Problems solved by technology

When chromic acid is brought into the degumming solution, the surface of the workpiece is prone to incomplete metallization, that is, "plastic leakage" phenomenon, resulting in defective products, especially in large-scale automatic production, which often easily leads to great economic losses.

Abstract

The invention relates to peptization solution for the metalizing modification of a plastic surface. The peptization solution comprises a certain amount of acid or alkali and a certain amount of reducing agent; the usage amount of the acid or alkli in the chemical nickel deposition solution is 5-200g / l, and the usage amount of the reducing agent in the chemical nickel deposition solution is 1-100g / l. Through the strong reducing agent in the peptization solution, chromic acid carrying in the peptization solution can be reduced in time, thus the influence of chromic acid on palladium is avoided, the plastic metalizing production technology is more stable, and the service life of the peptization solution to be longer; the peptization solution has the characteristics of good stability, strong chromic acid resistance capability, long service life and the like.

Description

technical field [0001] The invention relates to a degumming solution, in particular to a degumming solution for plastic surface metallization modification. Background technique [0002] After the plastic surface is modified by metallization, it has metallic characteristics, which can be used for subsequent electroplating processing or chemical plating, and realizes the leap from non-metallic to metallic characteristics on the plastic surface, which has great application value. [0003] The commonly used methods for metallization modification of plastic surface are: chemical treatment, vacuum plating, spray plating, and doping metal powder or metal salt in the material. The metal film coating obtained by vacuum plating and spray plating is extremely thin, with poor conductivity, shielding performance and wear resistance; the method of doping metal powder or metal salt in polymer materials is cumbersome to operate, high in cost, poor in decorative performance, and rarely used ...
