Abstract

The invention relates to an environment-friendly anti-rust oil for easily degreasing bearings and a preparation method thereof, belonging to the technical field of anti-rust bearings. The environment-friendly anti-rust oil for easy degreasing bearings of the present invention comprises the following components in parts by weight: 80-90 parts of base oil, 4-8 parts of calcium dinonylnaphthalene sulfonate, 3-6 parts of calcium petroleum sulfonate, 1-10 parts of disk, 1-20 parts of synthetic ester, 0.5-5 parts of tolyltriazole. The environment-friendly anti-rust oil for easily degreasing bearings of the present invention can meet the medium and short-term anti-rust requirements of bearing parts, has good degreasing performance, is easy to remove, and does not contain harmful substances such as aromatic hydrocarbons and heavy metals. It is safe to use, environmentally friendly, and has good storage stability.

Description

technical field [0001] The invention relates to an environment-friendly anti-rust oil for easily degreasing bearings and a preparation method thereof, belonging to the technical field of anti-rust bearings. Background technique [0002] After the bearing parts are coated, their antirust and self-lubricating functions can be improved. For bearing parts that have been coated with anti-rust oil before coating, the anti-rust oil should be easy to remove in the subsequent electroplating process, otherwise it may affect the quality of electroplating. A domestic scientific research unit found in the electroplating process of bearing parts that white spots appeared on the coating of the bearing ring, which seriously affected the quality of the coating. According to the unit, the turnaround period of bearing rings from sealing and packaging to electroplating is generally 6 to 12 months. Before coating, use gasoline, petroleum ether and other organic solvents to clean off the anti-ru...
