Problems solved by technology

[0002] When the workpiece is electroplated and copper-plated, it is often due to various or artificial or process reasons that the copper plating will adhere to a large amount of oil, dust and other substances on the surface of the workpiece, and at the same time, the surface of the workpiece will also be oxidized to varying degrees, resulting in oxidation. Therefore, it is necessary to clean the workpiece after copper plating. When using traditional cleaning and degreasing agents, not only the cleaning effect is not good, but there are many residues.

Abstract

The invention discloses a cleaning degreaser for electroplating. The cleaning degreaser is characterized by consisting of the following raw material components in parts by weight: 5-8 parts of an anionic surfactant, 3-5 parts of a non-ionic surfactant, 8-10 parts of alkyl phenol polyoxyethylene ether, 15-20 parts of sodium carbonate, 17-23 parts of sodium metasilicate, 15-18 parts of a metal anti-rusting agent and 2-5 parts of a cleaning corrosion inhibitor. The cleaning degreaser disclosed by the invention, which is prepared from the raw materials, is not only convenient to use but also can be used for rapidly removing grease, polishing paste, fingerprint and like stains on the surface of a workpiece; and meanwhile, the cleaning degreaser can be used for removing an oxide layer on the surface of a copper layer and is quite excellent in cleaning effect; labor is saved and rework rate is reduced, and meanwhile, the quality and the service life of the product are improved.

Description

technical field [0001] The invention relates to the field of electroplating, in particular to a cleaning and degreasing agent for electroplating. Background technique [0002] When the workpiece is electroplated and copper-plated, it is often due to various or artificial or process reasons that the copper plating will adhere to a large amount of oil, dust and other substances on the surface of the workpiece, and at the same time, the surface of the workpiece will also be oxidized to varying degrees, resulting in oxidation. Therefore, it is necessary to clean the workpiece after copper plating. When using traditional cleaning and degreasing agents, not only the cleaning effect is not good, but there are many residues. Contents of the invention [0003] In view of the above problems, the invention provides a cleaning and degreasing agent for electroplating. [0004] For solving above technical problem, technical scheme provided by the invention is: [000...
