Abstract
The invention discloses a sodium sulfate decahydrate chemical ice bag. The sodium sulfate decahydrate chemical ice bag comprises the following raw materials in parts by mass: 18-25 parts of sodium sulfate decahydrate, 3-5 parts of calcium sulfate, 6-10 parts of polyacrylamide, 8-12 parts of middle-viscosity polyvinyl alcohol and 50-65 parts of butanol. A preparation method of the sodium sulfate decahydrate chemical ice bag comprises the following steps that (1) all the components are weighed according to the parts by weight, the weighed sodium sulfate decahydrate and the weighed calcium sulfate are sequentially put into the butanol heated to 60 DEGC-65 DEG C, stirring is conducted, the temperature of 60 DEGC-65 DEG is kept, after the solution is transparent, heating is stopped, and the solution is naturally cooled to the room temperature; and (2) the polyacrylamide and the middle-viscosity polyvinyl alcohol are sequentially added into the solution in a stirring state and are uniformly stirred, stirring is stopped when the solution is stirred to be uniform and is transparent, and the chemical ice bag is obtained after nylon packaging.
Description
Technical field
The invention belongs to technical field of chemistry, and in particular to a kind of preparation method of sal glauberi chemical cold bag.
Background technology
In recent years, people are more and more wider to chemical cold bag use range, and obtain certain achievement in research.Prior art
In, as sal glauberi ice bag cycle-index increases, in ice bag, being separated easily occurs in each composition, each in ice bag in order to reduce
Phase separation between composition, maintains to stablize refrigeration for a long time.Therefore, develop a kind of new sal glauberi chemical cold bag tool
It is of great importance.
The content of the invention
Present invention aims to the deficiencies in the prior art, there is provided a kind of sal glauberi chemical cold bag and its preparation
Method.
For achieving the above object, the technical scheme is that：
A kind of sal glauberi chemical cold bag, in terms of mass parts, including following raw material：Sal glauberi 18-25 parts, calcium sulfate 3-
5 parts, polyacrylamide 6-10 parts, middle viscosity polyvinyl alcohol 8-12 parts, butanol 50-65 parts.
A kind of preparation method of described sal glauberi chemical cold bag, comprises the following steps：
（1）Weigh by each component weight portion, by the sal glauberi for weighing up, calcium sulfate puts into the fourth for being heated to 60-65 DEG C successively
In alcohol, stirring is kept for 60-65 DEG C, after solution is transparent, is stopped heating, is allowed which to naturally cool to room temperature；
（2）Polyacrylamide is sequentially added under stirring, middle viscosity polyvinyl alcohol stirs, when stirring and make
Which stops into during transparence, obtains final product chemical cold bag after nylon encapsulation.
Described Molecular Weight for Polyacrylamide is 400-500 ten thousand.
Middle viscosity polyvinyl alcohol is according to polyvinyl alcohol product standard（USP25）.
Beneficial effects of the present invention are as follows：Molecular weight is adopted in the present invention for the polyacrylamide of 400-500 ten thousand, middle viscosity
Polyvinyl alcohol effectively can suppress to be separated, and maintain good refrigeration, greatly increase cooling time after repeatedly circulating.
Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below.
Embodiment 1
A kind of sal glauberi chemical cold bag, in terms of mass parts, including following raw material：22 parts of sal glauberi, 3 parts of calcium sulfate,
8 parts of polyacrylamide, 10 parts of middle viscosity polyvinyl alcohol, 60 parts of butanol.
A kind of preparation method of described sal glauberi chemical cold bag, comprises the following steps：
（1）Weigh by each component weight portion, by the sal glauberi for weighing up, calcium sulfate puts into the fourth for being heated to 60-65 DEG C successively
In alcohol, stirring is kept for 60-65 DEG C, after solution is transparent, is stopped heating, is allowed which to naturally cool to room temperature；
（2）Polyacrylamide is sequentially added under stirring, middle viscosity polyvinyl alcohol stirs, when stirring and make
Which stops into during transparence, obtains final product chemical cold bag after nylon encapsulation.
Described Molecular Weight for Polyacrylamide is 400-500 ten thousand.
After 8 hours, under room temperature, Jing melts refrigerator freezing below -20 DEG C of ice bag in the present embodiment for 27 hours completely；Repeatedly
After freeze cycle 5000 times, cold storage capacity declines 1.8%.
Comparative example 1
Middle viscosity polyvinyl alcohol is not contained in this comparative example raw material, remaining is with embodiment 1.
After ice bag in the present embodiment is freezed 8 hours, under room temperature, Jing melts for 15 hours completely；Repeatedly after freeze cycle 5000 times,
Cold storage capacity declines 29.2%.
Without departing from the spirit and scope of the present invention, those skilled in the art should know that the present invention also has various changes
Change and improve, these changes and improvements are both fallen within scope of the claimed invention, it is not limited to specific embodiment
Scope.
