Problems solved by technology

[0003] However, in actual work, the quality of plastic electroplating products is extremely unstable. On the one hand, it depends on the choice of electroplating materials, and on the other hand, it is also related to the suction and plating ability of the plastic itself. How to process engineering plastics Modification treatment to improve the absorption and plating ability of engineering plastics, its surface treatment agent is particularly important

Abstract

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.

Description

technical field [0001] The invention relates to the field of polymer modified plastics, in particular to a surface treatment agent for enhancing the binding force of coatings of engineering plastics and its application. Background technique [0002] With the rapid development of industry, the application of plastic electroplating is becoming more and more extensive, and it has become one of the important means of surface decoration in plastic products; compared with metal parts, plastic electroplating products can not only achieve a good metal texture, but also reduce the weight of the product , while effectively improving the appearance and decoration of plastics, it also improves its performance in terms of electricity, heat and corrosion resistance. Nowadays, in the application field of engineering plastics, plastic electroplating products have a wide range of applications. [0003] However, in actual work, the quality of plastic electroplating products is extremely unsta...
