Embodiment 1
[0030] Under normal pressure, use tap water as solvent, heat to about 80°C, prepare hot water to make a solution containing 0.1g / 100mL agar powder, then add 1.0mL / 100mL polyethylene glycol while it is hot, stir well and add 3.0g / 100mL of water-absorbent resin combined with polyacrylate and polyvinyl alcohol, stirred and left for 10 minutes to form a gel-like cooling agent. Pack the gel-like cooling agent into bags, put it into a refrigerator at -10℃~-20℃ after cooling, and freeze for more than 12 hours. The phase transition temperature of the cold storage agent is -5.2°C, and the ice pack maintains the temperature below 5°C for about 7.5 hours in an environment of 18°C.
Embodiment 2
[0032] Use tap water as a solvent, heat it to about 50°C, and prepare hot water into a solution containing 0.5g / 100mL magnesium lithium silicate (do not add polyethylene glycol (that is, the amount of polyethylene glycol added is 0 mL / 100mL)) , after fully stirring, add 1g / 100mL polyacrylate water-absorbing resin, and let it stand for 10 minutes after stirring to form a gel-like cooling agent. Pack the gel-like cooling agent into bags, put it into a refrigerator at -10℃~-20℃ after cooling, and freeze for more than 12 hours. The phase transition temperature of the cold storage agent is about 0°C, and the ice pack maintains the temperature below 5°C for about 12 hours in an environment of 18°C.
Embodiment 3
[0034] Use purified water as solvent, heat to boiling (about 100°C), then prepare hot water to make a solution containing 0.5g / 100mL agar powder, fully dissolve, add 2.0mL / 100mL polyethylene glycol while hot, stir well and then add 2.0g / 100mL polyvinyl alcohol water-absorbing resin, after stirring, let it stand for 10 minutes to form a gel-like cooling agent. Pack the gel-like cooling agent into bags, put it into a freezer at -10℃~-20℃ after cooling, and freeze for more than 12 hours. The phase transition temperature of the cold storage agent is -4.0°C, and the temperature is kept below 5°C for about 8.5 hours in an environment of 18°C.
