Example Embodiment

[0037] Example one

[0038] This embodiment provides a refrigerant, including the following components, in grams by weight:

[0039]

[0040] The refrigerant is prepared by the following method: Weigh 2g powder graft copolymer, 0.5g sodium carboxymethylcellulose, 0.5g polyethylene oxide, 0.5g sodium sulfate and mix them in a beaker, then add 400g water into the beaker, And use a glass rod for stirring, so that all kinds of substances are uniformly mixed, and the refrigerant is obtained. Starch graft copolymer has the characteristics of abundant raw materials and high water absorption rate.

Example Embodiment

[0041] Example two

[0042] This embodiment provides a refrigerant, including the following components:

[0043]

[0044] The refrigerant is prepared by the following method: Weigh 3g of modified cellulose resin, 0.5g of sodium carboxymethylcellulose, 1g of polyethylene oxide, and 2g of sodium sulfate and mix them in a beaker, and then add 430g of water to the beaker. And use a glass rod for stirring, so that all kinds of substances are uniformly mixed, and the refrigerant is obtained. Cellulose modified resin has the advantages of abundant raw materials and easy biodegradation.

Example Embodiment

[0045] Example three

[0046] This embodiment provides a refrigerant, including the following components, in grams by weight:

[0047]

[0048] The refrigerant is produced by the following method: Weigh 6g of vinyl acetate copolymer, 2g of sodium carboxymethylcellulose, 1.5g of polyethylene oxide, and 5g of sodium sulfate and mix them in a beaker, and then add 470g of water to the beaker. And use a glass rod for stirring, so that all kinds of substances are uniformly mixed, and the refrigerant is obtained. Vinyl acetate copolymer has high strength after absorbing water, which can improve the mechanical properties of the refrigerant and prevent external impact.

Abstract

The invention provides a refrigerating ice bag, a refrigerant and a preparation method of the refrigerant, and belongs to the technical field of refrigerating articles. The refrigerating ice bag comprises the refrigerant and a bag body. The refrigerant is sealed in the bag body. The refrigerant can be frozen into solid to be used by cooling the refrigerating ice bag. The refrigerant in the refrigerating ice bag has a high cold storage function and is slow in chilling, the initial cooling efficiency is high, and the temperature can be lowered quickly. The cooling effect lasts for a long time, the problem that the refrigerating ice bag is frequently replaced can be greatly reduced, and use cost of the refrigerating ice bag is lowered.

Description

technical field [0001] The invention relates to the technical field of refrigerated supplies, in particular to a refrigerated ice bag, a refrigerant and a manufacturing method thereof. Background technique [0002] China's cold chain is still in the initial stage of development, with weak facilities and equipment, and a large gap compared with developed countries. The development of my country's fresh food market mainly began with the government's vigorous promotion of the "agricultural reform to supermarkets". With the advantages of comfortable shopping environment, cheap prices, fresh products, and rich categories, fresh food supermarkets have gradually become the trend of fresh food retail channels. However, judging from the data of the China Chain Store and Franchise Association, there are still many areas for improvement in my country's fresh food supermarkets. Its industry is at a relatively low level in terms of low-temperature cold storage, low-temperature transpor...
