Problems solved by technology

The cost of laying is high and there is no water retention and permeable function. If stains are stained, it is difficult to clean up, which will affect the appearance. Although glazed tiles have good stain resistance, they are not slippery, especially in rainy or snowy days. However, the existing permeable bricks are not widely adopted by the market due to technological defects.

Embodiment 1

[0056] A method for preparing water-retaining and permeable bricks. In terms of parts by mass, 50 parts of stone materials with a particle size below 2mm and 5 parts of P.I42.5 cement cement are pre-configured, fully mixed and stirred evenly with a brick making machine; and then pressed Add 1 part of hydrolyzed polymaleic anhydride, 0.1 part of calcium chloride and 10 parts of water respectively, mix thoroughly and evenly, discharge the material, press molding, demoulding, and curing for 7 days to obtain a water-retaining and permeable brick.

Embodiment 2

[0058] A method for preparing water-retaining and permeable bricks. In terms of parts by mass, 120 parts of stone materials with a particle size of 0.1-2mm or less and 25 parts of P.II42.5 cement cement are pre-configured and fully mixed with a brick making machine. Then add 2 parts of hydrolyzed polymaleic anhydride, 1 part of sodium sulfate and 25 parts of water respectively in proportion, fully mix and stir evenly, discharge the material, press molding, demoulding, and curing for 8 days to obtain a water-retaining and permeable brick.

Embodiment 3

[0060] A method for preparing water-retaining and permeable bricks. In terms of parts by mass, 70 parts of stone materials with a particle size of 1-2 mm or less and 10 parts of P.S42.5 cement cement are pre-configured, and fully mixed and stirred evenly with a brick making machine; Then add 1.2 parts of hydrolyzed polymaleic anhydride, 0.3 parts of calcium nitrate and 15 parts of water respectively in proportion, mix thoroughly and evenly, discharge the material, press molding, demoulding, and curing for 9 days to obtain a water-retaining and permeable brick.

Abstract

The invention provides a water-retention and water-permeable brick and a preparation method thereof. The water-retention and water-permeable brick is prepared by adopting a specific amount of cement, a stone stock, a gelling agent, a coloring dispersant and water. The water-retention and water-permeable brick has the advantages of low cost, high compression strength, high breaking strength, water-retention and water-permeable functions and the like, wherein the stone stock can be selected from waste exploited stones, so that not only can comprehensive utilization of the waste stones be realized but also the ecological environment is cleaned, and particularly the problem of dust raising caused by deposition of a large amount of stone chips is solved. The preparation method of the water-retention and water-permeable brick is simple in process, does not need kilning, has a significant energy conservation and emission reduction effect, has a low manufacturing cost and significant social and economic benefits, is reasonable in process design, is simple and convenient in manufacturing, generates no secondary pollution, and is suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of rainwater treatment, in particular to a water-retaining permeable brick and a preparation method thereof. Background technique [0002] The research and application of water-retaining and permeable bricks began in Japan in the 1970s more than 100 years ago. In order to solve the problems of foundation subsidence caused by pumping groundwater in the country, the "underground restoration policy for rainwater" was proposed, and a small amount of fine aggregate was developed. The pressed bricks (commonly known as magic bricks) that are both permeable and water-retaining are used to pave trails and light vehicle roads. After 40 years of development, Japan's urban air quality has made great progress. [0003] Throughout our country, at present, the ground of squares, commercial streets, sidewalks, community activity places, parking lots, etc. in our country is mainly paved with non-water-retaining and permeable...
