Resin composition for sliding member, and sliding member

A resin composition for a sliding member, the resin composition comprising:

• a plant-derived polyethylene resin as a matrix;
• and
• additives that are added to the plant-derived polyethylene resin, the additives comprising:
• a petroleum-derived polyethylene resin of 0.1 to 20% by mass;
• a modified polyolefin resin of 0.1 to 10% by mass;
• a lubricating oil of 0.5 to 5% by mass;
• and
• a plant-derived filler of 0.1 to 50% by mass,
• wherein the plant-derived polyethylene resin consists of a plant-derived high-density polyethylene resin,
• wherein the petroleum-derived polyethylene resin is selected from high-density polyethylene resin, ultra-high molecular weight polyethylene resin and acid-modified ultra-high molecular weight polyethylene resin,
• wherein the lubricating oil is selected from animal oil, vegetable oil, and ether-based synthetic oil,
• wherein the modified polyolefin resin is selected from polyolefin resin graft-modified with unsaturated carboxylic acid, anhydride thereof or derivative thereof, and polyolefin resin saponified obtained by saponifying polyolefin resin having an acetoxy group in a molecular chain with alkali, and
• wherein the plant-derived filler is selected from cellulose fiber, cellulose granules, and cellulose nanofiber.
