Embodiment Construction
[0028] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.
[0029] The invention adopts the magnetron sputtering method, selects the metal object as the target material, and coats the nitride, metal object or metal oxide compound layer on the glass substrate under a specific atmosphere, and coats the protection layer to obtain it. The specific atmosphere is an inert gas or a gas mixed with oxygen and argon. The inert gas is generally argon. In a pure argon atmosphere, the corresponding functional layer can be obtained by using a nickel-chromium alloy target and a silver target by magnetron sputtering. If 10-80% (preferably 20-50%) of oxygen is mixed in the argon gas, the metal oxide layer and the metal oxide composite layer can be obtained. If the mixed gas of nitrogen and argon is used as the atmosphere, and the volume ratio of nitrogen and argon is 10-40:100, a metal nitride layer or a silicon nitride layer ...

Abstract
The invention relates to low radiation coated glass with a deep jewelry blue reflected color and a manufacturing method thereof. The invention aims to provide coated glass with a deep jewelry blue reflected color, which has bright and durable color, stable reflected color if observed from different angles, and low radiation property. The low radiation coated glass takes glass as a substrate (1); a silicon nitride bottom layer (2), a functional layer (3) and a protective layer (4) are plated on the single surface of the glass in sequence; the three layers are deposited on the surface of the glass substrate layer by later by adopting a vacuum magnetron sputtering technology; and the low radiation coated glass is characterized in that a chrome barrier layer (3-1), a nickel-chromium barrier layer (3-2), a silver layer (3-3) and a chrome layer or a nickel-chromium oxide composite layer (3-4) are arranged in the functional layer (3) from the inner part to the outer part in sequence.
Description
technical field [0001] The invention relates to the surface treatment of glass, especially the low-radiation coated glass with deep sapphire blue reflection color and its production method. Background technique [0002] Coated glass, especially low-e coated glass, not only has the function of lighting, shading and energy saving, but also has an important effect on the beautification and decoration of buildings. Modern commercial buildings and residential buildings have higher and higher decorative requirements for glass, and various functions and colors are the goals pursued by architects. Coated glass manufacturers design different colors of coated glass to suit different color requirements. Low-emissivity coated glass is a functional material that prohibits the transmission of most infrared frequencies and allows visible light to pass through. Due to its high visible light transmittance and excellent heat insulation performance, low-e coated glass is widely used in build...
