Description
Technical field
The present invention relates to a kind of sodium salt chemical cold 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.
At present, people are to the chemical cold bag of chemical cold bag research to be often ammonium nitrate be major ingredient.This can absorb amount of heat because ammonium nitrate is water-soluble, is the good material of fast-refrigerating." quick cooling chemical ice-bag " (publication number: CN1087417A, publication date: on June 1st, 1994) is called as Chinese patent literature discloses a kind of name.It discloses a kind of quick cooling chemical ice-bag, its refrigerant is made up of ammonium nitrate, sal soda, and ice bag temperature can be down to zero following.Visible, ammonium nitrate is one of preferred material of chemical cold bag.
In fact, except ammonium nitrate, SODIUMNITRATE is water-soluble is also heat absorption.Document [Cui Zhongmin, the development of chemical cold bag, Shanghai chemical industry, the 6th phase] reports SODIUMNITRATE when mixing in the ratio of 75:100 with water, and the temperature of solution can be made to change to-5.3 DEG C from 13.2 DEG C, and temperature variation can reach 18 DEG C.Visible, SODIUMNITRATE also can reduce temperature effectively.Although SODIUMNITRATE also can be freezed, at present special for SODIUMNITRATE as refrigeration agent chemical cold bag research remain very limited.Therefore, develop a kind of new chemical cold bag and very important effect is played to people's health care.
Summary of the invention
For above-mentioned the deficiencies in the prior art, technical problem to be solved by this invention is that proposing a kind of take SODIUMNITRATE as sodium salt chemical cold bag of refrigeration agent and preparation method thereof.
The present invention for the taked technical scheme that solves the problem is:
A kind of sodium salt chemical cold bag, is made up of each component of following weight: SODIUMNITRATE 40 ~ 50 parts, Sodium Tetraborate 10 ~ 20 parts, sal glauberi 20 ~ 30 parts, Xylo-Mucine 1 ~ 3 part, water glass 1 ~ 3 part, 1 ~ 5 part, sodium-chlor, 1 ~ 5 part, sodium hydroxide.
Its weight is as follows:
SODIUMNITRATE 45 parts, Sodium Tetraborate 15 parts, sal glauberi 25 parts, Xylo-Mucine 2 parts, water glass 2 parts, 3 parts, sodium-chlor, 3 parts, sodium hydroxide.
In the present invention, described SODIUMNITRATE solution heat is heat absorption, water-solublely can absorb heat, makes surrounding temperature generation rapid drawdown.Sal glauberi dehydration is also endothermic process, and dehydration is relatively slower, increases cooling time.Sodium Tetraborate loses eight molecular crystal water 60 DEG C time, and dissolving for SODIUMNITRATE provides water, increases cooling time.Xylo-Mucine has slow setting, the effect of thickening and maintenance moisture.Water glass has strong cohesive force and high intensity, 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 sodium salt chemical cold bag, comprises the steps:
(1) weigh by each ingredients weight parts proportion speed, joined in Sodium Tetraborate by the Xylo-Mucine weighed up and stir, stirring velocity is 100 ~ 150r/min, and be heated to 60 ~ 70 DEG C, when solution present transparent after, stop heating, allow it naturally cool to room temperature, obtain solution A;
(2) under whipped state, add SODIUMNITRATE successively, sal glauberi, water glass, in solution A, makes it stir, obtains 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, sodium salt chemical cold bag can be obtained.
The invention has the beneficial effects as follows:
Chemical cold bag feature disclosed in this invention: SODIUMNITRATE is dissolved and sal glauberi dehydration is all thermo-negative reaction, the temperature of surrounding is even lower, applies strong cohesive force and the high strength of water glass, energy accumulating in a certain region simultaneously, reduce power loss, add cooling time.
