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 excellent compatibility with sealing materials, 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, liquid vitamin E0.4, castor oil 4, polyalphaolefin 3, overbased calcium sulfonate 1.6, stearyl alcohol 2, alkenyl succinic acid half ester 2.5.

[0015] The synthetic hydraulic oil with excellent compatibility with sealing materials 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...

Abstract

The invention discloses a synthetic hydraulic oil with excellent compatibility with a sealing material. The synthetic hydraulic oil 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,0.4-0.5 parts of liquid vitamin E, 4-5 parts of castor oil, 3-4 parts of polyalpha-olefin, 1.6-2 parts of overbased calcium sulfonate, 2-3 parts of stearyl alcohol and 2.5-3 parts of alkenyl succinic acid semi-ester. A formula composition with good compatibility with a rubber sealing material, adopted in the invention, has no erosion effect on the sealing material and causes no pollution to hydraulic oil, so leakage is avoided.

Description

technical field [0001] The invention relates to the field of hydraulic technology, in particular to a synthetic hydraulic oil with excellent compatibility with sealing materials. 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-temperatur...
