Problems solved by technology

However, the working pressure of the water-containing fire-resistant hydraulic fluid is generally lower than 10Mpa, and the lubricity is poor, which cannot meet the long-life service requirements of the hydraulic system under high temperature and high pressure conditions.
Due to the constraints of material adaptability, toxicity, price and increasingly stringent environmental protection requirements, the scope of use of non-aqueous phosphate ester and chlorinated hydrocarbon fire-resistant hydraulic oils will be increasingly restricted

Abstract

The invention belongs to the field of chemical engineering, and relates to an environment-friendly, energy-saving, totally-synthesized, and wear-resistant hydraulic oil and a preparation method thereof. The hydraulic oil comprises the following components: base oil, an extreme pressure anti-wear additive, an antioxidant, an antirust component, a viscosity index improver, and an antifoaming agent, wherein the base oil is a mixture of 3-ethyl-1-hexyl imidazole trifluorosulfonate and alkenes, and the extreme pressure anti-wear additive is zinc dialkyl dithiophosphate. The preparation comprises two parts: preparing 3-ethyl-1-hexyl imidazole trifluorosulfonate and mixing raw materials. The synthesized ionic liquid has the advantages of excellent thermal oxidation stability, high viscosity index, good dissolving performance on inorganic salts and organic matters, and good anti-wear and friction reducing effect; and the ionic liquid is taken as the basic liquid to prepare the environment-friendly, energy-saving, and wear-resistant hydraulic oil. The preparation method greatly promotes the development of anti-ware hydraulic oil to directions of environmental compatibility, biodegradability, and renewability, and the ionic liquid may be applied to the practical application of liquid oil.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to the preparation of hydraulic oil, in particular to an environment-friendly, energy-saving fully synthetic anti-wear hydraulic oil and a preparation method thereof. Background technique [0002] Hydraulic machinery has been widely used in industries such as iron and steel, electric power, coal and machinery. As a power medium, hydraulic oil is the key material of hydraulic transmission technology, and it is also one of the three important oil products with the largest consumption of industrial lubricating oil. With the continuous development of modern hydraulic technology, some hydraulic systems often work under high pressure and high temperature conditions. More stringent requirements are placed on the flame resistance of the hydraulic oil used. However, the operating pressure of water-containing fire-resistant hydraulic fluid is generally lower than 10Mpa, and its lubricity is po...
