Abstract

A photocurable resin composition for a self-lubricating liner contains a (meth)acrylate compound having an isocyanuric acid ring, a polytetrafluoroethylene resin and at least one of zirconium phosphate tungstate and zirconium phosphate.

Claims (18)

1. A photocurable resin composition for a self-lubricating liner, comprising:

a base resin containing a (meth)acrylate compound having an isocyanuric acid ring;

a polytetrafluoroethylene resin as a solid lubricant; and

a particle of at least one of zirconium phosphate tungstate and zirconium phosphate, wherein the polytetrafluoroethylene resin and the particle of at least one of zirconium phosphate tungstate and zirconium phosphate are contained in the base resin.

2. The photocurable resin composition according to claim 1 , wherein the photocurable resin composition further contains a thiol compound.

3. A sliding member having a sliding surface including a self-lubricating liner provided on the sliding surface, the self-lubricating liner formed of a cured product of the photocurable resin composition according to claim 2 .

4. The sliding member according to claim 3 , wherein the sliding member is a spherical bearing.

5. A sliding member having a sliding surface including a self-lubricating liner provided on the sliding surface, the self-lubricating liner formed of a cured product of the photocurable resin composition according to claim 1 .

6. The sliding member according to claim 5 , wherein the sliding member is a spherical bearing.

7. A photocurable resin composition for a self-lubricating liner, comprising:

a base resin containing a (meth)acrylate compound having an isocyanuric acid ring;

a powder, a particle or a fiber of polytetrafluoroethylene resin as a solid lubricant; and

a particle of at least any one of zirconium phosphate tungstate and zirconium phosphate, wherein the polytetrafluoroethylene resin and the particle of at least one of zirconium phosphate tungstate and zirconium phosphate are contained in the base resin.

8. A sliding member having a sliding surface including a self-lubricating liner provided on the sliding surface, the self-lubricating liner formed of a cured product of the photocurable resin composition according to claim 7 .

9. The sliding member according to claim 8 , wherein the sliding member is a spherical sliding bearing.

10. The photocurable resin composition according to claim 7 , wherein the photocurable resin composition further contains a thiol compound.

11. A sliding member having a sliding surface including a self-lubricating liner provided on the sliding surface, the self-lubricating liner formed of a cured product of the photocurable resin composition according to claim 10 .

12. The sliding member according to claim 11 , wherein the sliding member is a spherical bearing.
