▎ 摘　　要

NOVELTY - Robot oil comprises base oil and additives. The added amount of additive is 5.8-8.3 wt.% of base oil. The base oil is composed of 80-88 wt.% polyether, 10-15 wt.% high viscosity polyester and 2-5 wt.% polyisobutylene. The additive is made of 2-3 wt.% oil agent, 2-4 wt.% amino thioester, 0.001-0.005 wt.% oil-soluble graphene, 0.3-1 wt.% composite antioxidants, 0.001-0.002 wt.% composite defoamer, 0.1-0.3 wt.% organic molybdenum, 0.1-0.5 wt.% ammonium phosphate mixture and 0.3-0.4 wt.% metal deactivator. USE - Robot oil. ADVANTAGE - The product is biodegradable, environment-friendly and low-cost and has excellent anti-friction performance, good low temperature performance, excellent oxidation resistance and temperature control performance and good rust resistance property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of robot oil comprising adding polyether, polyester and polyisobutylene into the reactor, heating at 60-70 degrees C, stirring for 8-10 minutes, mixing oil agent, aminothioester, complex antioxidant, heating oil agent, amino thioester, oil-soluble graphene, composite antioxidants, composite defoamer, organic molybdenum, ammonium phosphate mixture and metal deactivator at 60-70 degrees C for 30 minutes and filtering in 1 mu m filter bag.
