Abstract
The invention discloses a kind of cold-storage materials, are made of the mixing of agar-agar, sodium carboxymethylcellulose, poly glycol monomethyl ether methyl methacrylate, sodium hydroxide, sodium tetraborate and water.The formula of cold-storage material of the present invention is reasonable, cold-storage and good environmental protection, and phase transition temperature is low, latent heat of phase change is big, is very suitable for applying in low temperature field.
Description
Technical field
The present invention relates to a kind of cold-storage materials.
Background technique
Currently, refrigerator/freezer mostly uses inorganic phase-changing material with cold-storage material, although inorganic cold-storage material latent heat of phase change is big,
But the shortcomings that having supercooling in use and mutually separating, influence cold-storage ability.In addition, most inorganic salts have corrosion
Property, be not suitable for refrigerator household appliances.And inorganic cold-storage material is mostly presented in liquid form, there is the wind of leakage in use process
Danger.
Summary of the invention
The present invention is to overcome above-mentioned existing deficiencies in the technology, provides a kind of cold-storage material, it is intended to solve inorganic
Cold-storage ability present in class cold-storage material is poor, corrosion and the problem of leakage.
The present invention solves technical problem, adopts the following technical scheme that
The invention discloses a kind of cold-storage materials, are made of each raw material mixing of following weight percent:
Preferably, it is made of each raw material mixing of following weight percent:
It is another preferred, it is made of each raw material mixing of following weight percent:
Cold-storage material of the invention is by agar-agar, sodium carboxymethylcellulose, poly glycol monomethyl ether methyl methacrylate, hydrogen-oxygen
Change five kinds of sodium, sodium tetraborate and water mixing compositions.Wherein: agar-agar plays as gelling agent and increases cold-storage material viscosity, improves cold-storage
The effect of agent stability；Sodium carboxymethylcellulose is tasteless, nontoxic white powder, and is soluble in cold water, forms gel, reaches
Weaken the purpose of cold-storage material mobility；Poly glycol monomethyl ether methyl methacrylate improves organic and nothing as emulsifier
The compatibility of machine material avoids the generation of phenomenon of phase separation；The effect of sodium hydroxide and sodium tetraborate is to reduce cold-storage material
Phase transition temperature, while latent heat of phase change is maintained into higher level；The potential heat value of water is the largest in nature simple substance, therefore
Mixture is added it in promote cold-storage material potential heat value.
Compared with the prior art, the beneficial effects of the present invention are embodied in:
1, cold-storage agent prescription of the invention is reasonable, cold-storage and good environmental protection, and phase transition temperature is low, latent heat of phase change is big, and ten
Divide and is suitble to apply in low temperature field；
2, cold-storage material of the invention uses organic material, and it is existing in use to avoid existing inorganic cold-storage material
The shortcomings that being subcooled and mutually separating, while avoiding etching problem.
3, cold-storage material of the invention is in gel, avoids disclosure risk present in use process.
Detailed description of the invention
Fig. 1 is the DSC test curve of 1 gained cold-storage material of the embodiment of the present invention；
Fig. 2 is the DSC test curve of 2 gained cold-storage material of the embodiment of the present invention.
Specific embodiment
Embodiment 1
The cold-storage material of the present embodiment is made of each raw material mixing of following weight percent:
Fig. 1 is the DSC test curve of cold-storage material obtained by the present embodiment, as can be seen from the figure latent heat of phase change 208J/g, phase
- 13.8 DEG C of temperature.
Embodiment 2
The cold-storage material of the present embodiment is made of each raw material mixing of following weight percent:
Fig. 2 is the DSC test curve of cold-storage material obtained by the present embodiment, as can be seen from the figure latent heat of phase change 179J/g, phase
- 17.6 DEG C of temperature.
