Abstract

A plastic part comprises a plastic base and non-conducting coating film layer formed in the plastic base. The non-conducting coating film layer is a silicon-aluminum composite layer, and an L* coordinate, an a* coordinate and a b* coordinate of a chromaticity area of the silicon-aluminum composite layer in the CIE LAB color scale system respectively are 70-75, 0-0.5 and 0-0.5. The invention further provides a manufacturing method of the plastic part.

Description

technical field [0001] The invention relates to a plastic part and its manufacturing method. Background technique [0002] In the prior art, indium tin is usually used as the evaporation material, and a white, non-conductive indium tin film layer with good light transmittance and strong metallic texture is evaporated on plastic parts (such as mobile phone casings) by evaporation coating. . In this way, the plastic part has electromagnetic shielding performance and at the same time it can present a white and elegant appearance effect. However, in the process of evaporation coating with indium tin, the atmosphere in the vacuum chamber must be strictly controlled to prevent indium tin from being oxidized to indium tin oxide and make the formed film layer conductive, which increases the requirements for coating equipment. In addition, the price of indium is relatively high, which increases the preparation cost of the indium-tin non-conductive film layer. Contents of the inve...
