Problems solved by technology

There are supercooling and phase separation phenomena during the phase transition of inorganic cooling agents. At the same time, inorganic cooling agents are mostly corrosive and have high requirements for packaging containers; organic cooling agents are mainly solutions of paraffin, alcohol, acid, and higher alkanes. The agent can guarantee a better phase transition temperature, but it is easy to leak, volatile, flammable, even explode or be slowly oxidized by oxygen in the air and age, which affects the cold storage performance. At the same time, this kind of cold storage agent is dangerous and not suitable for air transportation; polymer The cold storage agent is to compound the polymer material with water and some additives to form a composite phase change cold storage agent, so that it not only has the excellent cold storage performance of ice, but also has the special properties of polymer materials, but the phase change of this kind of cold storage agent The temperature is mostly 0°C ~ 1°C, which is easy to cause low temperature phenomenon during transportation, resulting in ultra-low temperature of transported goods

Description

technical field [0001] The invention belongs to the field of cold chain transportation, and in particular relates to a novel solid phase-change cold storage agent for cold chain transportation at 2-8°C, a preparation method and application thereof. Background technique [0002] Phase-change cooling agent is the cold source for cold storage in the cold chain transportation system, and the temperature requirement in the cold chain transportation of biomedicine is mostly 2-8°C. If the temperature exceeds this range, many vaccines, preparations, drugs, etc. will fail. Therefore, the requirements for the phase change temperature of the phase change cool storage agent are getting higher and higher. The cold storage agents commonly used in the market for 2-8°C cold chain transportation mainly include inorganic cold storage agents, organic cold storage agents and polymer cold storage agents. There are supercooling and phase separation phenomena during the phase transition of inorga...
