TRANSMISSION OIL Russian patent published in 2016 - IPC C10M111/02 C10M169/02 C10M119/16 C10N40/04 

FIELD: chemistry.

SUBSTANCE: invention relates to transmission oil, which as basic oil contains mixture of dibasic acid ester Syntolux L with viscosity from 2.0 to 6.0 mm²/s at 100°C and mineral oil with viscosity from 2.0 to 10 mm²/s at 100°C, and, in addition, pack of additives additionally contains thickening additive Syntolux V, which represents vinylalkyl polymer with viscosity from 200 to 5000 mm²/s at 100°C and molecular weight from 3000 to 20000, with the following component ratio, wt %: phenyl-α-napthylamine 0.2-0.6; 4-methyl-2,6-di-tert-butylphenol 0.75-1.25; anglamol-99 7.0-9.0; liquid chlorinated paraffins CP-470 6.5-7.5; benzotriazole 0.1-0.2; antifoaming agent "PENTA-4604" 0.01-0.05; thickening additive Syntolux V 5-30; basic oil to 100, including: ester Syntolux L with viscosity from 2.0 to 6.0 mm²/s at 100°C 5-50; mineral oil with viscosity from 2.0 to 10 mm²/s at 100°C 50-95.

EFFECT: increase of corrosion resistance, improvement of low-temperature and tribological characteristics of transmission oil.
