Embodiment 1

[0015] as attached figure 2 As shown, a 2-8 ℃ constant temperature ice pack is composed of an inner layer 12 and an outer layer 11, the outer layer 11 completely wraps the inner layer 12, and the outer layer 11 is made of 1-5 parts by weight of high molecular polyacrylamide, pure It is composed of 10-50 parts by weight of water, 5-40 parts by weight of alkylphenol polyoxyethylene ether, and 3-15 parts by weight of polyoxyethylene sorbitol ester. The gel layer has a solidification point of +5°C, plays a slow-release function, and isolates low temperature. The inner layer 12 is a -16°C constant temperature layer composed of 1-5 parts by weight of polyvinyl alcohol, 20-30 parts by weight of ethylene glycol, and 30-70 parts by weight of pure water. The low-temperature energy is stored in the inner layer, and the low temperature is isolated when it passes through the outer layer at the release temperature, and the contact object is kept at a constant temperature of 2-8°C using ice...

[0017] as attached image 3 As shown, a 2-8 ℃ constant temperature ice pack is composed of an inner layer 22 and an outer layer 21, the outer layer 21 is divided into upper and lower layers to surround the inner layer 22, and the outer layer 21 is made of 1-5 parts by weight of high molecular polyacrylamide , 10-50 parts by weight of pure water, 5-40 parts by weight of alkylphenol polyoxyethylene ether, 3-15 parts by weight of polyoxyethylene sorbitol ester, the gel layer with a freezing point of +5°C plays a slow-release role and isolates low temperature. The inner layer 22 is a -16°C constant temperature layer composed of 1-5 parts by weight of polyvinyl alcohol, 20-30 parts by weight of ethylene glycol, and 30-70 parts by weight of pure water. The low-temperature energy is stored in the inner layer, and the low temperature is isolated when it passes through the outer layer at the release temperature, and the contact object is kept at a constant temperature of 2-8°C using i...

Embodiment 3

[0019] as attached Figure 4 As shown, a 2-8 ℃ constant temperature ice pack is composed of an inner layer 32 and an outer layer 31, the outer layer 31 is composed of 1-5 parts by weight of high molecular polyacrylamide, 10-50 parts by weight of pure water, alkylphenol polyoxygen It consists of 5-40 parts by weight of vinyl ether and 3-15 parts by weight of polyoxyethylene sorbitol ester. The solidification point of the gel layer is at +5°C, which acts as a slow release and isolates low temperature. The inner layer 32 is a -16°C constant temperature layer composed of 1-5 parts by weight of polyvinyl alcohol, 20-30 parts by weight of ethylene glycol, and 30-70 parts by weight of pure water. The low-temperature energy is stored in the inner layer, and the low temperature is isolated when it passes through the outer layer at the release temperature, and the contact object is kept at a constant temperature of 2-8°C using ice packs.

Abstract

The present invention discloses a 2-8 DEG C constant temperature ice bag, which comprises an inner layer and an outer layer, wherein the components of the outer layer comprise, by weight, 1-5 parts of polymer polyacrylamide, 10-50 parts of purified water, 5-40 parts of alkyl phenyl polyoxyethylene ether, and 3-15 parts of polyoxyethelene sorbitol ester, the solidifying point of the components of the outer layer is at the +5 DEG C gel layer, the components of the inner layer comprise, by weight, 1-5 parts of polyvinyl alcohol, 20-30 parts of ethylene glycol, and 30-70 parts of purified water, and the solidifying point of the components of the inner layer is at the -16 DEG C constant temperature layer. According to the 2-8 DEG C constant temperature ice bag, the ice point of the outer layer is at the temperature of +5 DEG C, and the outer layer is adopted as the thermal insulation layer, such that it is ensured that the inner layer can not directly contact the article so as to ensure uniformity of the temperature; due to the special components of the outer layer, the temperature of the outer layer can not be more than or less than +5 DEG C; and the inner layer is adopted as the cold storage layer, slow cooling air release can be ensured through transfer by the outer layer, such that it is ensured that the cold storage time of the 2-8 DEG C constant temperature ice bag is 4 times the cold storage time of the ordinary ice bag.

Description

technical field [0001] The invention relates to an ice pack, in particular to a 2-8°C constant temperature ice pack. Background technique [0002] The ice packs currently on the market are all ice packs with zero degrees as the freezing point or below zero as the ice pack point, and the temperature is often too low during use, and the temperature of the ice packs cannot be controlled. Contents of the invention [0003] The object of the present invention is to provide a constant temperature ice pack capable of controlling the temperature at 2-8°C. [0004] The present invention is achieved like this: [0005] A 2-8°C constant temperature ice pack, comprising an inner layer and an outer layer, the outer layer consists of 1-5 parts by weight of high molecular weight polyacrylamide, 10-50 parts by weight of pure water, 5 parts by weight of alkylphenol polyoxyethylene ether -40 parts by weight, composed of 3-15 parts by weight of polyoxyethylene sorbitol ester, the freezing ...
