Description
Technical field
The present invention relates to lubriation material technical field, and in particular to a kind of white ultra high temperature lubricating grease and preparation method thereof.
Background technology
Lubricating grease is compared with excellent stability with existing oil lubrication as a kind of conventional lubricant medium, resisted
The features such as oxidisability, mechanical stability, adhesiveness, extreme-pressure wear-resistant and sealing, it is suitably applied and lubricant medium is moved
Precision, bearing capacity, extreme pressure property, the lubricant housings of rotating speed and the longer plant equipment of service life.With industrial modern
That changes continues to develop use requirement more and more higher of the portion requiring lubrication such as plant equipment for lubricating grease, the use to lubricating grease
Heat resistance is also to propose higher requirement.Existing Hmp grease exist mostly softening under the high temperature conditions, point oil,
It is dry and cracked, fusing, volatilization, hardening etc. behavior cause lubricating grease lose lubricant effect cause plant equipment occur abrasion, sintering, it is seizing
Deng so as to causing plant equipment can not work, largely repair, reduce the behavior such as service life.Therefore produce a kind of resistance to superelevation
The grease product of warm nature matter has very big demand space for mechanical processing industry.
The content of the invention
The present invention for the problem of lubricating grease is present in the prior art and it is not enough provide it is a kind of have superelevation heat resistance,
Regardless of it is oily, not dry and cracked, antioxygenic property is excellent, the white ultra high temperature lubricating grease that has good stability.The lubricating grease is using a kind of high
Viscosity silicone oil is to replace the tackifier used in existing lubricating grease to make up high-viscosity polymer in 300 DEG C of high temperature above conditions
The coking dry and crack problemses of lower presence.It can be made using viscous silicone fluid in the case where improving viscosity, preventing point oil by high temperature
There can be good associativity so that prepared lubricating grease has more preferable heat-resisting quantity, lubrication with silica
Property, the performance such as anti-point of oil, anti-chap.
In order to reach above-mentioned purpose, one aspect of the present invention is achieved through the following technical solutions：A kind of white superhigh temperature lubrication
Fat, it is characterised in that on the basis of lubricating grease quality, it is made up of the raw material of following mass fraction：50%-80% basis
Oil, 5%-30% thickening agent, 5%-15% viscous silicone fluid, 1%-3% structural stabilizing agent, 5%-15% lubrication
Agent.
One or more mixtures of the base oil of the present invention in silicone oil, artificial oil, synthesizing ester oil, it is excellent
Elect phenyl silicone oil as.
Thickening agent of the present invention is one or more in silica, boron nitride, graphite, polytetrafluoroethylene (PTFE)
Mixture, preferably silica.
Viscous silicone fluid of the present invention is selected from high viscosity methyl-silicone oil, high viscosity phenyl silicone oil, high viscosity ethyl silicon
Oil etc., preferably high viscosity methyl-silicone oil.
Structural stabilizing agent of the present invention is Diphenylsilanediol.
Lubricant of the present invention is selected from the mixture of one or both of boron nitride, polytetrafluoroethylene (PTFE).
Second aspect of the present invention provides a kind of preparation method of above-mentioned white ultra high temperature lubricating grease, and it comprises the following steps：
(1) base oil, thickening agent are added and 120 DEG C -150 DEG C, reaction is stirred uniformly and be warming up in reactor
30min-60min；
(2) structural stabilizing agent, lubricant, high viscosity methyl-silicone oil are added in a kettle. and are stirred 60-120min
Homogenizing reaction；
(3) reactant obtained above cooled, filtered, grinding the white superhigh temperature lubrication that can obtain the present invention
Fat.
Its outstanding feature of a kind of ultra high temperature lubricating grease of the present invention is using viscous silicone fluid come instead of existing height
The tackifier added in temperature lubricating grease preparation process.Due to the tackifier in existing Hmp grease be mostly high polymer its
The coking of grease product, dry and cracked and point oily phenomenon generation can be caused under hot conditions more than 300 DEG C；So this hair
It is bright preferably to be combined a kind of prepared white superhigh temperature by adding high viscosity methyl-silicone oil and silica thickening agent
Lubricating grease can tolerate 300 DEG C of high temperature above, excellent inoxidizability, structure stability, lubricity, chemical stability, the production of preparation
Product without obvious dropping point, under the high temperature conditions no cracking, point oil, hardening etc. phenomenon.
