Problems solved by technology

[0005] In order to solve the problem that the existing electronic temperature detection equipment in the cold chain transportation has high manufacturing cost and can only monitor the temperature of the environment where the target item is transported but cannot monitor the temperature of a single target item, the technical solution adopted is: An irreversible temperature-sensitive sticker, comprising: a substrate layer, a temperature-sensitive layer, a color-developing layer, a protective layer and an isolation layer, the edge of the substrate layer is partially or completely connected to the edge of the protective

Embodiment 1

[0030] Such as figure 1 As shown, on the one hand, the present invention provides an irreversible temperature-sensitive sticker, comprising: a substrate layer 1, a temperature-sensitive layer 2, a color-developing layer 3, a protective layer 4 and an isolation layer 5, and the edge of the substrate layer 1 is connected to the protective layer. Part or all of the edges of layer 4 are connected together by hot melt adhesive or other glues. The thickness of the substrate layer 1 is selected according to actual needs. In this embodiment, a thickness of 0.02mm-0.1mm is selected. There is the temperature-sensitive layer 2, and its adhesive material can be selected from one or a combination of hot melt adhesive, pressure-sensitive adhesive, and TPU glue, and the temperature-sensitive layer 2 is made of an absorbent material, such as: oil-absorbing Paper, oil-absorbing cotton, oil-absorbing felt, etc., the temperature-sensitive color-changing ink 21 is adsorbed in the temperature-sens...

Embodiment 2

[0038] Such as Figure 5 As shown, the difference between this embodiment and the first embodiment is that the edges of the substrate layer 1 and the edges of the protective layer 4 are all connected. That is to say, the isolation layer 5 is sealed between the substrate layer 1 and the protective layer 4. When the temperature-sensitive sticker needs to be used, it is necessary to manually tear the temperature-sensitive sticker with tools such as scissors or with bare hands to facilitate the isolation layer. 5 Extracted openings.

Embodiment 3

[0040] Such as Image 6 As shown, the difference between this embodiment and the first embodiment is that: the same end of the substrate layer 1 and the protective layer 4 is provided with a plurality of easy-tear lines 6 formed of easy-tear holes. When the isolation layer 5 needs to be pulled out, it is only necessary to tear an opening of the temperature-sensitive sticker along the easy-tear line 6, and then pull out the isolation layer 5.

Abstract

The invention relates to an irreversible temperature-sensitive sticker, which comprises a substrate layer, a temperature-sensitive layer, a color developing layer, a protective layer and an isolatinglayer, wherein the edge of the substrate layer is partially or completely connected with the edge of the protective layer, the temperature-sensitive layer is arranged on the inner side of the substrate layer, temperature-sensitive color-changing ink is adsorbed in the temperature-sensitive layer, the color developing layer is arranged on the inner side of the protective layer, the color developinglayer is made of an adsorption material, the temperature-sensitive layer and the color developing layer are partially overlapped, and the isolation layer is arranged between the substrate layer and the protective layer. The irreversible temperature-sensitive sticker and the temperature-sensitive color-changing ink provided by the invention have the advantages of high sensitivity, strong stabilityand simple device preparation process, and also have the characteristics of environment-friendly and pollution-free raw materials and process and irreversible color change of a target object during temperature measurement, and can be widely applied to the fields of cold chain preservation of medicines, blood products, biological products, vaccines, fruits and vegetables and the like.

Description

technical field [0001] The invention relates to the field of temperature monitoring equipment, in particular to an irreversible temperature-sensitive sticker and temperature-sensitive color-changing ink. Background technique [0002] When transporting and storing goods, some goods with high temperature requirements, such as medicines that need to be frozen or refrigerated, once they reach a certain temperature, the quality of the goods will decline or even fail completely. It is necessary to intuitively understand whether the object has reached the threshold value during transportation and storage, so as to avoid the situation where the temperature of the object is accidentally higher than the threshold value and then lower than the threshold value, so that people may misjudge the storage environment of the object, so as to facilitate the storage of the object And unmanned monitoring of the transportation environment. The traditional cold chain uses electronic temperature s...
