Embodiment 1

[0025] like Figure 1-2 As shown, the sponge brick of this embodiment includes a sponge brick base 1, and the sponge brick base 1 deposits mesh-like starch granules on the microporous plastic by a liquid phase deposition method, and then presses the microporous plastic with the starch granules deposited on it. It is made by injection molding into a brick body by a conventional method; a foot massage layer 2 made of foam plastic is laid on the top of the sponge brick base 1 in a glued manner, and the top surface of the foot massage layer 2 is integrally formed with a number of elastic protrusions 2.1 adjacent to each other. The foot massage layer 2 between the two protrusions 2.1 is provided with leaking holes that run through the foot massage layer; a plurality of permeation tubes 3 are pre-embedded in the sponge brick matrix 1, and several permeation holes are opened in the permeation tube 3 circumferential direction, and the permeation tubes 3. One end passes through one sid...

Embodiment 2

[0035] The specific structure of the sponge brick in this embodiment is the same as that in Example 1, but the sponge brick matrix is ​​made by adsorbing mesh-like starch particles on the cement-based brick body with micropores by negative pressure method.

[0036] The preparation process of above-mentioned reticular starch granules is:

[0037] In the first step, the starch extracted from starch processing wastewater is soaked in an appropriate amount of 10% sodium hydroxide solution for 10 hours, then ground, and the ground slurry is spray-dried to obtain superfine starch;

[0038] In the second step, pour the superfine starch prepared in the first step into an appropriate amount of deionized water, add α-amylase in an amount of 0.1% of the superfine starch, adjust the pH to 6.2-6.4 with hydrochloric acid, and disperse by ultrasonic for 40 minutes , and then stirred at constant temperature for 0.5h, the reaction was completed, the enzyme was inactivated, and the enzymolyzed ...

Abstract

The invention discloses a sponge brick. The sponge brick comprises a sponge brick base body, mesh-shaped starch particles are deposited on a microporous plastic through a liquid depositing method, andthen the microporous plastic deposited with the starch particles is subjected to injection molding to form a brick body so as to obtain the sponge brick, or mesh-shaped starch particles are adsorbedto a cement-based brick body with micropores through a negative-pressure method to obtain the sponge brick. The water absorption of the sponge brick is quite high, every gram of the sponge brick can absorb 500 g of water, the problem of waterlogging of urban road surfaces is solved effectively, wastes are utilized, and the manufacturing cost of the sponge brick is reduced.

Description

technical field [0001] The invention relates to the technical field of sponge city construction, in particular to a sponge brick and a preparation method thereof. Background technique [0002] The construction of sponge city is to realize the functions of absorbing, infiltrating, stagnating, storing, purifying and discharging rainwater for various urban facilities, so as to promote the local consumption and utilization of urban rainwater and solve the problem of urban waterlogging. The permeable bricks in the prior art have limited water absorption effect and are easy to absorb and saturate, so there is still water accumulation. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the object of the present invention is to provide a sponge brick and a preparation method thereof. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a sponge brick, comprising a sponge brick base,...
