Description

A kind of electrically conductive type ultra high temperature lubricating grease and preparation method thereof
Technical field
The present invention relates to lubriation material technical field, and in particular to a kind of electrically conductive type ultra high temperature lubricating grease and its preparation side Method.
Background technology
Electrically conductive type lubricating grease is seen as each position that a kind of new electrical material is widely used in electrical device And certain conduction, drag reduction, anti-corrosion and other effects can be reached on the place of the connecing face of each Power tabs.
Ultra high temperature lubricating grease is a kind of resistance to hot conditions stability inferior, oxidation stability, mechanical stability, extreme pressure mill The higher lubriation material of requirement such as property, adhesiveness, lubricity.Continuous development plant equipment with the modernization of industry etc. needs to moisten Sliding position uses heat resistance and the electric conductivity of privileged sites for the requirement more and more higher of lubricating grease to lubricating grease Higher requirement can be proposed.Softening under the high temperature conditions, point oily, dry and cracked, molten mostly be present in existing ultra high temperature lubricating grease The behaviors such as change, volatilization, hardening, conductive capability deficiency cause lubricating grease lose lubrication or conduction, drag reduction, save and other effects cause machine Tool equipment occurs abrasion, sinters, be seizing, can not work, largely repair, and reduces the use longevity of plant equipment and privileged sites Life etc..Therefore a kind of electrically conductive type ultra high temperature lubricating grease product is produced for industries such as machining, electrical equipment, office instruments For there is very big demand space.
The content of the invention
The present invention is for problem and shortage existing for lubricating grease in the prior art, there is provided a kind of electrically conductive type superelevation is gentle Consistent lubricant, mechanical stability is good under the high temperature conditions, antioxygenic property is excellent and production phenomena such as without point oily, dry and cracked, coking It is raw.The characteristics of protrusion of the lubricating grease be use a kind of viscous silicone fluid substitute the tackifier used in existing lubricating grease with Make up high-viscosity polymer existing coking, dry and crack problemses under the conditions of 300 DEG C of high temperature above.Can be using viscous silicone fluid Improve viscosity, prevent point oil in the case of can be with good associativity so that made by high temperature action and silica Standby lubricating grease has more preferable heat-resisting quantity, lubricity, resists a point oil, anti-chap, without performances such as hardening.
In order to reach above-mentioned purpose, one aspect of the present invention is achieved through the following technical solutions：
A kind of electrically conductive type ultra high temperature lubricating grease, it is characterised in that following quality point is included on the basis of lubricating grease quality Several raw material compositions：Base oil 20%-75%；Thickening agent 5%-30%；Viscous silicone fluid 5%-35%；Conductive agent；5%- 20%；Lubricant 5%-17%；Antioxidant 1%-3%.
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.
The one kind of conductive agent of the present invention in electrically conductive polyaniline, conductive metal powder, conducting metal oxide Or a variety of mixtures, preferably electrically conductive polyaniline.
Antioxidant of the present invention is selected from Diphenylsilanediol.
One or more mixing of the lubricant of the present invention in boron nitride, polytetrafluoroethylene (PTFE), silica gel, graphite Thing.
Second aspect of the present invention provides the preparation method of above-mentioned electrically conductive type ultra high temperature lubricating grease, and it comprises the following steps：
(1) take base oil add normal-pressure reaction kettle in and start to warm up while stirring add thickening agent and be warming up to 120 DEG C- 150 DEG C or so, the reaction time is 30min-120min or so.
(2) continue heat up stirring reaction to 180 DEG C -200 DEG C or so start simultaneously at addition viscous silicone fluid, antioxygen Agent, lubricant, conductive agent, stirring reaction 60min-120min or so, finally it is cooled to 90 DEG C -120 DEG C or so；
(3) mixture obtained above is cooled down, homogeneous/grinding, filtering can obtain a kind of electrically conductive type superelevation Temperature lubricating grease.
A kind of electrically conductive type ultra high temperature lubricating grease of the present invention, its outstanding feature are using viscous silicone fluid come instead of existing There are the tackifier added in ultra high temperature lubricating grease preparation process.Because the tackifier in existing ultra high temperature lubricating grease are mostly The coking of grease product, dry and cracked and point oily phenomenon generation can be caused under its hot conditions more than 300 DEG C of high polymer； So the present invention is by adding high viscosity methyl-silicone oil, preferably the prepared one kind of combination can with the progress of silica thickening agent Conductivity type ultra high temperature lubricating grease can tolerate 300 degree of high temperature above, have excellent inoxidizability, structure stability, lubricity, chemistry Stability, electric conductivity etc..Superhigh temperature conductive grease prepared by the present invention without obvious dropping point, tortoise does not occur under the high temperature conditions Split, divide phenomena such as oil, hardening.
