[0036] On the other hand, the present invention also provides a kind of preparation method of permeable brick, and this method comprises:

[0037] (1) curing the mixture of binder and silica sand to form at least one surface comprising a concave permeable brick body;

[0038] (2) The surface of the permeable brick body obtained in step (1) including the depression is coated with a stain-resistant paint, dried to form a stain-resistant paint layer, and at least a part of the depression is not covered by the stain-resistant coating. Paint coverage.

[0039] There is no special requirement for the method of forming the main body of the permeable brick with at least one surface including a depression, and various methods that can be thought of by those skilled in the art can be used. From the aspect of facilitating the preparation of the main body of the permeable brick, it is preferred to use a mixture of binder and silica sand Pour it into the cavity of the mold for making the ...

Embodiment 1

[0060] This embodiment is used to illustrate the preparation of the permeable brick provided by the present invention.

[0061] 100 grams of quartz sand with a particle diameter of 0.1-0.25 mm, 4.6 grams of hydrogenated bisphenol A epoxy resin (purchased from Wuhan Shizishan Paint Factory), 1.4 grams of aliphatic polyamine curing agent (purchased from Yuanhong Applied Materials Co., Ltd., model is H-3528), 0.12 g of γ-glycidyl etheroxypropoxypropyl trimethoxysilane (purchased from Beijing Shenda Fine Chemical Co., Ltd., model is A-187), After mixing 0.012g of light stabilizer UV-320, 0.006g of antioxidant 1010, 1g of perlite powder and 3g of alcohol, fill it into the cavity of the mold to form the main body of the permeable brick. The bottom surface of the cavity is inlaid with stones with a sphericity of 0.85 and a diameter of 5-7mm. The height of the stones on the bottom surface of the cavity is 4-8mm. The distance between the center points of two adjacent stones in the same...

Abstract

The invention discloses a water permeable brick. The water permeable brick is characterized in that the water permeable brick comprises a water permeable brick main body and a pollution resistant coat, the water permeable brick main body contains silica sands and a cured binder, at least one surface of the water permeable brick main body comprises a recess, the recess-comprising surface is covered with the pollution resistant coat, and at least the recess part is not covered with the pollution resistant coat. The invention also discloses a making method of the water permeable brick. The method is characterized in that the method comprises the following steps: 1, curing a mixture comprising a binder and silica sands to form the water permeable brick main body having at least one surface comprising the recess; and 2, coating the recess-comprising surface of the water permeable brick main body obtained in step 1 with a pollution resistant coating to form the pollution resistant coat, and allowing at least the recess part to be not covered with the pollution resistant coating. The water permeable brick has the advantages of excellent pollution resistant, excellent compressive strength, excellent water permeability, excellent wear resistance, excellent skid resistance, and suitableness for laying on various grounds.

Description

technical field [0001] The invention relates to a permeable brick and a preparation method thereof. Background technique [0002] At present, the floors of city squares, commercial streets, sidewalks, community activity sites, parking lots, etc. are mainly paved with impermeable materials such as granite, marble, glazed tiles, cement and asphalt. The impermeable floors are very harmful to the urban environment. When it rains, the impermeable ground completely prevents the rainwater from infiltrating directly into the ground, and the accumulated water makes it very inconvenient for people to travel; the precious water resources eventually flow away with the drainage pipes, which increases the burden on urban drainage facilities; The large loss of rainwater makes it difficult for the groundwater level to rise, which directly affects the health of urban vegetation, makes it difficult for the surface plants in the city to grow normally, and increases the burden of municipal gree...
