Problems solved by technology

However, general hydraulic oil cannot be directly used in aircraft, because the working conditions of aircraft engines are more severe
Aviation hydraulic oil is the most frequently used part of the hydraulic system such as aircraft landing gear. If the cleanliness, viscosity, acid value and other indicators exceed the standard, the solid particles and the surface of the hydraulic components will be worn, the internal leakage will increase, and it may even cause cavitation or jamming. Dead phenomenon, so that the system can not run,

Embodiment 1

[0059] Stir and mix 20kg of PAO2, 60kg of PAG680 and 20kg of dimethyl suberate in a reactor at room temperature for about 3 hours to form a compound base oil for later use. Then the temperature of the reactor was raised to about 80°C, and 20kg of antioxidant diisooctyl diphenylamine, 10kg of extreme pressure agent triphenylthiophosphate, 5kg of rust inhibitor nitrogen borate and 0.005kg of Stains Sudan Red IV and Oil Red O, continue to stir for about 2 hours until all components are evenly mixed. The reaction system was lowered to room temperature, and then antifoaming agent methyl silicone oil was added to the reactor until the concentration of the antifoaming agent was about 12ppm, and stirring was continued for about 1 hour to obtain the final low temperature fire-resistant hydraulic oil.

Embodiment 2

[0061] A low-temperature fire-resistant hydraulic oil was prepared in the same manner as in Example 1, except that various components were added according to the proportions shown in Table 1.

Embodiment 3

[0063] A low-temperature fire-resistant hydraulic oil was prepared in the same manner as in Example 1, except that various components were added according to the proportions shown in Table 1.

Abstract

The invention discloses a low temperature fire resistant hydraulic oil and a preparation method and applications thereof. PAO2, PAG680 and suberate are compounded to form the basic oil. Compared withdomestic aviation hydraulic oils for airplanes such as No.10 aviation hydraulic oil, No.15 aviation hydraulic oil, and the like and foreign similar products, the provided low temperature fire resistant hydraulic oil has better physical properties such as viscosity, flash point, and the like, meets related standards and requirements, and thus can be applied to fighter planes. Moreover, the providedhydraulic oil does not contain any anti-wear agent, but still meet the anti-wear requirement.

Description

technical field [0001] The invention belongs to the field of petrochemical product development, and in particular relates to a low-temperature fire-resistant hydraulic oil, a preparation method thereof and an application thereof. Background technique [0002] Hydraulic oil is a hydraulic medium used in a hydraulic system that utilizes liquid pressure energy. It plays the roles of energy transmission, anti-wear, system lubrication, anti-corrosion, anti-rust, cooling, etc. in the hydraulic system. For hydraulic oil, first of all, it should meet the requirements of the hydraulic device for the viscosity of the liquid at the working temperature and the starting temperature. Low-temperature fire-resistant hydraulic oil is a kind of fire-resistant hydraulic oil with automatic flame extinguishing function. It not only has excellent anti-oxidation, anti-wear, anti-rust and anti-foam properties, but also can cause fire when the oil is in contact with flames or hot surfaces. and the ...
