Abstract
The utility model discloses a novel graphite tape which comprises a base material layer, adhesive layers and a release material layer, wherein the adhesive layers are respectively arranged on two sides of the base material layer; the release material layer is arranged on the adhesive layers; a graphite film is arranged in the base material layer; an aluminum foil is plated on the base material layer; a parting line which can be used for tearing is arranged on the release material layer. According to the novel graphite tape, the graphite film is arranged in the base material layer, the aluminum foil is plated on the base material layer, the graphite has high reliability and high heat-conducting property, and heat accumulated by a heating electronic component can be timely and efficiently transferred to the aluminum foil and is taken out of the electronic component through the aluminum foil, so that the temperature of the electronic component is reduced. Meanwhile, the adhesive layers are made of low-acid glue and polyurethane foam powder, the low-acid glue does not contain acid radical and does not have corrosion on metals, and uniform heat dissipation of the tape is improved.
Description
Technical field
The utility model relates to sealing tape technical field, is specially a kind of novel graphite adhesive tape.
Background technology
Along with scientific and technical develop rapidly, electronic product (as notebook computer, mobile phone, panel computer etc.) becomes ultra-thin, light day by day, electronic product volume is more and more less, function from strength to strength, cause electronic component integration degree more and more higher, electronic component in use its inner meeting produces a large amount of heats, if distributed not in time, not only damage the performance of self, more easily reduce the Performance And Reliability of whole system.Mainly adopt at present the heat dissipation metals such as Copper Foil, aluminium foil, but due to resource-constrained, and expensive, radiating effect neither be very desirable, therefore use the thermally conductive material with excellent propertys such as high reliability, high thermal conductivity, it is hot standby that the heat efficiently heat-generating electronic elements being gathered in time passes to heat radiation, very important to solving electronic product radiating problem.
Utility model content
The technical problem that the utility model solves is to provide a kind of novel graphite adhesive tape, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A novel graphite adhesive tape, comprises substrate layer, glue paste layer and separated type material layer; Wherein, described substrate layer two sides is respectively arranged with glue paste layer, and described separated type material layer is arranged on glue paste layer, in described substrate layer, is provided with graphite film, on described substrate layer, be coated with aluminium foil, on described separated type material layer, cut off and be provided with the cut-off rule that can be used for tearing.
In the utility model, in described graphite film, be provided with abscess, can effectively reduce the heat conduction between graphite granule.
In the utility model, described glue paste layer is made by low sour glue and polyurethane foam powder, does not contain acid group in low sour glue, to metal non-corrosiveness, be conducive to improve adhesive tape Homogeneouslly-radiating, reduce its inner meeting in electronic component use procedure and produce a large amount of heats, in time distribute heat.
In the utility model, described separated type material layer is anti-electrostatic release film.
In the utility model, in described substrate layer, be provided with graphite film, on described substrate layer, be coated with aluminium foil, graphite has high reliability, high thermal conductivity, the heat that can efficiently heat-generating electronic elements be gathered in time passes to aluminium foil, aluminium foil is taken heat out of electronic component, thereby reduces the temperature of electronic component.
Beneficial effect: be provided with graphite film in the utility model in substrate layer, on substrate layer, be coated with aluminium foil, graphite has high reliability, high thermal conductivity, the heat that can efficiently heat-generating electronic elements be gathered in time passes to aluminium foil, aluminium foil is taken heat out of electronic component, thereby reduces the temperature of electronic component; Glue paste layer is made by low sour glue and polyurethane foam powder simultaneously, in low sour glue, not containing acid group, to metal non-corrosiveness, is conducive to improve adhesive tape Homogeneouslly-radiating.
