Abstract

The invention discloses a stretchable radiation cooling adhesive tape as well as a preparation method and application thereof, and belongs to the field of nano materials and application, namely poly (4-methyl-1-pentene) doped with titanium dioxide nano particles and dioctyl phthalate is used as a cooling layer of the adhesive tape, and nitrile rubber is used as a bonding layer of the adhesive tape. The adhesive tape is prepared by adopting a blade coating technology, the method is simple, and large-size continuous preparation can be realized. The adhesive tape prepared by the invention has high stretchability, relatively strong adhesive property and good waterproof performance. The adhesive tape can be used for cooling electronic equipment, and experimental results show that the adhesive tape prepared by the invention can realize the highest 9.3 K sub-environment cooling, and the surface temperature of a mobile phone can be reduced by 25.1 K.

Description

technical field [0001] The invention relates to a stretchable radiation cooling adhesive tape and a preparation method thereof, which relate to the use of inorganic particle doping to control the spectral selectivity of the composite material and plasticizer doping to improve the stretchability of the composite material and the research on the cooling performance of the composite material. Nanomaterials and applications. Background technique [0002] Radiation cooling is a passive and spontaneous cooling method, which does not consume any external energy, and transfers the heat on the surface of the object to outer space through infrared radiation to achieve material cooling. The earth's atmosphere is transparent to electromagnetic waves of certain wavelength bands, especially between 8-13 μm, which coincides with the wavelength range of black body radiation at room temperature. Infrared radiation can transfer heat from objects on Earth through this atmospheric transparent ...
