A kind of pre-plating treatment method of plastic parts for electroplating

Abstract

The invention relates to an electroplating pretreatment method for plastic parts for electroplating, and belongs to the technical field of plastic material treatment. The method comprises the steps that a plastic part for electroplating is fixed to a receiving pole of an electrostatic spinning device, and a polymer solution or melt forms nano-scale fiber through the electrostatic spinning device to be deposited on the surface of the plastic product, so that an electrospun film layer with a large number of submicron-order holes is formed on the surface of the plastic part. Compared with the prior art, the proper surface hole structure is given to the plastic part to be plated through the electrostatic spinning technology, so that the plastic part treated through the method can obtain the surface appearance where metal can be deposited without roughening, and can be put on a line for directly conducting sensitization, activation and electroplating.

Description

technical field [0001] The invention relates to a method for processing plastic materials, in particular to a method for pre-plating plastic parts used for electroplating. Background technique [0002] As a common material processing technology, plastic electroplating has been widely used in various fields of life and industry. For example, the showers we use every day, many automobile parts, interior decoration parts, etc., are all made of plastic electroplating. [0003] In fact, plastic does not conduct electricity, and it cannot be electroplated by itself. However, the predecessors used chemical deposition to bring a thin layer of metal on the plastic surface, thereby realizing the metallization of the plastic surface, endowing it with electrical conductivity, and enabling it to be electroplated. [0004] Generally speaking, the first step in plastic plating is to select suitable materials and create a large number of holes on the surface of the materials, which can en...

Problems solved by technology

This patent forms a microscopically rough surface by sandblasting on the surface of the plastic substrate, replaces dry sandblasting with wet sandblasting, and adds an appropriate amount of degreasing agent to the water, so that the surface of the substrate is sandblasted during the roughening process. Removal of grease on the surface of the substrate, the treatment method of the invention is actually a method of surface roughening, and requires the use of degreasing agents, etc., there are conventional problems in the above roughening methods
