Engineering plastic surface metallization electroplating method

The invention relates to the technical field of engineering plastic surface treatment, and particularly discloses an engineering plastic surface metallization electroplating method which is low in processing cost and high in coating binding force. The engineering plastic surface metallization electroplating method comprises the following steps: carrying out alkaline washing on a plastic base material to remove oil stains on the surface of the plastic base material; sequentially carrying out acid etching and water washing on the plastic base material subjected to alkali washing to obtain a pretreated base material with specified surface roughness; drying the pretreated base material subjected to water washing and removing dust from the dried pretreated base material; carrying out surface modification on the pretreated base material subjected to dust removal to obtain a primary modified base material; plating a metallized coating on the surface of the surface-modified primary modified base material by adopting
