A kind of preparation method and application of gradual color metallic sense TPU film

Abstract

The invention discloses a method for preparing a gradual color metallic TPU film, and relates to a method for preparing a material. By coating and scraping silver paste on a release paper, drying it and laminating it with the first TPU film, at least two The color ink is printed on the second TPU film, and finally the side of the first TPU film with the silver layer is bonded to the side of the second TPU film with the progressive color layer to form this gradient color metallic TPU film. The metallic texture of the film The layer and the progressive color layer are respectively protected by the first TPU film and the second TPU film to make its service life longer. In addition, the ink is printed on the second TPU film by printing, so that it will not In case of tearing. The present invention also discloses a scheme in which the gradient metallic TPU film prepared by the above-mentioned preparation method is applied to the shoe sole, which can make the shoe sole more visually impactful and at the same time make the product more durable.

Description

technical field [0001] The invention relates to a material preparation method, in particular to a preparation method and application of a gradient color metallic TPU film. Background technique [0002] TPU film is a film made by special processes such as calendering, casting, film blowing and coating on the basis of TPU pellets. [0003] TPU (thermoplastic polyurethane) is increasingly popular because of its superior performance and environmental protection concept. At present, wherever PVC is used, TPU can become a substitute for PVC. [0004] TPU not only has excellent high tension, high tensile strength, toughness and aging resistance, but also is a mature environmental protection material. It is widely used in sports shoes: trademark decoration on soles and uppers, air bags, air cushions, oil bags, etc. [0005] At present, in order to attract customers, manufacturers will print gradient colors on the TPU film through inkjet printing. The film produced by this method ...

AI Technical Summary

Problems solved by technology

[0005] At present, in order to attract customers, manufacturers will print gradient colors on the TPU film through inkjet printing. The film produced by this method will appear after the film is applied to the product and processed by blister or some specific process. Cracks, incoherent colors lead to poor visual effects

In addition, the manufacturer will directly spray paint on the TPU film by hand. In this method, the color layer is exposed on the surface of the TPU film. After being applied to the product, it is extremely easy to be scratched off over time, and the production efficiency is also low.
