| description | The invention relates to a heat conducting reflection film. The heat conducting reflection film includes a reflection layer and a diffusion layer; one surface of the reflection layer is provided with a heat conducting layer; the heat conducting reflection film is formed through multi-layer co-extrusion; the heat conducting layer contains heat conducting particles; and the weight percentage of the heat conducting particles in the heat conducting layer ranges from 1% to 50%. An A/B/C-layer co-extrusion method is adopted; a thick sheet is extruded out from a mould head; the thick sheet is subjected to casting, biaxial stretching, heat setting and coiling; and the heat conducting reflection film can be obtained. The heat conducting reflection film of the invention has excellent heat conductivity, so that deformation phenomena of the reflection film such as bending and wrinkling due to uneven heating can be avoided; the heat conducting reflection film also has a diffusion property; and therefore, production and use cost can be reduced. The heat conducting reflection film is suitable for the liquid crystal display industry. |
