Abstract
The invention discloses a dust suppression agent. The dust suppression agent contains a semi-synthesized polymer material, waterborne epoxy resin, a curing agent and a moisturizing agent. Relative to 1 part by weight of the semi-synthesized polymer material, the content of the waterborne epoxy resin is 0.5-2 parts by weight, the content of the curing agent is 0.02-0.08 part by weight, and the content of the moisturizing agent is 0.2-0.75 part by weight. When the dust suppression agent is sprayed on the surfaces of coals, the semi-synthesized polymer material and other water-soluble components can play the effect of adhering coal particles, the curable waterborne epoxy resin component can form a curing layer having a certain thickness on coal surface particles, and accordingly the dust prevention effect of the dust suppression agent is improved. In addition, the dust suppression agent has the advantages of being wide in raw material component source, convenient to prepare and use and low in cost.
Description
Technical field
The present invention relates to environmental technology field, in particular it relates to a kind of dust suppressant and preparation method thereof and should
With and suppression Coal Transport airborne dust method.
Background technology
Showing according to national statistics data, along with development and the progress of science and technology of national economy, China is former
Output of coal was 12.50 hundred million tons in 1998, through " gold 10 years " sustainable growth of coal, to 2014
Year raw coal output reaches record-breaking 38.7 hundred million tons, close to the 50% of world's output of coal then, becomes generation
Coal producer maximum in boundary and country of consumption.Particularly experiencing between the gold decade of coal market, coal needs
The amount of asking is substantially improved, as a example by the mining listed corporations Shenhua god east coal group that the whole nation is maximum, and 2013
The coal volume of production and marketing 2.1 hundred million tons in year, during compared with 2003, volume of production and marketing 20,000,000 tons increases nearly more than 10 times.
So many coal, through from underground mining out, has sub-fraction to convert on the spot, or through highway, water route fortune
Defeated channel sends, and the railway that the overwhelming majority all have selected by economical and efficient transports.
In order to meet market transport power demand, promoting freight-transport capacity, railway head office is the most in China
Goods train is improved the speed of service.By the coal of railway transportation after each website entrucking, high at train
Because of self reason such as speed, natural wind in speed traveling, the tiny coal particle at wagon top is caused to take off
Fall, unrestrained Along Railway；Especially train at a high speed by during Tunnel body because the change of instantaneous pressure difference,
In tunnel, to trickle down situation even more serious for coal grain.Coal grain that Tunnel body is unrestrained or coal dust are deposited after gathering in a large number
In the security risk that dirt is quick-fried, threaten traffic safety.Coal, at train in transit unrestrained, causes transport
Loss increases, environmental improvement difficulty strengthens, tunnel driving security risk raises.
This difficult problem is trickled down for solving the little granule in coal charge top layer present in railway transportation coal process, domestic
Outer many enterprises release various models, of a great variety, form different dust suppressant.But existing dust suppression
Agent is not ideal enough to anti-dust effect during coal long-distance transportation, there is also simultaneously raw material sources not extensively,
The shortcoming that production cost is high.
