NOVELTY - An agent comprises 0.01 pt. wt. or less graphene, 1-3 pts. wt. 150N base oil, 0.05-2 pts. wt. long-chain primary alkyl zinc dithiophosphate, 0.1-0.5 pt. wt. primary alkyl zinc dithiophosphate, 0.5-1.5 pt. wt. dimer acid, 0.5-1.5 pt. wt. phosphate ester, 2-4 pts. wt. dialkenyl succinimide, 0.5-1 pt. wt. glycol oleate, 0.5-1.5 pt. wt. high-base synthetic calcium sulfonate, and 0.5-1 pt. wt. polyisobutylene. USE - Agent used as lubricant additive for improving sealing effect of rubber oil seal and packing. ADVANTAGE - The agent has excellent abrasion resistance, anti-friction performance, oxidation resistance, corrosion resistance, anti-wear energy-saving agent, noise reduction and anti-rust on metal surfaces. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the agent, which involves mixing long-chain primary alkyl zinc dithiophosphate, ethylene glycol oleate and 150N base oil, de-electrostatic-treating at 50-100 degrees C, preferably 40-60 degrees C for 10-30 minutes to obtain mixture (A), mixing dialkenyl succinimide with dimer acid, phosphate ester, primary alkyl dithiophosphate zinc and polyisobutylene at 50-90 degrees C for 10-30 minutes to obtain mixture (B), mixing mixture (A) and mixture (B), adding high-basic synthetic calcium sulfonate and graphene, heating to 80-90 degrees C, stirring, mixing for 10-30 minutes, cooling to 50 degrees C and discharging.
