Problems solved by technology

This anti-counterfeiting method requires a complete set of digital management system in production, and the inquiring party needs a specific identification system. The identification code is intermittent and the protective film is continuous, which means that not every section of the protective film has the anti-counterfeiting identification function. , coding recognition, not suitable for transparent protective film, so we designed an anti-counterfeiting water-based pressure-sensitive adhesive protective film and its preparation method to solve the above problems

Abstract

The invention discloses an anti-counterfeiting waterborne pressure-sensitive adhesive protecting film and a preparation method thereof. The anti-counterfeiting waterborne pressure-sensitive adhesive protecting film comprises the following components in parts by mass: 70-95 parts of soft monomers, 5-20 parts of hard monomers, 2-15 parts of functional monomers, 0.2-2.0 parts of an emulsifier, 0.2-1.5 parts of an initiator, 0.02-1.2 parts of a PH buffer, 0.1-5 parts of luminous aid and 35-140 parts of deionized water. The preparation method comprises the following steps: S1, preparation of the luminous aid; S2, preparation of emulsion; and S3, preparation of an anti-counterfeiting protecting film. In the provided formula, the water is used as a solvent, and the cost is reduced while environmental protection is achieved; and the uniformity and luminous efficiency of the protecting film are good, the anti-counterfeiting protecting film only can show bright visible light color under the illumination of ultraviolet light, anti-counterfeiting checked operation is simple, the cost is low, repeatability and reliability are achieved, a concealed anti-counterfeiting purpose is achieved, and furthermore, the ultraviolet aging resistance of the protecting film can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of pressure-sensitive adhesive protective films, in particular to an anti-counterfeit water-based pressure-sensitive adhesive protective film and a preparation method thereof. Background technique [0002] With the development of society and people's pursuit of exquisite product appearance, the application fields of protective films are becoming more and more extensive, and there are trends such as variety diversification, high quality, product functionality, and customization.
