Problems solved by technology

[0004] Although the water-ethylene glycol system has the above-mentioned advantages, it still has the following disadvantages: first, ethylene glycol is highly toxic, difficult to degrade after discharge, and is harmful to the environment; second, the anti-wear agent and anti-wear agent in the anti-wear hydraulic fluid Rust agents generally compete with each other for adsorption on the surface of the friction pair. When using different anti-wear agents and anti-rust agents, it is difficult to satisfy the anti-wear and anti-rust properties at the same time

Abstract

The invention discloses a triethanolamine phosphate ricinoleate compound and total-synthesized water-based anti-wear hydraulic fluid containing the compound, and belongs to the filed of lubricating oil production. The triethanolamine phosphate ricinoleate has excellent anti-wear and anti-rust properties, and is capable of synchronously satisfying the anti-wear and anti-rust property requirements of the hydraulic fluid. The hydraulic fluid is formed by mixing triethanolamine phosphate ricinoleate, viscosity modifier, dimethyl sulfoxide, water, benzotriazole, de-foaming agent and fungicide, has the following characteristics of energy saving, environmental friendliness, excellent anti-wear and anti-rust properties, and the like, and has high value in promotion and application.

Description

technical field [0001] The invention relates to the field of lubricating oil production, in particular to ricinoleic acid triethanolamine phosphate and a fully synthetic water-based anti-wear hydraulic fluid containing the compound. Background technique [0002] Hydraulic transmission technology is widely used in various fields due to its own series of characteristics. The working medium used in traditional hydraulic systems is mineral oil type, which is commonly referred to as hydraulic oil. In some applications with special requirements, such as coal mines, metallurgy, aviation, navigation, subsea oil exploration and other fields, the working medium used is non-petroleum emulsion or synthetic fluid, such as high water base fluid, water-glycol fluid, phosphate ester Liquids, etc., usually add various additives to water and base fluids to make them more suitable for traditional hydraulic systems. [0003] In recent years, due to the ever-increasing requirements for the saf...
