example 1

[0191] Example 1: Showcase

[0192] In order to illustrate the cooling effect of the selective radiation cooling coating, the application of the selective radiation cooling coating to a building is taken as an example below.

[0193] A stainless steel exhibition house with internal length, width, and height of 5m, 4m, and 3m is formed with a selective radiation cooling coating on the outside of the roof and four walls. The selective radiation cooling coating includes a bottom layer with a thickness of 20 μm from bottom to top. Lacquer resin layer (acrylic resin), the first radiative cooling functional layer (formula X) with a thickness of 100 μm, the second radiative cooling functional layer (formulation Y) with a thickness of 15 μm, and weather-resistant resin layer (polyester) with a thickness of 20 μm Vinylidene fluoride resin), the reflectivity of the selective radiation refrigeration coating is 91% at 0.3μm-2.5μm, and the emissivity at 7μm-14μm is 94%. Here, the outdoo...

Abstract

The invention relates to a radiation refrigeration functional coating and an application thereof. The radiation refrigeration functional coating is used for preparoing a radiation refrigeration function layer. The radiation refrigeration function layer is used for reflecting ultraviolet light and / or visible light and / or near infrared light in sunlight and emitting heat through an atmosphere windowin an infrared radiation mode, the radiation refrigeration function layer comprises a particle filler and radiation refrigeration function resin, and the particle filler is distributed in the radiation refrigeration function layer resin.

Description

[0001] related application [0002] This application claims the priority of the Chinese patent application filed on July 5, 2019, with application number 201910607455.2, entitled "Selective Radiation Refrigeration Coatings and Composite Materials and Application Methods thereof", which is hereby incorporated by reference in its entirety. technical field [0003] The invention relates to the technical field of material science, in particular to a selective reflection and emission radiation cooling functional coating and its application. Background technique [0004] The sun is a huge source of radiation. When the sun shines on the earth, part of the energy is absorbed by the atmosphere and part is reflected back to the universe. Due to the heat absorbed by the earth's surface, the surface temperature of objects on the earth is much higher than the temperature of the air above the surface. Cooling objects increases energy consumption and creates more greenhouse gas emissions. ...
