Abstract

The invention discloses metal rust-preventive oil containing polyisobutene acid glyceride. The metal rust-preventive oil is made of the following raw materials including, by weight, 110-120 parts of No.120 solvent oil, 1.8-3.3 parts of wool fat, 2.1-3.4 parts of the polyisobutene acid glyceride, 1-2 parts of silane coupling agents KH560, 0.3-0.4 part of aluminum stearate, 0.1-0.2 part of isobutanol, 0.2-0.3 part of an antioxidant 168, 0.1-0.2 part of an antioxidant 264, 0.1-0.2 part of polypropylene glycol diglycidyl ether, 0.1-0.2 part of naphthenic acid, 0.9-1.2 parts of benzotriazole, 0.7-1.2 parts of amino ethyl group heptadecenyl imidazoline, 0.5-1 part of hydrogenation tallow amine, 0.4-0.5 part of polyisobutenyl succinimide, 0.3-0.8 part of lauryl sodium sulfate, 5-7 parts of composite film-forming materials and 1-2 parts of modified nanometer water talcum powder. The metal rust-preventive oil has good contact rust-preventive performance and good gas-phase rust-preventive effects, and has good gas-phase rust-preventive effects and contact rust-preventive effects 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 polymethacrylate glyceride. 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 surface, and can...
