Abstract

The invention belongs to the application field of reflective materials and products, and in particular relates to a reflective film based on a thermosetting coating and a preparation method thereof. First, aluminum powder and glass powder are melted and blended to protect aluminum better; further, using the function of thermosetting powder coating to easily form a stable film, the glass-protected aluminum powder is ground and dispersed in thermosetting powder coating, sprayed on a high temperature resistant base The film is used as the reflective bottom layer, and then sprayed with a layer of glass beads, cured at high temperature for bonding, and further coated with a hydrophobic self-cleaning coating to obtain a reflective film. In particular, thermosetting powder coatings have a softening process at 120-130°C. The present invention sprays glass microspheres onto the surface of the metal coating by means of this process, and then cures at high temperature, so that the half spherical surface of the glass microspheres is close to the metal layer, and the half spherical surface Fully exposed; thereby replacing the currently difficult-to-control process of plating metal on the hemispherical surface of glass beads, making the preparation of the reflective layer of the reflective film simple and easy to control.

Description

Technical field [0001] The present invention belongs to the field of reflective materials and articles, which relates to a reflective film and preparation method based on a thermosetting coating. Background technique [0002] The reflective film is a prefabricated product with reverse reflected light.
