Abstract

The invention discloses a formula of a wear-resistant and oxidation-resistant hydraulic oil composite agent, which comprises, by mass, the following components: 10-25% of long-chain primary alcohol dialkyl dithiophosphate zinc, 10-30% of di-tert-butyl-p-cresol, 0-15% of alkylated diphenylamine, 10-25% of tricresyl phosphate, 1-10% of high-base-number synthetic calcium sulfonate, 1-10% of dipolyisobutylene imide, 0-1% of dodecenyl succinic acid half ester, 1-8% of basic barium dinonylnaphthalene sulfonate, 1-3% of benzotriazole octadecylamine salt and 10-30% of base oil. The invention also discloses a preparation process of the composite agent, which comprises the following steps of: adding the hydraulic oil composite agent into a reaction kettle according to the mass percentage of each component in the formula of the hydraulic oil composite agent, heating to 70-80 DEG C, and stirring and cooling. The hydraulic oil prepared by the composite agent matched with the base oil has excellentoxidation and corrosion resistance, excellent abrasion resistance and better cleaning and dispersing performances.

Description

technical field [0001] The invention relates to the technical field of lubricating oil. More specifically, the present invention relates to the anti-wear and anti-oxidation hydraulic oil compound formulation and its preparation process. Background technique [0002] Hydraulic oil is an important part of hydraulic technology, which is used to realize energy conversion, transmission and control in the hydraulic system. At the same time, it also plays the role of lubrication, anti-rust, anti-corrosion and cooling of the system. People regard the oil pump in the hydraulic system as the heart, and the hydraulic oil is the blood of the system. The hydraulic system is widely used in various mechanical equipment. Driven by the motor, the hydraulic oil is converted from mechanical energy to pressure energy through the pump. [0003] The existing anti-wear hydraulic oil is produced in accordance with national standards, and the standard does not include the cleanliness and dispersi...
