Abstract
The utility model discloses a graphite heat-dissipation sticking tape which comprises a PET (polyethylene terephthalate) substrate layer, wherein the lower surface of the PET substrate layer is plated with an aluminum foil layer; the lower surface of the aluminum foil layer is coated with an adhesive layer; the other surface of the adhesive layer is bonded with a release material layer; a plurality of graphite particles are uniformly distributed in the adhesive layer; a diameter range of each graphite particle is 3-6 micrometers; and the release material layer is a release film layer or a release paper layer. The heat-conducting property of the graphite heat-dissipation sticking tape in the length direction and the thickness direction is improved; the uniformity of the heat-conducting property of the sticking tape is achieved; the dissipation of heat is facilitated; local overheat of the sticking tape is avoided; the property of the graphite heat-dissipation sticking tape is improved; and the life of the graphite heat-dissipation sticking tape is prolonged.
Description
Technical field
The utility model relates to a kind of thermal paste adhesive tape, relates in particular to a kind of graphite radiating 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.
Summary of the invention
The utility model provides a kind of graphite radiating sealing tape, it has guaranteed that length and thickness direction have all improved thermal conductivity this graphite radiating sealing tape, and realized the homogeneity of adhesive tape heat conductivility, the adhesive tape local superheating is also avoided in the diffusion that both had been conducive to heat, has improved performance and the life-span of product.
For achieving the above object, the technical solution adopted in the utility model is: a kind of graphite radiating sealing tape, comprise a PET substrate layer, this PET substrate layer lower surface plating has aluminium foil layer, this aluminium foil 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 Ratio of described PET substrate layer and aluminium foil layer is 1:0.1 1.
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 utility model graphite radiating sealing tape, it has guaranteed that length and thickness direction have all improved thermal conductivity, and has realized the homogeneity of adhesive tape heat conductivility, the adhesive tape local superheating is also avoided in the diffusion that both had been conducive to heat, has improved performance and the life-span of product; 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.
