preparation example Construction
[0044] In order to further optimize the above-mentioned technical scheme, the preparation method of the cold storage agent, the specific steps are as follows;
[0045] S1: Add 2-3 parts of konjac powder and 1-3 parts of polyvinyl alcohol to 90 parts of water, heat to 80°C, and keep stirring for 60 minutes to fully swell to obtain mixed solution A;
[0046] S2: add 2-5 parts of potassium nitrate and 1-3 parts of sodium chloride to 5 parts of water, heat to 40°C, and keep stirring to fully dissolve to obtain mixed solution B;
[0047] S3: add 1-3 parts of borax to 5 parts of water, heat to 40°C, and keep stirring to fully dissolve to obtain a mixed solution C;
[0048] S4: Add the mixed solution B to the mixed solution A, and keep stirring, add the mixed solution C after 3-5 minutes, stir for another 3-5 minutes, cool to room temperature to obtain the cooling agent.
