Abstract
The utility model discloses an ultrathin graphite heat conducting adhesive tape, which comprises an ultrathin PET (polyethylene terephthalate) substrate layer, wherein the lower surface of the ultrathin PET substrate layer is coated with a viscose layer; the other surface of the viscose layer is coated with a mold release material layer; a plurality of graphite particles are distributed uniformly inside the viscose layer; and the diameter of the graphite particles is 3-6 micrometers, and the thickness of the ultrathin PET substrate layer is 0.004-0.012 millimeters. The ultrathin graphite heat conducting adhesive tape can prevent scratches on the surface of a graphite heat exchange material effectively, so that a heat conducting interface material which can be used stably and has good heat conductivity is obtained; and the adhesive tape can be used conveniently, and the surface of a heat source can be combined with the heat conducting adhesive tape closely.
Description
Technical field
The utility model relates to a kind of thermal paste adhesive tape, relates in particular to a kind of ultra-thin graphite heat conducting sealing tape.
Background technology
Along with the fast development of electron trade, now from common desktop computer, to notebook computer, panel computer, smart mobile phone, scientific and technical innovation is advanced by leaps and bounds.Electronic product carries more and more lighting, and volume is more and more less, and function causes integrated level more and more higher from strength to strength like this.Cause like this volume dwindling, the function grow is large, directly causes the heat radiation of electronic devices and components to require more and more higher.And the fan type radiating that adopted in the past because volume is large, can produce the problems such as noise, is eliminated by market gradually.And then produced other heat sink material, as Copper Foil, the heat radiation of aluminium foil class, but due to resource-constrained, and expensive, radiating effect is good in the imagination not also, slowly, all seeking new efficient heat sink material.Scientific discovery, the distinctive heat radiator performance of graphite material can satisfy the heat radiation of existing electronic devices and components well.
And in the market graphite paper heat radiation be many, but also there are some shortcomings in this, the processing more complicated will be passed through special processing, and thickness relatively thick (graphite material thickness is thicker, and radiating effect is poorer).
Summary of the invention
The utility model provides a kind of ultra-thin graphite heat conducting sealing tape, and this ultra-thin graphite heat conducting sealing tape can prevent graphite thermal exchange material surface tear effectively, thereby obtains heat-conducting interface material a kind of stable use, that have thermal conductive resin; And easy to use, be convenient to be combined closely in thermal source surface and heat-conducting glue adhesive tape.
For achieving the above object, the technical solution adopted in the utility model is: a kind of ultra-thin graphite heat conducting sealing tape, comprise a ultra-thin PET substrate layer, this ultra-thin PET substrate layer lower surface is coated with adhesive-layer, another surface label of this adhesive-layer is covered with the separated type material layer, and described adhesive-layer inside is evenly distributed with several graphite granules.
In technique scheme, further improved technical scheme is as follows:
1. in such scheme, the diameter range of described graphite granule is 36 microns.
2. in such scheme, the thickness of described ultra-thin PET substrate layer is 0.004 0.012mm.
3. in such scheme, described separated type material layer is release film layer or off-style paper layer.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The ultra-thin graphite heat conducting sealing tape of the utility model, its ultra-thin PET substrate layer has played the surface insulation effect on the one hand, separately can effectively prevent graphite thermal exchange material surface tear, thereby obtain heat-conducting interface material a kind of stable use, that have thermal conductive resin; Secondly, its adhesive-layer inside is evenly distributed with several graphite granules, and is easy to use, after only needing the separate-type paper on surface is peeled off, covers respectively thermal source surface and radiating subassembly, can be combined closely with the heat-conducting glue adhesive tape in thermal source (electron device) surface.
