Abstract

The invention provides a composition for inhibiting the generation amount of ZDDP oil sludge. The composition is composed of, in percent by mass, 12%-29.86% of alkyl phenate and alkyl phenate derivatives, 11.6%-23.89% of succinimide and succinimide derivatives or succinate and succinate derivatives, 8.47%-28.40% of alkyl diphenylamine and derivatives of alkyl diphenylamine and 40.96%-59.88% of phenolic compounds. ZDDP is an important reason for generation of the oil sludge during use of hydraulic oil, insoluble matter produced through decomposition of ZDDP can be reduced significantly throughthe composition, and agglomeration and deposition of the insoluble matter can also be prevented, so that the generation amount of the oil sludge is reduced; and the generation amount of the hydraulicoil sludge can be reduced significantly during actual use, blockage of pipelines and valves of hydraulic equipment can be avoided, abrasion can be reduced, and the composition has a simple preparationmethod and low manufacture cost.

Description

technical field [0001] The invention generally relates to the technical field of lubricating oil, in particular to a composition for inhibiting ZDDP sludge formation and application thereof. Background technique [0002] Sludge is an important product of oil oxidation and deterioration, which will have a serious impact on the hydraulic system, causing blockage of oil passages, filter elements, and wear of friction pairs. At the same time, sludge will also accelerate the deterioration of hydraulic oil. Due to the development of hydraulic equipment towards miniaturization, high pressure, high speed, large flow and automation, the requirements for hydraulic components are more stringent and the precision requirements are higher, which increases the sensitivity of the device to impurities. These particles are not only the pollution of foreign particles, but more importantly, the sludge produced by the oxidation and hydrolysis of the hydraulic oil itself. There are two main sour...
