Problems solved by technology

The decorative film obtained by this method mainly has the following problems: 1. The surface performance of the decorative film is limited, the hardness is low (generally less than HB), the solvent resistance and wear resistance are poor, and it cannot meet the needs of high-end decoration; 2. It cannot Meet the requirements of double-sided brushed decoration of transparent plastic parts, that is, when the decorative film obtained by this method is used on transparent plastic parts, the effect of brushed decoration on the front and back of transparent plastic parts is obviously different

Abstract

The invention relates to a double-faced drawing decorative film for a transparent plastic component, which comprises a supporting body, a stripping layer, a decorating layer and a sticking layer. The surface of the stripping layer is coated with the coating liquid of a protecting layer, the protecting layer is obtained by hot drying and solidifying treatment, surface drawing treatment and ultraviolet solidifying treatment, and then the surface of the protecting layer is evaporated with the decorating layer. The coating liquid of the protecting layer comprises the following components according to parts by weight: 30 to 50 parts of multi-functional acrylate resin containing hydroxy groups, 5 to 10 parts of isocyanate resin with double bonds, 10 to 20 parts of reactive diluent, 1 to 2 parts of photoinitiator, 1 to 2 parts of plasticizer, 0 to 5 parts of pigment and 30 to 60 parts of solvent. The decorative film disclosed by the invention has excellent solvent resistance and abrasion resistance, the drawing texture is true, the metal drawing effects of a hot stamping face and the back face of a plastic component to be stamped are consistent, and the requirement of decoration of a transparent plastic component can be met. The double-faced drawing decorative film for the transparent plastic component can be widely applied to the surface decoration of the transparent plastic component.

Description

technical field [0001] The invention relates to a metal decorative film, in particular to a double-sided brushed decorative film for transparent plastic parts. 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. The surface of the plastic parts is decorated with metal wire drawing, which can show a high-quality decorative effect and meet the needs of high-end decoration. [0003] Chinese patent application number 200910175221.1 discloses a method for preparing a brushed decorative film, which uses drawing on the surface of a substrate, and then decorates the plastic surface with a drawing effect through a hot stamping process. The decorative film obtained by this method mainly has the following problems: 1. The surface performance of the decorative film is limited, the hardness is low (generally less than HB), the solvent resistance and wear resistanc...
