Technical Field
The utility model relates to a temperature monitoring antifalsification label technical field, concretely relates to temperature monitoring antifalsification label that can sign.
Background
Currently, a large number of temperature sensitive products are stored, transported and used under cold chain conditions. If the product is separated from the cold chain environment, the product properties are changed, thereby endangering the personal safety of the product user. Therefore, there is a need for a label with temperature monitoring capability that can be attached to product packaging to indicate whether various heat sensitive products have deteriorated or failed during storage or transportation due to temperatures exceeding safe storage and transportation temperatures.
The existing temperature detection monitoring label does not have an anti-counterfeiting function and is easy to be counterfeited and replaced by lawbreakers. If the product is separated from the cold chain environment in the using process, the temperature detection label shows that the product exceeds the safe storage and transportation temperature, but a lawbreaker can remove the temperature detection label, replace the temperature detection label with a new temperature detection label or a forged temperature detection label, and cheat a consumer to profit from the temperature detection label by deteriorated and invalid products, so that the rights and interests of consumers are damaged. In addition, the existing temperature monitoring label is not easy to store, and needs to be stored in a refrigerated mode before being used, or needs to be stored in two parts which are combined with each other when being used.
Therefore, aiming at the defects that most of the existing temperature-sensitive labels have limited anti-counterfeiting functions, are insufficient in personalized elements, and need to be stored in a cold storage mode before being used, the temperature-sensitive labels which are convenient to use, cannot be taken off and replaced, can be stored at normal temperature before being used and can be used for monitoring the heat history of heat-sensitive articles are urgently needed to be researched in the field, so that the temperature-sensitive labels can be conveniently used for storage and transportation monitoring of the heat-sensitive articles.

the glue layer is prepared by coating an adhesive containing a temperature-change dye on the aluminum layer, and the temperature-change dye can change color irreversibly when the temperature exceeds a set value; the release layer is a thin film with a release effect;
before the label is started, the temperature monitoring function does not work, and the label can be stored at room temperature; after the label is started, the release layer is torn, the glue layer is adhered to the surface of an object, the temperature monitoring function can be started and activated by slightly pressing the color-changing signature area, when the ambient temperature of the label exceeds a set value, the temperature-changing adhesive which is transferred to the color-changing signature area can generate an irreversible color phenomenon, the color is gradually deepened, and the temperature-changing adhesive can be compared with the color of the contrast color area to indicate whether the accumulated heat born by the object exceeds a safety range.
Furthermore, the carrier layer is a transparent plastic film, and the thickness of the carrier layer is 10-50 mu m.
Furthermore, the color-changing signature area is a white porous polyester film, the thickness of the color-changing signature area is 10-50 mu m, and the color-changing signature area can be used for handwriting signature or stamping to show the use.
Furthermore, the organic coating with high brittleness adopted by the holographic information layer is epoxy acrylic resin or epoxy polyurethane resin, and the thickness of the coating is 1-3 microns.
Further, the coating thickness of the adhesive containing the temperature-change dye in the glue layer is 1-3 mu m, the adhesive is a polyurethane temperature-change dye adhesive and is prepared by mixing the polyurethane adhesive and the temperature-change dye, and the mixing proportion is determined according to the numerical value of the temperature required to be monitored by the label.
Further, the preparation process of the polyurethane adhesive is as follows:
mixing the components in a mass ratio of 1: 0.01-1: 0.1 of polyurethane resin ETERANE 89641BA and PDMS organic silicon modifier are subjected to ball milling and uniform mixing, diluted by a solvent and added with a flatting agent and a defoaming agent to obtain the polyurethane adhesive;
