Problems solved by technology

The cold source needs to store cold in a low temperature environment before use, and the effect of the fan is not obvious when the ambient temperature is relatively high, and it will cause discomfort when used for a long time
Therefore, there is no technology that is more convenient to use, does not need to be frozen, can be used for a long time, and has a good cooling effect to help people cool down in a high-temperature environment and avoid problems that affect health due to excessive heat obtained by the body from the environment.

Embodiment 1

[0035] This embodiment provides a self-refrigerating cooling sticker, which includes a one-way film packaging bag 2 with a built-in composite adsorbent 1, a composite refrigerant 3, a porous film layer 4 covering the composite refrigerant 3, and the final core from the inside to the outside. The back-adhesive non-woven fabric layer 5 covered by the outer layer. Among them, the composite refrigerant 3 is Na 2 CO 3 10H 2 O, CaCl 2 ·6H 2 O and a mixture of polymeric cold storage material sodium polyacrylate with cold storage function; the porous membrane layer 4 is a chitosan pervaporation membrane modified by layered hydrophilic potassium montmorillonite, with a pore size of 0.6 μm and a porosity of 50 %; composite adsorbent 1 is a mixture of activated carbon and alumina, and the particle size of composite adsorbent 1 is 0.2mm; the average pore diameter of one-way film packaging bag 2 is 0.1mm, mainly to prevent internal substances from leaking and to allow gas and water to ...

Embodiment 2

[0037] Embodiment 2 provides a self-refrigerating cooling sticker. Compared with Embodiment 1, the difference lies in that the pore diameter of the porous membrane layer 4 is 0.8 μm, and the rest is roughly the same as Embodiment 1, and will not be repeated here.

Embodiment 3

[0039] Embodiment 3 provides a self-refrigerating cooling sticker. Compared with Embodiment 1, the difference is that the porosity of the porous film layer 4 is 60%, and the rest is roughly the same as Embodiment 1, so it will not be repeated here.

Abstract

The invention provides a self-refrigeration type cool patch and application thereof. The cool patch sequentially comprises a one-way film packaging bag, a composite refrigerant, a porous film layer and a back patch non-woven fabric layer from inside to outside, wherein the one-way film packaging bag is internally provided with a composite adsorbent, the porous film layer wraps the composite refrigerant, and the back patch non-woven fabric layer wraps the outermost layer. The compound refrigerant comprises a chemical refrigeration substance requiring water to participate in a refrigeration process; by controlling the aperture and porosity of the porous membrane layer, the passing rate of water and moisture can be adjusted, and the reaction rate of a refrigerant is controlled; the internal composite adsorbent and the one-way film packaging bag play a role in one-way moisture conduction. After the self-refrigeration type cool patch is attached to the surface of a human body, moisture in air and sweat gas of the human body penetrate through the film layer and react with the composite refrigerant to absorb heat, the effective cooling effect is achieved, and meanwhile the composite adsorbent on the innermost layer can adsorb moisture mixed in the composite refrigerant and generated gas. The self-refrigeration type cooling patch is controllable in refrigeration effect, long in duration time, free of freezing in advance during use, convenient, rapid and high in practicability.

Description

technical field [0001] The invention relates to the technical field of cooling stickers, in particular to a self-refrigerating cooling sticker and its application. Background technique [0002] When people burn fossil fuels, such as oil, coal, etc., or cut down forests and burn them, a large amount of carbon dioxide will be produced, resulting in greenhouse gases, which are highly transparent to visible light from Long-wave radiation is highly absorptive and can strongly absorb infrared rays in ground radiation, leading to an increase in the temperature of the earth, namely the greenhouse effect. As environmental problems become more and more serious, the continuous accumulation of the greenhouse effect causes global warming. The phenomenon of global warming makes people's living environment worse and worse, especially in summer, the hot weather lasts longer and longer, making people unbearable; after leaving indoor or public closed environments, people will In the natural...
