Problems solved by technology

Therefore, the thermochromic functional fillers in the prior art do not have a high solar spectrum reflection effect, and the prepared thermochromic polymer composites often do not have a good high solar spectrum reflection function, which is difficult to realize in hot summer The cooling effect cannot achieve the heating effect by absorbing sunlight in the colder winter and spring, let alone realize the intelligent adjustment of heating and cooling functions according to seasonal temperature changes
[0005] To sum up, currently in the preparation of solar spectrum reflective polymer-based composite materials, the high reflective cooling materials prepared by the prior art have certain limitations, no matter in the hot summer or in the cold winter, they can realize the solar spectrum. High reflectivity; at the same time, the thermochromic functional filler does not have a high solar spectrum reflection effect, and the prepared thermochromic polymer composite material does not have a good high solar spectrum reflection function, and it is difficult to realize the cooling function
