Abstract
The invention discloses anti-wear and flame-resistant hydraulic oil. The anti-wear and flame-resistant hydraulic oil is prepared from raw materials in parts by mass as follows: 50-60 parts of NO.46 base oil, 8-11 parts of isopropyl palmitate, 6-9 parts of vulcanized polyisobutene, 5-8 parts of benzotriazole, 9-12 parts of fatty alcohol-polyoxyethylene ether, 7-10 parts of glyceryl monostearate, 6-8 parts of ethylenediamine tetraacetic acid, 3-5 parts of silicon dioxide, 5-9 parts of ethylene glycol, 6-8 parts of hydroxyethyl cellulose and 8-10 parts of lauroyl diethanolamide. The anti-wear and flame-resistant hydraulic oil has good wear resistance, an excellent extreme pressure property, remarkable corrosion prevention and rust prevention performance and good cooling performance.
Description
technical field [0001] The invention relates to the technical field of hydraulic oil, in particular to an anti-wear and anti-fire hydraulic oil. Background technique [0002] Hydraulic oil is the hydraulic medium used in hydraulic systems that utilize liquid pressure energy. It plays the roles of energy transmission, anti-wear, system lubrication, anti-corrosion, anti-rust, cooling, etc. in the hydraulic system. The hydraulic components of the high-pressure system, especially the friction pair in the boundary lubrication state in the hydraulic pump, have severe friction and wear conditions due to the increase of positive pressure and high speed, so hydraulic oil with excellent anti-wear and extreme pressure properties must be selected. The existing hydraulic oil has unsatisfactory anti-wear performance and poor extreme pressure performance, which brings a lot of inconvenience to the hydraulic system. Contents of the invention [0003] In order to solve the above existing ...
