Environment-friendly anti-rust oil for bearing

Abstract

The invention discloses environment-friendly anti-rust oil for a bearing. The environment-friendly anti-rust oil comprises 70-88% of base oil, 5-10% of film-forming agent, 2-5% of anti-rust agent, 2-5% of calcium dinonyl naphthalenesulfonate, 1-3% of high-base-number petroleum calcium sulfonate, 2-5% of dodecyl succinic anhydride and derivatives thereof, 0-1% of antioxidant and 0-1% of organic alcohol ether. The environment-friendly anti-rust oil has the advantages that the anti-rust oil is ultrahigh in rust resistance, dampness and heat resistance and salt fog corrosion resistance, good in human sweat replacement performance, environmentally friendly, safe, free of toxic and harmful substances and capable of passing ROHS certification; film-forming coating of the anti-rust oil is ultrathin, attractive, easy to clean and the like.

Description

technical field [0001] The invention relates to an environment-friendly antirust oil for bearings. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body. When other parts move relative to each other on the shaft, the bearing can reduce the friction coefficient during its movement and ensure its rotation accuracy and keep the center position of the shaft fixed. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. After the bearings are cleaned during the manufacturing process, antirust treatment is required to achieve waterproof, moisture-proof, dust-proof, impact-proof, maintain the quality and precision of the bearings, and facilitate use and sales. Rust on bearings will affect its accuracy level, shorten its service life, and even cause it to be scrapped, or cause produc...
