Abstract
The invention discloses a kind of dust suppressant, which contains semi-synthetic high molecular material, aqueous epoxy resins, curing agent and moisturizer；Relative to the semi-synthetic high molecular material of 1 parts by weight, the content of aqueous epoxy resins is 0.5 2 parts by weight, and the content of curing agent is 0.02 0.08 parts by weight, and the content of moisturizer is 0.2 0.75 parts by weight.When the dust suppressant of the present invention is sprayed onto coal surface, the water-soluble components such as semi-synthetic high molecular material therein can play the role of adhering to coal particles, curable aqueous epoxy resins component can be formed in coal surface particles with certain thickness cured layer, so as to improve the dust-proof effect of dust suppressant.The dust suppressant of the present invention has the advantages that raw material components are derived from a wealth of sources, prepared and easy to use and at low cost simultaneously.
Description
Technical field
The present invention relates to environmental technology fields, and in particular, to a kind of dust suppressant and its preparation method and application and suppression
The method of Coal Transport airborne dust processed.
Background technology
It is shown according to national statistics data, with the development of national economy and the progress of science and technology, China's raw coal output exists
1998 are 12.50 hundred million tons, by " gold 10 years " sustainable growth of coal, reach record-breaking to raw coal output in 2014
38.7 hundred million tons, close to the 50% of current year world's output of coal, become maximum in the world coal producer and country of consumption.Particularly undergo coal
Between the gold decade in charcoal market, coal demand is substantially improved, with the national maximum eastern coal of mining listed corporations Shenhua god
For group, 2.1 hundred million tons of the coal volume of production and marketing of 2013,20,000,000 tons of volume of production and marketing increases nearly more than 10 times during compared with 2003.Such as
Coal more than this is passed through to be come out from underground mining, has sub-fraction to convert or sent through highway, waterway transportation channel on the spot, and exhausted
It is most of all to have selected to be transported by the railway of economical and efficient.
In order to meet market transport power demand, freight-transport capacity is promoted, railway parent company for several times in China arranges shipping
Vehicle improves the speed of service.By the coal of railway transportation after each website entrucking, in train is run at high speed because itself speed, from
The reasons such as right wind-force, cause the tiny coal particle at the top of wagon to come off, and trickle down Along Railway；Especially train passes through at a high speed
Because the change of instantaneous pressure difference, it is even more serious to trickle down situation for coal grain in tunnel during Tunnel body.The coal that Tunnel body is trickled down
There are the quick-fried security risks of dirt after grain or coal dust largely gather, and threaten traffic safety.Coal is led in train in transit unrestrained
Transport loss increase, environmental improvement difficulty is caused to increase, tunnel driving security risk raising.
This problem is trickled down for existing coal charge surface layer little particle during solving railway transportation coal, both at home and abroad more enterprises
Industry releases the dust suppressant that various models, type are various, composition is different.But existing dust suppressant to coal long-distance transportation when
Anti-dust effect is not ideal enough, while also there are the shortcomings that raw material sources are not extensive, production cost is high.
Invention content
The object of the present invention is to provide a kind of dust suppressant, it is long to coal which can solve dust suppressant in the prior art
During distance transport anti-dust effect is undesirable and raw material sources not extensively, the technical issues of production cost is high.
To achieve these goals, the present invention provides a kind of dust suppressant, which contains semi-synthetic high molecular material, water
Property epoxy resin, curing agent and moisturizer；Relative to the semi-synthetic high molecular material of 1 parts by weight, the content of aqueous epoxy resins is
0.5-2 parts by weight, the content of curing agent is 0.02-0.08 parts by weight, and the content of moisturizer is 0.2-0.75 parts by weight.
The present invention also provides a kind of method for inhibiting Coal Transport airborne dust, this method includes：It is sprayed in coal deposition surface
Above-mentioned dust suppressant, wherein, relative to the deposition surface of every square metre of coal, the fountain height of the dust suppressant is 1.3-3kg.
Through the above technical solutions, the present invention uses semi-synthetic high molecular material and aqueous epoxy resins as dust suppressant
