The invention further specifically discloses the preparation method of the low-temperature torque conductive lubricating grease. The lubricating grease disclosed by the invention is special lubricating grease which can normally work under an extremely low-temperature condition and can be specially used on electrical appliances and electric tools in rapid cooling areas such as northeast China, Russia, the South Pole and the North Pole.

Description

Low temperature torque conductive grease and preparation method thereof
Technical field
The invention belongs to special grease technical field, and in particular to a kind of low temperature torque conductive grease and its preparation side Method.
Background technology
Electrical equipment friction pair, power switch, receptacle, instrument and plant equipment need the electricity such as the conducting position of protection The electronic devices and components of aspect, they are all high-grade and the electronic devices and components of precision, some moving parts of these electronic devices and components Do not require nothing more than dust-proof, moistureproof, anti-oxidant, anticorrosive, lubrication and also require conduction, lubrication is to ensure the use of electronic devices and components Life-span, conduction is need of work.Conductive grease substitutes Boring process of tin and silver plating process, reduces production cost, maintenance side Just the rotor and carbon brush for example above motor, rotor could be rotated after energization, and it is fortune at a high speed with the contact surface of carbon brush Dynamic, if do not lubricated, the friction pair between carbon brush and rotor can wear and tear quickly, and time length can be produced because of loose contact Generator is overheated, reduces the service life of motor.Ensureing the service life of motor will use lubricating grease at the position of motion, In order to ensure that normal work will ensure that lubricating grease has good conductance.The electronic devices and components of many slips in order to ensure friction Secondary service life should all use conductive grease.
As common lubricant fat, will be hardened general conductive grease caking under conditions of extremely trembling with fear, and so lubricate Fat just loses defencive function.The present invention have developed a kind of conductive grease for using at low temperature, specially where cold Use, it is ensured that electrical equipment, machinery, motor etc. are normally used at low temperature.
The content of the invention
Present invention solves the technical problem that there is provided a kind of low temperature torque conductive grease and preparation method thereof, the method Obtained lubricating grease be it is a kind of under extremely low temperature use in the special of the position such as electrical equipment or electron gas components and parts friction pair Lubricating grease, extends the service life of these electrical equipments and electronic devices and components, while ensure that the normal of these electrical equipments Work.
The present invention adopts the following technical scheme that low temperature torque conductive grease, its feature exists to solve above-mentioned technical problem Then it is prepared from by the raw material of following weight percent proportioning：Base oil 55%-80%, thickening agent 13%-38%, additive 3%- 5% and conductive materials 5%-10%, wherein base oil is 45#Transformer oil or Alpha-olefin oil, thickening agent is aliphatic acid lithium salts, is added Agent is one or more in preservative, antioxidant or pour-point depressant, and preservative is sulphur, phosphorus, the organic compound of zinc, anti-oxidant Agent is organic amine compound, and pour-point depressant is T803, and conductive materials are metal powder or carbon black powder.
The preparation method of low temperature torque conductive grease of the present invention, it is characterised in that concretely comprise the following steps：
（1）By the 45 of 50 weight portions#Transformer oil is added in saponification kettle, and agitating heating is warming up to 80 DEG C of 26.9 weight portions of addition Ten dihydroxystearic acids, persistently stirring and be warming up to 90 DEG C is completely dissolved ten dihydroxystearic acids, stop heating saponification kettle Interior temperature continues to rise, and lithium hydroxide solution is added in saponification kettle when being naturally cooling to 90 DEG C, the lithium hydroxide solution It is that the lithium hydroxide of 4.2 weight portions is added in the water of 13 weight portions to be prepared；
（2）Continue the dehydration that heats up, the 45 of 5.7 weight portions are added when the temperature in saponification kettle reaches 160 DEG C#Transformer oil, soap Change and stop heating up when temperature in the kettle rises to 180 DEG C, circulation temperature lowering, shearing, add when temperature is down to 100 DEG C 1 weight portion sulphur, The T803 of phosphorus, the organic compound of zinc, the organic amine compound of 1 weight portion and 2 weight portions, is eventually adding the carbon of 8 weight portions Black powder, shearing degassing is obtained low temperature torque conductive grease.
The present invention is ensured by the use of carbon black powder as conductive material by the low temperature flow of transformer oil and Alpha-olefin oil The cryogenic property of lubricating grease, metal lithium soap is excellent lubricating grease carrier, and the obtained lubricating grease of the present invention is one kind in extremely low temperature Still can be with the special grease of normal work under the conditions of degree, can be specially anxious in China northeast, Russia, south and north poles etc. Use on the electrical equipment of cryogenic region, electric tool.
Specific embodiment
The above of the present invention is described in further details by the following examples, but this should not be interpreted as this The scope for inventing above-mentioned theme is only limitted to below example, and all technologies realized based on the above of the present invention belong to this Bright scope.
Embodiment
1st, by 50 kilogram 45#Transformer oil is added in saponification kettle, and agitating heating is warming up to 80 DEG C and adds 26.9 kilogram ten Dihydroxystearic acid, persistently stirring and be warming up to 90 DEG C is completely dissolved ten dihydroxystearic acids, stops heating saponification kettle interior temperature Degree continue rise, lithium hydroxide solution is added in saponification kettle when being naturally cooling to 90 DEG C, the lithium hydroxide solution be by 4.2 kilograms of lithium hydroxides are added to what is be prepared in 13 kg of water；
2nd, continue the dehydration that heats up, 5.7 kilogram 45 is added when the temperature in saponification kettle reaches 160 DEG C#Transformer oil, in saponification kettle Stop heating up when temperature rises to 180 DEG C, circulation temperature lowering, shearing adds 1 kilogram of sulphur, phosphorus, zinc to have when temperature is down to 100 DEG C Machine compound, 1 kilogram of organic amine compound and 2 kilograms of T803, are eventually adding 8 kilograms of carbon black powders, and shearing degassing is obtained low temperature Torque conductive grease.
Low temperature torque conductive grease obtained in the present embodiment is a kind of special grease, with Low ESR, good low Temperature lubricating grease performance and excellent electric conductivity are (such as conductive sliding dedicated for making electrical contact with sliding friction position under cryogenic conditions Ring), the contact of power switch, electrical connector, the conducting position of instrument and plant equipment, the lubricating grease is except electric action Dust-proof, moistureproof, anti-oxidant, anticorrosive and lubrication is also acted as in addition, and precision instrumentation, switch, moving component are played Protective effect and the effect for increasing the service life, but general conductive grease can solidify at cold temperature, very great Cheng The performance of lubricating grease is reduced on degree, lubricating grease obtained in the present embodiment is the conductive grease used under the conditions of extremely trembling with fear.
