COMPOSITION FOR PROTECTING MATED SURFACES AGAINST SETTING CAUSED BY CORROSIVE AND THERMOOXIDATIVE EFFECTS Russian patent published in 1997 - IPC

FIELD: mechanical engineering; compositions (lubricants) intended to protect mated surfaces, predominantly in motor-cars, against setting induced by atmospheric corrosion or by heat effects. SUBSTANCE: traditionally proposed composition comprises molybdenum disulphide, titanium dioxide, aluminium, petrolatum and mineral oil. Inventive novelty of composition resides in fact that, in addition to above-enumerated components, it comprises two organic compounds 2-bis(gamma-dimethylaminopropyl)aminomethyl-4-isoalkylphenols, namely, 2-bis(gamma-dimethylaminopropyl)aminomethyl-4-isononylphenol and 2-bis(gamma-dimethylaminopropyl)aminomethyl-4-isododecylphenol, and also in fact that said components are taken in following weight ratio, wt.%: molybdenum disulphide (72-75), titanium dioxide (2.5-3), aluminium (3.5-4), petrolatum (12-13), 2-bis(gamma-dimethylaminopropyl)aminomethyl-4-isoalkylphenols (3-4), mineral oil being balance. EFFECT: composition offers higher efficiency of corrosion protection. 5 tbl
