Problems solved by technology

However, with the strengthening of people's awareness of environmental protection and the increasingly stringent environmental regulations, the development and use of biodegradable lubricating oils has attracted more and more attention. Most hydraulic base oils have poor biodegradability and are biodegradable lubricating materials.
This article does not address the degradability of hydraulic oils and the oxidation resistance of degradable base oils

Embodiment Construction

[0014] A synthetic hydraulic oil with anti-oxidation and long service life, prepared from the following raw materials in parts by weight (kg): industrial oleic acid 280, elemental iodine 12.6, acrylic acid 72, trimethylolpropane 134, toluenesulfonic acid 15, nano Boron carbide particles 15, Span 800.8, sodium carboxymethylcellulose 2, deionized water 30, hydroxyethyl imidazoline 3.2, polymethacrylate 10, zinc dialkyl dithiophosphate 3.5, thioaminomethyl Ester 2.5, octylated diphenylamine 1.2, ferrocene 2, fumed silica 0.5, isophorone diisocyanate 0.4.

[0015] The synthetic hydraulic oil with a long anti-oxidation service life is made by the following specific steps:

[0016] (1) Put industrial oleic acid into the reaction kettle, heat to 200°C, add elemental iodine, stir evenly, continue to add acrylic acid, stir and react for 2 hours at a speed of 300 rpm, and separate and refine the crude product after natural cooling , to obtain high-purity oleic acid; put high-purity ole...

Abstract

The invention discloses anti-oxidation synthesized hydraulic oil with long service life. The synthesized hydraulic oil is prepared from raw materials in parts by weight as follows: 280-285 parts of industrial oleic acid, 12.6-13 parts of iodine, 72-74 parts of acrylic acid, 134-135 parts of trimethylolpropane, 15-16 parts of toluenesulfonic acid, 15-17 parts of nano boron carbide granules, 0.8-1 part of span 80, 2-3 parts of sodium carboxymethylcellulose, 30-32 parts of deionized water, 3.2-3.5 parts of hydroxyethyl imidazoline, 10-12 parts of polymethacrylate, 3.5-4 parts of zinc dialkyl dithiophosphate, 2.5-3 parts of thiocarbamate, 1.2-1.5 parts of octylated diphenylamine, 2-3 parts of ferrocene, 0.5-0.7 parts of fumed silica and 0.4-0.5 parts of isophorone diisocyanate. The prepared product can reduce friction, is wear-resistant and can be used for a long time, the wear resistance of a friction pair can be effectively reduced, the service life of equipment can be prolonged, and the maintenance cost of the equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of hydraulic pressure, in particular to a synthetic hydraulic oil with long anti-oxidation service life. Background technique [0002] In recent years, with the development and improvement of hydraulic system design and manufacturing technology, hydraulic technology has been widely used in the new generation of mechanical equipment. The variability of the working environment of hydraulic machinery brings great challenges to hydraulic oil: hydraulic oil must withstand the test of high pressure, high temperature, temperature changes, and harsh environments. It needs to have excellent viscosity-temperature performance and high load-bearing capacity to ensure mechanical However, the existing anti-wear hydraulic oil is difficult to fully meet the complex and changeable working conditions of the hydraulic system. The widely used anti-wear hydraulic oil has a low viscosity index and poor viscosity-temperature perf...
