Description
Technical field
The utility model relates to a kind of high tenacity adhesive tape, belongs to adhesive material technical field.
Background technology
Electronic product carries more and more lighting, and volume is more and more less, and function from strength to strength, causes integrated level more and more higher like this.Cause like this volume dwindling, function grow is large, directly causes the heat radiation of electronic devices and components to require more and more higher.On the one hand, the fan type radiating adopting in the past, because volume is large, can produce the problems such as noise, is eliminated gradually by market.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 finding new efficient heat sink material.On the other hand, graphite material has property widely, comprise heigh clarity, high conductivity, high thermal conductivity, high strength etc., utilize graphite material, can develop various product application types, such as graphite circuit structure, graphite core chip architecture, graphite touch screen structure, etc.Although there are various application possibilities, be directed to graphite material, how it is effectively processed, such as clean cut, be still the problem that needs solution.
But graphite flake also has weak point, though be that high conductive graphite sheet has certain folding resistance, but the weak strength between material, can be torn easily, or because of the displacement of institute's adhesive attachment means, disrepair phenomenon occur, entry material comes off etc., thereby cause the short circuit of circuit, again, in cutting graphite flake process, there will be the technical problems such as graphite flake breaks.
Summary of the invention
The utility model object is to provide a kind of high tenacity adhesive tape, and this high tenacity adhesive tape can prevent that the Graphite Powder 99 of graphite linings and graphite granule from coming off, thereby avoids short circuit and the electrical impact on wiring board, has improved the reliability of product.
For achieving the above object, the kind technical scheme that the utility model adopts is: a kind of high tenacity adhesive tape, comprise a graphite linings, and this graphite linings upper surface is all covered with complex metal layer, this complex metal layer by aluminium lamination and copper layer by layer stacked group become, described copper layer is between aluminium lamination and graphite linings; One off-style paper layer surface is covered with heat-conducting glue adhesion coating and bonding with graphite linings lower surface, the laminated polyester film that a lower surface is coated with adhesive layer is covered on complex metal layer upper surface, this laminated polyester film length and width are all greater than length and the width of graphite linings, one off-style paper layer is covered on another surface of heat-conducting glue adhesion coating, the length of this off-style paper layer and width are greater than respectively length and the width of graphite linings, and laminated polyester film length and width size equates with off-style paper layer length and width size.
In technique scheme, further improved plan is as follows:
1. in such scheme, the length of described laminated polyester film and width all exceed 1 ~ 2mm than the length of graphite linings and width.
2. in such scheme, described composition metal layer thickness is 40 ~ 80 μ m, and copper layer is 10:4 ~ 6 with aluminum layer thickness ratio.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
The utility model high tenacity adhesive tape, its laminated polyester film length and width are all greater than length and the width of graphite linings, one off-style paper layer is covered on another surface of heat-conducting glue adhesion coating, the length of this off-style paper layer and width are greater than respectively length and the width of graphite linings, and laminated polyester film length and width size equates with off-style paper layer length and width size, Graphite Powder 99 and the graphite granule that can prevent graphite linings come off, thereby avoid short circuit and the electrical impact on wiring board, have improved the reliability of product; Secondly, adopt by aluminium lamination and copper layer by layer stacked group become complex metal layer, be conducive to form the thermograde of ladder, thereby maintain heat conducting impellent, be conducive to that heat is stable to be transmitted fast.
