Problems solved by technology

[0004] (1). Low spectral reflectance;
[0005] (2). The adhesion between the film layer and the substrate and between the film layer and the film layer is poor, and it is easy to fall off;
[0006] (3). High temperature resistance and deliquescence resistance are not strong, high temperature or deliquescence environment can make the surface of the film vulnerable to damage, and the spectrum is prone to drift

Embodiment Construction

[0034] The structure of the wide-angle wide-spectrum reflective film of the present invention is as figure 1 Shown. among them

[0035] The first transition layer 2 is made of high-purity chromium (nickel, palladium, titanium) (purity 90%-100%) vapor-deposited, and the thickness is controlled between 20-100nm;

[0036] The second transition layer 3 is a mixed layer of chromium (nickel, palladium, titanium), silver (aluminum), and a film layer of a mixed material obtained by simultaneously vaporizing two materials of chromium (nickel, palladium, titanium) and silver (aluminum). The percentage ratio can be controlled in the range of 30% / 70%~70% / 30%, and the thickness of the entire film layer is between 10-100nm;

[0037] The metallic silver (aluminum) film layer 4 is vapor-deposited with a purity of more than 99.9% pure silver (aluminum), and the thickness is between 130 nm and 4000 nm;

[0038] The reinforcing film layer 5 is a combination of layers composed of high and low refract...

Abstract

The present invention relates to a wide-angle broad-spectrum reflection film and its production method. The reflecting film includes glass base. On the glass base first transition layer, metal film layer and reinforced film layer are successively deposited, perfectly, between first transion layer and metal film layer a second transion layer can be added. Said invention adopts double transion layer structure, and its spectral reflectance is high.

Description

Technical field [0001] The invention relates to a reflective film, in particular to a high-performance wide-angle and broad-spectrum reflective film and a manufacturing method thereof. Background technique [0002] The network technology in the information age has made the need to share information and aggregate information increasingly prominent, which has created a great demand for super-large screen display. The traditional display technology using CRT as the image source is due to its large size, heavy weight, and its own limitations. The limitation of brightness has gradually become a bottleneck restricting its development. Instead, large-screen projection display systems based on LCD (Liquid Crystal Display), DLP (Digital Light Processing), and LCOS (Liquid Crystal on Silicon) mechanisms are used, especially DLP-based display systems are popular for their fast response speed, high light utilization rate, and high resolution. [0003] However, the performance of the key comp...
