Abstract
This invention discloses zinc nitrate hexahydrate chemical ice bag. The raw materials compromises, by mass, 12-18 parts of zinc nitrate hexahydrate, 2-5 parts of zinc acetate, 6-12 parts of oleyl alcohol polyoxyethylene ether, 10-15 parts of low-viscosity polyvinyl alcohol, and 30-35 parts of glycerine. The preparing method thereof comprises the following steps: (1) weighing each component, successively putting the zinc nitrate hexahydrate and zinc acetate into heated glycerine of 60-75 oC before stirring, keeping the temperature to be 60-75oC.. When the solution is transparent, stop heating, let the solution cool until the room temperature is reached; (2) successively adding oleyl alcohol polyoxyethylene ether and low-viscosity polyvinyl alcohol while stirring, and then stirring evenly. When the solution becomes uniform and transparent, stop stirring and seal the solution with nylon, by this way, the chemical ice bag is made.
Description
Technical field
The invention belongs to technical field of chemistry is and in particular to a kind of preparation method of zinc nitrate hexahydrate 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
Zinc nitrate hexahydrate ice bag cycle-index to increase, in ice bag, being separated, in order to reduce each composition in ice bag easily occurs in each composition
Between be separated, maintain stablize refrigeration for a long time.Therefore, develop a kind of new zinc nitrate hexahydrate chemical cold bag and there is weight
Big meaning.
Content of the invention
Present invention aims to the deficiencies in the prior art, provide a kind of zinc nitrate hexahydrate chemical cold bag and its preparation side
Method.
For achieving the above object, the technical scheme is that
A kind of zinc nitrate hexahydrate chemical cold bag, in terms of mass parts, including following raw material: zinc nitrate hexahydrate 12-18 part, zinc acetate 2-
5 parts, oleic alcohol polyoxyethylene ether 6-12 part, low-viscosity polyvinyl alcohol 10-15 part, glycerol 30-35 part.
A kind of preparation method of described zinc nitrate hexahydrate chemical cold bag, comprises the following steps:
(1) weigh by each ingredients weight parts, by the zinc nitrate hexahydrate weighing up, zinc acetate puts into successively and is heated to 60-75 DEG C sweet
In oil, stirring, keep 60-75 DEG C, after solution is transparent, stops heating, allow it naturally cool to room temperature；
(2) sequentially add oleic alcohol polyoxyethylene ether under stirring, low-viscosity polyvinyl alcohol stirs, when stirring simultaneously
Make it become to stop during transparence, after nylon encapsulation, obtain final product chemical cold bag.
Described oleic alcohol polyoxyethylene ether is ov series, and hydroxyl value is 75-90.
Beneficial effects of the present invention are as follows: adopt oleic alcohol polyoxyethylene ether, low-viscosity polyvinyl alcohol energy in the present invention
Enough effectively suppression are separated, and maintain good refrigeration, increase cooling time after repeatedly circulating.
Specific embodiment
Hereinafter embodiments of the present invention are illustrated by particular specific embodiment.
Embodiment 1
A kind of zinc nitrate hexahydrate chemical cold bag, in terms of mass parts, including following raw material: 16 parts of zinc nitrate hexahydrate, 3 parts of zinc acetate,
10 parts of oleic alcohol polyoxyethylene ether, 12 parts of low-viscosity polyvinyl alcohol, 30 parts of glycerol.
A kind of preparation method of described zinc nitrate hexahydrate chemical cold bag, comprises the following steps:
(1) weigh by each ingredients weight parts, by the zinc nitrate hexahydrate weighing up, zinc acetate puts into successively and is heated to 60-75 DEG C sweet
In oil, stirring, keep 60-75 DEG C, after solution is transparent, stops heating, allow it naturally cool to room temperature；
(2) sequentially add oleic alcohol polyoxyethylene ether under stirring, low-viscosity polyvinyl alcohol stirs, when stirring simultaneously
Make it become to stop during transparence, after nylon encapsulation, obtain final product chemical cold bag.
Described oleic alcohol polyoxyethylene ether is ov series, and hydroxyl value is 75-90.
Low-viscosity polyvinyl alcohol is according to polyvinyl alcohol product standard (usp25).
Refrigerator freezing below -20 DEG C of ice bag in the present embodiment, after 8 hours, melted through 26 hours under room temperature completely；Repeatedly
After freeze cycle 5000 times, cold storage capacity declines 1.7%.
Comparative example 1
Oleic alcohol polyoxyethylene ether 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 15 hours under room temperature；Repeatedly after freeze cycle 5000 times,
Cold storage capacity declines 23.2%.
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 both fall within scope of the claimed invention it is not limited to specific embodiment
Scope.
