Abstract
The invention discloses low-temperature fire-resistant hydraulic oil which is characterized by consisting of the following components in percentage by mass: 50-65% of basic oil, 18-28% of epoxy soybean oil, 0.8-0.9% of ethylenediaminetetraacetic acid, 3-5% of an anti-corrosion antirust agent, 2-3% of vulcanized polyisobutene, 6-10% of tri-isobutyl phosphate, 2-3% of benzotriazole, 0.5-0.8% of sodium tripolyphosphate, 0.6-0.9% of di-iso-octyldiphenylamine and 0.2-0.3% of polymethacrylate. The low-temperature fire-resistant hydraulic oil is good in high-temperature stability, can be widely applied to iron-making, steel-making, die casting, continuous casting, hot rolling, coal and glass product machining and hydraulic systems of equipment such as an excavator which is close to a heat source and has the potential of fire danger, is also applicable to alpine regions with relatively low ambient temperature, is good in lubrication property, and is small in damage to oil pumps, hydraulic valves, and the like.
Description
Technical field
The present invention relates to chemical technology field, be specially a kind of low temperature 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.And owing to needing to select the hydraulic efficiency oil being applicable to differing temps at different temperature, therefore need to change, considerably increase labor capacity and working time, we propose a kind of low temperature fire resistant hydraulic oil, go for different working temperatures for this reason.
Summary of the invention
The object of the invention is to a kind of low temperature fire resistant hydraulic oil, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme: a kind of low temperature fire resistant hydraulic oil, it is characterized in that being made up of the quality proportioning of base oil 50-65%, epoxy soybean oil 18-28%, ethylenediamine tetraacetic acid (EDTA) 0.8-0.9%, corrosion prevention rust preventer 3-5%, sulfurized polyisobutylene 2-3%, tri 6-10%, benzotriazole 2-3%, tripoly phosphate sodium STPP 0.5-0.8%, di-iso-octyldiphenylamine 0.6-0.9% and polymethacrylate 0.2-0.3%.
Preferably, described corrosion prevention rust preventer is made up of one or more in monoethanolamine, diethanolamine and trolamine and carboxylic acid reaction.
Compared with prior art, the invention has the beneficial effects as follows: there is good high-temperature stability, can be widely used in the hydraulic efficiency system close to the various equipment of thermal source, fire-prone such as ironmaking, steel-making, die casting, continuous casting, hot rolling, colliery, glasswork processing and excavator, also be applicable to the lower extremely frigid zones of envrionment temperature simultaneously, lubricity is good, and little to the infringement of oil pump and hydraulicvalve etc.
Embodiment
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The invention provides a kind of technical scheme: a kind of low temperature fire resistant hydraulic oil, it is characterized in that being made up of the quality proportioning of base oil 50-65%, epoxy soybean oil 18-28%, ethylenediamine tetraacetic acid (EDTA) 0.8-0.9%, corrosion prevention rust preventer 3-5%, sulfurized polyisobutylene 2-3%, tri 6-10%, benzotriazole 2-3%, tripoly phosphate sodium STPP 0.5-0.8%, di-iso-octyldiphenylamine 0.6-0.9% and polymethacrylate 0.2-0.3%.Described corrosion prevention rust preventer is made up of one or more in monoethanolamine, diethanolamine and trolamine and carboxylic acid reaction, has excellent anti-rust and corrosionproperties.
Low temperature fire resistant hydraulic oil of the present invention has good high-temperature stability, can be widely used in the hydraulic efficiency system close to the various equipment of thermal source, fire-prone such as ironmaking, steel-making, die casting, continuous casting, hot rolling, colliery, glasswork processing and excavator, also be applicable to the lower extremely frigid zones of envrionment temperature simultaneously, lubricity is good, and little to the infringement of oil pump and hydraulicvalve etc.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, therefore all changes be intended in the implication of the equivalency by dropping on claim and scope are included in the present invention, any Reference numeral in claim should be considered as the claim involved by limiting.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
