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 sun-shading double-silver low-e coated glass, which solves the high transmission and low sun-shading requirements that cannot be solved by single silver low-e coated glass

Abstract

The invention discloses sunshade double-silver low-radiation reflective glass and a preparation method therefor. The sunshade double-silver low-radiation reflective glass comprises a glass substrate, a first silicon-aluminum alloy membrane, a second zinc-aluminum alloy membrane, a third silver membrane, a fourth nickel-cadmium alloy membrane, a fifth silicon-aluminum alloy membrane, a sixth zinc-aluminum alloy membrane, a seventh silver membrane, an eighth nickel-cadmium alloy membrane and a ninth silicon-aluminum alloy membrane. The preparation method comprises the following steps of 1) sintering a target; 2) pre-treating glass; and 3) carrying out coating treatment. The sunshade double-silver low-radiation reflective glass prepared on a common colorless transparent float glass substrate through interference on light by various metal materials is light grey in reflection color under sunlight, so that good decorating and energy-saving effects can be achieved; the product can be processed in a different place, so that the manufacturing cost of a processing enterprise is lowered; the glass can be further manufactured to hollow glass, so that better light-controlling and energy-saving effects can be 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 sun-shading double-silver low-emissivity coated glass and the prepared sun-shading double-silver low-emissivity 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 des...
