Description

Dust suppressant and the method for suppression Coal Transport airborne dust
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.
Summary of the invention
It is an object of the invention to provide a kind of dust suppressant, this dust suppressant can solve dust suppressant in prior art Undesirable to anti-dust effect during coal long-distance transportation, and raw material sources are extensive, production cost is high Technical problem.
To achieve these goals, the present invention provides a kind of dust suppressant, and this dust suppressant contains semi-synthetic high score Sub-material, aqueous epoxy resins, firming agent and wetting agent;Relative to 1 weight portion semi-synthetic macromolecule material Material, the content of aqueous epoxy resins is 0.5-2 weight portion, and the content of firming agent is 0.02-0.08 weight portion, The content of wetting agent is 0.2-0.75 weight portion.
The present invention also provides for a kind of method suppressing Coal Transport airborne dust, and the method includes: pile up at coal The above-mentioned dust suppressant of surface sprinkling, wherein, relative to the deposition surface of every square metre of coal, described dust suppressant Fountain height be 1.3-3kg.
By technique scheme, the present invention uses semi-synthetic macromolecular material and aqueous epoxy resins conduct The main component of dust suppressant, when dust suppressant is sprayed onto coal surface, semi-synthetic macromolecular material therein Can play the effect adhering to coal particles Deng water-soluble component, curable aqueous epoxy resins component can To be formed in coal surface particles, there is certain thickness cured layer, thus improve the dust-proof effect of dust suppressant Really.The dust suppressant of the present invention has raw material components wide material sources, preparation and easy to use and low cost simultaneously Advantage.
Other features and advantages of the present invention will be described in detail in detailed description of the invention part subsequently.
