Problems solved by technology

[0003] The shortcoming of the silver mirror produced by existing method has: (1) film layer is thicker, has reached micron level, contains precious metals such as Ag in the product, and cost is higher, and its fastness is relatively poor simultaneously, and surface hardness is low, and molding is monotonous And the color is single; (2) there is only a "white" reflection effect, and it cannot form a more distinctive color style on the surface; (3) it needs to be prepared by a chemical redox method, which has a long production cycle, poor stability, and high cost; ( 4) the conversion rate of silver nitrate is only about 30%, and the thickness of the silver layer is uneven, so it is difficult to produce larger products of specification, and there are defects such as silver mirror production efficiency is low, and product quality is unstable; (5) product cannot realize reliable Tempering performance, so it is impossible to implement follow-up processing such as modification and cutting by outsourcing factories; (6) Glue bonding processing is troublesome and poor stability

Abstract

The invention provides sky blue mirror reflection coated glass. The sky blue mirror reflection coated glass comprises a first metal absorption layer, a first medium layer and a second metal absorption layer. The first metal absorption layer, the first medium layer and the second metal absorption layer are orderly arranged on a base from bottom to top. The first metal absorption layer comprises a metal or alloy material with an extinction coefficient of 2.0 or more. The first medium layer comprises a medium material with a film refractive index of 2.0-2.7. The second metal absorption layer comprises a metal or alloy material with an extinction coefficient of 2.5 or more. The preparation method creatively breaks through the limitation of the conventional silver mirror glass preparation technology and white reflection effects, adopts a magnetron sputtering method, realizes layer-by-layer coating of the glass surface with a film material with an appropriate refractive index and can prepare mirror reflection glass with blue reflection effects.

Description

technical field [0001] The invention belongs to the technical field of glass deep processing and preparation, and specifically relates to a method of coating a variety of inorganic material composite films on the surface of glass through large-scale magnetron sputtering equipment, and through optical and physical effects such as interference and reflection of each film layer on light, So that the glass has a mirror glass with sky blue (Chinese blue) reflection effect. Background technique [0002] At present, the existing silver mirror coating processing method is usually: first use cleaning powder and tap water to clean and polish the surface of the glass substrate, then spray the active agent, wait for a period of time and then rinse with deionized water, and then silver The two materials of mirror stock solution A and B are sprayed on the glass surface respectively, and acetaldehyde and other organic substances are used as redox catalysts to form a layer of silver mirror ...
