Abstract
The invention discloses a road dust inhibitor and a preparation method thereof. The road dust inhibitor is characterized in that the raw materials of the road dust inhibitor comprises surface active agents, stabilizers, hydrophilic agents, thickeners, anti-freezing auxiliaries, antibacterial agents and water. The preparation method comprises, firstly, adding an appropriate amount of water into a reactor; secondly, adding the surface active agents and the stabilizers in; thirdly, after the surface active agents and the stabilizers are fully dissolved, slowly adding the hydrophilic agents and the thickeners in and stirring to achieve dissolution; fourthly, adding the anti-freezing auxiliaries and the antibacterial agents in; lastly, adding the residue water in until reaching a designated concentration. By means of the surface active agent, the road dust inhibitor can form a layer of isolating film on the contact surface between dust and air, and the isolating film has high water carry capacities and adhesive performance; by adding a small amount of salt, the road dust inhibitor obtain certain anti-freezing and antibacterial effects.
Description
Technical field
The invention belongs to field of environment protection, relate to a kind of dust-inhibitor, particularly a kind of dust on the roads dust-inhibitor and preparation method thereof.
Background technology
At present, China's Air quality causes anxiety, and haze, PM2.5 make people hard to guard against, has a strong impact on the life of people and healthy.Trace sth. to its source, pollutant sources has number of ways.Major part North City Air Pollutants is pellet.Particulate pollutant mainly comes from working-yard, dumping and dust on the roads etc.Solid accumulation in construction site is outdoor mostly, and through exposing to the weather, the surperficial refinement of bank, easily enters in air and form particulate pollutant.So working-yard and scrap heap etc. stack the main source that material is city raised dust.Airborne dust particulate matter enters into air, and slowly precipitating falls earthward, and road vehicle travels and airborne dust is got back in air.Road becomes secondary pollution source, and harm can not be ignored.
Airborne dust particulate matter component is complicated, is not single material composition, is mainly made up of coal dust and fine dirt etc.Most particulate pollutant has certain wetting ability or hydrophobicity.Domestic and international most chemical Fugitive dust inhibiting agent, its composition mainly has the tensio-active agent of moistening water-retentivity, the sticking macromolecular organic compound of tool and there is hygroscopic inorganic salts, this kind of dust-inhibitor often function singleness, only consider hydrophobicity and the wetting ability aspect of particulate matter, do not reach ideal effect.
Summary of the invention
The present invention is for solving the undesirable problem of existing Fugitive dust inhibiting agent effect, is intended to there are provided a kind of compound dust on the roads inhibitor and preparation method thereof, to expect to make it have good inhibition.
The object of the invention is to realize by following technical solution:
In dust on the roads inhibitor of the present invention, the proportioning of each raw material percentage composition is by weight:
Tensio-active agent 10%-15%;
Stablizer 10%-15%;
Hydrophilizing agent 5%-10%;
Thickening material 5%-10%;
Antifreeze auxiliary agent 5%-10%;
Fungistat 5%-10%;
Water 30%-60%.
Further, in dust on the roads inhibitor of the present invention:
Described tensio-active agent is the mixture of one or more in APG, sodium alginate, plant sterol and tea saponin.
Described stablizer is one or both the mixture in polyoxyethylene glycol and polyvinyl alcohol.
Described hydrophilizing agent is one or both the mixture in sucrose and water soluble starch.
Described thickening material is the mixture of one or more in water glass, Natvosol and Walocel MT 20.000PV.
Described antifreeze auxiliary agent is the mixture of one or more in calcium chloride, sodium-chlor and Repone K.
Described fungistat is Sodium Benzoate.
Accordingly, the present invention furthermore present the preparation method of described dust on the roads inhibitor, its feature is: the water first adding appropriate amount in reactor, add tensio-active agent and stablizer again, slowly hydrophilizing agent and thickening material is added and stirring and dissolving after tensio-active agent and stablizer fully dissolve, finally add antifreeze auxiliary agent and fungistat, then add remaining water, obtain road Fugitive dust inhibiting agent.
Dust on the roads inhibitor of the present invention has moistening function, attachment function, but also form one deck barrier film at dust and air contact surfaces, barrier film has good takes water-based and tackiness, and makes Fugitive dust inhibiting agent have certain antifreeze and bacteriostatic action by adding of a small amount of salt.
During onsite application, dust on the roads inhibitor of the present invention and water are pressed 50-500 to dilute, then inject spraying vehicle, spray to highway by normal fountain height.
Beneficial effect of the present invention is embodied in:
1, dust on the roads inhibitor of the present invention has moistening, cohesive action, can not only effectively suppress airborne dust to fly upward, and forms one deck preferably have the slime layer of certain thickness and intensity on airborne dust surface, and can this state of maintenance of long period;
2, nontoxic, harmless, the health environment-friendly of dust on the roads inhibitor of the present invention, can not generate new pollutent and degradable;
3, dust on the roads inhibitor of the present invention freely can allocate Dilution ratio according to the different situations such as site wind, wetness;
4, dust on the roads inhibitor of the present invention has more satisfactory effect equally to the airborne dust such as coal and scrap heap Particulate Pollution source.
Embodiment
Below by embodiment, the present invention is described in further details.But described example is not construed as limiting the invention.
The preparation method of dust on the roads inhibitor of the present invention, carries out as follows:
