Abstract
The present invention relates to a dust inhibition agent for inhibiting dust suspension. The dust inhibition agent comprises, by weight, 50-90 parts of water, 2-30 parts of polyvinyl alcohol, 1-20 parts of polysaccharide, 0.5-5 parts of a surfactant, and 0.1-3 parts of sodium benzoate, wherein the dust inhibition agent has characteristics of no toxicity, no harm, biodegradability and no secondary pollution. During a use process, the diluted dust inhibition agent is sprayed on sand soil heap, ash heap, road surface and the like, provides effects of wetting, adhesion, condensation, moisture absorption, dust resistance, etching resistance and erosion resistance through capturing, absorbing and aggregating dust micro-particles, and forms a layer of an adhesive film with a network structure on the surface so as to effectively fix dust and form a protection film on the surface of the material, such that the dust is fixed, dust re-suspension is inhibited, material loss can be effectively reduced, dust pollution is reduced, the environment is protected, and health of workers and the surrounding population are protected.
Description
Technical field
The invention belongs to the dust-inhibitor field, especially a kind of for suppressing dust-inhibitor that dust suspends and preparation method thereof.
Background technology
Chinese society, economy are in all-round developing period, and in the economic construction activity, because of building operation, stock ground accumulation, material transportation, road dust, and the dust pollution that waste ash pond, mineral products stacking, Coal Transport etc. cause is more and more serious.At present, China city pellet is empty learns the suspended particulate that the aerodynamic force diameter is less than 10 μ m has become principal pollutant, and these and airborne dust are closely related.
At present, the earthwork in architectural process, sand material are piled up, and widely used is dust suppression cloth, and neither environmental protection is also uneconomical, and waste is serious, and effect is also general.Many low-cost roads, the road surface situation is poor, and airborne dust is large, also very large to environmental hazard.Heavy truck produces very many dust in transportation, all very harmful to ecotope and Working environment.Traditional watering method, during the broiling summer, especially northern, the moisture evaporation is fast, after the moisture evaporation, can lose effect, need to frequently sprinkle water, and can cause huge waste and the expense expenditure of water resources.More existing dust-inhibitors, can not meet actual needs, as the glycerol class, can suppress slight floating dust to a certain extent, and the dirt effect is less admittedly for the mound larger for dust quantity.Some styrenic materials of using, the dust suppression effect is remarkable, but environmental toxicity is larger.Therefore, efficient, the environmental protection of development, the dust-inhibitor economized on resources will have very important Social benefit and economic benefit.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of dust-inhibitor suspended for suppressing dust be provided, this dust-inhibitor toxicological harmless, biodegradable, can not cause secondary pollution, can be effectively fixing dust form protective film on the material surface.
It is a kind of for suppressing the preparation method of the dust-inhibitor that dust suspends that another object of the present invention is to provide.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of dust-inhibitor suspended for suppressing dust, the component of its dust-inhibitor and ratio of weight and number thereof are:
And the component of this dust-inhibitor and optimum ratio of weight and number thereof are:
And described polysaccharide is the wherein a kind of of carboxymethyl cellulose, carboxyethyl cellulose, Xylo-Mucine, sodium hydroxyethlcellulose, methylcellulose gum, sodium carboxymethylcellulose pyce or starch.
And described tensio-active agent is the wherein a kind of of sodium laurylsulfonate, Sodium dodecylbenzene sulfonate, sodium lauryl sulphate, tetradecyl benzene sulfonic acid sodium salt or pentadecyl benzene sulfonic acid sodium salt.
A kind of for suppressing the preparation method of the dust-inhibitor that dust suspends, its method for first adding water according to ratio of weight and number in reactor, be heated to 50～90 ℃, then slowly add respectively polyvinyl alcohol, polysaccharide, tensio-active agent, Sodium Benzoate, be heated with stirring to fully and dissolve, mix, be incubated after 10～40 minutes, obtain the finished product of the dust-inhibitor for suppressing the dust suspension.
And most preferably the water Heating temperature is 60～80 ℃; Most preferably soaking time is 15～30 minutes.
Advantage of the present invention and beneficial effect are:
The dust-inhibitor toxicological harmless that this suspends for suppressing dust, biodegradable, can not cause secondary pollution, after use procedure dilution, be sprayed at above sandy soil heap, dust heap, road surface etc., by seizure, absorption, reunion dust particle, play moistening, bonding, condense, the effect of moisture absorption, dustproof, anti-etch and antiscour, form the cancellated adhesive film of one deck on its surface, can be effectively fixing dust form protective film on the material surface, thereby dust is fixed, suppress it and suspend again.Can effectively reduce and reduce material loss, reduce dust pollution, protection of the environment, protection workman and peripheral crowd's is healthy.
