Problems solved by technology

However, the traditional coating process is used in the primer, intermediate coating and top coating, which is not environmentally friendly, and the bonding force between the obtained film layer and the non-conductive metal film layer is still not ideal

Embodiment Construction

[0012] The plastic part provided by the technical solution and the preparation method thereof will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0013] refer to figure 1 The plastic part 10 provided by the first embodiment includes a polymer substrate 11 and a metallic film 12 and a diamond-like carbon film 13 sequentially formed on the polymer substrate. The polymer substrate may be selected from polycarbonate (PC), polypropylene (PP), acrylonitrile-styrene-butadiene copolymer (ABS), polymethylmethacrylate (PMMA), PC+ABS mixture. The metal texture film 11 is selected from silicon nitride, silicon carbide, titanium carbide and mixtures thereof, and its thickness is 50 nm to 1000 nm. The diamond-like carbon film 13 is selected from a hydrogenated amorphous diamond-like carbon film or a nitrided amorphous diamond-like carbon film, and its thickness is 5 nm to 50 nm. The metal texture film 11 has metallic luster, and the d...

Abstract

The invention relates to a plastic member comprising a polymer substrate. A metal texture film and a diamond-like carbon film, the metal texture film is selected from silicon nitride, silicon carbide, titanium carbide and a mixture thereof; the diamond-like carbon film is selected from a hydrogenated amorphous diamond-like carbon film or a nitriding amorphous diamond-like carbon film, and the thickness of the class diamond carbon film is between 5 and 50 nanometers. Because the metal texture film and the diamond-like carbon film both are not conducted, wireless transmission is not influenced when the plastic member is used as a shell of an electronic product having a wireless communication function, and the plastic member has the luster of the metal so that people has richer choices on the appearance of the electronic product.

Description

technical field [0001] The invention relates to a plastic part, in particular to a plastic part with a metallic texture and a film layer that is non-conductive and allows electromagnetic waves to pass through and a preparation method thereof. Background technique [0002] At present, various plastics, such as polycarbonate and polymethyl methacrylate, have been widely used in various electronic products as materials for mechanical components. However, due to the single color tone of the plastic, it does not meet people's needs for the individualization of electronic products. Therefore, there is a method of forming a metal film layer on the surface of the plastic to make the plastic part have a metallic texture. Since metal is conductive, plastic parts also have electromagnetic shielding function, which is a great advantage where electromagnetic shielding function is required, but in electronic products with wireless communication functions such as notebook computers, mobil...
