Preparation method of wire drawing decorative film

Abstract

The invention relates to a preparation method of wire drawing decorative film, the decorative film is composed of a substrate, a multi-functional layer, a decorative layer and a sticking layer which are sequentially overlapped, surface wire drawing is carried out to the substrate to form a wire-drawing linear surface, the wire drawing procedure is carried out on a surface wire drawing machine, a roll pair is arranged on the surface wire drawing machine, the substrate penetrates through the roll pair, and the roll pair is composed of an upper roll and a lower roll, raised lines are arranged onthe surface of the lower roll, the linear velocity difference between the upper roll and the lower roll is 50-150m / min, the upper roll and the lower roll are drive rolls, and the speed of the upper and the speed of the substrate are simultaneous. In the preparation method, the obtained wire drawing decorative film has good performance and low cost, is suitable for the processing technology of surface decoration of various plastic pieces and can be widely applied to the decoration of the plastic pieces such as home appliances, mobile phones and automobiles and the like.

Description

technical field [0001] The invention relates to a decorative film, in particular to a decorative film with a drawing effect. Background technique [0002] With the development of society, a large number of plastic parts are used in household appliances, automobiles, mobile phones and other components, and the requirements for surface decoration are getting higher and higher. At present, the surface metallization decoration of plastic parts adopts electroplating, vacuum deposition process or thermal transfer foil. The production environment of the electroplating process is poor, which is not good for the health of workers, and has high requirements for plastic parts, so it is no longer used in many fields. The vacuum deposition process has developed rapidly in the field of thin films in recent years, but the processing costs for molded plastic parts are relatively high. The transfer film is a dry process, which can achieve a variety of decorative effects and is conducive to...

AI Technical Summary

Problems solved by technology

The structure of the decorative film using this process is relatively complex, and the transfer coating generally has more than four layers. The structural layer includes: carrier base, release layer, protective layer, decorative layer and adhesive layer. There is also a support layer or an adhesion promotion layer between the layers. These products have more complex structures, high production costs, and complicated manufacturing processes.

[0003] The Chinese patent application number 200810079885.3 discloses a decorative film, which includes a base material, a decorative layer, an adhesive layer and a multifunctional layer, but the product does not have a drawing effect
