(54) СМАЗОЧНАЯ КОМПОЗИЦИЯ(54) LUBRICATING COMPOSITION

1one

Изобретение относитс  к составам смазочных масел, в частности к композици м автомобильного и дизельного картерного смазочного масла, содержащим небольшое количество маслорастворимых присадок нового класса , улучшающих характеристики масла, особенно его диспергирующе-детергентные свойства .The invention relates to lubricating oil compositions, in particular to automotive and diesel crankcase lubricating oil compositions, containing a small amount of oil-soluble additives of a new class that improve the characteristics of the oil, especially its dispersing and detergent properties.

Современные автомобильные и дизельные двигатели рассчитаны на высокую мощность, незначительное выделение продуктов сгорани  и длительную службу картерного смазочного масла. Это требует очень жестких рабочих условий, кроме того, необходимы высокоэффективные смазочные масла, обеспечивающие при повышенных эксплуатационных требовани х защиту от коррозии и накоплени  углеродистых отложений, нагара и смолистых продуктов на поверхности деталей двигател , быстро снижающих эффективность и срок службы двигател . Даже при высокой степени очистки базового смазочного масла от вредных компонентов, например полимеризирующихс  компонентов, кислотообразующих, восков и тому подобное, оно тем не менее нуждаетс  в добавке р да маслорастворимых химических присадок, придающих маслу способность противосто ть окислению, отложениюModern automobile and diesel engines are designed for high power, low emission of combustion products and long service life of crankcase lubricating oil. This requires very harsh operating conditions, in addition, high-performance lubricating oils are required, which provide protection against corrosion and accumulation of carbon deposits, carbon deposits and tarry products on the surface of engine parts, which quickly reduce the efficiency and service life of the engine, with increased operational requirements. Even with a high degree of purification of the base lubricating oil from harmful components, such as polymerizing components, acid-forming, waxes, and the like, it nevertheless needs to be supplemented with a number of oil-soluble chemical additives that give the oil the ability to resist oxidation, deposition

осадков или нагара и коррозии смазываемых металлических частей и способность регулировать смазочные свойства и в зкость при изменении температуры.precipitation or soot and corrosion of lubricated metal parts and the ability to regulate lubricity and viscosity with temperature.

Продукты сгорани , образующиес  в результате сгорани  топлива и термического разложени  смазочных масел и присадок, склонны накапливатьс  в картерном масле с образованием маслонерастворимых продуктов,The combustion products resulting from the combustion of fuel and the thermal decomposition of lubricating oils and additives tend to accumulate in the crankcase oil to form oil-soluble products,

образующих нагар или лакоподобные пленки, или оседающих на част х двигател  в виде в зких отложений, или образующих твердые золоподобные или углеродистые отложени . Отложени  могут сузить и даже закупоритьforming carbon or lakopodobny films, or deposited on the engine parts in the form of viscous deposits, or forming solid ash-like or carbonaceous deposits. Deposits can narrow and even block

пазы, канавки и полости, по которым масло подаетс  к движущимс  поверхност м двигател  и тем самым ускорить износ и, следовательно , снизить эффективность двигател . Кроме того, кислые продукты сгорани  корродируют смазываемые металлические поверхности .grooves, grooves and cavities through which the oil is supplied to the moving surfaces of the engine and thereby accelerate wear and, consequently, reduce the efficiency of the engine. In addition, acidic combustion products corrode lubricated metal surfaces.

Дл  обеспечени  детергентно-диспергирующих свойств были предложены различные ингредиенты . Первыми присадками указанногоVarious ingredients have been proposed to provide detergent dispersing properties. The first additives specified

назначени   вились нейтральные или щелочные металлорганические производные, например соли щелочноземельных металлов и суль фокислот и продукты реакции углеводород  Neutral or alkaline organometallic derivatives, such as alkaline earth metal salts and sulfonic acids and hydrocarbon reaction products, were used.

п тисернистым фосфором. Однако эти присадки образуют продукты термического разложени , способствующие отложению золы на част х двигател . Они не могут эффективно диспергировать образующиес  лаки, нагары или углеродистые отложени , тер ют диспергирующе-детергентные свойства при расходовании их щелочноземельного компонента на нейтрализацию кислых продуктов сгорани .n graded phosphorus. However, these additives form thermal decomposition products that contribute to the deposition of ash on engine parts. They cannot effectively disperse the resulting lacquers, carbon deposits or carbon deposits, lose dispersing and detergent properties when their alkaline earth component is spent on neutralizing acidic combustion products.

Примен ют также в качестве присадок продукты конденсации по Манниху, полученные из алкилзамещенных оксиароматических соединений , у которых алкил имеет относительно невысокий молекул рный вес (2-20 углеродных атомов в алкиле) и алкильные заместители типа хлорированного воска. Однако ни один из подобных продуктов конденсации не пригоден дл  использовани  в качестве детергснтно-диспергирующей присадки дл  современных масел продолжительной эксплуатации. Mannich condensation products obtained from alkyl-substituted hydroxy aromatic compounds, in which alkyl has a relatively low molecular weight (2-20 carbon atoms in alkyl) and alkyl substitutes of the type of chlorinated wax, are also used as additives. However, none of these condensation products is suitable for use as a detergent-dispersant additive for modern long-life oils.

Известны смазочные композиции, содержащие в качестве детергентно-диспергирующих присадок высокомолекул рные продукты конденсации алкилзамещенных окснароматических соединений, алкильный заместитель которых имеет мол. в. 600-3000, с амином, содержащим не менее одной NH-группы, и альдегидом . Раствор подобных высокомолекул рных продуктов конденсации, особенно в легких маслах, в процессе хранени  образует нерастворимые или малорастворимые побочные продукты, которые не только почти невозможно удалить путем фильтрации, но которые сильно снижают скорость фильтрации самого продукта.Lubricating compositions are known which contain, as detergent-dispersant additives, high-molecular-weight condensation products of alkyl-substituted oxnaromatic compounds, whose alkyl substituent has a mol. at. 600-3000, with an amine containing at least one NH group, and an aldehyde. A solution of such high molecular weight condensation products, especially in light oils, forms insoluble or poorly soluble by-products during storage, which are not only almost impossible to remove by filtration, but which greatly reduce the filtration rate of the product itself.

При использовании их в картерном смазочном масле в результате высокой температуры в канавках поршневых колец образуютс  углеродистые отложени  и быстро накапливаетс  нагар, мещающий длительной эксплуатации смазочного масла.When used in crankcase lubricating oil, as a result of the high temperature, carbon deposits form in the grooves of the piston rings and carbon deposits quickly accumulate, prolonging the long-term use of lubricating oil.

Целью изобретени   вл етс  улучшение детергентно-диспергирующих и антиокислительных свойств композиции.The aim of the invention is to improve the detergent-dispersant and antioxidant properties of the composition.

Поставленна  цель достигаетс  тем, что в состав композиции введен продукт конденсации алкилзамещенного оксиароматического соединени , алкильный заместитель которого имеет мол. в. 600-100000, амина, содержащего не менее одной NH-группы, алифатического альдегида и алифатической кислоты, содержащей не менее 6 атомов углерода, в количестве 0,05-70 вес.%.This goal is achieved by the fact that the composition contains the condensation product of an alkyl-substituted hydroxyaromatic compound, the alkyl substituent of which has a mol. at. 600-100000, amine containing at least one NH-group, aliphatic aldehyde and aliphatic acid containing at least 6 carbon atoms, in an amount of 0.05-70 wt.%.

Предцочтительными  вл ютс  продукты конденсации полиалкилфенола с мол. в. 850- 2500, этилениолиамина, формальдегида и алифатической кислоты.Preferred are the condensation products of polyalkylphenol mol. at. 850 2500, ethylenediamine, formaldehyde and aliphatic acid.

Такие высокомолекул рные продукты  вл ютс  эффективными присадками к смазочным маслам, придающими последним диспергирующе-детергентные и антиокислительные свойства при относительно низкой концентрации присадок (0,05-10 вес.%, счита  на смазочвое масло). Более высокие концентрации, например пор дка 10-70 вес.%, пригодны дл  концентратов, используемых дл  получени  смазочных масел и укреплени  картерного масла.Such high molecular weight products are effective additives to lubricating oils, which impart the dispersant-detergent and antioxidant properties of the latter with a relatively low concentration of additives (0.05-10 wt.%, Based on lubricating oil). Higher concentrations, e.g. on the order of 10-70% by weight, are suitable for concentrates used to prepare lubricating oils and to strengthen crankcase oil.

Указанные высокомолекул рные продукты получают известными способами конденсации по Манниху, загружа  высокомолекул рное алкилзамещенное оксиароматическое соединение (1), амин (2), альдегид (3) и алифатическую кислоту (4) в мол рных соотношени х 1,0:0,1 - 10 : 1,0-10 : 0,014-1,0. Реакцию целесообразно вести так, чтобы в нагретую от комнатной температуры до 93°С (200°F) смесь соединений 1, 2 и 4 вводить формальдегид (например, формалин) в среде легкого отгон емого органического растворител , например бензола, ксилола или толуола , или в среде очищенного нейтрального масла и затем реакцию вести при повышенной температуре 135-190,5°С (275-375Т), предпочтительно продува  реакционную массу инертным газом, например азотом, углекислым газом и тому подобное, до завершени  дегидратации .These high molecular weight products are prepared according to known Mannich condensation methods, loading high molecular weight alkyl substituted hydroxyaromatic compound (1), amine (2), aldehyde (3), and aliphatic acid (4) in molar ratios of 1.0: 0.1 to 10 : 1.0-10: 0.014-1.0. It is advisable to conduct the reaction in a mixture of compounds 1, 2 and 4 heated from room temperature to 93 ° C to introduce formaldehyde (for example, formalin) in a light distilled organic solvent, for example benzene, xylene or toluene, or in a purified neutral oil medium and then the reaction is carried out at an elevated temperature of 135-190.5 ° C (275-375T), preferably by flushing the reaction mass with an inert gas, for example nitrogen, carbon dioxide and the like, until the dehydration is complete.
