Abstract

The invention relates to a film coating product in the holographic anti-counterfeiting printing industry, and in particular relates to a laser bronzing electrochemical aluminum modified release material. The laser bronzing electrochemical aluminum modified release material provided by the invention is used for coating an electrochemical aluminum release layer, so that the hot stripping force of continuous hot stamping can be effectively reduced, the stability of high-speed hot stamping is ensured and the speed of hot stamping is increased. A composition of the laser bronzing electrochemical aluminum modified release material consists of the following components in parts by mass: 25-35 parts of melamine resin, 1-5 parts of fluorinated epoxy resin, 1-5 parts of ethanol, 25-35 parts of butanone, 20-40 parts of butyl ester and 20-50 parts of methylbenzene. After the release layer is coated out by using the laser bronzing electrochemical aluminum modified release material, no grain trace is formed, a phenomenon of a wax ring is avoided, the hot stamping stripping force after fluorine modification is effectively reduced, and the hot stamping speed is increased to 5000-6000 pieces per hour.

Description

technical field [0001] The invention relates to a film-coated anodized aluminum product in the holographic anti-counterfeiting printing industry, in particular to a laser bronzing anodized aluminum modified release material. Background technique [0002] Traditional laser bronzing anodized aluminum is generally realized by using PET film as the carrier base film, and coating the release layer, laser information layer, aluminum layer, and adhesive layer on it in sequence. The function of the release layer is After hot stamping, the coatings are separated from the base film; however, due to the poor separation and stability of the release agent used in the current anodized aluminum coatings, the hot stamping processing speed cannot be further improved, and it may even directly affect the appearance of hot stamping , Limiting the development of the electrochemical aluminum manufacturing industry. The Chinese Invention Patent No. 200910192558.3 ​​discloses a preparation method ...
