Abstract

The invention discloses a coolant. The coolant is formed by mixing agar-agar, sodium carboxymethylcellulose, methoxy polyethylene glycol methacrylate, sodium hydroxide, sodium tetraborate decahydrate and water. The coolant disclosed by the invention is reasonable in formula, good in cold accumulation and environmental protection performance, low in phase-transition temperature and high in latent heat of phase change, and is very suitable for being applied in low temperature fields.

Description

technical field [0001] The invention relates to a cold storage agent. Background technique [0002] At present, inorganic phase-change materials are mostly used in refrigerators / freezers for cold storage. Although inorganic cool-storage agents have a large phase-change latent heat, they have the disadvantages of overcooling and phase separation during use, which affects the cold storage capacity. In addition, most inorganic salts are corrosive and are not suitable for refrigerators and home appliances. In addition, inorganic cooling agents are mostly in liquid form, and there is a risk of leakage during use. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned prior art, the present invention provides a cold storage agent, aiming at solving the problems of poor cold storage capacity, corrosion and leakage of inorganic cold storage agents. [0004] The present invention solves technical problem, adopts following technical scheme...
