Abstract
The invention discloses a chemical ammonium alum ice bag. The chemical ammonium alum ice bag comprises, by weight, 15-25 parts of ammonium alum, 3-5 parts of sodium phosphate, 8-12 parts of medium-viscosity polyvinyl alcohol, 4-10 parts of C10-18 alkyl ester sodium sulfonate and 30-35 parts of butanol. A preparation method of the chemical ammonium alum ice bag includes the steps of 1, weighing the components according to the weight parts, sequentially placing the weighed ammonium alum and sodium phosphate into the butanol heated to 55-65 DEG C, stirring the solution, keeping the temperature at 55-65 DEG C, stopping heating after the solution becomes transparent and naturally cooling the solution to the indoor temperature; and 2, sequentially adding the medium-viscosity polyvinyl alcohol and the C10-18 alkyl ester sodium sulfonate into the solution in the stirring state, stirring the solution uniformly, stopping stirring when the solution is stirred uniformly and becomes transparent and carrying out nylon packaging to obtain the chemical ice bag.
Description
Technical field
The invention belongs to technical field of chemistry is and in particular to a kind of preparation method of ammonium alum chemical cold bag.
Background technology
In recent years, people are more and more wider to chemical cold bag range, and obtain certain achievement in research.In prior art, with
Ammonium alum ice bag cycle-index to increase, in ice bag, being separated, in order to reduce the phase between each composition in ice bag easily occurs in each composition
Separate, maintain and stablize refrigeration for a long time.Therefore, develop a kind of new ammonium alum chemical cold bag to be significant.
Content of the invention
Present invention aims to the deficiencies in the prior art, provide a kind of ammonium alum chemical cold bag and preparation method thereof.
For achieving the above object, the technical scheme is that
A kind of ammonium alum chemical cold bag, in terms of mass parts, including following raw material: ammonium alum 15-25 part, sodium phosphate 3-5 part, middle viscosity gathers
Vinyl alcohol 8-12 part, c10-18Hydrocarbyl carbonate sodium sulfonate 4-10 part, butanol 30-35 part.
A kind of preparation method of described ammonium alum chemical cold bag, comprises the following steps:
(1) weigh by each ingredients weight parts, by the ammonium alum weighing up, sodium phosphate puts in the butanol being heated to 55-65 DEG C successively, stirs
Mix, keep 55-65 DEG C, after solution is transparent, stops heating, allow it naturally cool to room temperature；
(2) viscosity polyvinyl alcohol, c in sequentially adding under stirring10-18Hydrocarbyl carbonate sodium sulfonate, stirs, and works as stirring
Uniformly and make it become to stop during transparence, after nylon encapsulation, obtain final product chemical cold bag.
Middle viscosity polyvinyl alcohol is according to polyvinyl alcohol product standard (usp25).
Beneficial effects of the present invention are as follows: viscosity polyvinyl alcohol in adopting in the present invention, c10-18Hydrocarbyl carbonate sodium sulfonate mixes
Can effectively suppress separated, sodium phosphate can prevent ice bag supercool, maintain good refrigeration after repeatedly circulating, greatly increase
Cooling time.
Specific embodiment
Hereinafter embodiments of the present invention are illustrated by particular specific embodiment.
Embodiment 1
A kind of ammonium alum chemical cold bag, in terms of mass parts, including following raw material: 16 parts of ammonium alum, 4 parts of sodium phosphate, middle viscosity polyethylene
10 parts of alcohol, c10-186 parts of hydrocarbyl carbonate sodium sulfonate, 30 parts of butanol.
A kind of preparation method of described ammonium alum chemical cold bag, comprises the following steps:
(1) weigh by each ingredients weight parts, by the ammonium alum weighing up, sodium phosphate puts in the butanol being heated to 55-65 DEG C successively, stirs
Mix, keep 55-65 DEG C, after solution is transparent, stops heating, allow it naturally cool to room temperature；
(2) viscosity polyvinyl alcohol, c in sequentially adding under stirring10-18Hydrocarbyl carbonate sodium sulfonate, stirs, and works as stirring
Uniformly and make it become to stop during transparence, after nylon encapsulation, obtain final product chemical cold bag.
Refrigerator freezing below -20 DEG C of ice bag in the present embodiment, after 8 hours, melted through 24 hours under room temperature completely；Repeatedly
After freeze cycle 5000 times, cold storage capacity declines 1.3%.
Comparative example 1
Middle viscosity polyvinyl alcohol is not contained, remaining is with embodiment 1. in this comparative example raw material
After ice bag in the present embodiment freezes 8 hours, melted completely through 11 hours under room temperature；Repeatedly after freeze cycle 5000 times,
Cold storage capacity declines 37.1%.
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 both fall within scope of the claimed invention it is not limited to specific embodiment
Scope.
