Abstract
Official abstract text for this publication.
The invention provides a grease composition for lubrication of a sliding surface made of resin, including a fluorine-based base oil and a synthetic hydrocarbon oil as a base oil; a fluorine-based thickener, and a lithium soap thickener or a lithium complex soap thickener as a thickener; and an extreme pressure additive as an additive. The invention also provides a sliding member including a sliding surface made of a resin wherein the grease composition for lubrication is applied to the sliding surface made of a resin.
First claim
Opening claim text (preview).
What is claimed is: 1. A grease composition for lubrication of a sliding surface made of a resin, comprising: a fluorine-based base oil; a synthetic hydrocarbon oil; a fluorine-based thickener; a lithium soap thickener; and an extreme pressure additive, wherein the synthetic hydrocarbon oil has a kinetic viscosity at 40° C. of 30 to 220 mm 2 /s, and the extreme pressure additive is at least one selected from the group consisting of tricresyl phosphate, triphenoxyphosphine sulfide and macromolecular ester, and the grease composition has a worked penetration in the range of 265 to 340. 2. A sliding member comprising a sliding surface made of a resin wherein the grease composition according to claim 1 is applied to the sliding surface. 3. The sliding member according to claim 2 , wherein the sliding member is a sliding switch, wherein the switch includes a waterproof film made of resin and a slider made of resin, the slider is configured to contact with the waterproof film while sliding and the grease composition is applied to at least one of the waterproof film and slider. 4. The sliding member according to claim 2 , wherein the sliding member is a gear device, including a first gear made of resin, wherein the grease composition is applied to the first gear. 5. A sliding member comprising a sliding surface made of a resin, wherein the sliding member is a sliding switch including a waterproof film made of resin and a slider made of resin, wherein the slider is configured to contact with the waterproof film while sliding and the grease composition is applied to at least one of the waterproof film and slider, wherein a grease composition is applied to the sliding surface, the grease composition comprising: a fluorine-based base oil; a synthetic hydrocarbon oil; a fluorine-based thickener; a lithium soap thickener; and an extreme pressure additive, wherein the synthetic hydrocarbon oil has a kinetic viscosity at 40° C. of 30 to 220 mm 2 /s, and the extreme pressure additive is at least one selected from the group consisting of tricresyl phosphate, triphenoxyphosphine sulfide and macromolecular ester.
