A kind of ultra-mirror anti-scratch transfer film and preparation method thereof

Abstract

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. The preparation of the super-mirror anti-scratch transfer film includes the following preparation steps: taking a PET film; mixing water-based polyurethane, an alcohol organic solvent and water Mixed and stirred evenly by weight, is modulated into water-based release coating; the prepared water-based release coating is coated on the surface of the PET film to form a water-based release coating; after the water-based release coating is dried, it is a water-based release layer, A PET film semi-finished product loaded with a water-based release layer is obtained; the outer surface of the water-based release layer is coated with an information coating to form an information coating; the surface of the information coating is sequentially provided with a vacuum aluminized layer and an adhesive layer, A finished super-mirror anti-scratch transfer film is obtained. The super-mirror anti-scratch transfer film of the invention has strong scratch resistance, high specular gloss, simple preparation process and high 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
