Technical field
The utility model relates to a kind of graphite heat conducting heat radiation adhesive tape, belongs to adhesive material technical field.
Background technology
Along with the acceleration of the continuous upgrading of electronic product, high integrated and high-performance electric subset growing, work package volume size is more and more less, and speed and the efficiency of work are more and more higher, and thermal value is increasing.Metal current class heat conduction and heat radiation assembly has been subject to restriction (the quality weight of its material and self heat conduction limit, radiating effect is low), must guarantee with the heat sink material of heat conduction and heat radiation technique and excellent performance effective work of electronic product, graphite heat conducting heat sink material is the preferred material that solves heat conduction and heat radiation.Because graphite itself is frangible, and and electronic product module when heat radiation assembling, need to be fixed it, by it together with the parts bonding that needs dispel the heat.
Summary of the invention
The utility model object is to provide a kind of graphite heat conducting heat radiation adhesive tape, adhesive tape local superheating is also avoided in the existing diffusion that is beneficial to heat of this graphite heat conducting heat radiation adhesive tape, also can play a supporting role to graphite, also can prevent that graphite entry material from coming off, avoid short circuit, thereby improved performance and the life-span of product.
For achieving the above object, the kind technical scheme that the utility model adopts is: a kind of graphite heat conducting heat radiation adhesive tape, comprise the first polyester film, the second polyester film and graphite linings, this upper and lower surface of the first polyester film is coated with respectively first, second high-temperature plastic adhesion coating, the opposing surface label of the second high-temperature plastic adhesion coating and the first polyester film is covered with described graphite linings, bonding by the 3rd high-temperature plastic adhesion coating between this graphite linings and the second polyester film; The opposing surface label of described the first high-temperature plastic adhesion coating and the first polyester film is covered with separated type material layer.
In technique scheme, further improved plan is as follows:
1. in such scheme, described the first polyester film, the second polyester film thickness are 1.8 ~ 2.2 μ m.
2. in such scheme, the thickness of described the first high-temperature plastic adhesion coating, the second high-temperature plastic adhesion coating and the 3rd high-temperature plastic adhesion coating is 2 ~ 4 μ m.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
The utility model graphite heat conducting heat radiation adhesive tape, has reduced the probability that graphite breaks, and adhesive tape local superheating is also avoided in the diffusion that had both been conducive to heat, also can play a supporting role to graphite, also can prevent that entry material from coming off, avoid short circuit, thereby improve performance and the life-span of product.
