Изобретение относитс к составам смазочных масел, обладающих повышенной термоокислительной стабильностью.This invention relates to compositions of lubricating oils with enhanced thermo-oxidative stability.
Известны смазочные композиции на основе синтетических масел, содержащие трикрезилфосфат и в качестве антиокислительной присадки алкилированный дифениламин.Synthetic oil-based lubricating compositions containing tricresyl phosphate and alkylated diphenylamine as an antioxidant additive are known.
Недостаток известной смазочиой композиции заключаетс в том, что она не может быть применена в услови х низких температур .A disadvantage of the known lubricant composition is that it cannot be applied under conditions of low temperatures.
Предлагаетс в состав смазочной композиции вместо алкилированного дифениламина вводить арилалкилпроизводное дифениламина (4,4-диметилбензил) -дифениламин.It is proposed to introduce arylalkyl derivative of diphenylamine (4,4-dimethylbenzyl) -diphenylamine instead of the alkylated diphenylamine in the lubricant composition.
Состав предложенной смазочной композиции следующий, вес. %:The composition of the proposed lubricant composition following weight. %:
Трикрезилфосфат3-5Tricresyl phosphate 3-5
(4,4-Диметилббнзил) дифениламин1 ,5-2(4,4-Dimethylbnzyl) diphenylamine1, 5-2
Синтетическое маслоДо 100Synthetic oil up to 100
В качестве синтетического масла в предложенном составе используютс сложные эфиры пентаэритрита и синтетические жирные кислоты фракции Cs-Cg.As a synthetic oil, pentaerythritol esters and synthetic fatty acids of the Cs-Cg fraction are used in the proposed composition.
В состав смазочной композиции дополнительно может быть введена противозадирна присадка совол, котора улучшает смазочную способность всей композиции.The lubricant composition may additionally contain an anti-seize additive, Sovol, which improves the lubricity of the entire composition.
Трикрезилфосфат, вл ющийс известной противозадирной присадкой, кроме того, усиливает антиокислительное действие (4,4-диметилбензил ) -дифениламина.Tricresyl phosphate, which is a known anti-seize additive, also enhances the antioxidant effect of (4,4-dimethylbenzyl) -diphenylamine.
Как видно из данных таблицы, наибольшейAs can be seen from the data table, the greatest
термоокислительной стабильностью обладает композици , включающа в себ (4,4-димстилбензил )-дифениламин и Трикрезилфосфат. Повышение в зкости этой композиции после окислени почти в 3 раза меньше, чем у композиции , где вместо трикрезилфосфата используетс ди-(2-этилгексил) - фосфориста кислота.thermo-oxidative stability is possessed by a composition comprising (4,4-dimstilbenzyl) -diphenylamine and tricresyl phosphate. The increase in viscosity of this composition after oxidation is almost 3 times less than that of the composition, where di- (2-ethylhexyl) -phosphorous acid is used instead of tricresyl phosphate.
Противозадирные свойства наиболее высоки у предлагаемой композиции в сочетании сAnti-seize properties are highest in the proposed composition in combination with
противозадирной присадкой совол.anti-seize additive sovol.
Предложенна смазочна композици , нар ду с высокой термоокислительной стабильностью и улучшенными противозадирными свойствами, обладает тем преимуществом, чтоThe proposed lubricant composition, along with high thermo-oxidative stability and improved extreme pressure properties, has the advantage that
быть использована в услови х низких температур. be used in low temperature conditions.
