Problems solved by technology

The process of producing coated glass by sol-gel method is simple and has good stability. The disadvantage is that the light transmittance of the product is too high and the decoration is poor.
[0007] At present, there are not many researches on the production of green coated glass. It solves the problem that the production of green coated glass needs to be purchased in advance in large quantities. The green glass produced by the interference agent ferric oxide is small, the production frequency is small, and the production cycle is long. It cannot be coated within 15 days after the original glass is produced. The original glass for coating is generally required to be used within 15 days after production. Can avoid film quality problems during coating
Generally, the production of green coated glass is to carry out coating treatment on the original green glass that has been stored for a long time. Therefore, the film quality of the produced green coated glass is prone to quality problems, which will reduce the service life of green coated glass and the effect of light control and energy saving.

Abstract

The invention discloses a green low-radiation reflective glass and a preparation method therefor. The green low-radiation reflective glass comprises a glass substrate, a first nickel-chromium alloy film, a second silicon-aluminium alloy film, a third zinc-aluminium alloy film, a fourth silver layer; a fifth nickel-chromium alloy film, a sixth zinc oxide-aluminium alloy film and a seventh silicon-aluminium alloy film which are sequentially and compactly laminated. The preparation method comprises the following steps: 1) sintering a target material; 2) pre-treating a glass material; and 3) carrying out coating treatment. According to the low-radiation reflective glass prepared by virtue of interference on light by various metal materials on a common colorless transparent float glass substrate, the reflection color of the glass in the sun is green and thus good decorating and energy-saving effects are achieved; the product can be processed in different places, so that the manufacturing cost of an enterprise is lowered; and the glass can be further manufactured to hollow glass, so that better light-controlling and energy-saving effects are achieved.

Description

technical field [0001] The invention relates to a method for preparing coated glass and the coated glass prepared by the method, in particular to a method for preparing low-radiation coated glass and the prepared low-radiation coated glass. Background technique [0002] Coated glass (Reflective glass) is also called reflective glass. Coated glass is coated with one or more layers of metal, alloy or metal compound films on the surface of the glass to change the optical properties of the glass to meet certain requirements. Coated glass can be divided into the following categories according to the different characteristics of the product: heat reflective glass, low-emissivity glass (Low-E), conductive film glass, etc. [0003] There are many production methods for coated glass, such as vacuum magnetron sputtering, vacuum evaporation, chemical vapor deposition, and sol-gel methods. Magnetron sputtering coating glass can design and manufacture multi-layer complex film system by...
