Abstract

The invention discloses an environmental-friendly anti-rust metal cleaning agent, which is prepared from the following raw materials of modified quaternary ammonium salt surfactant, a nonionic surfactant, an anionic surfactant, sodium tungstate, zinc carbonate, acrylic acid-maleic anhydride copolymer sodium salt, sodium polyacrylate, sodium molybdate dihydrate, sodium tetraborate, D-limonene, Schiff base corrosion inhibitors, cosolvents, anti-foaming agents, ethanol and water, wherein the nonionic surfactant is a mixture of alkylphenol ethoxylates, coco fatty acid diethanol amide, sorbitan fatty acid ester and FMEE; the anionic surfactant is a mixture of sodium dodecyl benzene sulfonate and sodium lauryl alcohol polyoxyethylene ether sulfate. The environmental-friendly anti-rust metal cleaning agent provided by the invention has the advantages that the cleaning efficiency is high; the detergency power is strong; after the cleaning, no residue is left; the antirust performance is good;the environmental-friendly effect is achieved.

Description

technical field [0001] The invention relates to the technical field of metal cleaning agents, in particular to an environment-friendly anti-rust metal cleaning agent. Background technique [0002] Oily dirt, such as anti-rust oil, lubricating oil, fuel oil and diesel oil and vegetable grease, is easy to adhere to the metal surface during the process of processing, manufacturing and storage. It needs metal cleaning agent to clean. Commonly used metal cleaning agents are divided into three types: solvent type, semi-solvent type and water-based type. At present, there are many metal cleaning agents on the market, but most of them have disadvantages such as unenvironmental raw materials, residues after cleaning, and certain corrosion to metals, which limit their application. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes an environment-friendly anti-rust metal cleaning agent, which has high clean...
