The invention discloses extreme pressure composite lubricating grease and belongs to the technical field of lubricating grease. The lubricating grease is prepared from, by part, 100-120 parts of base oil, 30-40 parts of thickening agents, 2-5 parts of waterproof agents, 10-20 parts of extreme pressure anti-wear reagents and 15-30 parts of peptizing agents through reaction; the base oil is composed of polyolefin and fluorocarbon oil, and the thickening agents are composite soap base thickening agents. According to the extreme pressure composite lubricating grease, due to the special combination of the thickening agents and the base oil, and the extreme pressure anti-wear reagents with borate and boric acid ester components, the extreme pressure resistance is greatly improved while the better physical performance of the lubricating grease is ensured; the waterproof property is achieved, corrosion to metal is avoided, and the lubricating grease is environmentally friendly and has good practicality.
