[0052] This embodiment is used to illustrate the permeable brick provided by the present invention and its preparation.

[0053] (1) Formation of the second aggregate particles:

[0054] Put 10kg of quartz sand into the muffle furnace, roast at 300°C for 10min, then transfer the roasted quartz sand to the sand mixer, and add 0.24 kg of ME-2 water-based epoxy resin, 0.05 kg of carbon black (purchased from Dainichi Seika Chemical Co., Ltd., H190), continue to stir, and when the temperature drops to 130 ° C, add 0.6 kg of hexamethylene tetrachloride to the mixture amine, and stirred for 120s to obtain coated quartz sand, the average particle diameter of which was measured by a digital stereo microscope to be 1 mm.

[0055] (2) Formation of permeable bricks:

[0056] Mix 600g of ceramsite (purchased from Anhui Zijin Ceramsite Factory, with an average particle diameter of 7mm), 12g of cement and 10g of water to obtain a mixture that forms a permeable base; lay the mixture to a si...

Embodiment 3

[0058] This embodiment is used to illustrate the permeable brick provided by the present invention and its preparation.

[0059] (1) Formation of the second aggregate particles:

[0060] Put 10kg of raw sand into the muffle furnace, roast at 300°C for 10 minutes, then transfer the roasted raw sand to the sand mixer, and add 0.12 kg of HD-RHA308 water-based acrylic resin, 0.03 kg of carbon black (purchased from Dainichi Seika Chemical Co., Ltd., H190), and continue to stir for 80 s to obtain the coated raw sand. The average particle diameter measured by a digital stereo microscope is 0.5 mm.

Abstract

The present invention provides a water permeable brick, which comprises a water permeable base layer and a water permeable surface layer covering on the water permeable base layer, wherein the water permeable base layer is formed through curing a mixture containing a first aggregate and a first binder, the water permeable surface layer is formed through curing a mixture containing a second aggregate and a second binder, and the second binder contains a hydrophilic binder. The water permeable brick further comprises at least a water flow pore channel positioned inside the water permeable base layer, wherein the water flow pore channel penetrates through both side surfaces of the water permeable base layer. The water permeable brick has excellent water permeability, and can not cause foundation loosing.

Description

technical field [0001] The invention relates to a permeable brick. 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 greening; the large loss of rainwater...
