Abstract
The present invention relates to lubricant composition comprising: a corrosion inhibitor comprising A1 and A2: A1: 0.3-3 wt. % of one or more octadecylamine N—C10-20 alkanoyl sarcosinates, A2: 1-5 wt. % of one or more substances selected from lanolin magnesium soap, lanolin calcium soap, lanolin barium soap, lanolin lithium soap, barium petroleum sulfonate and sodium petroleum sulfonate, 0.2-2 wt. % of one or more surfactants selected from Span-80, AEO-9 and TX-4; 10-40 wt. % of a lubricant base, 0.2-2 wt. % of fullerene C60, 50-80 wt. % of a solvent selected from D80, D100 and D110, and optionally, a propellant gas; all wt. % percentages are based on the total weight of the lubricant composition.
