摘要
Using 12-hydroxystearate, nonan-edioic acid and lithium hydroxide as thickener, refined mineral oil and synthetic oil as base oil, along with some structure improver, antioxidant and anti-wear extreme pressure additive, lithium complex grease was developed. The dropping point of the grease is 331℃, friction factor is 0.0250.026 under 1.0kN, especially above 220℃, its friction factor is 2/3 of those of urea-based greases and other high temperature greases. At the same time, it has good waterproof, anti-oxidation effect and anti-corrosion properties. The results of the field experiment proves that its working temperature is higher than 600℃, and it has reasonable working life in 800℃.
