Technical Field

The invention relates to the technical field of anti-rust oil, and particularly relates to environment-friendly emulsified anti-rust oil.

Background

In order to reduce and avoid the loss caused by rust, the antirust oil is the most common protection method in the field of metal processing at present. On one hand, most of the antirust oil in the market uses oil-soluble barium salt as a high-efficiency antirust agent, and the antirust oil can be decomposed in natural environment to generate toxic water-soluble barium salt, which has serious harm to human health and environment; on the other hand, the use of volatile solvents as diluents generates a large amount of Volatile Organic Compounds (VOCs), pollutes the environment and is harmful to human health. Therefore, the emulsified anti-rust oil which uses water to replace a large amount of petroleum solvent has wide application prospect. However, emulsified rust preventive oils generally have a problem of insufficient rust preventive properties, particularly salt spray corrosion resistance.

Chinese patent CN 105112132A discloses an emulsified rust-preventive oil which is composed of petroleum sodium sulfonate, petroleum barium sulfonate, sodium dodecenylsuccinate, polymaleic anhydride, triethanolamine, benzotriazole, fatty alcohol polyoxyethylene ether carboxylic acid, isomeric fatty alcohol polyoxyethylene ether, diethylene glycol monobutyl ether, sorbitol monooleate, naphthenic base oil and water, and has excellent rust-preventive performance and emulsifying performance.

Therefore, an emulsified rust preventive oil with environmental protection and good salt spray corrosion resistance is needed.
