Abstract

The invention discloses an acrylic color changing film manufacturing method. The method includes steps: taking a base material layer, preparing a mixture A and a mixture B, subjecting the mixture A and the mixture B to methacrylic resin A, and coating the base material layer with the methacrylic resin A to form a coloring layer; preparing a mixture C and a mixture D, subjecting the mixture C and the mixture D to reaction to obtain methacrylic resin B, and coating the coloring layer with the methacrylic resin B to form a functional layer; adopting a metal material for forming a metal layer on the functional layer by means of vacuum evaporation or magnetron sputtering; preparing a mixture E and a mixture F, and subjecting to reaction to obtain an acrylic pressure-sensitive adhesive; coatinga release film with the acrylic pressure-sensitive adhesive to obtain a pressure-sensitive adhesive layer; pressing the pressure-sensitive adhesive layer on the metal layer, stripping the base material layer, and coating one surface of the coloring layer with an anti-doodling layer to obtain an acrylic color changing film. The acrylic color changing film manufacturing method has advantages that ply adhesion of the color changing film is improved, influences on overall appearance due to film layer shedding are avoided, and the self-cleaning performance of the color changing film is improved.

Description

technical field [0001] The invention relates to a color-changing film, in particular to a method for manufacturing an acrylic color-changing film. Background technique [0002] With the improvement of living standards, people's pursuit of beauty and individual needs are getting higher and higher. People are no longer satisfied with just making a decorative film with color changes. Now people require rich colors and high gloss and A certain metal texture, etc. Most of the decorative films on the market are made of PVC and PU materials, and some are PVC and PU mixed with metal coating color-changing films. Although the decorative films of this material have good printability and color printing, but it has certain deficiencies in weather resistance and thermal stability. It is prone to shrinkage and whitening in high-temperature and high-humidity environments, which affects the appearance, and because PVC and PU materials have relatively low adhesion to general metals. Poor, a...
