GREASE LUBRICANT COMPOSITION AND METHOD FOR PRODUCING THE SAME

摘要

The invention is related to grease lubricants, in particular, to compositions where either light low-temperature mineral oils such as transformer or instrument oils, or synthetic oils such as polyalphaolefin or alkylaromatic are used as a disperse medium. The object of the invention is provision of a stable grease lubricant with ultra-low temperature properties, scoring resistant properties and colloid stability. The essence of the invention is that addition of non-hydrated polyalphaolefin fraction C-Cwith a chilling point down to -60°C as a sulphurised agent allows to obtain a highly efficient grease lubricant with an ultra-low temperature range (-70°C), improved scoring resistant properties and high colloid stability.
