Problems solved by technology

In the mine, the road surface is often bumpy, coupled with the wind force, the ore powder on the surface of the transport vehicle is scattered on the ground, resulting in dust pollution, the concentration of the ore powder can even reach a suffocating level, and the visibility is extremely reduced
This not only caused economic losses to relevant enterprises and units, but also caused serious pollution to the environment along the way, and seriously affected the production and life of surrounding residents.
The current solution is to sprinkle water on the road surface, but this method is not only time-consuming and labor-intensive, but also has poor effect

Embodiment 1

[0028] Take 0.6g of water-based epoxy resin (solid content 49~51%) (commercially available), stir and dissolve in 93.33g of tap water, after fully dissolved, take 0.2g of acetamide and dissolve in the above solution, and then 0.8g of polyvinyl alcohol Dissolve in the above solution, then dissolve 0.07 g of sodium stearate in the above solution, and add 5 g of AlNiCo nanoparticles modified with hydroxyl groups on the surface, and stir well to obtain a magnetic dust suppressant.

Embodiment 2

[0030] Take 0.9g of water-based epoxy resin (solid content 55-56%) (commercially available) and dissolve it in 90.71g of tap water. After fully dissolving, take 0.3g of acetamide and dissolve in the above solution, and then dissolve 1.0g of polyacrylic acid in the above solution. In the solution, dissolve 0.09 g of sodium stearate in the above solution, and add 7 g of SrFeO19 nanoparticles modified with hydroxyl groups on the surface, and stir well to obtain a magnetic dust suppressant.

Embodiment 3

[0032] Take 1.0g of water-based epoxy resin (50% solid content) (commercially available) and dissolve it in 90.9g of tap water. After fully dissolving, take 0.5g of acetamide and dissolve in the above solution, and then dissolve 0.5g of polyvinylpyrrolidone in the above solution. In the solution, 0.1 g of sodium stearate is dissolved in the above solution, and 7 g of SmCo nanoparticles modified with hydroxyl groups on the surface are added, and the magnetic dust suppressant can be obtained by stirring well.

Abstract

The invention discloses a magnetic dust suppressant. The magnetic dust suppressant comprises 0.5-1wt% of a hydrogel type high-molecular polymer, 0.5-1wt% of epoxy resin, 0.2-0.5wt% of acetamide, 0.05-0.1wt% of sodium stearate, 5-10wt% of magnetic nano-particles and 87.4-93.75wt% of deionized water, and the magnetic nanoparticles are added to make the dust suppressant have strong metal mining powder adsorption ability and keep a long-time stable effect. A nonwoven fabric is laid on the surface of a road, so a dust suppressant film on the surface of the road is protected, and the contact area of the surface of the nonwoven fabric and dusts is increased, thereby the dust suppression effect is further improved.

Description

Technical field [0001] The invention relates to the field of dust suppressants, in particular to a magnetic dust suppressant, a preparation method thereof and a metal mineral dust suppression method. Background technique [0002] Iron ore is an important raw material for steel production enterprises, and the road transportation of iron ore powder is necessary to ensure the harmonious and stable development of national steel enterprises. In the mine, the road surface is often bumpy, coupled with the action of wind, the mineral powder on the surface of the transport truck is scattered on the ground, resulting in dust pollution, the concentration of mineral powder may even reach a suffocating degree, and the visibility is extremely reduced. This not only caused economic losses to related enterprises and units, but also caused serious pollution to the environment along the route and severely affected the production and life of surrounding residents. The current solution is to sprink...
