Embodiment 1

[0028] A plastic chrome-plated product, from the inside to the outside: ABS plastic workpiece 4, alicyclic epoxy modified acrylic resin coating 1, vacuum ion chrome plating layer 2, titanium oxide film coating 3; alicyclic epoxy The thickness of the modified acrylic resin coating 1 is 15 μm; the thickness of the vacuum ion chromium plating layer 2 is 3 μm; the thickness of the titanium oxide thin film coating is 4 μm. Cycloaliphatic epoxy-modified acrylate light-curing coating is formed by mixing and cross-linking cycloaliphatic epoxy resin and hydroxyacrylate. It is a photosensitive prepolymer with the performance characteristics of both cycloaliphatic epoxy and acrylate. At the same time it also contains photoinitiator, reactive diluent and other various additives.

[0029] The production method of above-mentioned product comprises the following steps successively:

[0030] 1. Pretreatment First, scrub with alcohol organic solvent to remove the oil stain and residual mold r...

Embodiment 2

[0041] A plastic chrome-plated product, from the inside to the outside: ABS plastic workpiece 4, alicyclic epoxy modified acrylic resin coating 1, vacuum ion chrome plating layer 2, titanium oxide film coating 3; alicyclic epoxy The thickness of the modified acrylic resin coating is 12 μm; the thickness of the vacuum ion chromium plating layer 2 is 2 μm; the thickness of the titanium oxide film layer 3 is 2 μm.

[0042] The manufacturing method of this embodiment is the same as that of Embodiment 1.

Abstract

The invention relates to a chromium-plated plastic product, belonging to the new material and surface technical field. The chromium-plated plastic product comprises the matrix material and chromium-plated layer and is characterized in that the chromium-plated plastic product also comprises organic coating layer and titanium oxide film layer; the matrix material, organic coating layer, chromium-plated layer and titanium oxide film layer are arranged from inside to outside; the thickness of the organic coating layer is 10-20mu m; the thickness of the chromium-plated layer is 2-3mu m; and the thickness of the titanium oxide film layer is 2-4mu m. The vacuum-deposited chromium plastic product of the invention which can replace the plastic electroplating product has three-layer structure, the modification of the structure leads the product to have the advantages of low cost, no toxicity and simple procedure and solve the technical problem that the prior art for preparing plastic chromium-electroplated product has severe pollution, complicated technology and high cost.

Description

technical field [0001] The invention relates to a plastic chrome-plated product, which belongs to the technical field of new materials and surfaces. Background technique [0002] Plastic electroplating products are a product obtained by metallization on a plastic substrate. It is composed of a plastic substrate, a thin metal layer deposited on its surface, and an electroplated chromium layer plated on the metal layer. The above products have the advantages of both plastic and metal. The electroplated chromium layer has a strong passivation performance in the atmosphere, has a beautiful silvery white luster, and can be maintained for a long time. It is resistant to alkali, nitric acid, sulfide, carbonate, organic It is stable in acid and other corrosive media; the electroplated chromium layer also has high hardness, good wear resistance and heat resistance. Therefore, plastic electroplating products are widely used in automobiles, motorcycles, household appliances, decoratio...
