Novel aerogel heat insulation film

Abstract

The invention discloses a novel aerogel heat insulation film. The heat insulation film comprises a heat-insulating film body, a base layer is arranged in the middle of the heat insulation film body, aphase change layer, an outer aerogel layer and a protective layer are sequentially arranged on the upper side of the base layer, an inner aerogel layer and a release film layer are sequentially arranged on the lower side of the base layer, the outer aerogel layer, the phase change layer, the base layer inner aerogel layer and the release film layer are sequentially bonded through bonding layers,silicon dioxide aerogel serves as a heat insulation main body material, polydimethylsiloxane serves as a protection material, a novel heat insulation material which has certain mechanical strength, flexibility, corrosion resistance, moisture resistance and environmental protection is formed, and through a composite phase change material, heat storage is achieved, and constant-temperature environment simulation is achieved. Compared with a traditional aerogel heat insulation film, the novel heat insulation film is better in tolerance to humidity and pH value, and the powder falling condition does not exist. Therefore, the novel heat insulation film provided by the invention has a great prospect in the field of heat insulation.

Description

technical field [0001] The invention relates to the fields of heat insulation and directional heat conduction, in particular to a novel airgel heat insulation film. Background technique [0002] With the advent of the 5G era, the power consumption of consumer electronic products is increasing, and the heat production is correspondingly increasing. From the perspective of the stability, safety and service life of electronic products, high-power electronic products must be treated with heat conduction and heat dissipation. In order to prevent the temperature from interfering with some important components of the product or causing harm to users, in thermal design, directional thermal conduction and heat dissipation design is usually used, in which thermal insulation materials play an important role. [0003] At present, the commonly used heat insulation materials are divided into three categories: porous materials, heat reflective materials and vacuum materials. Porous mater...
