Description

A kind of transformation temperature is between 2 DEG C -8 DEG C cool storage material and preparation method thereof
Technical field
The present invention relates to a kind of cool storage material and preparation method thereof, and in particular to a kind of transformation temperature is between 2 DEG C -8 DEG C of storage Cold material and preparation method thereof, belongs to technical field of chemistry.
Background technology
The biological products such as vaccine, diagnostic reagent are the important leverage means for preventing disease from infecting, safeguarding human life and health. With the development of modern society, more and more biological products need refrigeration, heat insulation transportation.Large batch of product can be by cold Hide car fuel oil, energization and realize refrigerated transport.The product of small lot is then more universal by highway, railway, air transportation, and is based on Economic consideration, in a short time such transport can not be transported by refrigerator car and replaced completely.It is still to ensure by phase-change material for cold storage The important channel of quality of the small lot biological products in transportation.Therefore, in recent years, novel phase-change material for cold storage is developed Become one, field important research direction.
At present, market is still, with water as solvent, and to add other materials with wide phase-change material for cold storage, such as inorganic Salt (Huang Yan, chapter comes research Refrigeration Technique of the Cold Chain Logistics with compound cool storage material, 2016,36,33-35.).This kind of material The advantage of material is cheap, simple production process, thus is employed for the cold-storage heat-preserving of many kind biological products.Such coolness storing material Material is using preceding needing precooling to freeze (be normally placed at -18 DEG C freeze storehouses in), and the storage of vaccine kind biological product, cold chain transportation temperature Degree requirement is 2 DEG C -8 DEG C, therefore, by with the transport process of the phase-change material for cold storage of water as solvent, can frequently result in vaccine etc. There is the phenomenon of supercooling in biological products, thus cause these biological products activity, function reduction, even lose.When people use These lose activity or function biological products, it will there is unpredictable consequence, the lighter has adverse reaction, and severe one can disable Or it is lethal.Although once trial certain methods (term " balancing " such as in industry, i.e., after freezing in cold chain transportation industry Cool storage material is absorbed heat under normal temperature or refrigerated storage temperature, and temperature is reused after rising) such issues that solve, but effect pays no attention to always Think.
Therefore, exploitation phase-change material for cold storage of the transformation temperature between 2 DEG C -8 DEG C, urgent as technical field of biological material is essential Will.

Specific embodiment
Make specific introduction to the present invention below in conjunction with specific embodiment.
First, liquid A is prepared
With volume percentage, prepare each component for preparing liquid A, refer to table 1.
Table 1 is used to prepare each component and proportioning of liquid A
Preparation method:At room temperature, certain herbaceous plants with big flowers alkane, hendecane, dodecane, tridecane, the tetradecane, pentadecane and hexadecane are mixed Close, stir 10min, that is, obtain liquid A.
Certain herbaceous plants with big flowers alkane, hendecane, dodecane, tridecane, the tetradecane, pentadecane and hexadecane are homologue, and they have similar But incomplete same physics and chemical property.The liquid A being made up of these homologues, is to prepare in the cool storage material later stage During involved chemical reaction provide necessary reacting environment and material base.Meanwhile, themselves it is also coolness storing material The important component of material.
2nd, cool storage material is prepared
At room temperature, to the copper powder that 4- nitrophenols, trimethyl cetyl ammonium bromide and 800 mesh are added in above-mentioned liquid A, Stirring 1-2h, filtering removes filter residue, collects filtrate, obtains final product the cool storage material that transformation temperature is between 2-8 DEG C.Wherein, liquid A, 4- nitre The mass ratio of base phenol, trimethyl cetyl ammonium bromide and copper powder is 1000:10:1:1.
After the copper powder of 4- nitrophenols, trimethyl cetyl ammonium bromide and 800 mesh is added in liquid A, change Reaction is learned, fragrant amine substance is produced, they are the another important component of cool storage material, these fragrant amine substances and liquid A Middle kinds of ingredients synergy, can promote cool storage material integrally to give play to good cold-storage and act on.
As can be seen here, cool storage material of the invention has given full play to the association of kinds of ingredients by physics and the effect of chemistry Same-action, promotes material integrally to give play to good cold-storage and acts on.
3rd, transformation temperature is tested
After tested, the transformation temperature of each group cool storage material corresponding with table 1 is shown in Table 2.
The transformation temperature of each cool storage material under the different formulations of table 2
Group number 1 2 3 4 5 6 7
Transformation temperature 2.0℃ 3.0℃ 5.0℃ 7.0℃ 8.0℃ 4.0℃ 6.0℃
As can be seen here:
(1) cool storage material transformation temperature of the invention is between 2 DEG C -8 DEG C, and phase transition temperature is suitable, and evaporation latent heat is big, cold accumulation effects It is good, for needing to refrigerate, being incubated and temperature range includes 2 DEG C of products in -8 DEG C of intervals, will not using cool storage material of the invention There is the phenomenon of supercooling or overheat, i.e., be both not in 2 DEG C of the minimum temperature less than product requirement, be also not in higher than product It is required that 8 DEG C of maximum temperature, 2 DEG C of -8 DEG C of temperature controls are realized well;
(2) ratio by adjusting each component in preparation process of the invention, you can easily realize the regulation and control of phase transition temperature, fit Together in prepare with scale.
4th, application method
Vaccine cold chain temperature is 2 DEG C -8 DEG C, cold storage insulation box cold chain transportation dispatching vaccine, it is only necessary to by cold-storage of the invention Then material is placed directly in inside incubator, uses around vaccine in 2 DEG C or 3 DEG C freezings, over time, stores Cold material and vaccine temperature can be raised, and cool storage material and vaccine temperature can be higher than 8 DEG C, and vaccine has substantially from point of origin to receiving point Time, arrival receiving point time vaccines temperature can be made still to be below 8 DEG C by adjusting the usage amount of cool storage material.
In temperature than especially northern area of relatively low winter etc., in order that incubator intradermal vaccine product temperature is not less than 2 DEG C, Proper temperature (7 DEG C or 8 DEG C), appropriate cool storage material of the invention can be placed in incubator, vaccine periphery, to resist Low temperature.
As can be seen here, cool storage material of the invention, using preceding less than cool storage material transformation temperature, higher than desired lowest temperature The lower freezing of degree can be used after freezing, it is not necessary to " balancing " so-called in industry, simplify operation difficulty, greatly improve Operating efficiency.
It should be noted that above-described embodiment the invention is not limited in any way, all use equivalents or equivalent change The technical scheme that the mode changed is obtained, all falls within protection scope of the present invention.
