Abstract
The invention provides a cold-storage agent. The cold-storage agent comprises main ingredients of an antifreeze agent, a thickening agent and water, wherein the antifreeze agent is selected from at least one of ethylene glycol, propylene glycol, glycerol and the like; the thickening agent is selected from at least one of sodium polyacrylate, sodium alginate, carboxymethyl cellulose sodium, chitosan and the like. When the cold-storage agent is prepared, the thickening agent is added into water to form a hydrogel, and then the antifreeze agent is added and mixed uniformly, so as to obtain the cold-storage agent. An ice bag prepared with the cold-storage agent provided by the invention can be used repeatedly, has preferable flexibility, is convenient to use and has preferable temperature-reducing effect.
Description
Technical field
The present invention relates to a kind of Novel cold-storage agent and preparation method thereof.
Background technology
The at present domestic cold storage agent generally using mainly comprises disposable products and can be used repeatedly type product.Disposable products generally comprise two kinds of chemical substances, and a kind of is ammonium nitrate, and another kind is sal soda, use the broken packing that is contained with two kinds of chemical substances of time-division don't push, two kinds of chemical substances mix, and chemical reaction occurs, this chemical reaction is thermo-negative reaction, thereby reaches cooling-down effect.The ice bag that utilizes above-mentioned cold storage agent to prepare, main drawback is: packing cost is higher, and packing inside bag is once damage, loses the cooling effect of ice bag.The type ice bag of can be used repeatedly adopts water injection type mostly, at the in-built water of rubber bag, then carries out freezing formation ice bag, the shortcoming of this ice bag is: freezing rear one-tenth ice cube is harder, meets the crooked places such as wrist, and hard ice cube and people's contact level are little, docile property is poor, uses inconvenience, and cooling-down effect is poor.
Summary of the invention
The object of this invention is to provide a kind of Novel cold-storage agent and preparation method thereof.
Another object of the present invention is to provide a kind of reusable, soft type ice bag.
In order to realize the object of the invention, a kind of Novel cold-storage agent of the present invention, take antifreezing agent, thickening material and water as main component.Described antifreezing agent is selected from least one in ethylene glycol, propylene glycol, glycerol etc.; Described thickening material is selected from least one in sodium polyacrylate, sodium alginate, sodium cellulose glycolate, chitosan etc.The molecular weight of described thickening material is more than 1,000 ten thousand dalton, and viscosity is more than 1500Pa.s.
Novel cold-storage agent of the present invention, is grouped into by the one-tenth of following weight part: antifreezing agent 20-60, thickening material 1-6, water 30-80.
Preferably, Novel cold-storage agent of the present invention, is grouped into by the one-tenth of following weight part: antifreezing agent 30-50, thickening material 2-5, water 45-70.
More preferably, Novel cold-storage agent of the present invention, is grouped into by the one-tenth of following weight part: antifreezing agent 40, thickening material 4, water 56.
The present invention also provides the preparation method of described cold storage agent: thickening material is added to the water to (about 1h), forms hydrogel, then add antifreezing agent to mix, obtain.
The present invention further provides a kind of reusable ice bag, in described ice bag, packing has cold storage agent of the present invention.Wrapping material can be used common plastics bag.Ice bag of the present invention is placed in to-20 ℃ of freezers or refrigerator 12h can be used.By ice bag still icing, not hardening in freezing tens of hours.
Novel cold-storage agent provided by the invention be take antifreezing agent, thickening material and water as main raw material, and each raw material sources are extensive, cheap and easy to get, environmentally friendly, and the ice bag that utilizes cold storage agent of the present invention to prepare is reusable, and flexibility is good, easy to use, and cooling-down effect is good.
