Embodiment 1

[0035] Acrylic acid (AA) 21%, methacrylic acid (MAS) 21.5%, polyoxyethylene allyl ester (PA) 11%, ammonium persulfate (APS) 12.5%, carbon black 11%, activated carbon 9%, wood fiber Vegetarian 14%.

Embodiment 2

[0037] Acrylic acid (AA) 21%, methacrylic acid (MAS) 21.5%, polyoxyethylene allyl ester (PA) 11%, ammonium persulfate (APS) 12.5%, carbon black 11%, activated carbon 9%, wood fiber Vegetarian 14%.

Embodiment 3

[0039] Acrylic acid (AA) 21%, methacrylic acid (MAS) 21.5%, polyoxyethylene allyl ester (PA) 11%, ammonium persulfate (APS) 12.5%, carbon black 11%, activated carbon 9%, wood fiber Vegetarian 14%.

[0040] In each of the above embodiments, because the additive of the present invention is also mixed with carbon black, activated carbon and lignocellulose, it can absorb toxic and harmful substances in water.

[0041] At the same time, the present invention also provides a method for making a special additive for permeable concrete for purifying water, which specifically includes the following steps:

[0042] 1) Stir 21% acrylic acid and 21.5% methacrylic acid;

[0043] 2) After the above 1) mixture is stirred evenly, add 11% polyoxyethylene allyl ester and stir;

[0044] 3) Take 12.5% ​​ammonium persulfate as an initiator, add it to the mixture of the above 2), and stir evenly;

[0045] 4) Take 11% carbon black and 9% activated carbon and stir for 10 minutes;

[0046] 5) Add ...

Abstract

The invention discloses a pervious concrete specialized additive for water purification. The pervious concrete specialized additive is prepared from, by weight, 20-22% of acrylic acid (AA), 21-22% of methacrylic acid (MAS), 10-12% of polyoxyethylene propylene ester (PA), 12-13% of ammonium persulfate (APS), 10-13% of carbon black, 8-12% of activated carbon and 10-15% of lignocellulose. The pervious concrete specialized additive has certain compressive strength, and can bear shear and pressure stress of road vehicles, pedestrians and the like on the road surface; certain pervious and breathable properties are achieved, moisture can be rapidly infiltrated into underground in rainy days without water accumulating and reflecting; in addition, sewage infiltrated into underground can be purified, requirements in building a 'sponge city' of natural accumulation, natural infiltration and natural purification are greatly conformed, water resources are saved, and urban ecological environment is protected and improved; therefore, a social effect and ecological effect are generated with the application of the pervious concrete specialized additive.

Description

technical field [0001] The invention belongs to the technical field of concrete additives, in particular to a special additive for permeable concrete for purifying water. Background technique [0002] China's industry has developed rapidly for decades, and the industrial economy has always occupied the primary position in the overall pattern of social development. However, due to the extensive nature of the economic development mode, the industrial structure is heavy and low-level, a large amount of pollutants are discharged, and the environmental pollution is very serious. In most areas, events such as "acid rain" have occurred, and the heavy metal content in the rainwater exceeds the standard, seriously polluting groundwater sources. It affects the development of surface plants and poses a serious threat to the natural ecological environment. And in recent years, the domestic urbanization process is too fast, a large number of buildings occupy farmland, and the cement s...
