Description
Technical field
The present invention relates to a kind of new chemical 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 dissolution process, 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, cooling 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.
Ammonium nitrate (NH
4nO
3) be the clear crystals of no color or smell or the crystallization in white, soluble in water, and can a large amount of heat energy be absorbed and reduce temperature time water-soluble.Therefore, ammonium nitrate is one of preferred material of chemical cold bag.As Chinese patent literature discloses the chemical cold bag that a kind of name is called " chemical cold bag " (publication No.: CN 101929775A, date of publication: on December 29th, 2010).It is the chemical cold bag be made up of ammonium nitrate, sal soda, water, and it realizes formula rationally, and result of use is good, and production cost is low is target.And for example document [portable type chemical ice bag manufacture method, new technology in rural areas, the 10th phase in 2000] reports chemical cold bag and is made up of sal glauberi, monoammonium sulfate, sodium pyrosulfate, ammonium nitrate.When chemical cold bag coordinates by sal glauberi 42%, monoammonium sulfate 18%, sodium pyrosulfate 18%, ammonium nitrate 18%, the minimum temperature of chemical cold bag can reach-9 DEG C, and after continuing 3.5h, temperature becomes+13 DEG C; When chemical cold bag coordinates by sal glauberi 44%, monoammonium sulfate 16%, sodium pyrosulfate 20%, ammonium nitrate 20%, the minimum temperature of chemical cold bag can reach-9 DEG C, and after continuing 3.5h, temperature becomes+9 DEG C.Visible, although this chemical cold bag can freeze, temperature variation is fast, and cooling time is not long.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 new chemical 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 new chemical ice bag, be made up of each component of following weight: sal glauberi 50 ~ 60 parts, monoammonium sulfate 10 ~ 20 parts, sodium pyrosulfate 10 ~ 20 parts, 15 ~ 20 parts, ammonium nitrate, Xylo-Mucine 2 ~ 8 parts, polyvinyl alcohol 1 ~ 3 part, 3 ~ 7 parts, sodium-chlor, 1 ~ 3 part, sodium hydroxide.
Its weight is as follows:
Sal glauberi 55 parts, monoammonium sulfate 15 parts, sodium pyrosulfate 15 parts, 18 parts, ammonium nitrate, Xylo-Mucine 5 parts, polyvinyl alcohol 2 parts, 5 parts, sodium-chlor, 2 parts, sodium hydroxide.
In the present invention, described ammonium nitrate, monoammonium sulfate solution heat are heat absorptions, water-solublely can absorb heat, make surrounding temperature generation rapid drawdown.Sal glauberi dehydration is also endothermic process, and dehydration is relatively slower, increases the time of refrigeration.Xylo-Mucine has slow setting, the effect of thickening and maintenance moisture.Polyvinyl alcohol has good cohesiveness, energy accumulating in a certain region, can reduce power loss, add cooling time.Sodium-chlor is frostproofer, is changed the freezing point of chemical cold bag by the sodium-chlor adding different amount.Sodium hydroxide, heat release can regulate the temperature of chemical cold bag.
The preparation method of described new chemical ice bag, comprises the steps:
(1) weigh by each ingredients weight parts proportion speed, the Xylo-Mucine weighed up, polyvinyl alcohol are joined in half sal glauberi and stir, stirring velocity is 120 ~ 160r/min, and be heated to 65 ~ 75 DEG C, when solution present transparent after, stop heating, allow it naturally cool to room temperature, obtain solution A;
(2) under whipped state, add second half sal glauberi, monoammonium sulfate, sodium pyrosulfate, ammonium nitrate successively in solution A, make it stir, obtain solution B;
(3) in solution B, first adding after sodium hydroxide stirs, then add sodium-chlor, when stirring and make it become transparence, with bag encapsulation, new chemical ice bag can be obtained.
The invention has the beneficial effects as follows:
Chemical cold bag feature disclosed in this invention: ammonium nitrate, monoammonium sulfate dissolve and sal glauberi dehydration is all thermo-negative reaction, the temperature of surrounding is even lower, applies the strong cohesive property of polyvinyl alcohol simultaneously, energy accumulating in a certain region, reduce power loss, add the time of refrigeration.
