Problems solved by technology

[0006] The technical problem mainly solved by the present invention is that when the dust suppressant is sprayed by wet spraying to control dust at present, the water only wets the surface of the dust and cannot penetrate into the inside of the dust, which leads to fast evaporation of water, high water sprinkling frequency, and dust suppression. The defect of poor effect provides a kind of preparation method of wetting type water-locking and dust-suppressing agent

Embodiment Construction

[0024]Put 100-120g of bauxite ore into a three-neck flask filled with 70-80mL of potassium hydroxide solution with a mass fraction of 40%, heat it up to 100-110°C, keep it warm until the ore is no longer dissolved, and filter to remove the filter residue. After cooling down to room temperature, add 30 to 40 g of white carbon black to the three-necked flask, stir and mix at a speed of 300 to 400 r / min for 1 to 2 hours to obtain a zeolite gel; ~5 parts of N, N-dimethyl polyacrylamide, 0.8~1.0 parts of ammonium persulfate were added to 80~90 parts of zeolite gel in sequence, and the stirring reaction was continued for 1~2 hours to obtain the final mixed gel, and the final mixed gel Transfer to a reaction kettle, seal and stand still, heat up to 120-150°C, crystallize for 15-18 hours, cool naturally to room temperature, filter and remove the filtrate to obtain modified zeolite powder; in parts by weight, 70-80 Diatomite with a particle size of 80-100 μm is mixed with water to obta...

Abstract

The invention discloses a preparation method of a wet type moisturizing and dust-suppressing agent and belongs to the technical field of environmental protection. The preparation method disclosed by the invention has the beneficial effects that due to existence of double electric layers in modified zeolite powder, alpha-1, 4 glucosidic bond is hydrolyzed from the inner parts of starch molecules ina random mode by utilizing endonuclease of alpha-starch amylase, and soybean isolate protein contains more polar groups along the own peptide chain skeleton, so that wetting and absorption for dust in the air are improved; due to addition of ox bile, the wettability of the dust-suppressing agent can be improved, the surface tension of water can be reduced, the water can be prevented from condensing into droplets and the volatilization rate can be reduced; since oxidized dextrin swells after absorbing water, the filling capacity is also increased, and in addition, due to water-absorbing groupssuch as hydroxyl groups and the like exposed in the oxidized dextrin, the action force of the formed hydrogen bonds is stronger; calcium chloride doped in the oxidized dextrin can permeate into a spatial network structure of an oxidized-dextrin grafting product, and after the dust-suppressing agent falls to the ground, the calcium chloride absorbs carbon dioxide to form hard calcium carbonate, sothat diffusion of the dust can be controlled and the application prospect is wide.

Description

technical field [0001] The invention discloses a preparation method of a wetting type water-locking and dust-suppressing agent, which belongs to the technical field of environmental protection. Background technique [0002] Dust pollution is harmful to the environment and human health, and has become a world pollution problem. With the deepening of my country's industrialization, the problem of dust pollution is becoming more and more serious. The dust sources mainly include deserts, highways, railways, docks, mines, coal yards, mining, quarrying, cement plants, chemical plants, thermal power plants and construction sites. Dust pollution not only causes a large amount of resource loss, but also pollutes the surrounding environment, affecting people's normal production and life. With the enhancement of environmental protection awareness, people pay more and more attention to the control of dust pollution, and the demand for effective dust prevention and suppression methods i...
