Abstract
The invention provides an anti-oxidation dust suppressant and a preparation method thereof. The anti-oxidation dust suppressant comprises components according to the following parts by weight: 20-40 parts of alkyd resin, 5-15 parts of triethylene glycol momobutyl ether, 5-10 parts of trimethylolpropane and 40-60 parts of water. The preparation method of the anti-oxidation dust suppressant comprises the following steps: according to the parts by weight, taking the water soluble alkyd resin, sequentially adding water, triethylene glycol momobutyl ether and trimethylolpropane, and uniformly stirring to obtain the anti-oxidation dust suppressant. The anti-oxidation dust suppressant has the beneficial effects that the defects of short maintaining time, poor effect, great loss of fuel value, blocking of a conveying system and the like in dust removal by purely watering are overcome, quick surface drying can be realized one hour after spraying, curing and crusting can be realized in a short time so as not to delay the operating time, and the anti-oxidation dust suppressant is long in dust suppression lasting time and good in effect. Meanwhile, the anti-oxidation dust suppressant also has the advantages of quick drying property, high water resistance, wind resistance, oxygen barrier property, acid and alkali resistance and the like.
Description
Technical field
The invention belongs to environment protection and improvement field, the concrete a kind of antioxygen dust-inhibitor and preparation method thereof that relates to.
Background technology
In a lot of petrochemical enterprises or electric power enterprise, coal remains a kind of important fuel.General coal all is open-air accumulating, the problem of bringing: be blown to four winds easily on the one hand, fly upward everywhere, cause the pollution of environment, the waste of material; On the other hand, because dust from flying is deposited on pipeline, cable etc. and locates, cause spontaneous combustion easily and initiation fire; And the piece grain is scattered, and also easily vehicular traffic caused potential safety hazard.This problem is not the coal heap, and some other powder or blocky solid accumulation also can cause same hidden danger.
Existing treatment process generally is watering or covers that the shortcoming of existence is: cover waste of manpower, inefficiency; Watering then needs constantly to spray, and moisture one is dried, then still can produce a large amount of dust, and effect is relatively poor.
Along with the Recent study development, also there are a lot of dust-inhibitors to emerge.For example application number is that 201010180552.7 Chinese patent discloses a kind of dust-inhibitor and method of use thereof, uses starch 3-5 part, water 35-40 part; Vinylformic acid 15-20 part; 30% sodium hydroxide 30-40 part, initiator 8-12 part, linking agent 1-5 part is prepared from through corresponding steps.Application number is that 200910265220.6 patent discloses a kind of coal dust depressor and preparation method thereof, and concrete technical scheme is: sodium lignosulfonate 20%-30%, vinylformic acid 12%-18%; Ydrogen peroxide 50 0.4%-0.6%, quicklime 5%, sodium tetraborate 0.5%; Sodium methyl silicate 0.3%; Water 43%-59% according to different interpolation order, and controls different temperature of reaction and the time prepares.
The deficiency of above-mentioned two kinds of dust-inhibitors is: component is complicated, and preparation process is loaded down with trivial details, and anti-dust effect is not ideal enough, and function ratio is more single; Be difficult to change greatly or maintenance anti-dust effect under other extreme cases in potential of hydrogen.
Summary of the invention
The purpose of this invention is to provide a kind of antioxygen dust-inhibitor and preparation method thereof.The dust that can be widely used in factories and miness storing heaps such as power station, harbour, the improvement of harbour flying dust and steel mill, coke-oven plant, cement mill suppresses the field._
For realizing above-mentioned goal of the invention, technical scheme of the present invention is following:
A kind of antioxygen dust-inhibitor comprises the component of following weight part:
The preparation method of this dust-inhibitor is: according to above-mentioned massfraction, water intaking dissolubility Synolac adds entry, triethylene glycol butyl ether and TriMethylolPropane(TMP) successively, and stirring promptly gets.
Water soluble alkyd resin of the present invention is to adopt medium oil alkyd, adds benzoyl peroxide (BPO), acrylic amide, hydroxyethyl meth acrylate, NSC 20956 and YLENE; Under protection of inert gas, 100 ℃ were reacted 2 hours, and were chilled to room temperature; Steam YLENE; Generate acrylic acid modified alkyd resin, add butyl glycol ether, the water soluble alkyd resin that modification becomes.
Said medium oil alkyd is available from the Shandong refined chemical industry of precious youngster ltd, and article No. is 355-1, and concentration is 55%.
Other materials is common industrial chemicals, can buy gained by market.
Triethylene glycol butyl ether has another name called: triglycol monobutyl ether, triethylene glycol butyl ether; TriMethylolPropane(TMP), chemical name are 2-ethyl-2-methylol-1, ammediol; Have another name called trihydroxymethyl propane, 2,2-dihydroxymethyl butanols, above-mentioned two kinds of raw materials all can be buied by market.
The invention has the beneficial effects as follows: solved simple watering dedusting hold time weak point, weak effect, in a large number lose fuel value, stop up defectives such as delivery system, the dust suppression longer duration, effective.Also have following advantage simultaneously:
1) quick-drying: one hour quick surface drying after environmental protection antioxygen dust-inhibitor sprays, solidify crust in the short period of time, can not delay the activity duration.
2) enhanced water resistance: environmental protection antioxygen dust-inhibitor can impact by anti-rainwater, prevents that rainwater from pouring the coal stock pile and causing spontaneous combustion and reduce fuel value, prevents that also rainwater from getting into the deep oxidation that the powdered iron ore stock pile causes iron ore.
3) wind resistance: after the film forming, sealing membrane is fixed stock pile, and 8 grades of strong wind of actual test can airborne dust yet, reaches the effect of environmental protection dust suppression fully.
4) oxygen barrier property: sealing membrane can stop oxygen to get into, and avoids the oxidation of coal and iron powder, has practiced thrift a large amount of coals and iron ore deposit, has avoided the waste of resource.
5) resistance to acids and bases: product of the present invention is acidproof, is not afraid of acid rain and washes away; This product is also alkaline-resisting, can be sprayed on the lime stock pile, has enlarged use range.
Embodiment
Below principle of the present invention and characteristic are described, institute gives an actual example and only is used to explain the present invention, is not to be used to limit scope of the present invention.
Preparing method: in reaction kettle, add water soluble alkyd resin 300Kg, add 550Kg water, stir, add the 100Kg triethylene glycol butyl ether again and the 50Kg TriMethylolPropane(TMP) stirs, discharging.
Concrete application effect is: during use, the product of directly getting system sprays and gets final product.Also can be according to practical situation, an amount of thin up.The quick surface drying of 30min after this antioxygen dust-inhibitor sprays, but can not crust.Experiment place fresh gale still airborne dust can not occur.
Preparing method: in reaction kettle, add water soluble alkyd resin 200Kg, add 400Kg water, stir, add the 50Kg triethylene glycol butyl ether again and the 50Kg TriMethylolPropane(TMP) stirs, discharging.
Preparing method: in reaction kettle, add water soluble alkyd resin 400Kg, add 600Kg water, stir, add the 150Kg triethylene glycol butyl ether again and the 100Kg TriMethylolPropane(TMP) stirs, discharging.
The above is merely preferred embodiment of the present invention, is not limited to the present invention, and is all within spirit of the present invention and principle, and any modification of being made and be equal to replacement all should be included within protection scope of the present invention.
