High-pressure wear-resistant synthetic degradable hydraulic oil

Abstract

The invention discloses high-pressure wear-resistant synthetic degradable hydraulic oil. The hydraulic oil is prepared from the following raw materials in parts by weight: 280 to 285 parts of industrial oleic acid, 12.6 to 13 parts of iodine, 72 to 74 parts of acrylic acid, 134 to 135 parts of trimethylolpropane, 15 to 16 parts of toluenesulfonic acid, 15 to 17 parts of nano boron carbide particle, 0.8 to 1 part of Span 800, 2 to 3 parts of sodium carboxymethyl cellulose, 30 to 32 parts of deionized water, 3.2 to 3.5 parts of hydroxyethyl imidazoline, 10 to 12 parts of polymethacrylate, 3.5 to 4 parts of zinc dialkyl dithiophosphate, 6 to 7 parts of glyceryl monoricinoleate, 2 to 2.5 parts of aluminium stearate, 2 to 2.5 parts of sulfurized calcium alkyl phenate, 3 to 4 parts of silicone oil, 2.5 to 3 parts of nano polytetrafluoroethylene, and 0.7 to 0.9 part of succinimide. A product prepared by the invention can meet the lubrication requirement of a hydraulic system with high pressure, high speed and high power, has excellent wear resistance under the high pressure, and is biodegradable.

Description

technical field [0001] The invention relates to the field of hydraulic technology, in particular to a high-pressure anti-wear synthetic degradable hydraulic oil. 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. Th...

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.
