Physicochemical and Tribological Properties of Anti-Seize Thread Lubricant

摘要

The di-aromatics base oil and graphite powder,blended with the viscosity index improver,and the anti-oxidant and rheological additive,were used to prepare a kind of anti-seize thread lubricant.Its physical chemistry properties,such as water resistance,thermal oxidation and aging properties,and tribological performance,were evaluated and compared with those of some commercial products.The results show that the overall performance of the anti-seize thread lubricant could meet the level of some commercial products,while its some properties such as thermal stability,anti-wear and anti-friction properties were better.The said anti-seize thread lubricant is more suitable for use under high temperature conditions.
