AI Technical Summary

Technical Problem

The existing building materials protective film has poor metallic gloss, low film surface hardness, and easy scratches and extrusion marks on the surface, resulting in poor aesthetic effect and short service life.

Method used

By stacking a photocuring layer, a metal layer, an adhesive layer and a resin film on the base film, the specific steps include applying a photocuring material to light cure on one side of the base film, performing corona treatment on the other side and plating metal, and then applying the adhesive layer and the resin film.

Benefits of technology

It realizes the high metallic gloss, strong film surface hardness and good scratch resistance of the metal film, which significantly improves the aesthetic effect and service life.

Abstract

The invention discloses a metal film and a preparation method and application thereof. The metal film comprises a base film; a photocuring layer is superposed on one surface of the base film; a metal layer, a bonding layer and a resin film are sequentially stacked on the other surface of the base film; and the resin film is in contact with the decorative surface. The metal film is good in metallic luster, high in film surface hardness and excellent in scratch resistance and friction resistance, can be used as a building material protective film, is attractive, improves the wear resistance of a product and prolongs the service life. The preparation method of the metal film is simple and easy to operate.
