Abstract
The invention discloses a high-temperature lubricating grease which comprises the following components in percentage by mass: 20-60% of base oil, 1-5% of a thickening agent, 1-5% of an antioxidant, 10-30% of organic sulfide and 5-10% of an anti-wear agent. The high-temperature lubricating grease is simple and easy in formula and relatively strong in practicability, has relatively good anti-rust, wear-resistant and high-temperature-resistant functions, and reduces the damage ratio of a machine.
Description
Technical field
The present invention relates to lubrication technical field, be specifically related to a kind of high temperature grease.
Background technology
Lubricating grease English name: lubricating grease; The grease-like of grease stiff is semi-solid.For the friction portion of machinery, play lubrication and sealing function.Also for metallic surface, rise and fill space and rust inhibition.Form primarily of mineral oil (or ucon oil) and viscosifying agent modulation.
Soap grease and non-soap grease two class can be divided into according to viscosifying agent.The metallic soaps such as lithium, sodium, calcium, aluminium, zinc commonly used by the viscosifying agent of soap grease, also use the metallic soaps such as potassium, barium, lead, manganese.The viscosifying agent graphite of non-soap grease, carbon black, asbestos also have (as polyurea based, the wilkinite) of synthesis, universal(lubricating)grease and special grease two kinds can be divided into according to purposes, the former is for common mechanical part, and the latter is used for tractor, railway locomotive, ship machinery, oil drilling machine, valve etc.Primary quality measure is dropping point, penetration degree, ash content and moisture etc.The index being used for evaluating lubricating grease colloidal stability is bleeding test, rolling bearing performance test etc.Tumbler test is the test method of consistency change under test roll extrusion effect.Fluidity test evaluates the test method of lubricating grease aid pumpability at low temperatures.Anti-water drenching test evaluates lubricating grease to the test method of the resistivity that water wash goes out.Colloid stability is that lubricating grease keeps colloid-stabilised, the performance that liquid Dormant oils is not separated out from fat in storage with in using.Mechanical stability represents that lubricating grease resists the performance of consistency change under machine work condition.Spot contact bearing torsional moment test is a kind of test method evaluating lubricating grease low-temperature performance.Lubricating grease viscosifying agent is scattered in a kind of stable solid or semi-solid product that form in liquid lubricant, wherein can add the additive and filler that are intended to improve certain characteristic of lubricating grease.Lubricating grease can be attached to vertical surface at normal temperatures and not run off, and can open wide or the friction position work of poor sealing, has that other lubricant institute is irreplaceable holds a little.Generally speaking, the lubricating grease consistency of identical soap base is better.Organic clay base is incompatible with other bases.Therefore, the many positions on automobile and engineering machinery all use lubricating grease as lubricant, i.e. our butter of often saying.
The effect of lubricating grease is mainly lubricated, protects and is sealed.
Most lubricating grease is used for lubrication, is called anti-friction grease.Anti-friction grease mainly plays reduction mechanical friction, prevents the effect of mechanical wear. and also held concurrently prevents the provide protection of metallic corrosion simultaneously, and sealing and dustproof effect.There are some lubricating grease to be mainly used to prevent metal rusting or corrosion, are called protection lubricating grease.Such as industrial vaselines etc. have minority lubricating grease specially to do sealing, are called packing grease, such as thread compound.Lubricating grease is the material of semi-solid mostly, has unique mobility.
The principle of work of lubricating grease is that oil remains on the position of needs lubrication by viscosifying agent, and when having load, oil discharges by viscosifying agent, thus plays lubrication.
When normal temperature and stationary state, it resembles solid, can keep the shape of oneself and not flow, can stick to not landing on metal.At high temperature or when being subject to the external force exceeding certain limit, it resembles again liquid can produce flowing.When lubricating grease is subject to the shearing action of moving parts in machinery, it can produce flows and lubricates, and lowers the friction and wear between moving surface.After shearing action stops, it can recover certain denseness again, this special mobility of lubricating grease, determines that it can lubricate being unsuitable for the position with lubricating oil.In addition, because it is semi-solid material, its sealing function and provide protection are all good than lubricating oil.
Machine life-time service can produce heat, and lubricating grease its lubricating grease extreme pressure property under hot operation can significantly decline, thus affects the life-span of equipment, increases cost.
Summary of the invention
The object of this invention is to provide a kind of high temperature grease, its formula is simple and easy, and practicality is comparatively strong, has good antirust wear-resistant high temperature resistant function, reduces the damage rate of machine.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: its mass ratio is: base oil 20%-60%, viscosifying agent 1%-5%, antioxidant 1%-5%, organic sulfide 10%-30%, anti-wear agent 5%-10%.
Described base oil is mineral oil or synthetic oil one wherein or both mixing, preferred mineral oil.
Described viscosifying agent be acid amides, polyureas or fluorine carbon wherein one or several, preferred polyureas.
Described antioxidant be two dodecyl selenium, L57 wherein one or several, preferably two dodecyl selenium mixes with L57.
Described anti-wear agent is three (2-chloroethyl) phosphorous acid ester, the one of trifluorochloroethylene telomer or both mixing, preferred trifluorochloroethylene telomer.
Described organic sulfide is wherein a kind of or both mixing of benzyl disulfide, sulfurized olefin cotton oil, preferred benzyl disulfide.
The present invention has following beneficial effect: its formula is simple and easy, and practicality is comparatively strong, has good antirust wear-resistant high temperature resistant function, reduces the damage rate of machine.
