Surface treating agent for enhancing binding force of engineering plastic coating and application

The invention discloses a surface treating agent for enhancing binding force of engineering plastic coating and application. According to the defects existing in the existing engineering plastic plating process, the plastic passes through chemical surface treating agents of a specific formula in sequence and is treated according to a certain method, the plastic is modified, and the hydrophilic performance and the binding force of the plastic and the plating layers are improved. The surface treating agent for enhancing the binding force of the engineering plastic and the plating layers is easy to prepare and high in industrial feasibility, the hydrophilic performance of the modified plastic is remarkably improved, good stability is achieved, the absorption and plating capacity is greatly improved, the binding force with the coating is greatly improved, and the service life is long. The defects of traditional plastic are overcome, and high practical value is achieved.
