Embodiment Construction

[0014] Such as figure 1 As shown, the preferred embodiment of the present invention is a light-shielding thermal diffusion film, which includes a metal layer 2 arranged in sequence and a light-shielding layer 1 coated on the metal layer 2 . It also includes a release material layer 4 with an adhesive layer 3, and the release material layer 4 is attached to the other side of the metal layer 2 through the adhesive layer 3. The light-shielding layer 1 is composed of black ink. The adhesive layer 3 is an adhesive layer 3 of acrylic, silica gel, hot melt adhesive or epoxy resin. The metal layer 2 is composed of copper metal, aluminum metal, steel metal, nickel metal or silver metal material. The release material layer 4 is composed of single-sided release paper, double-sided release paper or PET release film.

Abstract

The invention discloses a shading thermal diffusion film, which comprises a metal layer and a light insulating layer coating the metal layer sequentially. The light insulating layer with black polymer is prepared on the surface of metal through the processing of a device to achieve the shading effect; the metal has the effects of thermal diffusion and electric conduction and thermal conduction; then, an adhesive layer is further adhered to the other surface of the metal layer, wherein an electric conduction adhesive layer can be adhered to play the roles of electric conduction and thermal conduction, while a non-electric conduction adhesive layer can be also adhered to play an insulation role; and the total thickness of the materials is within 0.035 mm, and the film resists the temperature between subzero 40 DEG C to subzero 10 DEG C or the temperature is controlled between 80 DEG C and 180 DEG C for use. The film is an ultrathin and high and low temperature resisting, and shading thermal diffusion material which is unavailable in the domestic market.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a light-shielding thermal diffusion film. Background technique [0002] As we all know, the shading film currently on the market only has a shading effect and does not have the function of thermal diffusion, especially in places where heat is generated such as electronic products, which hinders the diffusion of heat and easily damages the device. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the invention provides a light-shielding thermal diffusion film. [0004] The technical solution of the present invention is: a light-shielding thermal diffusion film, comprising a metal layer arranged in sequence and a light-shielding layer coated on the metal layer. [0005] Further improvements of the present invention include: [0006] It also includes a release material layer with an adhesive layer, and the release material layer is ...
