Problems solved by technology

However, ordinary hydraulic oils are not good enough for medium and high pressure hydraulic systems. At the same time, the viscosity-temperature performance is unstable. At high or low temperatures, especially under the action of strong shear, its viscosity The change is very large, and the role of hydraulic oil cannot continue to be completed
[0004] At the same time, at high temperature, the base oil will undergo oxidation reaction to produce acidic substances, which will corrode the metal and produce a large amount of colloid, which will greatly affect the stability of the oil.

Embodiment approach

[0028] As an embodiment of the present invention, in parts by weight, the anti-wear hydraulic composition includes:

[0029]

[0030]

[0031] base oil

[0032] In the present invention, the base oil is selected from base oils of mineral oil, synthetic oil and mixtures thereof.

[0033] As an embodiment of the present invention, the mineral oil is selected from Group III mineral oils.

[0034] As an embodiment of the present invention, the synthetic base oil is selected from one or more of PAO synthetic oil, ester synthetic oil, and polyether synthetic oil.

[0035] The advantages of ester oil: the oxidation stability and thermal stability of the inhibitor are better than that of mineral oil, the use temperature is high, the pour point is low, and the low temperature fluidity is good; the viscosity temperature performance is good, and it can be synthesized with mineral oil and other kinds Oil miscible, good anti-wear, anti-chafe properties; low volatility, non-toxic, ...

Embodiment 1

[0082] Embodiment 1: This embodiment provides an energy-saving anti-wear hydraulic oil, which includes:

[0083]

[0084]

[0085] The base oil is a mixture of ester synthetic oil and Group III mineral oil at a weight ratio of 1:1; the ester synthetic oil is purchased from Dongxu Chemical Factory in Yingkou City, the brand is Kelubo, and the specification model is 4027.

[0086] The wear reducing agent is bis-octyl zinc salt of thiophosphor.

[0087] Described antioxidant is hindered phenol type antioxidant, and preparation method is as follows:

[0088] S01 Put 0.02mol 4-ethyl-3-hydroxybenzoic acid into a dry 250mL reactor, add 50mL chloroform, after dissolving, slowly add 4mL thionyl chloride dropwise under the protection of nitrogen, and then react at 50°C After 5h, the reaction was distilled under reduced pressure to remove the solvent and unreacted thionyl chloride to obtain the product 1;

[0089] S02 Add 0.002mol of polyamide-amine polymer, 7ml of distilled wate...

Embodiment 2

[0097] Example 2: The difference between the implementation of this example and Example 1 is that this example provides an energy-saving anti-wear hydraulic oil, which includes:

Abstract

An energy-saving anti-wear hydraulic oil comprises base oil, anti-friction agent, antioxidant, anti-foaming agent and anti-emulsifying agent. The energy-saving anti-wear hydraulic oil provided by the invention has excellent anti-corrosion and anti-wear properties; the energy-saving anti-wear hydraulic oil provided by the invention has good fluidity under low temperature conditions, and small viscosity difference between low temperature and high temperature conditions. The sealing performance and lubricating performance of the hydraulic oil are better balanced; the anti-wear hydraulic composition provided by the invention can effectively reduce the energy consumption when the hydraulic device is started in actual use, and has good energy-saving performance, high stability and long service life. long features.

Description

technical field [0001] The invention relates to the technical field of lubricating oil production, in particular to an energy-saving anti-wear hydraulic oil. Background technique [0002] In actual production, energy must be controlled, converted and transmitted. There are many ways to transfer energy, which can be divided into four categories: mechanical transmission, electric transmission, pneumatic transmission and hydraulic transmission. [0003] The medium that transmits energy in hydraulic transmission, that is, hydraulic oil, plays many important roles in hydraulic machinery. Conventional performance requirements for hydraulic oil are: good viscosity-temperature performance; excellent performance in preventing rust and corrosion of metal materials; good oxidation resistance; good anti-emulsification performance. However, ordinary hydraulic oils are not good enough for medium and high pressure hydraulic systems. At the same time, the viscosity-temperature performance...
