Copper-plated layer washing degreaser applied in electroplating industry

Abstract

The invention discloses a copper-plated layer washing degreaser applied in the electroplating industry. The copper-plated layer washing degreaser comprises the following ingredients in percentage by weight: 10-15 percent of sodium carbonate, 20-25 percent of sodium metasilicate, 20-25 percent of trisodium phosphate, 10-12 percent of anhydrous sodium sulfate, 5-8 percent of an anionic surfactant, 3-5 percent of a nonionic surfactant and 10-30 percent of a grinding material. A preparation method comprises the following steps: sieving the raw materials through a 20-mesh vibration sieve; respectively weighing the raw materials according to the percentage, and pouring the raw materials into a horizontal mixer for mixing; adding the anionic surfactant and the nonionic surfactant according to the percentage and mixing; adding the grinding material and mixing. The copper-plated layer washing degreaser disclosed by the invention can be used for rapidly removing the dirt such as grease, residual polishing paste, dust, fingerprints and the like from the surface of a copper layer before chroming and also has the function of roughening a copper-plated layer; an oxide layer on the surface of the copper layer is removed and the Ra value of the roughness of a copper polished layer is reduced to 0.10-0.12 micrometer from 0.06-0.08 micrometer, thus the binding force between the copper layer and a subsequent chromed layer is increased, the problems of partial corrosion of the chromed layer and the like are solved, reworking is reduced, the roller printing quality is improved and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of the electroplating industry, in particular to a copper plating layer cleaning and degreasing product used in the electroplating industry. Background technique [0002] In the gravure printing plate-making industry, the plate roller after copper plating has to undergo grinding, polishing, electric engraving and other processes before chrome plating. During these processes, the copper layer will be oxidized on the surface of the plate roller, and the residual polishing paste will be attached , mineral oil, dust, fingerprints and other pollutants, so it is necessary to thoroughly clean the plate roller before chrome plating to remove the above pollutants, improve the quality of the subsequent chrome plating layer, and reduce the amount of rework. The traditional cleaning method is to mix washing powder, detergent, inorganic salt filler, etc. in a certain proportion to form a paste and apply it on the surface...

AI Technical Summary

Problems solved by technology

The traditional cleaning method is to mix washing powder, detergent, inorganic salt filler, etc. in a certain proportion to form a paste and apply it on the surface of the plate roller to scrub with a sponge. This mixture needs to be prepared in advance, which is troublesome to use, and the cleaning effect is not ideal and time-consuming It is laborious and prone to quality problems such as poor bonding between the copper layer and the chrome-plated layer, local corrosion of the chrome-plated layer, and printing resistance of the plate roller.
