Problems solved by technology

[0003] At present, various anti-wear hydraulic oils have been developed on the market, but most of them start to solve the problems of anti-oxidation stability, thermal stability and extreme pressure lubricity from the aspect of additives. The base oil used has not been improved, and The quality of the base oil has a direct impact on the performance of the anti-wear hydraulic oil, and the additives only play an auxiliary role
Usually, the base oil contains more impurities, such as sulfur, nitrogen, aromatic hydrocarbons, heterocycles, colloids and other substances. These impurities are easy to oxidize and deteriorate under the action of high temperature. Oxidation is one of the important reasons for the deterioration of hydraulic oil quality. First, the existing methods are difficult to completely remove the above-mentioned impurities, thus affecting the anti-oxidation stability, thermal stability and other properties of the prepared anti-wear hydraulic oil

Abstract

The invention discloses anti-wear hydraulic oil and a preparation method thereof. The anti-wear hydraulic oil comprises the following raw materials, by weight part, 90-100 parts of base oil, 2-4 parts of tritolyl phosphate, 6-8 parts of zinc dialkyl dithiophosphate, 0.5-1 part of a thiadiazole derivative, 5-7 parts of polymethacrylate, 2-4 parts of barium dinonylnaphthalene sulfonate, and 3-5 parts of an adsorbent, wherein the base oil is I-kind base oil, and the adsorbent is a mixture of bentonite and halloysite, wherein the mass ratio of bentonite to halloysite is 1:0.4-0.6. According to the method, pre-treated bentonite and halloysite are taken as an adsorbent, and since the bentonite and halloysite have certain preference selection for adsorbing impurities in base oil, according to the matching ratio provided in the invention, impurities in base oil can be fast removed, thereby greatly improving the quality of base oil in the hydraulic oil. Since the impurities are completely removed, the hydraulic oil has better antioxidant stability and corrosion resistance than anti-wear hydraulic oil prepared in the prior art.

Description

technical field [0001] The invention belongs to the field of lubricating oil, and in particular relates to an anti-wear hydraulic oil and a preparation method thereof. Background technique [0002] Anti-wear hydraulic oil is an important part of hydraulic technology. The main function in the hydraulic system is to transmit the force applied by a certain point in the hydraulic system to other parts, and it also has the functions of lubrication, cooling and rust prevention. The reliability, accuracy and flexibility of the operation of the hydraulic system, in addition to relying on the design, material and performance of the hydraulic components of the equipment, also depends on the hydraulic oil to a large extent. With the continuous development of hydraulic system technology, the application of precision components is becoming more and more extensive. In order to ensure the smooth work of precision instruments, the quality of oil used in hydraulic systems is also gradually i...
