Pressure-sensitive adhesive tamper label material and preparation method thereof

Abstract

The invention discloses a pressure-sensitive adhesive tamper label material and a preparation method thereof, and relates to the technical field of label material preparation. The pressure-sensitive adhesive tamper label material comprises the following raw materials in parts by weight: 60-80 parts of a solvent type methyl vinyl silicone oil ethyl acetate solution, 1-5 parts of a cross-linking agent, 3-5 parts of a catalyst, 10-13 parts of glue, 20-30 parts of a high-viscosity acrylic pressure-sensitive adhesive and 8-10 parts of an isocyanate curing agent. The glue can be attached to silicone oil through blending of a silicone oil formula in the preparation process, the glue can easily fall off to a steel plate after making contact with the steel plate, the anti-dismantling effect is achieved, silicone oil release treatment is conducted on part of the area on a gluing face, the part of glue can fall off to an attached object after a label is torn up, and thus the anti-dismantling effect is achieved; therefore, the tamper label material can be widely applied to the electronic industry needing tamper labels. According to the invention, the silicone oil is applied to a part of area of a PET original film, the glue has certain cohesion, and the glue is correctly selected, so that the glue does not take glue beside when being removed to the steel plate.

Description

technical field [0001] The invention relates to the technical field of label material preparation, in particular to a pressure-sensitive adhesive anti-tamper label material and a preparation method thereof. Background technique [0002] The full name of pressure-sensitive adhesive is pressure-sensitive adhesive, also commonly known as self-adhesive, referred to as pressure-sensitive adhesive. Pressure-sensitive adhesive products include three categories: pressure-sensitive adhesive tape, pressure-sensitive adhesive label paper, and pressure-sensitive film. Their full name is pressure-sensitive adhesive tape, pressure-sensitive adhesive label paper, pressure-sensitive adhesive sheet, commonly known as tape, self-adhesive label paper, pressure-sensitive film. This component has been adjusted to achieve better performance of the product. As the trade between companies and the communication between people become closer and closer, the anti-tamper label as a kind of anti-counter...

Problems solved by technology

[0003] Pressure-sensitive adhesive is a commonly used adhesive in labels. However, the anti-counterfeiting effect of labels using pressure-sensitive adhesives as adhesives is average during use, which is related to the poor physical properties of pressure-sensitive adhesives such as initial tack, peel strength, and stickiness. , to this end, we propose a pressure-sensitive adhesive tamper-evident label material and its preparation method to solve the above problems
