MULTIPURPOSE PLASTIC GREASE FOR HEAVY LOADED FRICTION ASSEMBLIES Russian patent published in 2020 - IPC C10M169/06 C10M125/00 B82B3/00 B82Y40/00 C10N40/00 C10N30/06 

FIELD: chemistry.

SUBSTANCE: invention relates to a composition of multipurpose grease for heavy-duty friction assemblies, which can be used in mechanisms for various purposes of mobile equipment and stationary equipment. Multi-purpose grease contains, wt%: thickener – 4.0–25.0; nanostructured functional additive – nano-sized borate and / or calcium carbonate particles – 0.5–5.0; antioxidant – 0.2–0.5; corrosion inhibitor – 0.0–2.0; additive with anti-wear and/or anti-scoring properties – 0.0–3.0; solid filler – 0.0–20.0; base oil – up to 100.

EFFECT: technical result consists in reduction of wear and prevention of scoring due to formation in boundary layer of strong chemisorption film, protecting friction surface, and modification of thickener fibers with nanoparticles of borate and / or calcium carbonate during formation of structural framework of grease.
