Abstract
The invention relates to a refrigerating material with cold-storage and cooling function and preparation thereof. The formula and preparation are that in normal atmospheric container the dissolve and mixing ave taken as first, i.e. in the 2.6-3.8% of polyacrylamide, the 8.5-10% of glycerine water solution is added by stirring then 16.9-19.2% of KNO3 8.5-14% of Na2SO4.10H2O and 59.5-46% call by weight rate) or H2O are added and stirred to colloidal material and formed by refrigerating under temp. lower than zero degree C. Advantages: soft and plastic quality, whithout large amount of liquid evolved, capable of being repeatedly used and simple technology etc. It can be widely used in medical treatment, cooling in high-temp. operation and fresh-preservation for vegetable etc.
Description
The present invention relates to a kind of novel material of cooling and method for making with cold accumulation cooling-down effect.
The cooling effect of natural or artificial ice cube, obtain more and more many application in medical treatment and aspects such as daily life, as the low temperature that is used for reducing fever patient's body temperature and cerebral trauma, hematencephalon patient's provisional rescue, biotechnological formulation transports and hot environment under the short-term of cooling, vegetables of food-drink fresh-keeping etc.But natural ice cube in the use, and particularly special conditions such as medical treatment uses down, owing to be subjected to scleroid form restriction and defective such as be easy to dissolve, makes troubles to its preservation and use.
The objective of the invention is to make a kind of novel material of cooling-sludge ice with artificial synthetic way, it is compared with natural ice cube has widely purposes and has more advantage, can replace natural ice cube to play the cold accumulation cooling-down effect, can overcome the shortcoming that the quality of natural ice is hard and dissolve back flowing water again.
The making of this kind sludge ice is adopted with dissolving and is mixed into the master, forms the new material product of this kind in mixing process, can carry out in the normal pressure mixing vessel.
The prescription and the ratio thereof of sludge ice see Table 1, and the sludge ice ingredient reaches table by weight proportion.This table gives the embodiment of this case and shows by weight proportion, also is the optimal formula rate of the present invention.
Table 1 sludge ice ingredient reaches table by weight proportion
| The composition title | Shared weight percent (%) | Present embodiment weight percent (%) |
| Polyacrylamide | 2.6～3.8 | 2.9 |
| Glycerol | 8.5～10 | 8.6 |
| KNO 3 | 16.9～19.2 | 17 |
| NH 4NO 3 | 4～7.0 | 5.7 |
| Na 2SO 4.10H 20 | 8.5～14 | 11 |
| H 2O | 59.5～46 | 54.8 |
The method that adopts above-mentioned prescription to make sludge ice is in non-pressure vessel the polyacrylamide stirring to be added glycerin solution, and then adds KNO

2O, after stirring into jelly, in being lower than freeze forming packing use under the zero degree temperature, also can be divided in (as plastics bag) freeze forming again in the bag of desired shape in advance, become a kind of transparence Hookean body of doing, it can reach the temperature identical with refrigeration chamber in the regular hour, and the refrigerated temperature is lower, and the temperature that sludge ice institute cold-storage freezes is also just low.
Can understand the temperature variations of sludge ice under different envrionment temperatures intuitively by two width of cloth trial curve figure.
Fig. 1 is the temperature variation curve (supposition room temperature be 30 ℃) of soft water under room temperature state, and therefrom as can be seen, the sludge ice of freeze forming is lower than room temperature through about 9 little fashion, that is has the function of certain refrigeration, has cooling effect preferably within 3 hours.
Fig. 2 is the temperature variation curve of sludge ice under the vacuum flask state.From this curve as can be seen, in 15 hours, still keep below 0 ℃, that is this kind sludge ice has the effect of cooling in the long time.
This novel artificial sludge ice had both had the characteristics of natural ice cube, have quality softness, plasticity-again, dissolve the no big quantity of fluid in back separate out, easy to carry, can repeatedly use repeatedly, characteristics such as nontoxic pollution-free is harmless, manufacture craft is simple.It can be processed into Any shape, also unlikelyly when low temperature is frozen into hard lump, and is insoluble again during high temperature, is unlikely to take place the flowing water phenomenon, and the repeated use of can regenerating under low temperature environment, and cost is lower, thereby has great practical value.
This kind sludge ice is in places such as industrial and mining enterprises; can be used for the labour protection of operating worker under the hot conditions; in medical treatment, can be used for human body cooling, bring down a fever, the protection at body local position when hemostasis and chemotherapy, the conveying of articles for use such as blood plasma, vaccine or medicine, food fresh keeping etc.
Embodiments of the invention adopt with table one sludge ice ingredient and by weight proportion epiphase with prescription, and in the table present embodiment per-cent data and narrated compound method and prepared, the temperature of its refrigeration chamber is-19 ℃.
