Problems solved by technology

The requirements for holographic hot stamping film in the fields of tobacco and alcohol packaging and pharmaceutical packaging are mainly good aesthetics, good anti-counterfeiting, and good hot stamping performance. There is no special requirement for high temperature resistance of hot stamping film; but for the field of plastic hot stamping, ordinary holographic hot stamping Membrane fails to meet requirements
This is because hot stamping on the surface of plastic parts generally requires a relatively high hot stamping temperature, generally between 200-300°C, and ordinary holographic hot stamping films will have apparent abnormalities such as hot stamping, whitening, fogging and flooding; and because High-temperature molding, the microstructure of the holographic pattern is damaged, which will cause the distortion of the holographic pattern and greatly reduce the decorative effect

Abstract

The embodiment of the invention provides a high-temperature-resistant holographic gold stamping film, a gold stamping plastic part and a preparation method, and relates to the field of gold stamping films. The high-temperature-resistant holographic gold stamping film comprises a base film, a release layer, a protective layer, a mold pressing layer, a metal coating and an adhesive layer which are sequentially stacked from bottom to top, the surface, close to the metal coating, of the mold pressing layer is provided with a holographic pattern microstructure, and coatings corresponding to the protective layer and the mold pressing layer both contain polyhydroxy acrylic resin, amino resin and isocyanate. The dosage ratio of the amino resin to the isocyanate in the coating corresponding to the protective layer is (2-4):1, and the dosage ratio of the amino resin to the isocyanate in the coating corresponding to the mold pressing layer is (0.5-1):1. The high-temperature-resistant holographic gold stamping film has excellent physical and chemical resistance, can resist high temperature hot stamping and mold pressing, and meets higher decoration requirements in the plastic gold stamping field.

Description

technical field [0001] The present application relates to the field of bronzing film, in particular, to a high temperature resistant holographic bronzing film, a bronzing plastic part and a preparation method. Background technique [0002] At present, there are some hot stamping films used to decorate the plastic surface, such as hot stamping text information, decorative strips, etc. on the casing of home appliances, but there are generally problems such as low hot stamping temperature, insufficient physical and chemical resistance, and insufficient brightness. Disadvantages, and the main decorative effect of this type of hot stamping film is the anodized aluminum layer, which cannot carry holographic patterns, the decorative effect is poor, and it cannot meet the higher decorative needs of users. [0003] The structure of the holographic hot stamping film usually includes a base film layer, a release layer, an imaging layer, a metal coating layer and an adhesive layer. It c...
