Description

Technical field

[0001] The invention belongs to the technical field of plastic modification, and specifically relates to a metal-like ABS modified material and a preparation method thereof. Background technique

[0002] Plastic coloring can give plastic parts color and good appearance, which is an essential part of the plastic processing industry. Compared with metal parts, plastic parts have the advantages of low density, high cost performance and corrosion resistance.

[0003] In order to improve the decorative effect of plastic parts, the prior art usually adopts electroplating or spraying metal colors on the plastic surface. The electroplating process of plastic surface is long and requires multiple links such as surface cleaning, roughening, electroless plating, electroplating, and water washing. During the production process, more wastewater and liquid waste will be generated, which will cause serious environmental pollution. Surface spraying technology also requires cleani...
