Embodiment 1

[0041] A temperature-sensitive color-changing and heat-dissipating sticker is composed of a temperature-sensitive color-changing ink layer 1, a non-woven fabric layer 2, a hydrogel layer 3, and an embossed film layer 4. The temperature-sensitive color-changing ink layer 1 contains two kinds of inks, One is blue thermochromic ink, which changes from blue to colorless at 29°C; the other is orange thermochromic ink, which changes from orange to colorless at 31°C. The blue thermochromic ink and the orange thermochromic ink are printed on the upper surface of the non-woven fabric layer 2 by a flexographic printing process at intervals, and can be printed into various patterns, such as cartoon images that children like to make heat-relieving stickers It is more beautiful and popular with children. The hydrogel layer 3 is coated on the lower surface of the non-woven fabric layer 2, the embossed film 4 is attached to the other side of the hydrogel layer 3 opposite to the non-woven fabr...

Embodiment 2

[0061] A temperature-sensitive color-changing and heat-dissipating sticker is composed of a temperature-sensitive color-changing ink layer 1, a non-woven fabric layer 2, a hydrogel layer 3, and an embossed film layer 4. The temperature-sensitive color-changing ink layer 1 contains two kinds of inks, One is blue thermochromic ink, which changes from blue to colorless at 29°C, and the other is orange thermochromic ink, which changes from orange to colorless at 31°C. The blue thermochromic ink and the orange thermochromic ink are printed on the upper surface of the non-woven fabric layer 2 at intervals by a flexographic printing process. The hydrogel layer 3 is coated on the lower surface of the non-woven fabric layer 2, the embossed film 4 is attached to the other side of the hydrogel layer 3 opposite to the non-woven fabric layer, and the embossed film is a CPP film. When in use, only need to uncover the embossed film 4 and stick the hydrogel layer 3 directly on the forehead.

Abstract

The invention discloses a thermochromic fever cooling patch and a manufacturing method thereof. The thermochromic fever cooling patch is composed of a thermochromic ink layer (1), a non-woven fabric layer (2), a hydrogel layer (3) and an embossing film layer (4). The thermochromic ink layer (1) is printed on the upper surface of the non-woven fabric layer (2). The lower surface of the non-woven fabric layer (2) is coated with the hydrogel layer (3). The embossing film layer (4) is stuck to the other face of the hydrogel layer (3). The thermochromic ink layer (1) contains two kinds of ink, namely blue thermochromic ink and orange thermochromic ink, wherein the blue thermochromic ink changes to be colorless from blue at 29 DEG C, and the orange thermochromic ink changes to be colorless from orange at 31DEG C. The thermochromic ink is arranged on the non-woven fabric layer of the fever cooling patch, the fever cooling effect can be judged based on the ink color changes, and the thermochromic fever cooling patch is convenient to use.

Description

Technical field [0001] The invention relates to the technical field of antipyretic stickers, in particular to a temperature-sensitive discoloration antipyretic paste and a preparation method thereof. Background technique [0002] With its practicality and convenience, antipyretic stickers are accepted by more and more people. The antipyretic patch is a physical cooling product, mainly because it contains a polymer hydrogel that can concentrate heat to the jelly, and quickly evaporates the water in the gel to take away the heat in the body. It is widely used to reduce fever in children. Conditions such as summer elimination and hot work. [0003] Advantages of antipyretic stickers: [0004] 1. Traditional antipyretics are absorbed through the stomach and adjust the physiological functions of the human body to achieve the purpose of cooling down. The drug components will reach the internal organs; while the antipyretic patch is an external patch, which is attached to the body surface...
