Abstract

The invention belongs to the technical field of film materials, and particularly relates to a transparent heat-insulating ultraviolet-proof composite film based on a photonic quasicrystal material anda preparation method thereof. The composite film structurally comprises a transparent substrate layer, a photonic quasicrystal functional film layer, an adhesive layer and a strippable layer. The photonic quasicrystal film is formed by polymer core-shell-structure microspheres and infrared functional nanoparticles which are stacked and arranged in a three-dimensional ordered manner through a specific process, and has adjustable structure color and optical transparency. The structural color, transparency and ultraviolet and infrared blocking wavelength range of the film can be regulated and controlled by regulating and controlling the core microsphere size, shell thickness and refractive index of the core-shell-structure microspheres and the content of the infrared functional nanoparticles, and the ultraviolet and infrared blocking efficiency can also be controlled by regulating and controlling the thickness. The formed composite film is high in ultraviolet light blocking efficiency, high in visible light transmittance and good in heat insulation effect, and has excellent transparent heat insulation ultraviolet-proof and explosion-proof performance, and can be used for energy conservation, explosion prevention and the like of automobiles and building glass.

Description

technical field

[0001] The invention belongs to the technical field of film materials, and in particular relates to a transparent heat-insulating and anti-ultraviolet film and a preparation method thereof. Background technique

[0002] For functional reasons such as aesthetics and effective use of sunlight, glass is more and more used in the construction field and the automotive industry, but sometimes its good light transmission also makes the sunlight too strong, which brings a series of problems. We know that the sunlight reaching the earth's surface is mainly composed of infrared light, visible light and ultraviolet light, and the radiated heat is mainly concentrated in the visible light region and infrared light region. In addition, ultraviolet light has high energy. A moderate amount of ultraviolet light is beneficial to health, but excessive ultraviolet radiation can easily damage the eyes and skin and induce diseases; ultraviolet radiation is also the biggest cause o...
