Cooling gel sheet and preparation method thereof

Abstract

The invention discloses a cooling gel sheet and a preparation method thereof. The cooling gel sheet comprises a cooling gel sheet body, and is characterized in that the cooling gel sheet body is formed by stacking an elastic non-woven fabric (1), a hydrogel layer (2) and an embossed film (3), wherein the elastic non-woven fabric (1) is positioned on the upper layer of the hydrogel layer (2), and the embossed film (3) is positioned on the lower layer of the hydrogel layer (2). According to the invention, the elastic non-woven fabric (1) is taken as an additional liner layer, and hydrogel uniformly coats the elastic non-woven fabric without edge leaving and hydrogel leakage, so that the softness and the attaching property of the cooling gel sheet are increased; the three-point design is adopted, so that the cooling effect is accelerated. The cooling gel sheet is easy to attach and remove, safe and convenient, thus being suitable for people of all ages.

Description

technical field [0001] The invention relates to the technical field of antipyretic patch, in particular to an antipyretic patch and a preparation method thereof. Background technique [0002] Antipyretic patches are accepted by more and more people by virtue of their practicability and convenience. Antipyretic plaster is a physical cooling product, mainly because it contains polymer hydrogel that can concentrate heat into the jelly, and quickly evaporate the water in the gel to take away the heat in the body. It is widely used in children with fever, fever, Suitable for summer and high temperature operation. [0003] Advantages of cooling stickers: [0004] 1. Traditional antipyretics are absorbed by the stomach after being taken orally, and then regulate the physiological functions of the human body to achieve the purpose of cooling down. The unique physical cooling method achieves the effect of zero side effects and avoids the first-pass effect of the liver; [0005] 2...

AI Technical Summary

Problems solved by technology

[0008] Chinese patent CN102166149A discloses an antipyretic patch and its preparation method, which is composed of non-woven fabric, hydrogel layer and plastic film. The antipyretic effect of this antipyretic patch is not ideal and it is easy to fall off

At present, the antipyretic patch on the market uses traditional non-woven fabric as the lining layer. The non-woven fabric is inelastic and has poor softness, and the forehead of the human body has a certain curvature. During use, the right angle of the antipyretic patch is easy to open , so that it falls off by itself in less than 4 hours after use, and the cooling effect is not ideal

Moreover, in order to facilitate the removal of the traditional antipyretic stickers after use, there is an easy-to-remove area (no glue area) on the edge of the non-woven fabric. The easy-to-remove area does not adhere to the human skin, and it is easy to fall off during use.
