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 friction-reducing and anti-wear biodegradable hydraulic oil, 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 dialkyldithiophosphate 3.5, antioxidant 10101.5, Nano molybdenum disulfide 6.

[0015] The biodegradable hydraulic oil for anti-friction and anti-wear 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 oleic acid into a reaction kettle, add trimethylolpropane and toluenesulfonic ac...

Abstract

The invention discloses anti-friction and wear-resistant biodegradable hydraulic oil. The anti-friction and wear-resistant biodegradable hydraulic oil is prepared from the following raw materials in parts 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 nano boron carbide particles, 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 ethoxyl imidazoline, 10-12 parts of polymethacrylate, 3.5-4 parts of zinc dialkyl dithiophosphate, 1.5-2 parts of an antioxidant, and 6-7.5 parts of nano molybdenum disulfide. By addition of the nano molybdenum disulfide, good synergistic effect is achieved during compounding and using, and meanwhile, friction performance of base oil can be improved obviously; and the product is biodegradable and environmentally friendly, and has good performance during actual use.

Description

technical field [0001] The invention relates to the technical field of hydraulic pressure, in particular to a biodegradable hydraulic oil for anti-friction and anti-wear. 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 perfor...
