Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, the preferred embodiment of the present invention is a diffusion heat insulation film, which includes a base layer 1 , a heat insulation adhesive layer 2 and a metal layer 3 arranged in sequence. The diffusion heat insulation film further includes a release material layer 5 with an adhesive layer 4 , and the release material layer 5 is bonded to the metal layer 3 through the adhesive layer 4 . The base layer 1 is a polyester film base, polycarbonate base, polyimide base, polypropylene base, Teflon base or nylon base. The adhesive layer 4 is an adhesive layer 4 of acrylic, silica gel, hot melt adhesive or epoxy resin. The metal layer 3 is composed of copper metal, aluminum metal, steel metal, nickel metal or silver metal material. The thermal insulation adhesive layer 2 is insoluble water-based aerosil gel or carbon aerogel. The r...

Abstract

The invention discloses a diffusion and heat insulating film which sequentially comprises a substrate layer, a heat insulating rubber layer and a metal layer. The diffusion and heat insulating film has the advantages that the rubber layer is pressed on a substrate by means of equipment processing and then composited with metal, the rubber layer is mixed with the heat insulating layer according to a certain proportion, and a rubber layer with a release material is further composited on the surface of metal by means of coating. The total thickness of the film is controlled within 0.05mm, and the film can be coiled to be convenient for use. The diffusion and heat insulating film overcomes the defects in the prior art and has functions of diffusion and heat insulation.

Description

technical field [0001] The invention relates to a thermal insulation film, in particular to a diffusion thermal insulation film. Background technique [0002] With the rapid development of the electronic industry, electronic devices are becoming more and more popular in modern society, such as personal computers, mobile phones, servers, GPS navigation devices and other household electronic devices, industrial electronic devices and information communication equipment. Many and powerful. Electronic devices have more and more functions and are more and more powerful, correspondingly, their internal chips or electronic modules are also more and more, and their operating speeds are getting faster and faster. Internal chips or electronic modules run faster and faster, generating more and more heat, and more and more heat energy gathers at a certain point of the chip or electronic module. At present, the diffusion film in the domestic market does not have the heat insulation eff...
