Embodiment 1

[0025] Metal appearance elastic automotive trim, which is composed of:

[0026] Decorative base body molded from soft plastic;

[0027] It consists of 10% urethane modified epoxy acrylate resin, 8% polyurethane acrylic resin, 15% dipropylene glycol diacrylate resin, 3% 1-hydroxy-cyclohexyl-phenyl ketone, 0.5% defoaming aid, The rest are the primer film layer made of ethyl acetate paint on the substrate;

[0028] A PVD film layer made of metal indium on the primer film layer;

[0029] Made of 15% urethane acrylic resin, 5% urethane acrylic resin with 2 carbon-carbon double bonds (C=C), 4% pentaerythritol triacrylic resin (PET3A), 3% 1-hydroxy-cyclohexyl-phenyl ketone , 1% defoaming aid, the rest are toluene paint to make the topcoat film layer on the PVD film layer.

[0030] The preparation method of the decorative piece is as follows:

[0031] 1. Inject the TPEE raw material into the injection molding machine, and use the heat setting method to process to form the original...

Abstract

The invention discloses a metal-appearance elastic automotive decorative part, which uses soft rubber plastics to make a plastic substrate, and coats a composite layer of primer film layer-PVD film layer-top paint film layer on the surface of the substrate, and uses a special primer, surface paint Paint and other methods, so that the elastic automotive decorative parts can not only ensure the appearance of the metal, but also overcome the shortcomings of the poor bonding force between the soft plastic and the composite layer, so that the composite layer has stability, wear resistance, scratch resistance, A range of features, such as corrosion resistance, meet the standards set by major automakers.

Description

technical field [0001] The present invention relates to the technical field of plastic surface treatment, in particular to a surface treatment technology of automobile decorative parts. Background technique [0002] In order to achieve the effect of metal appearance, the existing automobile decorative parts mostly use hard plastic as the base material for surface treatment. As the automotive consumer market pays more and more attention to safety performance, the problem of sputtering damage caused by cracking and splashing of auto parts using hard rubber materials as the base material due to damage in a safety accident has received increasing attention, becoming one of the ways for car manufacturers to improve safety performance. research direction. [0003] Compared with hard plastics, soft plastics have the advantages of a wide range of elasticity, outstanding shock absorption, excellent cold resistance, and rich processing methods. Therefore, many automobile manufacturer...
