Abstract
The utility model discloses insulation and heat-conducting foil which comprises a metal layer and a ceramic layer, wherein the ceramic layer is arranged on the surface of the metal layer through vacuum plating; the metal layer is a copper sheet, an aluminum sheet, a nickel sheet, a tin sheet, a zinc sheet, a silver sheet or a titanium sheet; and the ceramic layer is a heat-conducting ceramic body and is 0.05-5 micrometers in thickness. Since ceramic is insulated, and metal has good heat conductivity, the foil can have insulation and high heat-conducting properties after the surface of the metal is covered with the ceramic.
Description
Technical field
The utility model relates to a kind of insulating heat-conductive paper tinsel, belongs to the insulating heat-conduction material technical field.
Background technology
In the heat conduction, the heat transfer efficiency of metal is than higher, but metal can conduct electricity, in some scenarios, need insulate, and macromolecular material for example silica gel, resin etc. are the good insulation performance materials, but its heat transfer efficiency is too low, can not satisfy the function of insulation and high heat conduction simultaneously.
Summary of the invention
The utility model proposes a kind of insulating heat-conductive paper tinsel, in order to a kind of insulation and the high composite of heat transfer efficiency to be provided.
For realizing this purpose, the method that the utility model adopts is: a kind of insulating heat-conductive paper tinsel, comprise metal level and ceramic layer, and layer on surface of metal is provided with ceramic layer by the vacuum plating.
Described metal level is copper sheet or aluminium flake or nickel sheet or tin sheet or zinc metal sheet or silver strip or titanium sheet.
What described ceramic layer adopted is the thermal conductive ceramic body.
Described metal layer thickness is 0.005mm-0.25mm.
Described ceramic layer thickness is 0.05 μ m-5 μ m.
Its beneficial effect is: because ceramic insulation, and metal has good thermal conductivity, after the metal surface is coated with pottery, just can have insulation and high thermal conductivity simultaneously.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the utility model structural representation.
The specific embodiment
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.For realizing the purpose of insulation and high thermal conductivity, the utility model proposes a kind of insulating heat-conductive paper tinsel, as shown in Figure 1, comprise metal level 1 and ceramic layer 2, ceramic layer 2 electroplates by physical vacuum or chemical vacuum is electroplated the surface that is attached to metal level 1, the thickness of metal level 1 is 0.005mm-0.25mm, and the metal that adopts is copper sheet or aluminium flake or nickel sheet or tin sheet or zinc metal sheet or silver strip or titanium sheet, and metal level 1 makes material have good heat-conducting.What described ceramic layer 2 adopted is the thermal conductive ceramic body, and raw material comprises aluminium oxide, aluminium nitride, boron nitride, beryllium nitride or beryllium oxide, and ceramic layer 2 thickness are 0.05 μ m-5 μ m, and ceramic layer 2 makes material have insulating properties.The utility model is not limited to the aforesaid specific embodiment.The utility model expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
