not carry out moisture, heat with air substantially and exchange, no
The temperature and humidity of earth's surface can be adjusted, city " heat island phenomenon " is formd with building.On the other hand, with China industrialize into
Journey fast development, while a large amount of natural resources are consumed, has also incidentally discharged many solid waste, these discarded objects are stacked
The land resource of preciousness is not only taken up, but also severe contamination is caused to environment.Water resources shortage and environmental pollution this two ask greatly
Topic hinders the sustainable development of country, is also the problem that primary study is needed in the current and subsequent some time and is solved.
This New Building Materials of water-permeable brick just arise at the historic moment, and are had broad application prospects in sponge urban construction.
Existing pervious concrete brick low intensity, winter Sometimes When It Rains, if temperature declines suddenly, water freezing, it is possible to freezing；Separately
Outer concrete surface particle is thick, and hole is possible to blocked.Ceramic water-permeable brick complex process, will use substantial amounts of mineral resources,
Cost is high, and environmental requirement is big.High polymer material water-permeable brick is at present also in the starting stage, and cost of material is higher, also limit
Using, it is difficult to it is widely applied.Therefore, developmental research low cost, the simple and environmentally-friendly high performance water-permeable brick of technique have important
Meaning.Polluted for present modern city " heat island phenomenon " problem and trade waste, it is necessary to propose that a kind of road surface is ecological
Water-permeable brick.
The concrete permeable brick low intensity of prior art production, surface particles are thick and hole is possible to blocked, permeable
Rate is lower；Ceramics, high polymer material water-permeable brick cost it is higher, at present also in the starting stage, application it is local less,
It is exactly in addition that price is higher than normal concrete, also limit application.

A kind of road surface ecological permeable bricks, apparent porosity is 0.35~22.92%, and unit weight is 1.87~2.35g.cm-3, anti-folding
Intensity is 5.03~5.64MPa.
Compared with prior art, the device have the advantages that：
The invention provides a kind of low, the environmental and ecological road surface water-permeable brick basic components of cost and preparation method.In raw material
In selection, substantial amounts of solid waste is added, the pollution of environment is alleviated；In production technology, using wound different from the past
New property technique, i.e. accumulation molding simplifies production technology, reduces cost, saves the energy, improves the competitiveness of product.Meanwhile,
Water-permeable brick prepared by the present invention can form big voidage and glass in softening temperature using the close glass particle accumulation of particle diameter
More than degree being incubated at a certain temperature itself has cohesive action to form good, larger space and stable skeleton structure
Permeable brick.Water-permeable brick water permeability prepared by the present invention is excellent, and apparent porosity is 0.35~22.92%, and unit weight is
1.87~2.35g.cm-3, average rupture strength is 5.13MPa, meets national standard, the sea widelyd popularize to our current countries
Continuous urban construction has great significance.It is raw material using solid waste, is economized on resources, by twice laid and environmental protection
Combine, alleviate the pollution of environment；Replaced with this ecological permeable bricks and be currently used in pavement, it is park, cell, wide

Brief description of the drawings
Fig. 1 is process chart of the invention.
Embodiment
With reference to example, the present invention is described in further detail.
Chats composition granule and scrap glass of the present invention play aggregate, and glass fine powder plays powder-material and high-temperature agglomerant is made
With polyvinyl alcohol plays low temperature bonding agent effect.
The present invention relates to a kind of road surface ecological permeable bricks and preparation method thereof, including aggregate, powder-material and organic binder bond.
Using mineral grain and solid waste as aggregate, and the powder-material and organic binder bond of certain particle size range are added, optimization is adjusted
Whole raw material proportioning, the accumulation molding after granulation is burnt till under certain condition, so as to prepare Porous permeable bricks, is observed and is tested
The performance parameters such as firing temperature, the porosity, the density of water-permeable brick.
Referring to Fig. 1, comprise the following steps that：
(1) after cullet grinding, after sieve classification, will screen out more than 8 mesh, 8~20 mesh, 20~40 mesh and 40~80
Purpose level Four glass particle；After mineral crushing and grinding, after sieve classification, screen out more than 8 mesh, 8~20 mesh, 20~40 mesh or
40~80 purposes and mineral grain；
(2) by mass percentage, the mineral grain of 30%~60% any one-level is weighed, 0~20% particle diameter is small
In the glass fine powder of 80 mesh, the glass particle of 0~5% bonding agent and 40%~70% any one-level；To mineral grain
Middle addition glass fine powder, the aqueous solution of bonding agent, stirring make glass fine powder be bonded on mineral grain, are eventually adding glass
Grain, stirs, and granulates, obtains batch；Wherein, mineral grain is identical with the particle size range of glass particle；Wherein, bonding agent
It is 3~7% for the mass fraction of polyvinyl alcohol, and polyvinyl alcohol water solution,
(3) batch is added in grinding tool, natural packing, the mould that then will be equipped with batch is rearmounted through spontaneously drying
In burning till simultaneously 20min~120min in firing furnace at 720 DEG C~860 DEG C, room temperature is naturally cooled to, water-permeable brick is obtained.Using
Spontaneously dry to remove steam, while reducing the energy resource consumption of sintering process.
Cullet in the present invention does not limit species, the place of production, color and composition.
Mineral grain in the present invention is quartz sand, and in addition can also give up porcelain, siliceous original for building masonry wall, floor
One or more kinds of mixing among material, feldspathic raw material
It is described serve binding agent for two kinds of glass fine powder and organic matter polyvinyl alcohol.Polyvinyl alcohol is as normal temperature
Under adhesive use, glass fine powder is used as the adhesive under high temperature.
Described polyvinyl alcohol can be such that powder-material is evenly distributed on aggregate as adhesive in mixing process,
Allow and can uniformly be burnt till in its sintering process, it is scaling-off without being produced because of skewness, or the phenomenon production departed from
It is raw.Under high temperature, polyvinyl alcohol decomposes volatilization.
Aggregate has different particle diameters after described classification, forms grain composition, pore structure is formed it into after accumulation.
Described aggregate can be chosen in same classification or classification connects close to interior glass particle and mineral grain, that is, matches somebody with somebody
Close material in backbone grain distributing scope can not difference it is excessive.
Described granulation is due in various raw material mixed processes, in order to not because the addition of adhesive, produces raw material
The phenomenon of raw caking, so to allow caking to disappear by way of granulation.
Described powder-material glass fine powder itself has cohesive action by glass under softening temperature, will be glued between aggregate
Knot gets up to be formed the stable shaping of skeleton, makes it also as high-temperature agglomerant.
