Problems solved by technology

Its shortcoming mainly contains two: the first, the composite process of multi-layer polymer polyester material film is more complicated
Second, in high molecular organic polymer molecules, the chemical bond C=H between carbon and hydrogen elements is very sensitive to ultraviolet light in the solar spectrum. Long-term exposure to ultraviolet light can easily cause the chemical bond to break, and the macroscopic performance is macromolecular organic polymerization. Physical aging damage
Compared with the traditional glass carrier mirror, which has been exposed to sunlight for nearly 30 years and still retains a reflectivity as high as 97%, there is still a considerable gap, resulting in a significant shortening of its service life

Embodiment 1

[0032] Such as figure 1 The first solar reflector flexible mirror film shown is the most basic mirror film structure of the present invention, and it has a five-layer film composite structure: viewed along the sunlight incident direction, it is successively one layer of transparent flexible inorganic material carrier film 1 , a layer of reflective film 2 of metal material, a layer of protective film 3 of metal material, a layer of pressure-sensitive adhesive adhesive film 4 and a layer of pressure-sensitive adhesive peeling protection film 5. Among them, the transparent and flexible inorganic material carrier film 1 is an ultra-thin flexible glass film with a commercial name of "Willow Glass". The thickness of the ultra-thin flexible glass film is δ=100 μm. The performance of breaking, also has the characteristics that the energy is not easily absorbed when sunlight passes through, and it is not sensitive to ultraviolet light. The metal reflective film 2 is made of silver met...

Embodiment 2

[0035] Such as figure 2 The film composite structure of the second solar reflector flexible mirror film shown is basically the same as that of Embodiment 1. The difference is that the metal protective film 3 is an aluminum metal film 3a and its surface naturally accompanied by an aluminum oxide film 3b, or an aluminum metal film 3a and its surface a dense aluminum oxide film 3b that is forcibly oxidized. In this way, replacing the copper metal film with aluminum metal film can not only effectively reduce the material cost, but also the dense Al attached on the aluminum metal surface 2 o 3 The film has excellent resistance to moisture and acid and alkali corrosion, so as to maintain the stability of the mirror film and prolong the service life of the mirror film.

Embodiment 3

[0037] Such as image 3 The film composite structure of the third flexible mirror film for sunlight reflector shown is basically the same as that of Embodiment 1. The difference is that a layer of nano-hydrophobic coating 6 is coated on the transparent flexible inorganic material carrier film 1 (ie ultra-thin flexible glass film). Described nano-hydrophobic coating 6 can select water-soluble TiO for use 2 Nano-coating, also can choose water-soluble Al 2 o 3 Nano coatings. This kind of coating can quickly form a layer of nano-hydrophobic film when it is directly coated, which is firmly attached to the surface of the ultra-thin flexible glass film, and has various functions such as waterproof, dustproof, antibacterial, heat-resistant, acid and alkali resistant, and UV-resistant. , It also makes the outer surface of the reflector placed outdoors have a self-cleaning function, easy to clean (washing or blowing with compressed air), and not easy to bind dust, so as to ensure it...

Abstract

The invention discloses a flexible reflector film of a sunlight reflector. The flexible reflector film is of a multi-layer film material composite structure, when the flexible reflector film is viewed in the incidence direction of sunlight, the flexible reflector film sequentially comprises a transparent flexible inorganic material carrier film, a metal material reflection film, a metal material protecting film, a pressure-sensitive adhesive film and a pressure-sensitive adhesive stripping protecting film. It is optimized that the transparent flexible inorganic material carrier film is an ultra-thin flexible glass film or a transparent grapheme film. The sunlight reflector made of the reflector film has sunlight high-transmitting performance, ultraviolet radiation resistant performance, is resistant to solarization and durable, and has the advantages of being soft, ultra-thin and light. The flexible reflector film is easy to manufacture, convenient to convey, easy to install, stable in work and long in service life. Meanwhile, after a nanometer material hydrophobic film or an ultraviolet-resistant self-cleaning protecting film is arranged on the surface of transparent flexible inorganic material in a composite mode, the sunlight reflector arranged outdoors can also have a self-cleaning function, and be free of dust, resistant to oil contamination, acid, alkali and ultraviolet light, and easy to clean.

Description

technical field [0001] The invention relates to sunlight reflection technology, in particular to a flexible mirror film of a sunlight reflection mirror. Background technique [0002] At present, among mirror devices, mirrors with glass as the main body are the most widely used. Especially in the field of solar thermal power generation, most of the existing parabolic trough mirrors, hyperbolic parabolic dish mirrors, spherical curvature dish mirrors, and spherical micro-curvature heliostats, etc. It is made of a curved glass carrier, and its processing overview is as follows: the flat glass is firstly bent into a curved glass carrier with a set curvature by using a forming mold, then the curved glass carrier is cleaned, and then a layer of silver metal reflection is coated on the curved glass carrier. Thin film, then coated with a layer of copper metal protective film, and finally coated with a protective layer. [0003] The overall advantage of these reflectors for outdoor...
