example 1

[0077]

[0078] The coating film system in Example 1 was tested under different conditions, and the changes in total light reflectance YD65 / 2° and coating adhesion were observed. Among them, the measurement of the total light reflectance YD65 / 2° is based on the ISO6719:2010 standard and the joint ISO / CIE standard, ISO10526:1999 / CIES005 / E-1998 (the standard illuminant used by CIE for quantitative analysis of chromaticity). Coating adhesion is measured according to the Baigrid cross scratch adhesion test described in ISO2409:2013 and GB / T9286-1998 standards. Concrete coating film system test result in example one is as follows:

[0081]

[0082] The coating film system in Example 2 was tested under different conditions, and the changes in total light reflectance YD65 / 2° and coating adhesion were observed. Among them, the measurement of the total light reflectance YD65 / 2° is based on the ISO6719:2010 standard and the joint ISO / CIE standard, ISO10526:1999 / CIES005 / E-1998 (the standard illuminant used by CIE for quantitative analysis of chromaticity). Coating adhesion is measured according to the Baigrid cross scratch adhesion test described in ISO2409:2013 and GB / T9286-1998 standards. Concrete coating film system test result in example two is as follows:

Abstract

The invention discloses a high-temperature-resistant and corrosion-resistant high-reflection mirror surface coating film system, and relates to the technical field of film plating. The system includesa metal substrate, wherein a first auxiliary film layer, a high-reflection silver film layer, a second auxiliary film layer, a low-refractive-index coating and a high-refractive-index coating are sequentially plated on the film plating surface of the metal substrate, and the first auxiliary film layer and the second auxiliary film layer are both metals plated by adopting a common sputtering process; and a silicon nitride (Me: Si) NX compound which is a multifunctional comprehensive auxiliary layer, can provide the adhesion promotion, diffusion barrier and anti-oxidation effects, so that the high-reflection mirror surface coating film system can have the advantages of high durability, high reliability and the like under the high-temperature and corrosive environment conditions. Preferably,the metals or metal alloys in the first auxiliary film layer and the second auxiliary film layer are the same. Preferably, a metal interface layer is further arranged between the first auxiliary filmlayer and the high-reflection silver film layer and is used for further restraining the transverse migration of silver atoms.

Description

technical field [0001] The invention relates to the technical field of thin film plating, and more specifically refers to a high-reflection mirror coating film system with high temperature resistance and corrosion resistance. Background technique [0002] Highly reflective specular reflectors are widely used in lighting engineering, equipment applications such as: flashlights, projectors, solar energy collection and decorative applications, and its emerging market requirements are applications in the field of concentrated solar power (CSP) and in MC-COB modules Application as back reflector for LED. [0003] One prior art technique is to plate a material with high reflectivity, such as aluminum or silver, on a metal substrate to make a surface reflector. In addition, a durable and reflective enhancing layer is usually additionally applied over the aluminum or silver coating, most commonly a highly reflective coating such as aluminum or silver on a metal substrate; on top of...
