Bronzing transfer film process

Abstract

The invention discloses a process for a gold-stamped transfer film and relates to the technical field of a gold stamping process. The process comprises the following technological procedures: (1) forming a PET (Polyethylene Terephthalate) base film; (2) forming a release layer; (3) forming an information layer; (4) forming an aluminum plated layer; (5) forming a back glue layer; (6) slitting a finished product; the process comprises the following solvents: ethyl ester, butanone, cyclohexanone and methylbenzene; the process comprises the following raw materials in solid content: 30% of LX-51M-3, 30% of LX-49M, 50% of PET-261, 50% of PET251H and 20% of BJ-30A-1; the PET base film is a PET transfer film; the release layer is an LX-51M-3 release layer; the information layer is a color layer including double components which are namely PET-261 and PET251H; the back glue layer is BJ-302 and 88 glue. The process for the gold-stamped transfer film, disclosed by the invention, has the beneficial effects of being clear in print after stamping, angular, bright, free of pasting, scratch and drop and the like.

Description

technical field [0001] The invention relates to a bronzing process technology, in particular to a bronzing transfer film process. Background technique [0002] At the same time that my country's economy is developing rapidly, related science and technology have also made great progress. Among them, the development of bronzing technology is more prominent. Bronzing technology is an important means of decoration for consumer electronics products. It has been used in the electronics industry for nearly forty years. In the development process in recent years, bronzing technology has made new progress, and the scope of application has been further expanded. At present, bronzing technology has become an important metal effect surface finishing method, which plays a promotional role in packaging. Also getting bigger and bigger. The hot stamping process uses the principle of heat transfer to transfer the aluminum layer in the anodized aluminum to the surface of the substrate to for...

Problems solved by technology

If the temperature is too low, the adhesive layer and release layer of the anodized aluminum cannot be fully melted, and the anodized aluminum cannot be fully transferred during hot stamping, resulting in the failure of hot stamping; if the temperature is too high, the coating deformation is serious, and it is easy to cause inaccurate registration, graphics and text Problems such as sticky board, blurred handwriting, discoloration of anodized aluminum, etc.; too much pressure, easy to imprint unclear, not bright, paste board, pictures and texts are dizzy, faint; too small pressure, easy to stamp not firm, fall off, Flower version, the edges and corners are not clear; if the speed is too fast, the separation force and peeling force of the foil layer of the anodized aluminum will not match, resulting in unstable hot stamping; dull
