Super-specular anti-scraping transfer film and preparation method thereof

Abstract

The invention relates to the technical field of transfer films, in particular to a super-specular anti-scraping transfer film and a preparation method thereof. The preparation method of the super-specular anti-scraping transfer film comprises the following steps that a PET (Polyethylene Terephthalate) thin film is taken; waterborne polyurethane, an alcohol organic solvent and water in parts by weight are mixed and stirred uniformly, and blended into waterborne release dope; the surface of the PET thin film is coated with the blended waterborne release dope to form a waterborne release coating layer; the waterborne release coating layer is dried to be a waterborne release layer; a semifinished PET thin film loaded with the waterborne release layer is prepared; the outer surface of the waterborne release layer is coated with information coating layer dope to form an information coating layer; a vacuum aluminum coated layer and a gum application layer are arranged on the surface of the information coating layer sequentially; and the finished super-specular anti-scraping transfer film is prepared. The super-specular anti-scraping transfer film is high in scraping resistance, and high in specular glossiness, and the preparation method of the super-specular anti-scraping transfer film is simple in technology and high in production efficiency.

Description

technical field [0001] The invention relates to the technical field of transfer films, in particular to a super-mirror anti-scratch transfer film and a preparation method thereof. Background technique [0002] The transfer film is an intermediate carrier, which exists on the transfer paper base or plastic base, carries the printed or printed pattern, and is used to transfer to a layer of chemical elastic film on the printed article. It is widely used in advertising, decoration etc. At present, in order to achieve the functions of rich color, fineness, brilliance, durability, wear resistance and high temperature resistance of leather, it is generally necessary to print on the surface of leather. Due to the unevenness of leather products, transfer technology is generally used in the process of selecting printing. Leather The transfer film came into being. When in use, the leather transfer film is hot-bonded with artificial leather, PU leather and genuine leather by pressing a...

Problems solved by technology

[0003] The Chinese invention patent with application number 200910052388.9 discloses a paint transfer film for decoration, which consists of five layers from outside to inside: bearing layer, release layer, printing layer, paint layer and adhesive layer, among which, The release layer is coated with a release agent. The release agent is one or more of water-based wax emulsion, acrylic emulsion and pure acrylic emulsion. However, the film-forming properties of water-based wax emulsion, acrylic emulsion and pure acrylic emulsion are poor. , no recoatability, the release layer formed by coating is thin, not scratch-resistant, and the mirror gloss is low, and the decorative effect is poor

[0004] The Chinese invention patent with application number 201210262380.7 discloses a mirror transfer film and its production method and application. The mirror transfer film includes a carrier layer, a release layer, a transparent protective layer, a color layer, Aluminum layer, connecting layer and adhesive layer, among which, the release layer is composed of cellulose resin containing silicone oil. The release layer composed of this cellulose resin is prone to rainbow light, and there is a certain degree of haze, the surface brightness is low, and the mirror effect Not strong, it is difficult to meet the increasing decoration needs of the majority of users

[0005] In summary, the problems of poor scratch resistance and low mirror brightness of leather transfer film need to be solved urgently
