More welcome, therefore, Cool Storage Technology is more and more concerned, and Cool Storage Technology is to utilize the effective means such as various physics, chemistry, machinery
Cold is stored in agent for storage of coldness, it is necessary to when the process that again discharges the cold of storage.Produced by the technology
Cold can be efficiently stored, meets various physics again, this material of chemical requirements is referred to as agent for storage of coldness.
But current agent for storage of coldness using inorganic salts, alcohols and the silver iodide for core agent, copper sulfide, xanthans, α-
Azophenlyene, sodium pyrophosphate etc., freeze-off time is long, the cold insulation time is short, and performance is unstable, due to introducing substantial amounts of industrial chemicals, nothing
Method is accomplished nontoxic, if agent for storage of coldness is revealed in transportation, contaminated food products or medicine can cause serious consequence.
The content of the invention
Goal of the invention：The invention provides a kind of agent for storage of coldness, the agent for storage of coldness solve existing agent for storage of coldness freeze-off time it is long,
The problem of cold insulation time is short；Meanwhile solve the problems, such as that existing agent for storage of coldness toxicity is big, performance is unstable.
Technical scheme：The agent for storage of coldness of the present invention, by weight percentage, including：
In the preferred embodiment of the present invention, described agent for storage of coldness, by weight percentage, including：
In the preferred embodiment of the present invention, described agent for storage of coldness, by weight percentage, including：
In above-mentioned agent for storage of coldness, the high hydroscopic resin is starch-grafted acrylates and starch-grafted acrylamide
In one or more.
The acrylates is one or both of PAA and potassium acrylate.
In above-mentioned agent for storage of coldness, the nano controlled-release carrier is for polyalkylcyanoacrylate, polyester and derivative or altogether
Polymers.
