Problems solved by technology

At present, the traditional low-emissivity energy-saving glass basically uses metallic silver as the multi-layer film system of the low-emissivity layer, and other film layers mainly play the role of protecting and isolating the silver film layer. Therefore, this type of energy-saving glass has poor weather resistance and corrosion resistance when used, and the service life of glass products is easily affected by it. At the same time, the cost of off-site processing and transportation is high

Embodiment 1

[0022] refer to figure 1 Said, a multi-functional low-radiation energy-saving glass, a continuous deposition barrier layer, a titanium functional layer, a silver-titanium functional layer, and a protective layer are sequentially stacked on a coated glass substrate. The barrier layer is used to prevent sodium ions and calcium ions in the glass substrate from entering the functional layer to affect the energy-saving effect. The material of the barrier layer can be silicon oxide or silicon nitride. Silicon oxide or silicon nitride is non-toxic and pollution-free, and is resistant to corrosion and Wear-resistant, the thickness of this layer is 20-35nm; the titanium functional layer is a low emissivity layer, which is used for infrared high reflection design, and the titanium functional layer includes the first titanium oxide film layer 31, the first metal titanium film layer 32, the second titanium oxide film layer Layer 33, sequentially stacked and continuously deposited the ...

Embodiment 2

[0025]The invention discloses a method for preparing multifunctional low-radiation energy-saving glass, which adopts manual or automatic coating, and puts the coating surface of the glass substrate in the direction facing the target material into the substrate frame and sends it into the magnetron sputtering equipment. After the glass substrate is sent into the magnetron sputtering chamber, turn on the mechanical pump to evacuate. According to the production cycle requirements, when the vacuum degree reaches the order of 1Pa, start the transmission system and open the isolation valve between the chamber and the buffer chamber. , the substrate rack enters the buffer chamber, open the vacuum to about 0.1Pa, open the isolation valve, enter the process chamber, turn on the vacuum pump to evacuate to 1.0-4Pa, fill in the working gas argon, process gas oxygen or nitrogen (according to Silicon oxide and silicon nitride are different, for the convenience of the front and rear processes...

Abstract

The invention discloses low-radiation energy-saving glass with multiple functional layers and a preparation method of glass. The low-radiation energy-saving glass with the multifunctional layer mainly comprises a glass substrate, a barrier layer, a titanium-based functional layer, a silver titanium-based functional layer and a protective layer. The two functional layers can realize low radiance rate, high visible light luminousness and high infrared reflectivity, the colors of thin films are neutral and soft, and the distribution of the thin films is uniform; relative to conventional silver-based low-radiation energy-saving glass, the low-radiation energy-saving glass with the multiple functional layers has the characteristics of weather resistance, high corrosion resistance and stable performance after long-time use, and is low in cost, simple in technological process, adjustable in colors during the production process and low in radiance rate.

Description
