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

Abstract

The invention discloses a degradable synthetic hydraulic oil with good shearing stability. The degradable synthetic hydraulic oil with good shearing stability is prepared from, by weight, 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 nanometer boron carbide particles, 0.8-1 part of span80, 2-3 parts of carboxymethylcellulose sodium, 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, 2-3 parts of molybdate ester, 4-5 parts of ethylene-propylene copolymer rubber powder, 2.5-3 parts of polyalkylene glycol, 0.8-1 part of octadecylamine and 1.4-1.6 parts of quinazolinone amine. The degradable synthetic hydraulic oil has the advantages of good low-temperature performances, shearing resistance, maintenance of the viscosity and viscosity related performances unchanged, and prolonged service life.

Description

technical field [0001] The invention relates to the field of hydraulic technology, in particular to a degradable synthetic hydraulic oil with good shear stability. 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 performance. ...
