Abstract
The invention relates to a low-temperature eutectic liquid used in refrigerated and frozen product transportation and preservation, and a preparation method thereof. The liquid is mainly composed of the raw materials of, by weight, 0.06-0.15% of carbomer, 0.01-0.04% of sodium carboxymethyl cellulose, 0.03-0.06% of sodium hydroxide, and 99.75-99.9% of water. According to the invention, water and carbomer are added into a reaction vessel according to the ratio; the mixture is stirred until completely dissolved; sodium carboxymethyl cellulose is added while stirring, and a sodium hydroxide solution is finally added; and the mixture is well mixed. The liquid provided by the invention is a food-grade material, and has the advantages such as no toxic or side effect, environment-friendliness, no pollution, simple and convenient preparation, low cost, and suitability for industrialized productions.
Description
Technical field:
The present invention relates to a kind of cold storage agent, relate in particular to a kind of low temperature eutectic liquid and compound method thereof for refrigeration, frozen prods transportation preservation.
Background technology:
At present, of a great variety for the cold storage agent of refrigeration, frozen prods transportation preservation.As: Japanese Patent JP57023670 discloses a kind of cold storage agent, and its composition is the mixed aqueous solution of sodium-chlor and ammonium nitrate; Japanese Patent JP57174670 discloses a kind of cold storage agent, and main component is aqueous sodium formate solution, suitably adds sanitas; US Patent No. 4689164 discloses a kind of eutectic salts solution cold storage agent, is the mixed aqueous solution of sodium sulfate, Repone K, ammonium chloride; European patent EP 260759 disclosed cold storage agent are mixed aqueous solutions of Repone K and ammonium chloride; European patent EP 260772 is disclosed to be the eutectic thing of Repone K, water, ethanol.Although above cold storage agent belongs to the eutectic salt cold-storage agent together, cold storage capacity is less, and ctystallizing point is lower, and the condensate depression that the cold-storage phase transformation occurs is larger, and cost is higher, and cold discharges can not be lasting.
Summary of the invention:
In order to address the above problem, the invention provides a kind of cold storage capacity is large, the overcooling degree is little, cost is low low temperature eutectic liquid and compound method thereof.
Technical scheme of the present invention is: low temperature eutectic liquid, the raw material that mainly contains following weight percent forms carbomer 0.06%～0.15%, Xylo-Mucine 0.01%～0.04%, sodium hydroxide 0.03%～0.06%., water 99.75%～99.9%.
Preferably, the weight percent of raw material is carbomer 0.1%, Xylo-Mucine 0.02%, sodium hydroxide 0.05%, water 99.83%.
The preparation method of low temperature eutectic liquid, step is as follows: add in proportion entry and carbomer in reactor, be stirred to fully dissolving, add while stirring Xylo-Mucine, add at last sodium hydroxide solution, mix.
Preferably, add entry and Carmomer after, stir 15-30 minute to fully dissolving, form suspension.
More preferably, add in proportion completely reacted suspension and water, be heated to while stirring 50 degree, evenly mix 25-30 and divide.
Preferably, behind the adding Xylo-Mucine, evenly mix 25-30 and divide.
Low temperature eutectic liquid of the present invention has been compared following advantage with existing cold storage agent:
1) draw materials, prepare simply, cost is low, environmental protection, pollution-free.
2) need freezing temperature to put 5 ℃ ± 1 ℃ of relative eutectic temperature point, the Refrigerating Machinery coefficient of performance (COP) height, the Conversion of energy utilization ratio is high, and is more energy-conservation more than 30% than traditional cool storage medium.
3) cold storage capacity is large, is 275.75KJ/KG, and published cold storage agent cold storage capacity all is lower than and is 250.00KJ/KG.Repeatedly solidify dissolving, can not occur being separated and the dynamic performance of ice storage reduction.
4) at 2 ℃ to 8 ℃ temperature range specific heats be: 23.70KJ/KGK, apparently higher than other cold storage agent, so the unit weight cold storage agent temperature period is long.Pack respectively with one kilogram of this cool storage medium and water and to place refrigerator-freezer to freeze, after the taking-up, place the environment of envrionment temperature 30 degree, eutectic liquid of the present invention melted complete in 10 hours, and water is only complete through thawing in 5.5 hours.
5) this cold storage agent freezing expansion rate is 5.5%, and the water rate of expansion is 9%, and other cold storage agent rate of expansion do not wait between 6.5---8.1.Therefore, eutectic liquid can of the present invention is measured larger in the large small vessels of relative volume.Manufacturing has the cold-storage accessory of cool storage function, and is low to the carrying capacity requirement of packaging vessel, not harsh to packing instructions.
6) little to corrosion of metal, copper sheet, lead flake, aluminium flake are placed eutectic liquid of the present invention, place half a year under the normal temperature after, it is former glossy that these metals still keep, therefore, eutectic liquid of the present invention adopts packaging container of metal to make various temperature control devices, long service life.
