Problems solved by technology

[0002] At present, ice packs are mostly used for physical cooling in medicine or home health care. Ice packs dissipate heat quickly during use, and are not suitable for the elderly and weak. Storage requires a frozen environment, and it takes time to prepare. Because it is solid and lacks flexibility, it cannot be in contact with the skin to the maximum area, and the comfort is poor
Most other types of cold preservation agents also have similar shortcomings such as complicated preparation, strict storage environment, low freezing point temperature, and short rewarming time (usually 1 to 2 hours).

Embodiment 1

[0020] Under the condition of a temperature of 24 degrees, 180 grams of bentonite with a particle size of 100 to 120 meshes was first wetted with water in a mixer, and then stirred evenly. Then, 800 grams of sodium polyacrylate diluted with water was mixed with the wetted bentonite. Then, add 410 grams of glycerin, 410 grams of absolute ethanol and a salt solution that contains 100 grams of table salt diluted with water. Continue to stir until the raw material becomes a paste, add 400 grams of styrene-butadiene emulsion with a concentration of 40 wt%, and stir. Finally, 100 grams of bamboo charcoal with a particle size of 80 to 150 meshes was added, fully stirred until uniform, and the cooling agent A was obtained. The total amount of water used in the whole process is 980 grams.

[0021] Store the cooling agent A in the refrigerator, cool to -20 degrees, take out the cooling agent A from the refrigerator and pack it with a flexible packaging bag. Apply the packaged cold-pr...

Embodiment 2

[0023] Under the condition of a temperature of 23 degrees, 150 grams of bentonite with a particle size of 80 to 150 meshes was first wetted with water in a mixer, and then stirred evenly. Then, 900 grams of sodium polyacrylate diluted with water was mixed with the wetted bentonite. Then, add 380 grams of glycerin, 400 grams of absolute ethanol and a salt solution diluted with water containing 80 grams of table salt. Continue to stir until the raw material becomes a paste, then add 380 grams of styrene-butadiene emulsion with a concentration of 40 wt%, and stir. Finally, 80 grams of bamboo charcoal with a particle size of 80 to 150 meshes was added, fully stirred until uniform, and the cooling agent B was obtained. The total amount of water used in the whole process is 950 grams.

[0024] Store the cryogenic agent B in the refrigerator, cool to -20°C, take out the cryogenic agent A from the refrigerator and pack it in a flexible packaging bag. Apply the packaged cold-preserv...

Embodiment 3

[0026] Under the condition of a temperature of 23 degrees, 200 grams of bentonite with a particle size of 80 to 150 meshes was first wetted with water in a mixer, and then stirred evenly. Then, 950 grams of sodium polyacrylate diluted with water was mixed with the wetted bentonite. Then, add 420 grams of glycerin, 430 grams of absolute ethanol and a salt solution diluted with water containing 120 grams of table salt. Continue to stir until the raw material becomes a paste, add 420 grams of styrene-butadiene emulsion with a concentration of 40 wt%, and stir. Finally, 140 grams of bamboo charcoal with a particle size of 80 to 150 meshes was added, fully stirred until uniform, and the cooling agent C was obtained. The total amount of water used in the whole process is 1100 grams.

[0027] Store the cryogenic agent C in the refrigerator and cool it down to -20°C, take out the cryogenic agent A from the refrigerator and pack it in a flexible packaging bag. Apply the packaged col...

Abstract

The invention relates to a cold preserving agent and a preparation method thereof. The cold preserving agent comprises bentonite, polyacrylate, glycerol, absolute alcohol, water, salt, butylbenzene emulsion and bamboo charcoal powder. The cold preserving agent is ice free at a temperature of -20 DEG C and has long cold preserving time more than 4h, and can be prepared at a normal temperature. Theinvention has better effect on the aspects of medicinal cold treatment, family health and the like.

Description

technical field [0001] The invention relates to a cold preservation agent and a preparation method thereof, in particular to a cold preservation agent which can be prepared at normal temperature and has a long-term cold preservation effect and a preparation method thereof. Background technique [0002] At present, ice packs are mostly used for physical cooling in medicine or home health care. Ice packs dissipate heat quickly during use, and are not suitable for the elderly and weak. Storage requires a frozen environment, and it takes time to prepare. Because it is solid and lacks flexibility, it cannot be in contact with the skin to the maximum area, and the comfort is poor. Most other types of cold preservation agents also have similar shortcomings such as complicated preparation, strict storage environment, low freezing point temperature, and short rewarming time (usually 1 to 2 hours). Contents of the invention [0003] Therefore, the present invention provides a cooli...
