A conductive surface treatment method before electroplating of abs plastics

Abstract

The invention discloses a conductive surface treatment method before electroplating of ABS plastics, which uses the excellent conductivity and film-forming properties of graphene microchips to directly coat graphene coatings on the surface of plastic products by certain means to endow insulating ABS. Plastic surfaces have a certain conductivity. The ABS plastic coated with a graphene conductive layer on the surface prepared by the method of the present invention can be directly electroplated, which saves complex and cumbersome procedures such as roughening, sensitization, activation, and chemical plating in the traditional process, and is safer, more environmentally friendly, The method is simple and easy, and greatly shortens the technological process and cost, and is suitable for industrialized electroplating of ABS plastics of different shapes and sizes, and has important practical application value. The graphene conductive layer coated on the ABS plastic surface by the method of the invention is uniform and continuous, has good adhesion, and can be directly electroplated.

Description

A kind of conductive surface treatment method before electroplating of ABS plastic technical field The invention belongs to graphene technology and plastic surface treatment technical field, be specifically related to a kind of ABS plastic before electroplating The conductive surface treatment method. Background technique In recent years, with the advancement of science and technology and the continuous emergence of new materials, non-metallic materials such as plastics, glass, ceramics, gypsum, etc. Metal materials are more and more widely used in industry and daily life, and many products previously made of metal are now plasticized. These have greatly reduced the weight and cost of the product. But plastic also has certain disadvantages: non-conductive, It is not thermally conductive, not wear-resistant, easily deformed, not resistant to pollution, lacks metallic luster and aesthetics, which limits its use to a certain extent. range of use. If a layer of metal...

However, plastic also has certain disadvantages: non-conductive, non-thermal, non-wear-resistant, easy to deform, not resistant to pollution, lack of metallic luster and aesthetics, etc., which limits its scope of use to a certain extent

However, considering the dispersion of graphene materials in the resin matrix, this method is only applicable to graphene oxide and its derivatives as inorganic fillers, and its applicability is narrow.

Moreover, the conductivity of the plastic workpiece prepared by this method has not been significantly improved, only many micropores have been formed on the surface of the plastic workpiece, and the roughening step has been mainly omitted in the electroplating process. Fully utilized in the plastic plating process
