Description

Technical Field

[0001] The utility model relates to the field of adhesive tapes, in particular to a vehicle-mounted screen heat dissipation adhesive tape. Background Art

[0002] With the rapid development of science and technology, electronic products have become an indispensable part of our lives. However, as the performance of electronic equipment improves, its heat dissipation problem is becoming increasingly serious. In particular, the performance of car screens is constantly improving, but it also brings more serious heat dissipation problems. Traditional tapes only have the function of heat dissipation, but not the function of isolating heat sources, so the heat dissipation effect is not ideal.

[0003] For example, the Chinese patent with publication number CN220335108U discloses an OCA tape for screens, which relates to the field of OCA optical adhesive technology. It includes, from top to bottom, a protective film layer, a heat-conducting layer, an optical adhesive layer, a release film layer, and a brightening layer arranged between the protective film layer and the optical adhesive layer. An anti-glare layer is also arranged between the protective film layer and the optical adhesive layer. An anti-stretching layer is also arranged under the release film layer. The above-mentioned OCA tape for screens only has the effect of heat dissipation, but not the effect of isolating heat sources, resulting in unsatisfactory heat dissipation effect of the screen.

[0004] In view of this, it is necessary to provide a vehicle-mounted screen heat dissipation tape. Summary of the invention

[0005] The utility model provides a vehicle-mounted screen heat dissipation tape, which effectively solves the problem that the heat dissipation effect of the existing tape is not ideal.

[0007] A vehicle-mounted screen heat dissipation tape comprises a thermal insulation film, a copper foil layer, a first layer of high thermal conductivity acrylic film coated on the upper end surface of the copper foil layer, and a second layer of high thermal conductivity acrylic film coated on the lower end surface of the copper foil layer. The thermal insulation film is bonded to the lower end surface of the second layer of high thermal conductivity acrylic film, and a release film is bonded to the lower end surface of the thermal insulation film.

[0008] Furthermore, the thermal insulation film includes a transparent PET substrate layer, a self-adhesive layer coated on the upper end surface of the transparent PET substrate layer, and an aerogel layer coated on the lower end surface of the transparent PET substrate layer, the aerogel layer is bonded to the lower end surface of the second layer of high thermal conductivity acrylic film, and the self-adhesive layer is bonded to the release film.

[0009] Furthermore, the thickness of the first layer of high thermal conductivity acrylic film and the second layer of high thermal conductivity acrylic film are both in the range of 0.025 mm to 0.15 mm.

[0010] Furthermore, the thickness of the copper foil layer ranges from 0.025 mm to 0.15 mm.

[0011] Furthermore, the thickness of the transparent PET substrate layer is in the range of 0.005 mm to 0.025 mm, and the thickness of the aerogel layer is in the range of 0.08 mm to 0.5 mm.

[0012] The beneficial effects of the utility model are as follows: the screen body can be insulated by using the diaphragm heat, while the copper foil layer, the first high thermal conductivity acrylic adhesive layer and the second high thermal conductivity acrylic adhesive layer are used for heat dissipation, thereby ensuring that the screen body achieves the heat dissipation effect.
