Problems solved by technology

However, the anti-rust effect of simple amines in mineral oil is not good enough, and amine salts or other compounds formed by amines and organic acids are commonly used, such as octadecylamine oleate, cyclohexylamine stearate, etc.

Abstract

The invention discloses metal rust-preventive oil comprising coconut oil fatty acid diethanolamide. The oil is prepared from the raw materials of: No.120 solvent oil, a silane coupling agent KH540, a silane coupling agent KH 602, microcrystalline wax, isobutyl methacrylate, modified nano-grade shale powder, an antioxidant 1010, a composite film-forming material, polyethylene glycol, isobutyl alcohol, an antioxidant 1076, coconut oil fatty acid diethanolamide, barium petroleum sulfonate, petroleum sulfonate, benzotriazole, 2-aminoethyl heptadecenyl imidazoline, magnesium naphthenate, nonylphenol polyoxyethylene ether, Span 80, an antioxidant T501, and phenylethanolamine A. The rust-preventive oil provided by the invention has excellent contact rust resistance and good gas-phase rust resistance. The rust-preventive oil provided by the invention provides good gas-phase rust resistance and contact rust resistance for steel and brass.

Description

technical field [0001] The invention relates to the field of metal surface treatment agents, in particular to a metal antirust oil containing coconut oil fatty acid diethanolamide. Background technique [0002] Metal surface treatment agent refers to the general term for various chemical agents for metal surface treatment. Metal surface treatment includes degreasing, rust removal, phosphating, antirust and other substrate pretreatments, which are prepared for metal coating technology and metal protection technology. The quality of substrate pretreatment has a great influence on subsequent coating preparation and metal use. big impact. [0003] Oil-soluble rust inhibitors are also called oil-soluble corrosion inhibitors. Most are long carbon chain organic compounds with polar groups. The polar groups in the molecule are tightly adsorbed on the metal surface by the action of charge; the non-polar group long carbon chain hydrocarbons are facing the outside of the metal surfa...
