Problems solved by technology

This method is effective for metal, but it is not feasible for metal and plastic composite parts
Because the general protective ink has excellent adhesion to plastics, this will seriously affect the convenience and process of ink removal
In addition, alkaline ink remover will also have adverse effects on plastics such as erosion, biting, and discoloration.

Embodiment 1

[0029] The method for surface decoration processing of aluminum alloy and plastic composite parts of the present invention:

[0030] A. Dust removal, polishing and cleaning of aluminum alloy and plastic composite parts;

[0031] B. Use a compressed air spray gun to spray the photosensitive anti-sandblasting ink on the surface of the aluminum alloy and plastic composite in step A. The spraying viscosity of the photosensitive anti-sandblasting ink is 9-10 seconds. Filter it with 400 mesh gauze before spraying. The thickness of the sandblasting ink is 20±2μ; then put it in an oven and bake at 90°C for 30 minutes until the surface of the photosensitive anti-sandblasting ink is dry and does not stick to the film. After cooling, place a film with a decorative pattern on the photosensitive anti-sandblasting ink to carry out Exposure, wherein the exposure process uses a UV exposure machine for exposure, and the exposure energy is 400-600mj / cm 2 ; Then use a sodium carbonate solution ...

Abstract

The invention discloses a method for surface decoration of a metal and plastic composite piece. The method comprises the following steps of: pretreating the metal and plastic composite piece; spraying photoimageable sand blast-resist ink onto the surface of the metal and plastic composite piece by using a compressed air spray gun, drying until the surface of the photoimageable sand blast-resist ink is dry and cannot stick films, cooling, placing a film on which a decorative pattern is drawn on the photoimageable sand blast-resist ink and exposing, and developing; performing sand blast treatment on the developed surface of the metal and plastic composite piece by using a sand blasting machine to ensure that areas which are not protected by the ink become frosted surfaces; anodizing the metal and plastic composite piece; spraying computerized numerical control (CNC) ink on the metal and plastic composite piece, and drying by using an ultraviolet (UV) photocuring machine; performing CNC cutting on the metal and plastic composite piece, and edging and polishing positions where the CNC ink is not coated; and removing the photoimageable sand blast-resist ink and the CNC ink from the metal and plastic composite piece by using a neutral deinking agent.

Description

technical field [0001] The invention relates to a method for surface decoration and processing of metal and plastic composite parts, belonging to the field of material surface chemical treatment. Background technique [0002] Polishing, atomization, wire drawing and other processing on the metal surface is a popular decoration method in recent years. The general processing method is to spray or screen print a layer of protective ink on the metal material. Ink stripper removes protective ink. This method is effective for metal, but it is not feasible for metal and plastic composite parts. Because the general protective ink has excellent adhesion to plastics, this will seriously affect the convenience and process of ink removal. In addition, the alkaline ink remover will also have adverse effects on plastics such as erosion, biting, and discoloration. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art a...
