Secondly, sieving the crushed aggregate through sieves with different apertures to obtain aggregate particles with different particle sizes;
thirdly, mixing the sieved aggregate particles according to a base material formula, adding a binder, and uniformly stirring to obtain a base material mixture; and (4) mixing the sieved aggregate particles according to a fabric formula, and adding a binder and a pigment to obtain a fabric mixture.
Specifically, the addition amount of the binder is 6-24 wt% of the aggregate, the binder comprises a binder base material and a liquid glue, and the weight ratio of the binder base material to the liquid glue is 3-12: 3-12. Wherein the binding base material comprises one or more of bentonite and clay, and the clay comprises kaolin, black mud and municipal sludge; the liquid gum comprises one or more of a silica sol solution, a polyacrylamide solution and a guar gum solution.
The binder comprises a binding base material and liquid glue, wherein the binding base material has plasticity and can help molding and enhance the strength of the blank, and the liquid glue can enable the aggregate and the binding base material to be combined more tightly. The two are matched, so that the permeable brick has good strength and good firing performance in the production process.
Specifically, the strength of the permeable brick of the invention mainly refers to two stages: one stage is the molding strength after molding by a press (mainly ensuring that a molded blank is not easy to damage before sintering), and the other stage is the strength of a finished product after sintering (mainly the final service performance of the product, how much pressure the product can bear when in use, for example, a vehicle cannot be directly pressed on, and the like). The liquid glue is mainly used for ensuring the forming performance and the forming strength of the formula; the bonding base material can play a role in bonding particles after being sintered at high temperature, and is used for ensuring the strength of a final product.

The surface layer and the bottom layer of the water permeable brick are different, so the invention needs to be prepared by mixing a bottom material mixture and a surface material mixture, wherein the weight ratio of the bottom material mixture to the surface material mixture is 70-100: 0-30. When the surface material mixture is 0, the water permeable brick only comprises a bottom layer, and the water permeable brick is made into a whole brick. When the water permeable brick needs color, the water permeable brick comprises a surface layer and a bottom layer, and the weight ratio of the used amount of the bottom material mixture to the used amount of the surface material mixture is 70-99.9: 0.1-30.
The base material mixture comprises aggregate and a binder, the surface material mixture comprises the aggregate, the binder and a pigment, and the addition amount of the pigment is 0.4-2 wt% of the aggregate. The kind and amount of the colorant should be adjusted according to the actual product requirement, and the embodiment is not limited to the illustrated examples.
Preferably, the surface material mixture and the bottom material mixture also comprise a forming aid, and the adding amount of the forming aid is 0.01-10 wt% of the aggregate. The forming auxiliary agent can be clay, and comprises one or more of bentonite, kaolin, black mud or municipal sludge, and the function of the forming auxiliary agent is to facilitate the forming of the permeable brick blank in the processing and forming stage.
Further, in order to improve the strength of the water permeable brick and improve the formability of the water permeable brick blank, the aggregate is selected and matched with specific granularity, and the concrete steps are as follows:
the aggregate in the fabric mixture comprises:
100 wt% of 4-20 mesh aggregate.
The aggregates in the fabric mixture are 4-20 meshes, and the grain composition is favorable for forming holes in a finished product, so that the water permeability effect is achieved, and good appearance performance and comfort are obtained.
If the fabric particles are too large, on one hand, the surface of a finished product is too rough and is not suitable for square bricks, people walk on the surface or a bicycle rides on the surface to influence the comfort level, and on the other hand, the flatness of the surface of a green brick is poor, particularly the edge position is uneven, and the attractiveness and the tightness of the laid green brick are poor.
If the fabric particles are too small, the water permeable holes formed between the particles are very small, so that the water permeable brick holes are easily blocked by sewage or sand grains and the like, and the water permeability of the product is influenced after the fabric is used for a period of time.
The aggregate in the base material mixture comprises:
20-50 wt% of 4-20 mesh aggregate
20-50 wt% of 12-40 mesh aggregate
0-60 wt% of aggregate with the particle size of less than 40 meshes.
The aggregates in the base material mixture are 4-20 meshes, 12-40 meshes and less than 40 meshes, and the aggregates of 4-20 meshes, 12-40 meshes and less than 40 meshes are mixed according to a certain proportion, and the grain composition is favorable for forming holes in a finished product and achieving a water permeation effect. Moreover, the broken materials can be basically used up as far as possible under the condition of meeting the final strength of the product, no excess materials are left, the cost is saved, and the waste is avoided.
(IV) respectively mixing and stirring the bottom material mixture and the surface material mixture;
and (V) distributing the stirred fabric mixture and the stirred bed charge mixture twice, and performing compression molding to obtain a blank. The method for forming the cloth twice refers to the prior art.
In the step of press forming, the pressure of the press is 1500-2000T. Preferably, the pressure of the press is 1600- > 1800T.
And (VI) firing the blank in a kiln to obtain a finished product.
In the firing step, the firing temperature is 1100-1220 ℃. Preferably, the firing temperature is 1180-1200 ℃.
Compared with the existing water permeable brick, the water permeable brick prepared by the invention has the following performance:
the compressive strength of the invention is measured by a YQ027SHT4305 microcomputer controlled electrohydraulic servo testing machine under the conditions that the temperature is 27 ℃ and the humidity is 53%, and the sample specification of the water permeable brick is as follows: the length is 68mm, and the width is 64 mm. The standard for the detection of frost resistance is referred to the standard JG/T376-.
From the above, compared with the prior art, the compressive strength of the invention is remarkably improved, the water permeability coefficient is also remarkably improved, and the frost resistance is also good, wherein after 25 times of freeze-thaw cycles, the quality loss is less, and the strength loss is less.
The invention is further illustrated by the following specific examples
