Degradable hydraulic oil added with oil-soluble nano titanium dioxide

Abstract

The invention discloses degradable hydraulic oil added with oil-soluble nano titanium dioxide. The degradable 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 particles, 0.8 to 1 part of Span 80, 2 to 3 parts of sodium carboxymethylcellulose, 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, 10 to 12 parts of nano titanium dioxide, 10 to 12 parts of dodecyltrimethoxysilane, 1.5 to 2 parts of sorbide oleate and 5 to 6 parts of chlorinated paraffin. The degradable hydraulic oil disclosed by the invention has good viscosity-temperature characteristic, such that the hydraulic oil has better viscosity and oil film thickness when used in a relatively wide temperature range.

Description

technical field [0001] The invention relates to the field of hydraulic technology, in particular to a degradable hydraulic oil added with oil-soluble nano-titanium dioxide. 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 perf...

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.
