Problems solved by technology

It has the following disadvantages: (1) It consumes a lot of water and energy, and produces a lot of waste water
(3) Emission of toxic waste gas
(4) Large amount of metal consumption
(6) High requirements on the surface of the substrate, narrow application
This invention is wire drawing on the metal substrate, which requires a certain metal film thickness. For this reason, acid copper plating is required before wire drawing, and the invention requires two degreasing treatments (blank degreasing treatment, acid copper wire drawing and then degreasing treatment) ), which requires a second transfer, the process is complicated and the cost is high

Abstract

A method for directly plating plastic with drawn wire appearance relates to a plastic plating process. The provided method for directly plating plastic with drawn wire appearance can realize drawn wire appearance for various plastic substrates. The method includes the following steps: (1) manual drawing is carried out on a plastic substrate; (2) the oil of the plastic substrate treated in step (1) is manually wiped off; (3) a metal film is coated on the workpiece treated in step (2) by physical vapor deposition; (4) a nickel layer is plated on the workpiece treated in step (3); and (5) after the workpiece treated in step (4) is washed with water and dried, a pigment film is coated on the workpiece by physical vapor deposition, and therefore a plastic workpiece with drawn wire appearance is obtained. Nickel can be directly plated on various drawn wire plastic substrates after films are coated, processes, such as roughening, sensitization and activation, are not needed, drawn wire appearance can be obtained, and has high metal texture.

Description

technical field [0001] The invention relates to a plastic electroplating process, in particular to a plastic direct electroplating method with a metal wire drawing appearance. Background technique [0002] At present, the surface of plastic parts obtains the appearance of metal wire drawing, which mainly adopts the wire drawing process after water electroplating. [0003] The conventional process of water electroplating is as follows: degreasing and dewaxing, roughening, activation, sensitization, reduction, electroless nickel, electroplating coke copper, electroplating acid copper, electroplating nickel, then wire drawing, degreasing, activation, electroplating chrome or finally physical vapor deposition. It has the following disadvantages: (1) It consumes a lot of water and energy, and produces a lot of waste water. (2) Use harmful chemical plating solutions and additives. (3) Emission of toxic waste gas. (4) A large amount of metal is consumed. (5) Use of hexavalent ...
