Description
Technical field
The present invention relates to a kind of synthetic method of utilizing a kind of waste and old polystyrene plastics synthesizing high-hydroscopicity resin.
Background technology
The exploitation of super absorbent resin has only the history of decades, abroad from sixties research and development.Just there has been first patent in China at just synthetic first super absorbent resin of nineteen eighty-two by 1988.The kind of super absorbent resin is a lot, by sources divide mainly contain starch system, cellulose-based and synthetic resins is three major types.The product performance of these method gained are all better, but the raw material that is adopted all is regular Industrial products, and cost is higher.The domestic technology of waste resource synthesizing high-hydroscopicity resin of utilizing is also few at present.Through CNKI, incomparably database, tie up general database, the emerging figure full-text database of gold newspaper, in through data base queryings such as private network and Chinese patent nets, there is no with the polystyrene foamed plastics is the similar work that raw material comes synthesizing high-hydroscopicity resin.
Polystyrene foamed plastics is because of its light weight, low price and firm and be widely used in the packing of household electrical appliance, instrument, special process product and snack food product.Along with its consumption of expanding economy is increasing.Can not degrade voluntarily in physical environment because of it again, so not only cause serious white pollution, and cause the significant wastage of resource.
Summary of the invention
The object of the present invention is to provide a kind of polystyrene foamed plastics and acrylate graft-blending synthesizing high-hydroscopicity resin of utilizing.Make the depleted porous plastics obtain appropriate recovery and reuse on the one hand, turn waste into wealth; Also can reduce the manufacturing cost of super absorbent resin on the other hand, strengthen competitiveness of product.
Present method is to adopt mixed solvent elder generation dissolved polystyrene, carries out graft copolymerization with acrylate then in the presence of initiator, dispersion agent, coupling agent, linking agent.
Processing step is as follows:
Sodium acrylate is dissolved in an amount of water,
Use the mixed solvent dissolved polystyrene,
Above two kinds of solution are mixed,
Add initiator, dispersion agent, coupling agent, linking agent, emulsification pretreatment in water-bath,
60～80 ℃ of fully reactions under protective atmosphere,
Be solidified into super absorbent resin at 110～130 ℃.
Raw materials used ratio is (WT%) in the above technology:
Sodium acrylate 50～95.5%
Polystyrene 2.5～47%
Dispersion agent 1.5～3%
Coupling agent 0.07～0.4%
Initiator 0.1～0.5%
Linking agent 0.05～0.6%.
Here said an amount of water is meant: the water (hypervolia can increase the steam output in the subsequent technique) that is enough to dissolve sodium acrylate; Said mixed solvent is meant that two or more traditional organic solvent mixes the solvent that constitutes, for example mixed solvent that is made of ethyl acetate, toluene, hexanaphthene or ethyl acetate, toluene, pimelinketone.Said initiator can be the combination of ammonium persulphate and sodium bisulfite, or the combination of hydrogen peroxide and sodium bisulfite; Dispersion agent can be: Si Ban-60 or Sodium dodecylbenzene sulfonate; Coupling agent can be: Diisopropyl azodicarboxylate or Polyethylene Glycol-600; Linking agent can be the ethanolic soln or the glycerine of epoxy chloropropane.Said protective atmosphere is nonoxidizing atmosphere or inert atmosphere, for example nitrogen, carbon dioxide gas etc., specifically following prescription of recommendation and technology:
Raw material (WT%)
Sodium acrylate 94.1～50.9%
Polystyrene 3.4～45.2%
Si Ban-60 2.18～2.90%
Diisopropyl azodicarboxylate 0.03～0.3%
Ammonium persulphate 0.09～0.3%
Sodium bisulfite 0.06～0.1%
Epoxy chloropropane 0.1～0.3%
Synthesis technique: at first in reaction vessel, add an amount of water and sodium acrylate, stir with magnetic.The mixed solvent of forming with ethyl acetate, toluene, hexanaphthene (volume ratio is about: 15: 19: 5) dissolves the washes clean polystyrene foamed plastics.Above two kinds of solution are mixed, add initiator, dispersion agent, coupling agent, linking agent, shear half an hour 30 ℃ water-bath high speeds.About three hours of 70 ℃ of reactions under the protection of logical nitrogen then.Last 120 ℃ are solidified into super absorbent resin.
Water-absorbent is measured: take by weighing a certain amount of dried resin, be immersed in the deionized water to volume not variation basically.With the unnecessary moisture content of 100 eye mesh screen eliminations, claim that again the resin after the suction is heavy, be calculated as follows:
Water-intake rate (g/g)=(heavy (the g)-dried resin of the resin after the suction heavy (g))/dried resin heavy (g)
The present invention has following characteristics compared with prior art:
1, on the prescription being is main raw material with waste old polystyrene foamed plastic and sodium acrylate.Inhaling the deionized water rate is 100～1000g/g, and the ability of suction deionized water is suitable with the water-retaining capacity of other pure substance synthetic absorbent resin, and some may surpass its water regain.
2, synthetic process using reversed emulsion polymerization.Product is a copolymer, and technology is simple, is convenient to control.The time of polyreaction is short, the efficient height.
3. the waste old polystyrene foamed plastic one by one of the main synthetic materials among the present invention is the main thing of white pollution, and polystyrene fuel very easily.The product that can synthesize does not then have fuel, and reaction process is also safe and harmless.So just make these gurrys obtain appropriate utilization again, therefore can produce good economic benefit and environmental benefit with junk of fire hazard.
