For binding agent in the case where adding in equivalent, the performance comparison of binding agent of the present invention and existing binding agent is as follows：
Binding agent of the present invention innovatively adds in liquid glue, considerably increases the ultimate load of binding agent first, the present invention
The ultimate load of binding agent is up to 150.8N, improves the blank strength of water-permeable brick；Secondly, binding agent of the present invention so that green body is easy
Shaping simplifies molding process, reduces molding difficulty；Finally, binding agent of the present invention is easy to operate, and only the simple batch mixing of need is
Can, the step of without being pre-mixed ball milling, simplify process, reduce cost.
The surface layer of water-permeable brick is different with bottom, and therefore, the present invention needs to mix using bottom material mixture and fabric mixture
It is made, wherein, the dosage weight ratio of bottom material mixture and fabric mixture is 70-100:0-30.When fabric mixture is 0,
Water-permeable brick only includes bottom, and all-body tile is made.When water-permeable brick needs color, water-permeable brick includes surface layer and bottom, and bottom material mixes
The dosage weight ratio for closing material and fabric mixture is 70-99.9:0.1-30.
Bottom material mixture includes aggregate and binding agent, and fabric mixture includes aggregate, binding agent and colorant, the colorant
Addition is the 0.4-2wt% of aggregate.The species and dosage of the colorant should be needed according to actual product and adjusted
Whole, embodiments thereof is not limited to illustrated embodiment of the present invention.
Preferably, the fabric mixture, bottom material mixture further include shaping assistant, and the addition of the shaping assistant is
The 0.01-10wt% of aggregate.The shaping assistant can select clay class, including bentonite, kaolin, black mud or Municipal
One or more in sludge, effect are the shapings for being conducive to water-permeable brick green body in the machine-shaping stage.
Further, in order to improve the intensity of water-permeable brick, the processability of water-permeable brick green body is improved, the aggregate is selected specific
Granularity is arranged in pairs or groups, specific as follows：
Aggregate in the fabric mixture includes：
4-20 mesh aggregates 100wt%.
Aggregate in the fabric mixture selects the aggregate of 4-20 mesh, and this grain composition contributes to finished product to form hole
Hole reaches permeable effect, and obtains good appearance property and comfort level.
If fabric particle is too big, one side finished surface is too coarse, be not suitable for square brick use, people go to above or
Person's bicycle rides over influences comfort level above, and on the other hand, the flatness on adobe surface can be poor, and especially marginal position is uneven
Whole, paving comes out aesthetics and adaptation is poor.
If fabric particle is too small, the permeable hole formed between particle and particle can be very small, so be easy to cause
Water brick hole is very easily by blockings such as sewage or sand grains, the water permeability of influence product after use after a while.
Aggregate in the bottom material mixture includes：
4-20 mesh aggregates 20-50wt%
12-40 mesh aggregates 20-50wt%
40 mesh aggregate 0-60wt% of ＜.
Aggregate selection 4-20 mesh, the aggregate of 40 mesh of 12-40 mesh and ＜ in the bottom material mixture, and 4-20 mesh,
The aggregate of 40 mesh of 12-40 mesh and ＜ mixes according to a certain ratio, and this grain composition contributes to finished product to form hole, reaches permeable
Effect.Moreover, it can also allow the material for breaking off and that can all be finished substantially as far as possible in the case where meeting product final strength, no
Clout is left, it is cost-effective, it avoids wasting.
(4) bottom material mixture and fabric mixture are subjected to batch mixing stirring respectively；
(5) the fabric mixture after stirring and bottom material mixture are obtained into green body through cloth twice and compression moulding.Two
The secondary molding method of cloth is with reference to the prior art.
In the compression moulding step, the pressure of press is 1500-2000T.Preferably, the pressure of press is 1600-
1800T。
(6) green body in kiln through and firing, obtain finished product.
In the firing step, the temperature of firing is 1100-1220 DEG C.Preferably, the temperature of firing is 1180-1200
℃。
Water-permeable brick produced by the present invention and existing water-permeable brick, performance comparison are as follows：
It should be noted that compression strength of the present invention passes through under conditions of being 27 DEG C of temperature, humidity 53%
YQ027SHT4305 microcomputer controlled electro-hydraulic servo testing machines measure, and the specimen sample specification of the water-permeable brick is as follows：Long 68mm, width
64mm.The examination criteria reference standard JG/T 376-2012 of frost resistance are carried out.
From the foregoing, it will be observed that compared with prior art, compression strength of the invention, which has, to be obviously improved, coefficient of permeability there has also been
Significantly improve, and frost resistance might as well, wherein, after 25 Frozen-thawed cycleds, mass loss is few, loss of strength is few.
With specific embodiment, the present invention is further explained below
