Synthetic hydraulic oil with excellent viscosity-temperature characteristics

Abstract

The invention discloses synthetic hydraulic oil with excellent viscosity-temperature characteristics. The synthetic hydraulic oil comprises, by weight, 280-285 parts of industrial oleic acid, 12.6-13 parts of elemental 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 sorbitan oleate, 2-3 parts of sodium carboxymethyl celluloses, 30-32 parts of deionized water, 3.2-3.5 parts of ethoxy imidazolidine, 10-12 parts of polymethacrylate, 3.5-4 parts of zinc dialkyl dithiophosphate, 15-17 parts of ethylene-propylene methylene copolymer powder, 0.1-0.12 part of dicumyl peroxide, 1.8-2 parts of maleic anhydride, 1-1.1 parts of melamine, 1-1.2 parts of isopropyl palmitate and 1.8-2 parts of alkenyl succinic acid ester. The synthetic hydraulic oil has the advantages that the synthetic hydraulic oil is excellent in viscosity-temperature characteristics and low-temperature starting performance, and the appropriate viscosity of the synthetic hydraulic oil can be kept at the high temperatures.

Description

Technical field [0001] The invention relates to the technical field of hydraulics, in particular to a synthetic hydraulic oil with good viscosity-temperature characteristics. 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 a new generation of mechanical equipment. The variability of the working environment of hydraulic machinery has brought great challenges to hydraulic oil: hydraulic oil must withstand the test of high pressure, high temperature, temperature change, and harsh environment. It needs to have excellent viscosity-temperature performance and high load-bearing capacity to ensure the machinery However, the existing anti-wear hydraulic oil cannot fully meet the complex and variable working conditions of the hydraulic system. The anti-wear hydraulic oil widely used now has a low viscosity index and poor viscosity-temperature performanc...

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.
