Description
Technical field
The present invention relates to the technical field of cold-storage, specifically a kind of high efficient cryogenic phase change cold accumulating agent.
Background technology
Since twentieth century occurs in that world oil crisis, the energy and power saving are subject to the common concern of people, state
The inside and outside application study for phase-changing energy storage material is concentrated mainly on central air conditioning, heating, passive type solar energy and used heat
Fei Leng such as utilizes at the field.Agent for storage of coldness from phase-change accumulation energy, draw by this concept, for the research of phase-change material for cold storage
Using relatively fewer, the application in the cold chain transportation fields such as air conditioner refrigerating and food and medicine vaccine is concentrated mainly on.
Domestic agent for storage of coldness generally existing phase transition temperature is higher, the low defect of potential heat value, and CN101921578 discloses a kind of cold-storage
Agent, is made up of macromolecule and water, and its phase transition temperature is 0 DEG C, it is impossible to reach low temperature；Patent No. CN90109434.X
Agent for storage of coldness consist of potassium chloride and water；Exist and be separated and cause the rate of disintegration higher；External low-temperature cold energy storage agent price is held high
It is expensive, it is impossible to promote.
The content of the invention
It is an object of the invention to provide a kind of raw material sources high efficient cryogenic phase change cold accumulating agent extensively, moderate.
The technical solution used in the present invention is, a kind of high efficient cryogenic phase change cold accumulating agent, by following raw material percentage by weight
Than composition：Sodium chloride 15-20%, acetate ethylene copolymer 2-8%, dodecyl sodium sulfate 1-5%, nanometer titanium dioxide
Titanium 1-2%, borax 2-4%, balance of deionized water.
It is an advantage of the invention that have that phase transition temperature is low, separate out without salt crystal, latent heat of phase change value is high, iterative cycles without
The advantages of potential heat value decays, raw material are easy to get, and cost is relatively low, easily produce, safety non-toxic, in food fresh keeping, biology
There is in vaccine cold chain transportation potential using value.
Specific embodiment
The present invention is further described with the following Examples.
A kind of embodiment 1, high efficient cryogenic phase change cold accumulating agent, is made up of following raw materials by weight：Sodium chloride
20%th, acetate ethylene copolymer 2%, dodecyl sodium sulfate 5%, nano titanium oxide 1%, borax 4%, balance of go
Ionized water.
A kind of embodiment 2, high efficient cryogenic phase change cold accumulating agent, is made up of following raw materials by weight：Sodium chloride
15%th, acetate ethylene copolymer 8%, dodecyl sodium sulfate 1%, nano titanium oxide 2%, borax 2%, balance of go
Ionized water.
A kind of embodiment 3, high efficient cryogenic phase change cold accumulating agent, is made up of following raw materials by weight：Sodium chloride
18%th, acetate ethylene copolymer 5%, dodecyl sodium sulfate 3%, nano titanium oxide 1%, borax 3%, balance of go
Ionized water.
The preparation method of the high efficient cryogenic phase change cold accumulating agent be take exactly in proportion sodium chloride, acetate ethylene copolymer,
Dodecyl sodium sulfate, nano titanium oxide, borax and water, in adding blender, are heated to 30-40 DEG C, stir
1-2 hours so as to be well mixed, cool down 20-25 DEG C, become gelatin, packed with polybag or plastic casing.
It should be understood that the embodiment is only illustrative of the invention and is not intended to limit the scope of the invention.Furthermore, it is to be understood that
After the content for having read instruction of the present invention, those skilled in the art can be made various changes or modifications to the present invention,
These equivalent form of values are equally fallen within the protection domain limited by the application appended claims.
