Description
Technical field
The present invention relates to inorganic non-metallic material technology of preparing, and in particular to a kind of producer of novel high-strength water-permeable brick
Method.
Background technology
Water-permeable brick is using inorganic non-metallic material as primary raw material, is made after the PROCESS FOR TREATMENTs such as shaping and with compared with flood
The floor tile of permeance property.Water-permeable brick has water penetration, a water-retaining property as new function road pavement material, makes rain during the rainy day
Water is directly permeated the ground, recharge of groundwater, and humidity can be adjusted when being warm, and effectively suppresses city " heat island " phenomenon.Now thoroughly
Water brick has at home and abroad been widely used, and the water-permeable brick seen on domestic market is segmented into two classes, and one kind is by raw material
By crushing, being molded, the water-permeable brick that high-temperature firing forms, it is called ceramic water-permeable brick；It is another kind of be using inorganic non-metallic material as
Primary raw material, organic, inorganic bond is added, be made up of shaping, curing process, due to that need not sinter, so being called
Non-ceramic (unburned) water-permeable brick.
All it is with irregular ceramic bed material or low temperature mostly in addition, in existing water-permeable brick field of material technology
Feldspar etc. is prepared, and also has minority to be molded with natural sand and modified resin, without firing.But these types
Most of water-permeable brick is not very solid, and water penetration is also poor, is unfavorable for puddle of draining in time, one to the rainy day, road surface and field
Ground ponding is very deep, along with dirty mud mixes, largely effects on people's trip, very inconvenient.In existing permeable brick, it is difficult to
Accomplish both to have higher compression strength, stronger rupture strength concurrently there is preferable water penetration again, while production cost is relatively
It is low, meet the demand of market and consumption.
On the other hand, from the perspective of environmental protection and the utilization of resources, with China's rapid development of economy and the people
The continuous improvement of living standard, requirement of the people to environment also more and more higher.Flyash, cullet the like waste arbitrarily abandon,
Discharge or simple landfill, not only occupy good farmland, deteriorate natural environment, also seriously endanger the body that biology produces offspring with people
Health.Particularly flyash dispels with the wind, can aggravate the order of severity of haze sky, cause atmosphere pollution, endanger human health.And
Long-term landfill needs to take substantial amounts of land resource, how these discarded objects is implemented into regenerated resourcesization and comprehensively utilized, is current
The emphasis research topic in resource and environment field.
The content of the invention
The problem of existing for prior art, the invention provides a kind of production method of novel high-strength water-permeable brick, its
Produce obtained water-permeable brick and have higher compression strength, stronger rupture strength concurrently, there is preferable water penetration again.
A kind of production method of novel high-strength water-permeable brick, the water-permeable brick include the raw material of following content：
The production method of the water-permeable brick comprises the following steps：
(1) after mixing flyash, kaolin, cullet, albite by proportioning, then procedure below is passed through successively：Crush,
Sieving plus water mixing, shaping is rolled, is dried, is fired, obtaining semi-finished product；
(2) semi-finished product and adhesive, water are mixed evenly again, by press-molding, burnt till in roller kilns
Finished product.
Further, the time dried described in step (1) is 30 minutes~60 minutes, and dry temperature is from 25 DEG C of steps
250 DEG C are increased to, humidity is gradually reduced to 20% from 60%；The time of the firing is 4~7 hours, and the temperature of firing is
1080 DEG C~1250 DEG C.
Further, in step (2) by semi-finished product, adhesive, water according to proportioning (90~95)：(3~8)：(2~6) mix
Conjunction stirs；The temperature that finished product is burnt till in roller kilns is 1080 DEG C~1250 DEG C, and the time is 4~7 hours.
Further, moved and be put on backing plate with vacuum cup machinery hand handle product after press-molding.
Further, Fe in the kaolin2O3Content be more than 2%.
Further, attrition grinding is carried out with grinding system in the crushing process, the grinding system can be thunder mill
Machine.
Further, sieved during the sieving with the sieve not less than 100 mesh.
Further, the weight of the water added in described plus water mixed process is the 5~8% of raw material.
Further, a diameter of 1.0~3.0mm spheric granules is obtained by the rolling forming process.
Material is transferred in kiln by the drying process to be carried out.Then material is transferred in kiln again and fired.
Further, the water absorption rate of material is no more than 2% after the sintering procedure.
The semi-finished product are particle, it is preferable that the semi-finished product are circular granular.
Further, the density ＞ 1.6g/mm of the semi-finished product3。
The semi-finished product of circular granular are first made in the present invention, then can be greatly enhanced it all for being molded, firing
The intensity of product.In theory, each spheroid has more than no less than 8 contact fusion points, and the intensity of product can be made bigger.Without advising
The then melting tie point non-uniform Distribution of material, its horizontal direction bonding are small.Physical principle：Different isometrical spheroid fillings, it is isometrical
Spheroid voidage is 42%, bead is placed between big ball, then contact point is more than 16 points, and the bead filled between big ball is again
Contact big ball.
Semi-finished product are all with circular granular, and while proof strength, the water penetration of product also improves, its water-permeable passage
The situation that drag reduction, water flowing speed and later stage block has great improvement.
Beneficial effects of the present invention：
(1) water-permeable brick of the inventive method production has very high intensity；
(2) water-permeable brick of the inventive method production has good water permeability；
(3) raw material of the water-permeable brick of the inventive method production largely uses flyash, cullet etc. and discards, is harmful to material,
Both waste material is taken full advantage of, is turned waste into wealth, reduces resource consumption again, protects environment.
