Novel environment-friendly road surface dust suppressant

Abstract

The invention belongs to the field of dust suppressant, and in particular relates to a novel environment-friendly road surface dust suppressant of which the raw materials consist of 4-6 parts of base oil, 93.5-95.5 parts of water and 0.1-1.0 part of surfactant by weight. The raw materials of the dust suppressant have the organic cooperation and synergistic effect, so that a road surface is kept wet and dust can be adhered, the effective dust suppression time is long, that is, more than 15 days, and the dust suppression efficiency is more than 80%; along with the increase of the times that the dust suppressant is sprayed on the road surface, the dust and grits thrown from vehicles on the road surface can be adhered together to be formed into stable soil, and a layer of oil film is formed on the road surface, so that the function or maintaining and protecting a road is achieved; the application range is wide, that is, except for being used for suppressing dust on roads of strip mines, the dust suppressant can also be widely applied to dust suppression in fields such as urban road construction, refuse dump, tailings warehouses, bulk material fields and the like; and the raw materials are wide in resource, the price is low, the preparation method is simple, convenient and easy to carry out, and therefore, the dust suppressant is applicable to large-scale popularization and application.

Description

technical field [0001] The invention belongs to the field of dust suppressants, and in particular relates to a novel environment-friendly road surface dust suppressant whose raw materials contain base oil, water and surfactants. Background technique [0002] Highway is the main artery of open-pit mine production. The environmental assessment of air quality in open-pit mines at home and abroad agrees that when vehicles transport ore rocks, road driving dust is often the largest source of dust pollution in the mine, and it is the main source of air pollution in open-pit mines. . [0003] Open-pit mine roads are generally earth-stone or gravel temporary roads, with low construction standards, poor engineering quality, and insufficient daily maintenance. Whenever a car is running, dust is everywhere, and the dust content in every cubic meter of air is as high as hundreds of milligrams, causing serious dust pollution. Dust on the road surface can not only endanger human health ...

AI Technical Summary

Problems solved by technology

[0003] Open-pit mine roads are generally earth-stone or gravel temporary roads, the road construction standards are low, the engineering quality is poor, and daily maintenance is not enough

Whenever the car is running, the dust is filled, and the dust content in the air per cubic meter is as high as hundreds of milligrams, causing serious dust pollution

Dust on the road surface can not only endanger human health and destroy the natural environment, make plants die, but also affect the driver's sight, reduce the speed of the truck and increase the distance between two trucks, increase the transportation time, and reduce the transportation efficiency; at the same time, the truck After the cylinder inhales the air with high dust content for a long time, the wear of the cylinder will increase and the fuel consumption will increase greatly, which will directly affect the engine overhaul period and transportation cost of the car; Debris is scattered along the road, road conditions are deteriorating, car tires are severely worn, and vehicle maintenance costs will be greatly increased

[0004] The traditional road dust control method is to use sprinklers to sprinkle water, that is, wet dust removal method, but the water evaporates and penetrates quickly on the dry soil road surface in high temperature summer, so that it cannot effectively prevent dust

And in the open-pit mine transportation road site, it is difficult to do frequent watering operations, and frequent watering operations will cause greater damage to the low-grade road surface, thereby increasing the wear of car tires and shortening the life of the car

Another road dust prevention method is to directly lay high-grade cement or asphalt pavement, but because a large amount of gravel and soil will inevitably be scattered during the process of trucks moving ore rocks, road dust still exists; moreover, in economic and technical It is not allowed to lay high-grade roads in open pits
