Description
Technical field
The present invention relates to a kind of cryochemistry ice bag and preparation method thereof, belong to technical field of chemistry.
Background technology
Chemical cold bag utilizes some chemical substance (as ammonium salt, nitrate) can absorb heat in course of dissolution, and the principle that the temperature in bag is declined rapidly and making.It is mainly used in health care (as cold compress detumescence), or food fresh keeping, or medicine (as vaccine) refrigeration etc., there is good effect.In a word, chemical cold bag plays an important role in daily life.
Usual people use ice cube to realize the object of cooling, but use ice cube to bring very big inconvenience, and if ice cube is solid, contact area is little, lowers the temperature uneven, is difficult to realize expected effect.Chemical cold bag is compared with ice cube, and chemical cold bag has the features such as volume is little, quality is light, chilling temperature is low, production cost is low, easy to use.Because it has these features, chemical cold bag more and more attracts the eyeball of people.
Document [Chen Ping Kun, novel quick cooling chemical ice-bag, invention and innovation, 2013.11] report a kind of can the chemical cold bag of fast cooling, its be by solid ammonium chloride powder and crystal barium hydroxide powder in mass ratio 2:5 there is the endothermic reaction and realize fast-refrigerating.Although this method energy fast-refrigerating, the heat due to the water-soluble absorption of ammonium chloride is not very large, and barium hydroxide water-soluble be release heat, cause the temperature of freezing low not, be difficult to the needs meeting practical application.Therefore, develop a kind of new chemical cold bag and very important effect is played to people.
Summary of the invention
For above-mentioned the deficiencies in the prior art, technical problem to be solved by this invention proposes a kind of cryochemistry ice bag extending cooling time and preparation method thereof.
The present invention for the taked technical scheme that solves the problem is:
A kind of cryochemistry ice bag, is made up of each component of following weight: barium hydroxide 80 ~ 90 parts, 50 ~ 60 parts, ammonium nitrate, poly amic acid 1 ~ 5 part, sodium phosphate trimer 10 ~ 20 parts, ethylene glycol 15 ~ 25 parts, triethanolamine 3 ~ 9 parts.
Its weight is as follows:
Barium hydroxide 85 parts, 55 parts, ammonium nitrate, poly amic acid 3 parts, sodium phosphate trimer 15 parts, ethylene glycol 20 parts, triethanolamine 6 parts.
In the present invention, described ammonium nitrate heat of solution is heat absorption, but its dissolving is larger than the heat of solution of ammonium chloride, reacts and can absorb more heats, make environment temperature generation rapid drawdown with barium hydroxide.Poly amic acid has strong cohesive and thickening property, energy accumulating in a certain region, can reduce energy loss, add cooling time.Sodium phosphate trimer has peptizaiton, slows down ammonium nitrate and barium hydroxide reaction speed, increases cooling time.Ethylene glycol is antifreezing agent, is changed the freezing point of chemical cold bag by the ethylene glycol adding different amount.Triethanolamine, heat release can regulate the temperature of chemical cold bag.
The preparation method of described cryochemistry ice bag, comprises the steps:
(1) weigh by each ingredients weight parts proportion speed, joined in barium hydroxide by the poly amic acid weighed up and stir, mixing speed is 100 ~ 120r/min, and be heated to 50 ~ 60 DEG C, when solution present transparent after, stop heating, allow it naturally cool to room temperature, obtain solution A;
(2) under stirring, add ammonium nitrate successively, sodium phosphate trimer, in solution A, make it stir, obtain solution B;
(3) in solution B, first adding after triethanolamine stirs, then add ethylene glycol, when stirring and make it become transparence, with bag encapsulation, cryochemistry ice bag can be obtained.
The invention has the beneficial effects as follows:
Chemical cold bag feature disclosed in this invention: ammonium nitrate heat of solution is heat absorption, but its dissolving is larger than the heat of solution of ammonium chloride, react with barium hydroxide and can absorb more heats, make environment temperature generation rapid drawdown, apply the peptizaiton of sodium phosphate trimer simultaneously, slow down ammonium nitrate and barium hydroxide reaction speed, increase cooling time.
