Abstract

The invention discloses an environment-friendly water-based metal heavy oil stain cleaning agent, which comprises: 5-30 parts of alcohol amine ether, 1-8 parts of acetic acid, 0.5-7 parts of chelating agent, and 0.1-3 parts of bactericidal antiseptic , 5-20 parts of tartaric acid, 5-15 parts of fatty acid methyl ester ethoxylate sulfonate, 10-30 parts of nonionic surfactant mixture, and 0.5-5 parts of dispersion stabilizer. The alcohol amine ether of the present invention has various properties such as cleaning, rust prevention and lubrication, and can effectively improve the cleaning effect of the cleaning agent. This kind of cleaning agent can effectively remove oil stains caused by heavy oil, and the oil removal rate can reach more than 98%. The invention does not contain phosphorus substances, and the surface activity can be biodegraded or self-degraded, and will not pollute the environment. The cleaning agent prepared by the invention has obvious effect, high cleaning efficiency, and can effectively prevent metal corrosion.

Description

technical field [0001] The invention relates to an environment-friendly water-based metal heavy oil stain cleaning agent, which belongs to the technical field of metal cleaning agents. Background technique [0002] In modern production and life, metals are widely used in various important sectors such as construction, machinery, metallurgy, electronics, packaging, automobiles and high technology. They are not only functional materials but also structural materials, penetrating into various fields. [0003] In industrial production, even if metal parts do not undergo post-processing such as plating and other surface treatments, oil stains must be removed at a certain stage of production. After a certain period of operation in oil and gas transportation pipelines, fuel nozzles, and oil refining units, a certain amount of residual oil and dirt will often accumulate. It is easy to cause equipment accidents and safety accidents, which will bury hidden dangers for production and ...
