SOLID SELF-LUBRICATING MATERIAL Russian patent published in 1996 - IPC

FIELD: lubricating compositions. SUBSTANCE: material has the following ratio of components, wt.-%: butadiene acrylonitrile rubber 15-20; graphite 20-45; asbestos 20-40; barium sulfate 1-20; zinc oxide 0.5-2.0; sulfur 3.0-4.5, and technological additive 4.7-7.7. The latter involves vulcanization accelerating agent, plasticizer, activating agent and antioxidant. The new solid self-lubricating composition shows increased wear-resistance and thermal stability (by 100-150% as compared with known one). EFFECT: enhanced safety, improved properties of material. 2 tbl
