Permeable brick and its preparation method

Abstract

The invention provides a permeable brick, which comprises a permeable brick main body and a contamination-resistant dope layer. The permeable brick main body contains silica sand and a solidified binder. The contamination-resistant dope layer is uniformly sticked to at least one surface of the permeable brick main body, and at least part of micropores on at least one surface of the permeable brick main body is not covered by the contamination-resistant dope layer. The invention also provides a preparation method of the above permeable brick. The method contains steps of uniformly covering at least one surface of the permeable brick main body with a contamination-resistant paint and drying to form the contamination-resistant dope layer. The amount of the contamination-resistant paint depends on the condition that part of the micropores on at least one surface of the permeable brick main body is not obstructed by the contamination-resistant material. The permeable brick provided by the invention has excellent water penetration, is contamination resistant and antiskid, and requires low production energy consumption.

Description

Technical field

[0001] The invention relates to a permeable brick and a preparation method thereof. Background technique

[0002] At present, the grounds of city squares, commercial streets, sidewalks, community venues, parking lots, etc. are mainly paved with impervious materials such as granite, marble, glazed tiles, cement and tar. The impervious ground is very harmful to the urban environment. When it rains, the impervious ground completely prevents rainwater from penetrating directly into the ground, and the accumulation of water on the ground makes people's travel very inconvenient; the precious water resources finally flow away with the drainage pipeline, which increases the burden of urban drainage facilities; The massive loss of rainwater makes it difficult for the groundwater level to rise, which directly affects the health of urban vegetation, making it difficult for surface plants in cities to grow normally, and increasing the burden of municipal greening; the massive...

Examples

Embodiment 1

[0034] 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 H-3528), 0.12 grams of γ-glycidoxypropoxypropyltrimethoxysilane (purchased from Beijing Shenda Fine Chemical Co., Ltd., model A-187), After mixing 0.012 g of light stabilizer UV-320 and 0.006 g of antioxidant 1010, 1 g of perlite powder and 3 g of alcohol, they are filled into the mold to form a permeable surface layer;

[0035] 100 grams of quartz sand with a particle diameter of 0.2-0.5 mm, 3.8 grams of hydrogenated bisphenol A epoxy resin (purchased from Wuhan Shizishan Paint Factory), 1.2 grams of aliphatic polyamine curing agent (purchased from Yuanhong Applied Materials Co., Ltd., model H-3528), 0.1 g of glycidoxypropyltrimethoxysilane (purchased from Beijing Shenda Fine Chemical Co., Ltd., model A-18...

Embodiment 2

[0038] The water-permeable brick body was prepared according to the method of Example 1, except that the quartz sand of the water-permeable surface layer was replaced by quartz sand with a particle diameter of 0.4-0.8 mm to make the water-permeable brick body.

[0039] On the surface of the main body of the prepared permeable brick, with 350g / m 2 Spray the water-based fluorocarbon paint (Beijing Zhitu Chemical, water-based fluorocarbon emulsion ZT-302) with the amount used, and then dry it at 80°C for 6 hours to make permeable bricks. After calculating the adhesion amount of the stain-resistant coating layer of the permeable brick is 200g / m 2 .

Embodiment 3

[0041] The water-permeable brick body was prepared according to the method of Example 1, except that the quartz sand of the water-permeable surface layer was replaced by quartz sand with a particle diameter of 0.2-0.45 mm to make the water-permeable brick body.

[0042] On the surface of the main body of the prepared permeable bricks, 193g / m 2 Spray the solvent-based fluorocarbon liquid (Beijing Beimu New Material, 881-Y11 fluorocarbon paint) with the amount used, and then dry it at 60°C for 4 hours to make permeable bricks. After calculation, the adhesion amount of the stain-resistant coating layer of the permeable brick is 110g / m 2 .
