NOVELTY - An antioxidant self-healing lubricant comprises 30-40 pts. wt. tetratitanic acid, 40-50 pts. wt. graphene oxide, 50-60 pts. wt. lubricant base oil, 10-15 pts. wt. p-hydroxybenzaldehyde, 3-7 pts. wt. sodium polyacrylate, 2-8 pts. wt. calcium sulfide alkylphenol, 1-6 pts. wt. polyvinyl alcohol, 4-11 pts. wt. sodium sulfate, 7-12 pts. wt. polycarboxylic acid water reducer, 8-15 pts. wt. sodium lignosulfonate, 15-20 pts. wt. nitrite, 20-25 pts. wt. zinc dialkyldithiophosphate, 1-7 pts. wt. polyisobutenyl succinimide, 10-15 pts. wt. polymethacrylate, 5-10 pts. wt. calcium chloride, 1-6 pts. wt. sodium acetate, 10-15 pts. wt. magnesium chloride, 20-25 pts. wt. acid phosphate amine salt, 5-10 pts. wt. alkylamine, 6-11 pts. wt. propylene glycol, 4-8 pts. wt. triethanolamine, 3-7 pts. wt. thiodipropionic acid, 2-6 pts. wt. tert-butylhydroquinone, and 5-15 pts. wt. dimer acid ethylene glycol monoester. USE - Antioxidant self-healing lubricant. ADVANTAGE - The antioxidant self-healing lubricant has excellent self-repairing anti-freezing effect and oxidation resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the antioxidant self-healing lubricant, which involves: (S1) mixing tetratitanic acid, graphene oxide, p-hydroxybenzylaldehyde, sodium polyacrylate, calcium sulfide alkylphenol and polyvinyl alcohol, and reacting to prepare a mixture (A); (S2) mixing sodium sulfate, polycarboxylic acid water reducer, sodium lignosulfonate, nitrite, zinc dialkyldithiophosphate, polyisobutenyl succinimide, polymethacrylate, calcium chloride and sodium acetate, and reacting to prepare a mixture (B); (S3) mixing magnesium chloride, acid phosphate amine salt, alkylamine, propylene glycol, triethanolamine, thiodipropionic acid, tert-butylhydroquinone and dimer acid ethylene glycol monoester, and reacting to prepare a mixture (C); and (S4) uniformly mixing the mixtures (A)-(C), then adding lubricating oil base oil, stirring and mixing.
