Technical field
The present invention relates to phase-change material technical field, is specifically related to a kind of cold storing and fresh-keeping composite phase-change cool storage material.
Background technology
It is to ensure fresh food for the quality of fresh food is increasingly paid attention to the improvement of people's living standards
The quality of the fresh product such as quality, especially vegetables, fruit, phase change cold accumulating agent is served in Refrigerated Transport delivery process can not
Or scarce effect, and greatly reduce the rotten risk of fresh food.
The research of phase change cold accumulating agent at present has focused largely on solid-liquid phase change aspect, there is water of many scholars using hydrated salt
Solution is used as inorganic-phase variable agent for storage of coldness, and its latent heat of phase change is big, but there is serious phase separation, higher degree of supercooling and prepare behaviour
The problems such as making numerous and diverse, as described in patent CN85108305, its cooling substance is mixed using both ice, salt or ice, calcium chloride
Close or ice, salt, calcium chloride three are mixed, although it has the advantages that low cost, processes simple, but its refrigeration is not
It is too preferable, and container containing is corrosive, which also limits its application；For another example phase disclosed in patent CN102942905A
Temperature is filled a prescription in -15 DEG C or so of cold-storage phase-change material, and the medicine for using has ammonium chloride, dipotassium hydrogen phosphate, hydroxy ethyl fiber
Plain sodium, nano titanium oxide, deionized water etc., species is various, and process for preparation is loaded down with trivial details；The unnecessary medicine of addition is stored for material
Cold energy does not have too many contribution, some to add the latent heat of phase change for reducing raw material on the contrary.And have most organic matter phase-change material
Without degree of supercooling and phenomenon of phase separation.Therefore, the organic phase-change cold-storage phase-change material for studying function admirable becomes current cold-storage phase transformation
The important direction in one, field.
The content of the invention
For above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of degree of supercooling is as low as possible, chemically
The composite phase-change cool storage material that matter is stable, potential heat value is big.
To achieve the above object of the invention, present invention employs technical scheme below：
A kind of cold storing and fresh-keeping composite phase-change cool storage material, by sorbierite, borax, three kinds of material mixings of water are formed, respectively into
Point weight percent content be：Sorbierite is 0.8% -7%, and borax is 0.01% -0.1%, and remaining is water.
Can also be, a kind of cold storing and fresh-keeping composite phase-change cool storage material that the mass percentage content of each composition is：Sorb
Alcohol 1% -4.5%, borax 0.01% -0.06%, remaining is water.
Preferably, a kind of cold storing and fresh-keeping composite phase-change cool storage material, described composite phase-change cool storage material is by following matter
The raw material of amount percentage is obtained：Sorbierite 1%, borax 0.05%, remaining is water.
A kind of described cold storing and fresh-keeping composite phase-change cool storage material, the phase transition temperature of the composite phase-change cool storage material
For -1.5 DEG C--0.1 DEG C, latent heat of phase change is 325J/g -376.1J/g.
A kind of described cold storing and fresh-keeping composite phase-change cool storage material, it is characterised in that：By the sorbierite, borax, water
Three pours in container and mixes, while after being stirred until homogeneous, standing 2-5 minutes obtain final product.
Beneficial effect
The phase-change material for cold storage of the present invention almost without degree of supercooling, stable chemical nature, and raw material sources extensively, cost compared with
Low, nontoxic, it is convenient to prepare, and has preferable application prospect in terms of Refrigerated Transport and cold chain.
The advantages of processing simple, refrigeration is preferable, without corrosivity.
The species that processes raw material is few, and process for preparation is not loaded down with trivial details；Function admirable.
