FIELD: chemistry.
SUBSTANCE: invention relates to an oil lubricant composition designed for use as a universal motor-gearbox oil for aircraft gearboxes. The lubricant composition contains the following in wt %: bis-[4-(1,1,3,3-tetramethylbutylphenyl]amine 1-3; (C7-C9) alkyl ethers of 3,5-bis-(1,1-dimethylethyl)-4-hydroxybenzopropanoic acid 0.3-3.0; 2- mercaptobenzothiazole 1-2; corrosion inhibitor 0.03-0.35; ester of pentaerythritol and C5-C10 fatty acids - the rest. The corrosion inhibitor contains a mixture of N,N-bis-(2ethylhexyl)-4-methyl-1H-benzotriazole-1-methylamine and N,N-bis(2ethylhexyl)-5-methyl-1H-benzotriazole-1-methylamine in ratio of 1:1.
EFFECT: lower evaporation potential at 175°C and improved lubrication properties.
