Abstract

The invention discloses anti-rust oil for metal and a preparation method thereof. The anti-rust oil for the metal comprises, by weight, 3-6 parts of lauric monoethanolamide, 3-6 parts of sodium sulfate, 0.5-1 part of sodium alginate, 0.2-1 part of organic-siloxane, 2-6 parts of lauric acid, 1-4 parts of triethanolamine, 0.5-1 part of ethylene glycol oleate, 1-3 parts of silicon dioxidem 0.2-0.8 part of mono-glyceride and di-glyceride, 5-10 parts of phosphoric acid, 1-4 parts of aluminum oxide and 70-80 parts of water. According to the preparation method, the lauric acid and the phosphoric acid are added into a container to be heated to 65-70 DEG C, the aluminum oxide is added into the mixture, the silicon dioxide, the mono-glyceride and the di-glyceride are added after a stirring reaction, the mixture is stirred for 30-40 minutes and cooled to 50-60 DEG C, and the a first mixture is obtained; water is added into the other container, the remaining components are added into the container to be mixed uniformly, and the mixture is heated to 50-60 DEG C; the two kinds of mixtures are stirred, mixed and cooled to room temperature, so that the anti-rust oil for the metal is obtained.

Description

technical field [0001] The invention belongs to the technical field of preparation of metal surface treatment agents, and in particular relates to a metal antirust oil and a preparation method thereof. Background technique [0002] Rust prevention on metal surfaces is a common process during metal processing or use. Commonly used metal cleaning agents are divided into solvent-based, semi-solvent-based and water-based. Among solvent-based metal cleaners, petroleum solvents are flammable, explosive, and a waste of resources. Chlorofluorocarbons are the most commonly used solvent-based metal cleaners, but are banned due to their damage to the atmospheric ozone layer. Therefore, solvent-based metal cleaners are gradually being replaced by semi-solvent and water-based metal cleaners. Compared with the semi-solvent type, the application advantages of the water-based metal cleaning agent are more prominent. [0003] At present, medium-temperature or low-temperature anti-rust oil...
