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 coating binding force of an engineering plastic and application thereof, and aims at overcoming the defects existing in the electroplating of existing engineering plastics, the plastic is subjected to treatment by a chemical surface treating agent of a specific formula in sequence according to a certain method, so that the plastic is modified, and the hydrophilicity and the coating binding force are improved; the surface treating agent used for enhancing the coating bonding force of the engineering plastic has the advantages that the preparation is simple and the industrial feasibility is high, the plastic subjected to modification treatment has greatly improved hydrophilicity and relatively good stability, the plating-absorption capability is greatly enhanced, the coating binding force is greatly improved, the service life is long, the defects of the traditional plastics are broken through, and the surface treating agent has very strong practical value.

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 engineering plastic coatings 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 unstable....
