Description
Technical Field
The present invention generally belongs to the technical field of lubricating oil, and particularly relates to a composition for improving ZDDP filterability and application thereof.
Background
As the hydraulic equipment develops towards miniaturization, high pressure, high speed, large flow and automation, the requirements on hydraulic elements are more strict, the precision requirement is higher, the sensitivity of the device to impurities is increased, and the equipment is abraded and fails as long as tiny impurity particles exist; on the other hand, when the hydraulic oil is contaminated with water during use, the water causes additives in the oil to decompose, and the decomposition products are deposited on the surface of the filter, with the possibility of increasing the tendency of the filter to clog. So that the hydraulic oil is required to have good filterability. In the working environment of hydraulic systems and equipment, water is an inevitable interference factor, so that the influence of water on the performance of oil products is more and more concerned, and especially in large systems containing fine filters, the requirement on the wet filtration performance of the oil products is higher and higher. Industrial equipment hydraulic system, because its operating mode is mild relatively, the oil tank is great, even the entering of a small amount of water subsides at the oil tank bottom under the demulsifier effect, and is less to the practicality influence, and among the mobile device, the oil tank is general less, and better filterability is crucial to the operation of system and uses, also becomes among the engineering machine tool hydraulic oil, especially zinc-containing hydraulic oil, the difficult balanced performance. It is known that ZDDP is the main cause of poor filterability of hydraulic oils and that ZDDP may be converted into the corresponding double salt form in the presence of water, and this unstable double salt adversely affects the filterability of hydraulic oils and blocks the filter.
The filterability of the existing hydraulic oil compound additive is not outstanding, many compound additives only pass an SH/T0210 test method, but do not use a harsh SH/T0805 test method, and a ZDDP hydrolysate is difficult to meet the filtration requirement of precision hydraulic equipment. And the suppliers of the hydraulic oil complexing agent are relatively few, the price is relatively high, many hydraulic oil manufacturers basically use several single agents for blending to produce the hydraulic oil, and the additive system can not effectively improve the problem of the filtering property of the ZDDP.
Disclosure of Invention
The object of the present invention is to solve the above problems in the art and to provide a composition for improving the filterability of ZDDP, which is effective in improving the problem of poor filterability caused by ZDDP, ensuring that the filters of hydraulic equipment are not clogged, while ensuring the efficacy of hydraulic oil in the presence of water.
The technical scheme of the invention is that the composition for improving the filtering property of the ZDDP comprises the following components in percentage by mass:
succinimide and its derivatives or succinate and its derivatives: 14.5 to 23.9 percent; alkyl diphenylamines and their derivatives: 10.30-18.40%; a phenolic compound: 51.1-69.88%; a sulfonate compound: 4 to 11.2 percent; carboxylic acids and salts thereof: 0.8 to 8.2 percent.
The succinimide and the derivatives thereof, the succinate and the derivatives thereof and the sulfonate compound generate a synergistic effect to dissolve hydrolysis products in the oil and prevent agglomeration. The phenolic compound and the alkyl diphenylamine can react with the transfer chain carrier to change the transfer chain carrier into an inactive substance and play a role in terminating oxidation. The carboxylate chelates metal ions in the hydrolysate and cooperates with other components to reduce precipitate formation.
Further, the succinimide and the derivative thereof are one or a mixture of more than two of mono-succinimide, di-succinimide, poly-succinimide and boronized polyisobutenyl succinimide. The succinimide oily group can effectively form a three-dimensional barrier film, so that the hydrolysis products cannot be mutually aggregated. In addition, the succinimide has a high ionization polarity, and larger particles can be peptized by charge repulsion to be dispersed in the oil.
Further, the succinate and the derivative thereof are polyisobutylene succinate.
Further, the alkyl diphenylamine and the derivative thereof are one or a mixture of two or more of alkylated diphenylamine, styryl octyl diphenylamine, nonyl diphenylamine, N' -sec-butyl-p-phenylenediamine, and N-phenyl- α -naphthylamine.
Further, the above-mentioned phenol type compound is 2, 6-tert-butyl-p-cresol, 2, 4-dimethyl-6-tert-butylphenol, 4-thiobis (2-tert-butyl-6-methylphenol).
Further, the above sulfonate compound is petroleum sulfonate or dinonylnaphthalene sulfonate. The sulfonate compound has lipophilic group and hydrophilic group, and has strong cleaning effect, and the lipophilic group can combine with hydrolysis and oxidation products to dissolve in oil.
Further, the carboxylic acid and its salt are one or a mixture of more than two of dodecenylsuccinic acid, zinc naphthenate and barium petroleum sulfonate. The carboxylate salt can form a chelate with the hydrolysate to allow it to be dispersed in the oil without agglomeration.
The invention provides application of the composition for improving the filtering property of the ZDDP, which is applied to the addition, production and manufacture of any hydraulic oil in engineering machinery, industrial machinery, agricultural machinery, aviation equipment, marine equipment and automobile industry.
The present invention also provides a method of making the above composition for improving ZDDP filterability: mixing succinimide and its derivatives or succinate and its derivatives, alkyl diphenylamine and its derivatives, phenol compound, sulfonate compound, carboxylic acid and its salts, heating to 75-90 deg.C, stirring for 60-420 min, and filtering to obtain the final product.
The invention has the advantages that: the existing filterability improvement method mainly selects ZDDP with lower activity as a main agent of hydraulic oil, which can greatly increase the cost of the hydraulic oil. Compared with the prior ZDDP, the filterability can be greatly improved and the cost of hydraulic oil can be controlled by adding the composition. The preparation method is simple and easy to operate, and the prepared product is low in price, but can remarkably improve the main problem of the filtering property of the ZDDP, so that the key performance of the filtering property of the hydraulic oil is solved.
