Description
Technical field
The present invention relates to silicone grease field, more particularly to a kind of high-temperature resistant nano silver heat-conducting silicone grease.
Background technology
Heat-conducting silicone grease is a kind of common Heat Conduction Material, one kind of thermal interfacial material, can life-time service is also more than 200
Cream fat can be kept original-pack, and with good chemical stability, it is nontoxic, tasteless that corrosion is not resulted in base material.Heat-conducting silicone grease
The air gap between radiating contact surface can also be effectively eliminated, the heat of device can be dispersed.Additionally, having operation construction
Simply, later stage cleaning is easy and is easy to the advantage of plant maintenance.
Heat-conducting silicone grease be with silicone oil based on, conduction powder as filler and add function additive, then blended grinding plus
The product that work is prepared from.Wherein, what the base oil for heat-conducting silicone grease was commonly used has methyl phenyl silicone oil, methyl-silicone oil, fluorine chlorine
Hydrocarbon modified silicon oil or long-chain alkyl-silicone oil etc.；The heat conductivility of heat-conducting silicone grease can be improved by adding filler.Heat filling
Style be：Metal class, carbons or ceramic-like materials.
Now with the more and more higher of electricity needs in people's life, for transmission line capability there has also been higher requirement, because
This needs more stable power transmission and transformation line of more, function.Power transmission and transformation line can be still faced in running several asks greatly
Topic：The electric energy of conveying can produce substantial amounts of heat, need to shed in time；Circuit is exposed to be easily corroded out of doors, need to carry out anti-
Shield.Generally use currently for these problems and smear Hmp grease to solve, but most Hmp grease radiating effect
It is really poor, it is impossible to timely by the heat dissipation in circuit.The heat-conducting effect of heat-conducting silicone grease preferably, but is applied to defeated change
Remain a need for being improved its heat-resisting effect and sealing protected effect in electric line.
The content of the invention
It is an object of the invention to provide a kind of high-temperature resistant nano silver heat-conducting silicone grease, the heat-conducting silicone grease temperature tolerance is strong, higher
Temperature conditionss under can still keep stable.And heat-conducting effect is good, can the thermal conductivity on effectively faster devices surface go out.
For achieving the above object, the present invention is employed the following technical solutions：
A kind of high-temperature resistant nano silver heat-conducting silicone grease, in terms of parts by weight, including following components：
Silicone oil 20-35 parts, aluminium nitride 42-63 parts, aluminium oxide 18-27 parts, nano-silver thread 4-7 parts, iron octoate 1-3 parts, powder
Coal ash 4-16 parts, dispersant 15-27 parts.
Preferably, the silicone oil is one or more in methyl-silicone oil, fluorochlorohydrocarbon modified silicon oil or methyl phenyl silicone oil
Mixture.
Preferably, the mass ratio that feeds intake of the aluminium nitride and aluminium oxide is 7:3.
Preferably, the aluminium nitride is a kind of pale powder, and density is 3.2g/cm3；Particle mean size is 1-5 μm.
Preferably, the aluminium oxide is a kind of white powder, and density is 3.9g/cm3；Particle mean size is 1-5 μm.
Preferably, the nano-silver thread is a kind of pale powder, and density is 10.5g/cm3；Particle mean size is 1-5 μm.
Preferably, the dispersant is one or more in liquid paraffin, ethylene glycol or Tissuemat E.
The high-temperature resistant nano silver heat-conducting silicone grease, it is adaptable to the radiating and sealing of power transmission and transformation line.
The invention has the advantages that, using heat-conducting silicone grease using in power transmission and transformation line, effectively can increase
Heat conduction and anticorrosion effect in circuit, is conducive to extending the service life of power transmission and transformation line.The heat-conducting silicone grease uses aluminium nitride
Mix as filler in certain proportion with aluminium oxide, use cooperatively, have heat conductivity compared to any of which is used alone
The effect that can be improved.Coordinated using a small amount of nano-silver thread and flyash, be aluminum nitride-alumina compound cooperative cooperating,
So that the heat-conducting silicone grease has good heat conductivility.The heat-conducting silicone grease can keep cream under higher temperature conditionss simultaneously
Shape, sealing are good.
