preparation example Construction

[0040] The preparation method of the high-efficiency water-absorbing resin water-retaining agent is specifically:

[0041] The first step, the preparation of dispersant solution, 5g emulsifier sorbitan monooleate (sp60) and 5g emulsifier sorbitan monostearate (sp80) are mixed, then join in dispersant cyclohexane, Raise the temperature to 62°C to dissolve and disperse the emulsifier evenly, pass nitrogen gas to remove oxygen for 30 minutes, and obtain a dispersant solution;

[0042] The second step, the preparation of the monomer mixture, neutralizes 40g of acrylic acid with 10g of sodium hydroxide solution at room temperature, then adds 25g of acrylamide and 3g of crosslinking agent N, N-methylenebisacrylamide (MBA), The initiator mixture that 0.3g potassium persulfate and 0.3g sodium bisulfate constitutes is stirred and dissolved and mixed uniformly to obtain a monomer mixture;

[0043] In the third step, the monomer mixed solution is added to the dispersant solution, and af...

[0083] The preparation of embodiment 1 organic compost

[0084] Fully mix 60kg of urban domestic sludge, 40g of waste plants and 50g of livestock and poultry manure, adjust the water content of the mixture to 45% to 50%, control the C / N ratio at 20:1 to 30:1, and put the mixture into a closed space The first fermentation is carried out in the room, the fermentation time is 14h~20h, and then the ventilation is started in stages, the ventilation time is 15min~20min per hour, and the air flow rate is 0.1m 3 / min·m 3 , lasted for 10d-15d, then placed the obtained product outdoors, turned the pile once a day, and piled it for 18d-20d to obtain organic compost.

Embodiment 2

[0085] The preparation of embodiment 2 Chinese herbal medicine nutrient

[0086] Codonopsis 50g, Atractylodes macrocephala 40g, Caulis Spatholobus 25g, Asparagus 30g, Dendrobium 30g, Cnidium 40g, Acanthopanax 30g, Saponis thorn 20g, Ephedra 15g, Honeysuckle 25g, Toosendan 25g, Baibu 15g, white wine Mix 20 g of grass and 15 g of mulberry, add 0.9 kg of ethanol with an alcohol concentration of 95%, heat and reflux for extraction for 3 hours, filter, add 95% ethanol with an alcohol concentration that is 3 times its mass to the filter residue again, and heat and reflux for 3 hours, filtered, and the filtrates were combined, concentrated to remove ethanol, and dried to obtain Chinese herbal medicine nutrients.

Abstract

The invention provides a special vegetation concrete for slope protection and greening by using a high-polymer pellet technique, which is characterized in that the raw materials comprise cement, local soil, plant fibers, a high-water-absorptivity resin water retention agent, a pellet agent, northeast black soil, a concrete reinforcement wire, an organic fertilizer, plant seeds, a Chinese medicinal herb nutrient, an antalkali, a soil stabilizer and water. The northeast black soil, soil stabilizer and know clearly pellet agent are added into the formula of the vegetation concrete, increasing the fertility and stability of the concrete on the premise of ensuring the characteristics of the vegetation concrete, and being more beneficial to growth of the vegetation; the pellet agent is added to increase the formed pores of the concrete and provide plants with larger growth space; the concrete reinforcement wire is added to enhance the strength of the solidified concrete; and the Chinese medicinal herb nutrient is added to provide nutrients for seed growth and promote the growth of the seeds.

Description

technical field [0001] The invention relates to the technical field of ecological restoration engineering, in particular to a novel macromolecule aggregate nutrient matrix specially used for vegetation ecological concrete. Background technique [0002] The research on vegetation concrete originated in the early 1990s. Japan first began to study green concrete, applied for a patent, and established a concrete structure and green design research committee. Developed countries such as the United States and Europe have also carried out research on vegetation concrete since the end of the 20th century. [0003] More and more attention has been paid to the research and application of vegetation concrete in my country. The slope protection vegetation concrete developed by Beijing Institute of Urban Construction Engineering is composed of cement, gravel, sand, ceramsite and water. Jilin Provincial Water Conservancy Company used construction waste bricks and stones as aggregates to ...
