Abstract

The invention discloses a strong water-based metal surface oil contamination cleaning agent and a preparing method thereof, and relates to the technical field of metal surface treatment. The cleaning agent is composed of, by weight, 2-4 parts of polyoxyethylene cetyl ether, 0.5-1 part of modified sodium lignosulfonate, 2-4 parts of sodium citrate, 1-4 parts of EDTA tetrasodium, 3-6 parts of sodium metasilicate, 4-7 parts of carboxymethyl cellulose, 3-6 parts of ethylene glycol, 1-3 parts of sodium hydroxide and 40-50 parts of deionized water. The cleaning agent is fewer in foam, high in dispersion force and high in cleaning and oil contamination removing capacity, has a good dissolution effect on flora and fauna grease and mineral grease, can effectively remove oil contamination on the metal surface, is low in cleaning temperature and easy to wash, enables the metal surface to be bright, cannot corrode metal, is safe and environment-friendly, and cannot harm the health of an operator.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to a powerful water-based metal surface oil stain cleaning agent and a preparation method thereof. Background technique [0002] During the production and processing of metal materials and processed parts, oil and other substances are easy to adhere to the surface and may be rusted. In order to meet the processing technology requirements of metal materials and processed parts, and ensure the quality, service life and performance reliability of metal products, it is necessary to degrease and descale the metal surface before and after metal processing, as well as before assembly or packaging of finished products. The more traditional way is to use diesel oil, kerosene or gasoline as cleaning fluid to clean metal materials and workpieces, which not only wastes energy, but also has potential unsafe factors and may cause fire. In recent years, metal cleaning agents have ...
