Abstract
The invention discloses a kind of agent for storage of coldness, it is made up of the mixing of agar-agar, sodium carboxymethylcellulose, poly glycol monomethyl ether methyl methacrylate, NaOH, sodium tetraborate decahydrate and water.The formula of agent for storage of coldness of the present invention rationally, cold-storage and good environmental protection, and phase transition temperature is low, latent heat of phase change is big, is very suitable for being applied in low temperature field.
Description
Technical field
The present invention relates to a kind of agent for storage of coldness.
Background technology
At present, use inorganic phase-changing material refrigerator/freezer agent for storage of coldness more, although inorganic agent for storage of coldness latent heat of phase change is big,
But have the shortcomings that to be subcooled in use and be separated, influence cold-storage ability.In addition, most inorganic salts have corrosion
Property, be not suitable for refrigerator household appliances.And presented in liquid form more than inorganic agent for storage of coldness, there is the wind of leakage during use
Danger.
The content of the invention
The present invention is to overcome the weak point existing for above-mentioned prior art, there is provided a kind of agent for storage of coldness, it is intended to solve inorganic
The problem of cold-storage ability, corrosion and leakage existing for class agent for storage of coldness.
The present invention solves technical problem, adopts the following technical scheme that：
The invention discloses a kind of agent for storage of coldness, it is made up of each raw material mixing of following percentage by weight：
Preferably, it is made up of each raw material mixing of following percentage by weight：
It is another preferred, it is made up of each raw material mixing of following percentage by weight：
Agent for storage of coldness of the invention is by agar-agar, sodium carboxymethylcellulose, poly glycol monomethyl ether methyl methacrylate, hydrogen-oxygen
Change sodium, five kinds of mixing compositions of sodium tetraborate decahydrate and water.Wherein：Agar-agar plays increase agent for storage of coldness viscosity, improves cold-storage as gelling agent
The effect of agent stability；Sodium carboxymethylcellulose is tasteless, nontoxic white powder, and is soluble in cold water, forms gel, is reached
Weaken the purpose of agent for storage of coldness mobility；Poly glycol monomethyl ether methyl methacrylate improves organic and nothing as emulsifying agent
The compatibility of machine material, it is to avoid the generation of phenomenon of phase separation；The effect of NaOH and sodium tetraborate decahydrate is to reduce agent for storage of coldness
Phase transition temperature, while latent heat of phase change is maintained into level higher；The potential heat value of water is maximum in nature simple substance, therefore
Mixture is added it in lift agent for storage of coldness potential heat value.
Compared with the prior art, beneficial effects of the present invention are embodied in：
1st, cold-storage agent prescription of the invention rationally, cold-storage and good environmental protection, and phase transition temperature is low, latent heat of phase change is big, ten
Divide and be adapted to be applied in low temperature field；
2nd, agent for storage of coldness of the invention uses organic material, it is to avoid what existing inorganic agent for storage of coldness existed in use
Supercooling and the shortcoming being separated, while avoiding etching problem.
3rd, agent for storage of coldness of the invention is in gel, it is to avoid use disclosure risk present in process.
Brief description of the drawings
Fig. 1 is the DSC test curves of the gained agent for storage of coldness of the embodiment of the present invention 1；
Fig. 2 is the DSC test curves of the gained agent for storage of coldness of the embodiment of the present invention 2.
Specific embodiment
Embodiment 1
The agent for storage of coldness of the present embodiment, is made up of each raw material mixing of following percentage by weight：
Fig. 1 is the DSC test curves of the present embodiment gained agent for storage of coldness, as can be seen from the figure latent heat of phase change 208J/g, phase
- 13.8 DEG C of temperature.
Embodiment 2
The agent for storage of coldness of the present embodiment, is made up of each raw material mixing of following percentage by weight：
Fig. 2 is the DSC test curves of the present embodiment gained agent for storage of coldness, as can be seen from the figure latent heat of phase change 179J/g, phase
- 17.6 DEG C of temperature.
