Embodiment 1

[0028] Take 0.6g of water-based epoxy resin (solid content 49-51%) (commercially available) and dissolve it in 98.33g of tap water. After fully dissolving, take 0.2g of acetamide and dissolve in the above solution, and then dissolve 0.8g of polyvinyl alcohol in In the above solution, 0.07 g of sodium stearate was dissolved in the above solution, and the mixture was fully stirred evenly to obtain a polymer film dust suppressant with a network structure.

Embodiment 2

[0030] Take 0.9g of water-based epoxy resin (solid content 55-56%) (commercially available) and dissolve it in 97.71g of tap water. After fully dissolving, take 0.3g of acetamide and dissolve it in the above solution, then dissolve 1.0g of polyacrylic acid in the above solution, and then 0.09g of sodium stearate was dissolved in the above solution, and fully stirred evenly to obtain a network structure polymer film dust suppressant.

Embodiment 3

[0032] Take 1.0g of water-based epoxy resin (solid content 50%) (commercially available) and dissolve it in 97.9g of tap water. After fully dissolving, take 0.5g of acetamide and dissolve it in the above solution, then dissolve 0.5g of polyvinylpyrrolidone in the above solution, and then dissolve 0.1g of sodium stearate in the above solution, fully stir evenly, and then obtain the polymer film dust suppressant with network structure.

Abstract

The invention relates to a high molecular thin film dust suppressant in a netty structure and a preparation method thereof. The dust suppressant comprises the following components in percentage by weight: 0.5-1.0% of hydrogel high molecular polymer, 0.5-1.0% of epoxy resin, 0.2-0.5% of acetamide, 0.05-0.1% of acetamide and 97.4-98.75% of water. The dust suppressant provided by the invention can be proportioned in a normal temperature state without adding other warming equipment. The dust suppressant proportioned at the normal temperature is sprayed or coated on the surface of mineral powder of a carriage, so that a protective layer is formed on the surface of the mineral powder, thereby avoiding flowing dust pollution of the mineral powder along the line and flowing dust damage of the mineral powder in the railway transportation process. Furthermore, the environmental pollution is avoided, and both huge economic benefit and social benefit of environmental conservation are obtained for railway transportation and mineral powder clients.

Description

technical field [0001] The invention relates to a polymer film dust suppressant with a network structure and a preparation method thereof. The dust suppressant is mainly used for preventing mineral powder loss and environmental pollution during transportation and stacking of coal and other mineral powder materials. Background technique [0002] At this stage, China's coal and common mineral powder are generally transported by open car in railway transportation. During the transportation process, due to the bumps caused by the roadbed, turnout and track facilities, coupled with the wind force, especially when the train enters the tunnel, due to the "piston wind" effect, it will form an instant strong disturbance air flow, and the fine mineral powder on the surface will The particles are blown away from the vehicle body, fall onto the road surface, and then be rolled by subsequent vehicles to form secondary dust with smaller particle size and higher concentration. As a result...
