Problems solved by technology
[0004] Therefore, in the prior art, graphite heat sinks are pasted on the heat-generating parts of consumer electronic products by way of pasting films to play a cooling role. However, the existing films have poor tensile properties, and the appearance is usually transparent or white matte visually, which affects aesthetics

Abstract
The invention discloses an external film of an electronic product and a preparation method of the external film. The external film of the electronic product comprises an anti-fingerprint film; a decorative film arranged on the inner surface of the anti-fingerprint film through a first adhesion layer; a graphite flake layer arranged on the inner surface of the decorative film through a second adhesion layer; a first PET transparent film arranged on the inner surface of the graphite flake layer through a third adhesion layer; a PET blue thin film arranged on the inner surface of the first PET transparent film through a fourth adhesion layer; a silica gel layer arranged on the inner surface of the PET blue thin film; a second PET transparent film arranged on the inner surface of the silica gel layer; and a label arranged on the inner surface of the second PET transparent film. The external film of the electronic product disclosed by the invention not only can improve the tensile resistance and the high temperature resistance, but also improves the beautiful degree, and can improve the flame retardance and improve the heat conduction and dissipation.
Description
technical field [0001] The invention relates to an external film for electronic products and a preparation method thereof. Background technique [0002] At present, with the continuous development of electronic technology and the continuous upgrading of electronic products, the size of its working components is getting smaller and smaller, its working speed and efficiency are getting higher and higher, and its heat generation is also increasing. Therefore, it is not only required to be equipped with a corresponding heat sink, but also to ensure that the heat sink has a stronger heat dissipation capacity to ensure the reliability of product performance and prolong its service life. Effective heat dissipation is crucial to the stable operation and long-term reliability of electronic products. important. [0003] Graphite heat dissipation material, because of its unique low density (compared to metals), high thermal conductivity and heat dissipation coefficient and low thermal...
