PACK OF ADDITIVES TO MOTOR OILS AND OIL CONTAINING THEREOF Russian patent published in 2015 - IPC C10M159/18 C10M169/06 C10N30/08 C10N40/25 

FIELD: chemistry.

SUBSTANCE: invention relates to a pack of additives to motor oils, which contains washing additives, an ashless nitrogen-containing dispersant, a block-copolymer of ethylene and propylene oxides, based on ethylenediamine, an antioxidative and anti-wear additive, phenyl-α-naphthylamine and octylated diphenylamine. As the washing additives the pack contains a solution in oil of a mixture of a carbonated product of dialkylbenzenesulphonic acid and calcium hydrate interaction, which has an alkaline number not less than 350 mg KOH/g, with calcium salt of an alkylphenol derivative with an alkaline number not less than 140 mg KOH/g, taken in a ratio of (1.5-2.5):1 by a weight part to the carbonated product, as the antioxidant and anti-wear additive used is zinc dialkyldithiophosphate counted per the content of phosphorus in final oil of 0.05-0.12 wt % and additionally contains either a product of condensation of benzotriazole, formaldehyde and amine or a derivative of tolutriazole with the following component ratio, wt %: the solution in oil of the mixture of the carbonated product of dialkylbenzenesulphonic acid with calcium hydrate interaction, which has the alkaline number not less 350 mg KHO/g, with calcium salt of the alkylphenol derivative with the alkaline number not less than 140 mg KOH/g, taken in the ratio of (1.5-2.5):1 by the weight part to the carbonated product - 30.00-38.00, ashless nitrogen-containing dispersant - 18.00-22.00, block-copolymer of ethylene and propylene oxides, based on ethylendiamine - 0.18-0.22, zinc dialkyldithiophosphate, counted per the content of phosphorus in final oil of 0.05-0.12 wt % - 10.00-22.00, phenyl-α-naphthylamine - 2.70-3.30, octylated diphenylamine - 9.00-11.00, product of condensation of benzotriazole, formaldehyde and amine or the derivative of tolutriazole - to 100. The claimed invention also relates to motor oil.

EFFECT: increase of the additives pack efficiency by an improvement of its antioxidant properties and creation of a possibility to deactivate constructive metals under conditions of high-temperature catalytic oil oxidation, which contains the pack, without the reduction of its anti-wear and anti-corrosion properties and increase of the engine resource.
