Abstract: KGW polyether industrial gear oil with additives such as anti-wear agent, antioxidant and anti-rust agent based on polyether was synthesized. The synthesized gear oil had excellent viscosity-temperature property, low temperature performance, excellent extreme pressure and anti-wear performance and very low friction coefficient, which can meet the lubrication requirements of various gear transmission devices under harsh conditions such as high load and strong impact. This series of products has reached the same quality level of the abroad products.

Key words: polymerization, friction coefficient, anti-wear, anti-rust, antioxidant
