Abstract

The invention discloses an intelligent sunshade material and a preparation method and application thereof. The main active components of the sunshade material are composed of ultraviolet absorbing medium, visible light-near infrared selective absorbing particles, medium and far infrared selective emission medium, photosensitive medium and temperature sensitive medium Composition, prepared by step-by-step grinding and dispersion, mixing. The sunshade material disclosed by the invention has excellent sunshade heat insulation and self-cooling effects, high anti-ultraviolet performance, certain temperature and light adaptation characteristics, good film-forming properties and adhesion, and can be widely used in various sunshade products , play the role of heat insulation and energy saving. At the same time, the materials used are safe, non-toxic, free of volatile organic compounds, and environmentally friendly; the preparation process is relatively simple, and the production cost is controllable.

Description

technical field [0001] The invention relates to the technical field of sunshade materials, in particular to an intelligent sunshade material and a preparation method and application thereof. Background technique [0002] The power of sunlight reaching the ground in clear weather can reach 1000 W / m 2 Above, its composition mainly includes about 7% ultraviolet (wavelength below 400 nm), 50% visible light (wavelength between 400 and 750 nm) and 43% near infrared (wavelength between 750 and 2500 nm). Oxygen, water vapor and carbon dioxide in the air all absorb sunlight to varying degrees, especially water vapor and carbon dioxide have strong absorption of near-infrared, and sunlight radiation will produce strong heating of water vapor, carbon dioxide and other gases in the air As a result, if the gas is confined to a closed environment lacking thermal convection at this time, the internal temperature will rise rapidly and be significantly higher than the ambient temperature. F...
