Problems solved by technology

However, the development of scratch-resistant brushed-metal imitation composite decorative film involves many technical bottlenecks, such as the difficulty in the simulation design of the brushed-metal pattern, the low adhesion fastness of the brushed-metal pattern layer formed by ink printing to the BOPET film layer, and the low adhesion to the composite adhesive. Layer interface bonding strength is low

Abstract

The invention provides a scratch resistant brushed metal imitating composite decorative film. A BOPET film subjected to painting and hardening treatment and a PVC film layer are bonded together through a composite adhesive layer. The lower surface of the BOPET film is provided with a primer layer, and the primer layer surface is printed with a brushed metal imitating pattern layer. The upper surface of the BOPET film is provided with an adhesion reinforced resin coating, the surface of which is provided with a scratch resistant hardened coating. The scratch resistant brushed metal imitating composite decorative film provided by the invention can be compounded to the surfaces of color steel plates and a variety of decorative materials to reach the decorative effect of brushed metal, and has the advantages of strong metal texture, soft luster, and beautiful and novel appearance.

Description

technical field [0001] The invention relates to a composite decorative film, in particular to a scratch-resistant metal-like brushed composite decorative film. Background technique [0002] As a new type of surface decorative film, the imitation metal wire drawing composite decorative film is favored by consumers for its novel pattern and strong metal texture, especially the color steel plate coated with imitation metal wire drawing composite decorative film, which has good bending resistance High performance, good surface decoration effect, scratch resistance, corrosion resistance and other excellent performances, the finished product brings a new visual aesthetic feeling to people and improves the product grade. [0003] At present, stainless steel brushed color plates used for home appliance panels and various decorative materials are expensive, difficult to produce and process, complicated in process, low in production efficiency, low in output, and single in color, thus...
