Problems solved by technology

However, the traditional radiative cooling film needs to form a metal film layer on the cooling film by magnetron sputtering and other methods. The cooling effect of the cooling film obtained in this way is not good. At the same time, the process is complicated, the cost is high, and the metal film layer is easy to oxidize and fail.

Abstract

The invention relates to a radiation refrigeration film, a preparation method thereof and a product. According to the radiation refrigeration film, a first reflection layer, a radiation refrigerationfunction layer and a second reflection layer are arranged in a stacked mode, and the radiation refrigeration film with the good refrigeration effect can be obtained without additionally machining andforming a metal film layer on the radiation refrigeration film. The first reflection layer can improve the reflection of an ultraviolet band, the transmittance of visible light and infrared bands is not influenced basically, and the reflectivity of the radiation refrigeration film can be effectively improved. The radiation refrigeration function layer can provide a good refrigeration effect, the second reflection layer can reflect sunlight energy back to the atmosphere to improve the refrigerating effect, meanwhile, the first reflection layer, the radiation refrigeration function layer, and afirst filler, the radiation refrigeration filler and a second filler in the first reflection layer can be used for cooperatively improving the overall reflectivity of the radiation refrigeration film,so that the refrigeration effect of the radiation refrigeration film is further improved.

Description

Technical field [0001] The present invention relates to the field of radiation refrigeration, and in particular, to a radiation refrigeration membrane, a preparation method, and a product. Background technique [0002] Under the trend of global warming, refrigeration technology has become a hot spot study. Radiation refrigeration is widely used due to its characteristics of environmentally friendship, due to its excellent refrigeration effect. In the radiation refrigeration process, it is usually used to perform radiation of sunlight to achieve a refrigeration effect using a radiation refrigeration membrane. However, conventional radiation refrigeration membranes need to form a metal film layer on the refrigeration membrane by magnetron sputtering, so that the refrigeration membrane refrigeration effect is poor, and the process is complicated, high cost, and the metal film layer is easily exposed to oxidation. Inventive content [0003] Based on this, it is necessary to provide ...
