Abstract
A bearing having a surface and a self-lubricating surface coating composition deposited on the surface, wherein the self-lubricating surface coating composition includes a curable acrylate composition having a metallic composition. The metallic composition having a metallic acrylate compound according to Formula I: and about 30 mass % to about 45 mass % PTFE fiber.
Claims28
A bearing comprising:
- a surface;
- and
- a self-lubricating surface coating composition deposited on said surface, said self-lubricating surface coating composition comprises a curable acrylate composition comprising a metallic composition, said metallic composition comprises a metallic acrylate compound according to Formula I:
- and
- about 30 mass % to about 45 mass % PTFE fiber.
A method of manufacturing a self-lubricating surface coating composition, said method comprising:
- forming a curable acrylate composition comprising a metallic composition, wherein said metallic composition comprises a metallic acrylate compound according to Formula I:
- and
- combining a lubricant filler and a thixotrope, including about 30 mass % to about 45 mass % PTFE fiber, with said curable acrylate composition to form a self-lubricating surface coating composition.
A self-lubricating surface coating composition comprising:
- a.) a curable acrylate composition comprising:
- a metallic composition, comprising a metallic acrylate compound according to Formula I:
- b. a lubricant filler selected from polytetrafluoroethylene, copper powder, molybdenum disulfide, boron nitride powder, graphite powder or combinations thereof;
- c. about 30 mass % to about 45 mass % PTFE fiber;
- d. a thixotrope selected from fumed silica, fine polytetrafluoroethylene powder or combinations thereof;
- and
- e. an initiator selected from benzoyl peroxide, cumene hydroperoxide, methyl ethyl ketone peroxide, or combinations thereof.
A self-lubricating coating composition comprising:
- a curable acrylate composition comprising:
- a metallic composition comprising zinc monomethacrylate, zinc dimethacrylate and zinc oxide;
- ethoxylated bisphenol A dimethacrylate;
- trifunctional acid ester;
- triethylene glycol dimethacrylate;
- and ethoxylated trimethylolpropane triacrylate;
- a lubricant filler selected from polytetrafluoroethylene, copper powder, molybdenum disulfide, boron nitride powder, graphite powder or combinations thereof;
- about 30 mass % to about 45 mass % PTFE fiber;
- a thixotrope selected from fumed silica, fine polytetrafluoroethylene powder or combinations thereof;
- and
- an initiator selected from benzoyl peroxide, cumene hydroperoxide, methyl ethyl ketone peroxide, or combinations thereof.
