Problems solved by technology

[0003] The current cold storage agent mainly includes polyvinyl alcohol-borax high-efficiency cold storage agent and phase change cold storage agent. The polyvinyl alcohol-borax high-efficiency cold storage agent is a cross-linked reaction between polyvinyl alcohol and borax that is fully expanded in water to form a body structure, and then absorbs a large amount of water. However, both polyvinyl alcohol and borax are chemical raw materials, especially borax is banned as a food additive by many countries in the world, which will have a negative impact on the human body
The phase change cold storage agent is made of sodium chloride aqueous solution as the main material, ammonium chloride, sodium carboxymethyl cellulose, borax, etc. Leakage will contaminate food and medicine, and seriously cause acute poisoning of users and eaters. Therefore, it is very necessary to study a non-toxic and harmless cooling agent
