Abstract
The invention provides fire resistant hydraulic oil. The fire resistant hydraulic oil comprises the following components in parts by mass: 980-992 parts of 150N third type base oil, 2-5 parts of sulfurized polyisobutene, 5-6 parts of benzotriazole, 1.2-1.5 parts of sodium tripolyphosphate, 0.5-0.8 part of triazole fatty acid amine salt, 0.08-0.12 part of di-iso-octyldiphenylamine, a proper amount of demulsifier and 0.7-0.9 part of ethylenediamine tetraacetic acid. The invention also provides a preparation method of the hydraulic oil. The fire resistant hydraulic oil has good high temperature and low temperature stability, can be widely used in ironmaking, steelmaking, pressure casting, continuous casting, hot rolling, coal mining and glass product processing and in the hydraulic systems of various equipment which is close to heat sources and has fire dangers, such as excavators, is simple in preparation method, has good lubricating property, also has good abrasion resistance and causes small damages to oil pumps and hydraulic valves.
Description
Technical field
The present invention relates to a kind of fire resistant hydraulic oil.
Background technology
Hydrostatic transmission be by means of the liquid pressure that is in encloses container can transmission carry out operation element parts, because its volume is little, quality light, be quick on the draw, transmit steady, easy for installation, easy handling, thus the switch telechirics etc. of the steering wheel of boats and ships, windlass, navigationsystem and valve is widely used in, pressure medium is the medium of transferring energy in hydrostatic transmission, plays the vital role such as transferring energy, lubrication equipment, antiseptic and rustproof and cooling in hydraulic efficiency installation.If oil pump is the heart of whole hydraulic efficiency system, so pressure medium is exactly the blood of hydraulic efficiency system, and it plays vital effect to the working reliability of hydraulic efficiency system and life-span.A large amount of facts shows, the hydraulic fault of more than 70% is caused by working medium, and therefore, selecting properly and use pressure medium are all of great significance the serviceability and working reliability, security and prolongs life cycle that improve hydraulic efficiency system.The fire resistant hydraulic oil the most extensively adopted is at present water-ethylene glycol liquid, but it in use exists corroding metal and the problem such as oilness is bad.
