Abstract
The invention discloses a dust preventing agent, which includes components of water or deionized water, acrylic acid, methacrylate, acrylamide and initiator, wherein proportion of each component is: 90-120 quotient of water or deionized water; 7-12 quotient of acrylic acid or 2-4 quotient of methyl methacrylate, ethyl methacrylate or propyl methacrylate; 2-4 quotient of acrylamide; 0.05-0.1 quotient of persulfate initiator; 0.03-0.05 quotient of crosslinking agent and 5-10 quotient of neutralizer which are also added. The dust preventing agent is thick liquid and is used after diluting, when being sprayed, the dust preventing agent can adsorb dust in air and combine with granule on ground surface to form film structure, and the dust preventing agent also possesses water-absorbing quality and water-retention property to prevent dust flying and clean air.
Description
Technical field
The invention belongs to a kind of organic dedusting agent field, be specifically related to organic chemical industry's class dust preventing agent and preparation method thereof.
Background technology
Urban construction, all kinds of building field, mining, road construction, garbage loading embeading, industrial residue storage etc. can produce a large amount of dust, these dust granules are easily kicked up by wind and are swum in the air, cause atmospheric pollution, give rise to diseases, therefore the quality of life that has a strong impact on people must adopt an effective measure and be controlled with physically and mentally healthy.At present, the method that prevents of dust mainly contains spray sprinkler depositing dust, fly-ash separator dedusting etc., but all there is tangible limitation in these methods, and spraying and watering and lowering dust are provisional, in case dry air, floor-dust can be kicked up once again; The fly-ash separator dedusting just is used for regional area, is not suitable for the big area dedusting.Research and develop new technology and method and carry out the urgent task that dedusting is the environmentalist.
Summary of the invention
The objective of the invention is:, provide a kind of effective, dust preventing agent that cost is low, nontoxic, pollution-free, easy to use at the deficiency of existing dedusting method.
Technical scheme of the present invention is: dust preventing agent, main component comprise water or deionized water, vinylformic acid, methyl methacrylate, acrylamide.Wherein each set of dispense ratio is:
Water or deionized water 90-120 weight part
Vinylformic acid 7-12 weight part
Methyl methacrylate, ethyl ester or propyl ester 2-4 weight part
Acrylamide 2-4 weight part
Initiator (as persulphate) 0.05-0.1 weight part
The present invention adds in addition:
Linking agent (as quadrol) 0.03-0.05 weight part
Neutralizing agent (as ammoniacal liquor or sodium bicarbonate) 5-10 weight part
Its preparation method is: with deionized water, vinylformic acid, methyl methacrylate, acrylamide and linking agent Hybrid Heating, do not stop to stir, add initiator when being heated to 65-75 ℃, reacted 30-60 minute, the cooling back adds neutralizing agent and transfers to neutrality, obtains described dust preventing agent.
Characteristics of the present invention are: the present invention is viscous liquid, use the dilution back, dust during sprinkling in the energy absorbed air, combine with the fine particle of ground surface, easily form membrane structure, dust granule is played parcel, binding, firm effect, and have certain water-absorbent and water-retentivity, thereby prevent that dust from kicking up, play the effect that purifies air.
The present invention is neutral liquid, has nontoxic, free of contamination advantage, and used water is pressed the arbitrary proportion dilution, easy to use, good dedusting effect is a kind of high performance dust preventing agent, meeting " environmental labelling product technical requirements " basic demand (HJB2004-94), is environmentally friendly product.Cost of the present invention is low, easy to prepare, and is nontoxic, pollution-free, easy to use.
Embodiment
The present invention is mainly used in the airborne dust in places such as preventing all kinds of building fields, road construction, refuse landfill, storage ashpit, army campsite, mining, poisonous hazardous area, the effect of playing dust suppression and purifying air.
With deionized water, vinylformic acid, methyl methacrylate, acrylamide and linking agent Hybrid Heating, do not stop to stir, add initiator when being heated to 65-75 ℃, to react 30-60 minute, the cooling back adds neutralizing agent and transfers to neutrality, obtains described dust preventing agent.Wherein each set of dispense ratio is:
Deionized water 100-120 weight part: all can for 100 or 120 parts; Vinylformic acid 7-12 weight part: 7 or 12 parts all can, or methyl methacrylate 2-4 weight part: 2 or 4; Add acrylamide 2-4 weight part again: all can for 2 or 4 parts; Linking agent 0.03-0.05 weight part all can for 0.03 or 0.05 part; Initiator 0.05-0.1 weight part: 0.05 or 0.1 weight part all can; Neutralizing agent (typical in sodium hydroxide or potassium hydroxide) 5-10 weight part all can for 5 or 10 parts.Used water was diluted by arbitrary proportion when the present invention used.Can adopt as Potassium Persulphate is initiator.Linking agent: one of Resins, epoxy, isocyanic ester, urea resin, quadrol, also can adopt polyvalent metal salt 0.04 weight part.
