Abstract
The invention relates to a novel biological ice bag and a preparation method thereof. The biological ice bag is prepared by mixing inorganic salts, sodium polyacrylate, Spain agarose and water with the mass ratio of (30-40):(1-1.8):(8-10):100. With use of a principle that a variety of inorganic salts are compounded and then dissolved in water and thus absorption efficiency is enhanced, a plurality of kinds of specific inorganic salts are screened for compatibility, Spanish agarose and sodium polyacrylate are added in the compounded inorganic salt, and the obtained gel effect is quite good, so that the whole ice bag is in a flocculent solid state at room temperature, has the advantages of good softness and better mechanical strength, is suitable for keeping samples with all kinds of shapes cold, and can be repeatedly used for more than 10 times in a long term; moreover, the phase transition temperature (freezing point) of the biological ice bag is -18 DEG C, and the freezing temperature is -20 DEG C; at indoor with room temperature of 20 DEG C, the cold storage time is as long as 5.5-6.2 hours, and the cold storage capacity of the ice bag is much higher than that of other ice bags.
Description
Technical field
The present invention relates to a kind of new bio ice bag and preparation method thereof, belong to ice bag preparing technical field.
Background technology
In scientific experimentation process, usually need to reach the object of preserving sample by cooling, transport and the preservation of experiment material also require to carry out when low temperature.And reach by use ice bag the way that cooling object is most economical practicality.
At present, on market, the type of ice bag is a lot, is divided into efficient cold-storage ice bag, Ice bag for preservation, biological medicine ice bag, water filling ice bag etc. according to purposes.But the cold-storage ability of current commercially available ice bag is poor, exist and melt comparatively fast, the defects such as cool-storage time is shorter, are difficult to reach desirable refrigeration.
Summary of the invention
The object of this invention is to provide a kind of new bio ice bag and preparation method thereof.The described biological ice bag more conventional ice bag cold insulation time is longer, and have physical strength high, soft, can recycle, make the features such as simple.
To achieve these goals, the present invention adopts following technical scheme:
A kind of new bio ice bag, is prepared with mass ratio 30-40:1-1.8:8-10:100 by two kinds of inorganic salt, sodium polyacrylate, Spain's agarose and water and obtains.
We find in test, and after two kinds of inorganic salt are water-soluble with rational proportion collocation, heat absorption capacity is stronger, and large owing to mixing rear density, and salt concn is high, and endothermic effect is more remarkable.Preferred inorganic salt, sodium polyacrylate, Spain's agarose, water mix with mass ratio 30-40:1.2:8:100.
In biological ice bag of the present invention, described inorganic salt are selected from the one in following combination: NaCL and Na
2sO
4combination, NaCL and KCL combination, NaCL and NH
4c combination or NaCL and Na
2cO
3combination; Consider the factor such as caloric receptivity, price after the molten water of composite inorganic salt, the preferred Na of the present invention
2sO
4be that 1:1-2 is composite with NaCL with mass ratio, preferred 1:2.
As the preferred embodiment of the present invention, described biological ice bag is obtained by the component of following mass parts: Na
2sO
410-20 part, NaCL20 part, sodium polyacrylate 1.2-1.8 part, Spain agarose 8-10 part, water 100g.
The present invention also provides the preparation method of above-mentioned biological ice bag, comprises the steps:
1) add water in inorganic salt, rapid stirring, obtains system 1;
2) in system 1, slowly add sodium polyacrylate equably, be stirred to granules swell and suspend, static treating is dissolved completely, obtains system 2;
3) in system 2, add Spain's agarose, stir, be heated to agarose and dissolve completely, obtain the liquid of transparent clear, be system 3;
4) pour in mould after system 3 being cooled to 40-50 DEG C, naturally cooling, obtain biological ice bag.
The present invention is the principle utilizing the composite rear water-soluble heat absorption efficiency of plurality of inorganic salt to strengthen, by filtering out several specific inorganic salt compatibility, and add Spain's agarose and sodium polyacrylate in composite inorganic salt after, gained gel effect is fine, make whole ice bag at normal temperatures in cotton-shaped solid-state, flexibility is good, and physical strength is better, be applicable to the sample cold insulation of all kinds of shape, can prolonged and repeated use more than 10 times; And biological ice bag transformation temperature (freezing point) of the present invention is-18 DEG C, freezing temperature is-20 DEG C; In normal temperature 20 DEG C of indoor, its cold-storage duration reaches 5.5-6.2 hour, and cold-storage ability is higher than other existing ice bag.
