Abstract

The invention is applicable to the technical field of anti-rust oil, and provides a long-acting anti-rust oil composition for bearing parts and a preparation method thereof. The anti-rust oil composition comprises base oil, aromatic hydrocarbon oil, benzotriazole, polyoxyethylene ether, sodium alkyl benzene sulfonate, a defoaming agent, a mildew preventive, a modified film-forming agent and a titanate coupling agent. According to the invention, the anti-rust oil composition disclosed by the invention has effective anti-rust performance on the bearing part, and can form a layer of protective film on the surface of the bearing part so as to protect the bearing part for a long time; and the acrylic resin film-forming agent is modified by the phenolic epoxy vinyl ester resin, so that the thermal stability and salt fog resistance of a protective film formed on the surface of the bearing part can be effectively improved so as to facilitate the storage of the bearing part.

Description

technical field [0001] The invention belongs to the technical field of antirust oil, and in particular relates to a long-acting antirust oil composition for bearing parts and a preparation method thereof. Background technique [0002] Anti-rust oil is an oil solvent with reddish-brown appearance and anti-rust function. It is composed of oil-soluble corrosion inhibitor, base oil and auxiliary additives. According to the performance and usage, the anti-rust oil can be divided into fingerprint removal type anti-rust oil, water-diluted anti-rust oil, solvent-diluted anti-rust oil, anti-rust and lubricating dual-purpose oil, sealed anti-rust oil, replacement type anti-rust oil, Thin layer oil, antirust grease and vapor phase antirust oil, etc. [0003] Corrosion is one of the main forms of damage to fasteners, and it will cause great losses to automobiles, motorcycles and various vehicles and machinery. According to statistics, the annual direct economic loss caused by metal c...
