Problems solved by technology

However, in actual use, water-based metal cleaning agents are difficult to remove heavy oil stains on metal surfaces, and due to the presence of environmental media such as water, dissolved oxygen, and chloride ions, the corrosion of metal cleaning is more serious
The existing water-based metal cleaners have low cleaning rate and poor corrosion inhibition when used for steel cleaning, which limits their application

Abstract

The invention discloses a water-based cleaning agent special for steel. The water-based cleaning agent comprises a composite surface active agent, hydroxypropyl chitosan, amino acid, 2-ethylhexyl sulfate sodium, a compound containing an s-triazine structure, a plant extract, P-mercapto phenylboric acid, sodium metasilicate, sodium gluconate, molybdate intercalated zinc-aluminum-cerium hydrotalcite, furfuryl glycidyl ether, thiourea, polyorganosiloxane and water. The composite surface active agent is the mixture of lauryl sodium sulfate, hexadecylPyridinium chloride, polyethylene glycol octylphenol ether, sodium dodecyl sulfate and disodium lauroamphodiacetate. The water-based cleaning agent special for steel is high in cleaning efficiency, excellent in corrosion inhibition performance andcapable of meeting the steel cleaning requirement.

Description

technical field [0001] The invention relates to the technical field of metal cleaning agents, in particular to a special water-based metal cleaning agent for steel. Background technique [0002] Water-based metal cleaners are mainly composed of surfactants and corrosion inhibitors, which have the advantages of non-toxic, tasteless, safe and environmentally friendly, and low cost. The market share has been increasing in recent years. However, in actual use, water-based metal cleaning agents are difficult to remove heavy oil stains on metal surfaces, and due to the presence of environmental media such as water, dissolved oxygen, and chloride ions, the corrosion of metal cleaning is more serious. When the existing water-based metal cleaning agent is used for steel cleaning, the cleaning rate is low and the corrosion inhibition is not very good, which limits its application. Contents of the invention [0003] Based on the technical problems in the background technology, the p...
