Description
Technical field
The present invention relates to the technical field of railway grease, relate in particular to a kind of extreme pressure bentonite-thickened grease.
Background technology
Railway grease is that a kind of grease-like with certain viscosity is semi-solid, is mainly modulated with viscosifying agent by MO (or ucon oil) to form, and its difference according to viscosifying agent can be divided into two types of soap grease and non-soap grease; Bentonite-thickened grease belongs to nonsoap grease, is to be processed by organobentonite multiviscosisty medium viscosity after surfactant treatment or HV Dormant oils, and it is widely used in the heavy duty equipment of industries such as mine, metallurgy, casting and steel rolling; And heavy-load automobile; Papermaking equipment, cement manufacture plant, high temp tunnel kiln car; The airplane wheel bearing, the lubricant housings of equipment such as railway diesel locomotive.
Bentonite-thickened grease is the same with other double composition grease all to be a type of high temperature resistant railway grease, and bentonite-thickened grease mainly contains following characteristics:
1) bentonite-thickened grease does not have dropping point, and its high warm nature only is decided by the resistance to elevated temperatures of tensio-active agent, and general bentonite-thickened grease can use more than 150 ℃.
2) low temperature properties of bentonite-thickened grease depends mainly on the low temperature properties of the base oil of selecting for use, also depends on the consumption of viscosifying agent simultaneously.
3) structured particles of bentonite-thickened grease is than the anti-shearing of soap fiber; But; Because wilkinite has passed through surfactant treatment, therefore, the mechanical stability of bentonite-thickened grease changes with the performance of different surface active agents; In rolling bearing, use for a long time, bentonite-thickened grease is easily thinning and flow out.
4) bentonite-thickened grease is bad to the non-corrosibility of metallic surface, must add effective rust-preventive agent and improve.
5) bentonite-thickened grease combines with base oil firmly owing to the wilkinite viscosifying agent; Show its good colloid stability on the one hand; Show base oil on the other hand and be difficult to the engaging friction surface, so resistance to abrasion and resistance to marring are not ideal, influence its use in high speed roller bearing.
Because the above performance of bentonite-thickened grease has obtained developing widely and using at present in industry.Yet existing bentonite-thickened grease also comes with some shortcomings in actual use; Not high enough like dropping point; Less stable, particularly extreme pressure and antiwear behavior promptly prevent or reduce the wearing and tearing of metallic surface under the moderate duty condition; Prevent that the metallic surface from taking place under high-load condition that sintering, card are stung, the performance aspect the scratch, and these performances of existing bentonite-thickened grease also difficult one reach request for utilization at present.
The present invention is exactly in order to improve the quality of bentonite-thickened grease, to have the good characteristic that has both high temperature and extreme-pressure anti-wear preferably, promptly can satisfy special lubricant housings, can prolonging the work-ing life of equipment again.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of high-quality bentonite-thickened grease is provided, it has high dropping point and good mechanical stability, and consistency change is few under high-temperature condition, can keep the bentonite-thickened grease of high extreme pressure property again.
For realizing above-mentioned purpose, the present invention proposes following technical scheme: a kind of high temperature extreme pressure bentonite-thickened grease, and it comprises following composition (in weight part):
Base oil: 80～95%;
Viscosifying agent: 3～20%;
Extreme-pressure additive: 5～20%;
Active dispersion agent: 10～30%.
Wherein, 100 ℃ of viscosity of described base oil are 10～50mm2/s, are made up of the mixture of a kind of of MO, synthetic oil or two kinds.
Said base oil by gather-mixtures a kind of or two kinds such as a alkene, two types or three types of mineral base oils, polyol ester form.
Described viscosifying agent is the organobentonite of handling through the organic amine surface coverage.
Described extreme-pressure additive is a solid lubricant.
Described solid lubricant is a kind of or compositions of the mixture more than two kinds such as oildag, tungsten disulfide, talcum powder, molybdenumdisulphide, mica powder, nano-calcium carbonate and cyanogen urea acid trimeric cyanamide.
Described active dispersion agent is to be selected from a kind of in acetone, the propylene carbonate.
The preparation method of high temperature extreme pressure bentonite-thickened grease of the present invention is: at first base oil and extreme-pressure additive are fully mixed earlier; Add viscosifying agent again; Continue fully to mix; Add active dispersion agent then, mix the regular hour, grinding at last is uniformly dispersed and makes high temperature extreme pressure bentonite-thickened grease of the present invention.
Compared with prior art; The high temperature extreme pressure bentonite-thickened grease that the present invention discloses has the good high-temperature performance; Mechanical stability; Be particularly suitable for the power lubrication position of working under high temperature, heavy loading, the high pollution operating mode, can either satisfy the lubricated of special lubricant housings such as steel rider slideway, ore deposit forklift bearing, automobile-used chassis, water pump, cementing truck lubricant housings and bearing etc., can prolong the work-ing life of equipment again.
