Abstract
The invention discloses a low-temperature ice bag with the temperature ranging from -2 DEG C to -8 DEG C. The ice bag consists of, by weight, polyvinyl alcohol 2-3 parts, CMC cellulose or slow-release agent 1-2 parts, ethylene glycol 15 parts, pure water 80 parts and triethanolamine 0.25-0.5 part. The low-temperature ice bag can play a cold accumulation role on low-temperature vaccine with the temperature ranging from -2 DEG C to -8 DEG C in the cold chain transportation process, the problem of refrigerated transportation of the low-temperature vaccine is solved, two thirds of the transportation cost can be saved by using the ice bag and cold chain package, a freezing point of the ice bag is -5.8 DEG C, and a storage solution can be provided for the vaccine with the temperature ranging from -2 DEG C to -8 DEG C.
Description
Technical field
The present invention relates to a kind of ice bag, be specifically related to one-2 ℃ to-8 ℃ of low temperature ice bags.
Background technology
Ice bag is in the market all take zero degree as freezing point or subzero is the ice bag of ice bag point, due to the uncontrollable ice bag temperature of common ice bag, therefore in a lot of occasions, can not use, in vaccine transportation, very strict to the requirement of temperature, need the strict temperature of controlling, at this moment common ice bag is just helpless.
Summary of the invention
The object of the present invention is to provide one temperature can be controlled to-2 ℃ to-8 ℃ of low temperature ice bags.
The present invention is achieved in that
A kind of-2 ℃ to-8 ℃ of low temperature ice bags, in ice bag, composition is comprised of the component of following weight portion: polyvinyl alcohol 2-3 weight portion, CMC cellulose or sustained release agent 1-2 weight portion, ethylene glycol 15 weight portions, pure water 80 weight portions, triethanolamine 0.25-0.5 weight portion.
The present invention also provides described-2 ℃ of preparation methods to-8 ℃ of low temperature ice bags, be specially: first by polyvinyl alcohol and pure water Hybrid Heating, after making it cooling, again with CMC cellulose, triethanolamine mix and blend, until product, become after paste, finally add ethylene glycol, stir and prepare composition in ice bag, then adopt conventional method to prepare ice bag.
The present invention can solve low temperature vaccine cold-storage effect in cold chain transportation process of-2 ℃ to-8 ℃, overcome the low temperature vaccine of refrigeration transportation, pack the cost of transportation that can save 2/3rds with this ice bag and cold chain, its freezing point is-5.8 ℃, can at the vaccine of-2 ℃ to-8 ℃, provide storage solution for temperature requirement.
Invention effect: the development of holding biologics, its biological reagent, low temperature medicine, vaccine etc. are also more and more, classification and temperature requirement be respectively difference and segmentation to some extent also, for the product that uses-2 ℃ to-8 ℃ preservations and freight charges can have personalized quality guarantee, at-2 ℃ of this invention to-8 ℃ of low temperature ice bags, for its solution need to be at the storage of the biological reagent of this temperature province cold insulation, low temperature medicine, vaccine and food and transportation cold chain.
The specific embodiment
A kind of-2 ℃ to-8 ℃ of low temperature ice bags, in ice bag, composition is comprised of the component of following weight portion: polyvinyl alcohol 2-3 weight portion, CMC cellulose or sustained release agent 1-2 weight portion, pure water 80 weight portions, triethanolamine 0.25-0.5 weight portion, ethylene glycol 15 weight portions, and ethylene glycol is the main component of anti-icing fluid, a kind of colourless, transparent, slightly sweet taste and there is hygroscopic thick liquid, it can be with any ratio and water when molten, when the concentration of its ethylene glycol is different, freezing point is also different, when ethylene glycol 15 weight portion, its freezing point is-5.8 ℃, when this ice bag is placed on to cryogenic freezing accumulation of energy, it just starts to freeze at-5.8 ℃, can be very stable by ice source perseverance degree between-2 ℃ to-8 ℃, vaccine to temperature requirement at-2 ℃ to-8 ℃, food has played insulation effect.
Claims (2)
1. one kind-2 ℃ to-8 ℃ of low temperature ice bags, it is characterized in that in described-2 ℃ to-8 ℃ low temperature ice bags, composition is comprised of the component of following weight portion: polyvinyl alcohol 2-3 weight portion, CMC cellulose or sustained release agent 1-2 weight portion, ethylene glycol 15 weight portions, pure water 80 weight portions, triethanolamine 0.25-0.5 weight portion.
2.-2 ℃ of preparation methods to-8 ℃ of low temperature ice bags described in claim 1, it is characterized in that: first by polyvinyl alcohol and pure water Hybrid Heating, after making it cooling, again with CMC cellulose, triethanolamine mix and blend, until product, become after paste, finally add ethylene glycol, stir and prepare composition in ice bag, then adopt conventional method to prepare ice bag.
