Abstract
The invention relates to sodium chloride floatation agent, which is characterized by being prepared by the following raw materials in parts by weight: 1 to 20 parts of polyvinyl alcohol and 80 to 99 parts of water. The invention also discloses a preparation method of the sodium chloride floatation agent. The sodium chloride floatation agent prepared by the method of the invention is a glutinous liquid which is water solution, and the sodium chloride floatation agent has high dispersibility in brine and can be used as a collecting agent directly. The sodium chloride floatation agent has a good floatation effect on sodium chloride; besides, the floatation agent is colorless and odorless, free from corrosivity, safe and convenient to use and low in reagent cost.
Description
Technical field
The present invention relates to a kind of flotation agent and preparation method thereof, particularly a kind of floatating agent of sodium chloride and preparation method thereof; The invention still further relates to the purposes of this floatating agent of sodium chloride.
Background technology
At present domestic is in the production technology of raw material production refined carnallite with the carnallite, and floatating agent of sodium chloride mainly contains two kinds, and a kind of is the N-alkyl morpholine, and a kind of is fatty acid amide.Fatty acid amide is a wax, and it dissolves dispersion effect in water or bittern poor, must adopt organic solvent (like ethanol) in the use, and not only use cost is high and be easy to generate pollution.The floatating agent of sodium chloride N-alkyl morpholine that adopts in producing at present is the pale yellow oily liquid body, the method that field by using stoste directly drips, and owing to medicament difficulties in dispersion in the solution in bittern, service efficiency is poor; Its production technology is complicated in addition, and cost of material is high, and the medicament use cost is bigger.
Summary of the invention
The present invention will to separate technical problem be the deficiency to prior art, be to provide that a kind of novel flotation effect is good, the floatating agent of sodium chloride of good dispersion.
Another technical problem to be solved by this invention provides a kind of preparation method of above-mentioned floatating agent of sodium chloride.Its preparation method is simple, and is workable, and prepared floatating agent of sodium chloride can directly use aborning.
Technical problem to be solved by this invention is to realize through following technical scheme.The present invention is a kind of floatating agent of sodium chloride, is characterized in, it is to be processed by following materials of weight proportions:
Polyvinyl alcohol 1～20;
Water 80～99.
In the above-described floatating agent of sodium chloride technical scheme, the degree of polymerization of described polyvinyl alcohol is preferably 500～10000, further is preferably 1500～2500.
Above-described floatating agent of sodium chloride can prepare through following method: get granule of polyvinyl alcohol, add entry by described weight ratio; Stir, dissolve until particle fully heat temperature raising to 90～100 ℃ while stirring; Cooling; The water of the equivalent that adding loses because of heating evaporation stirs, and promptly gets.Can also be after stirring, soak at room temperature 5-24 hour, stir again, heat, dissolve.
Above-described floatating agent of sodium chloride can also prepare through following method: after taking by weighing raw material by described weight proportion, heat water to 45-55 ℃; Slowly add granule of polyvinyl alcohol then, the limit edged stirs, continuation rising temperature to 90～100 ℃; Dissolve fully until particle, cool off, add the water of the equivalent that loses because of heating evaporation; Stir, promptly get.
The present invention and be the liquid of thickness with the prepared floatating agent of sodium chloride of the inventive method, itself is the aqueous solution, good dispersion in bittern can directly use as collecting agent.Floatating agent of sodium chloride of the present invention is good to the sodium chloride flotation effect.And this flotation agent colorless and odorless, there is not corrosivity, safe and convenient to use, reagent cost is low.
