Solar control coated glass capable of being used in one piece and preparation method of solar control coated glass

Abstract

The invention discloses a solar control coated glass capable of being used in one piece and a preparation method of the solar control coated glass. The coated glass comprises a glass substrate and a coating layer arranged at one side surface of the glass substrate, wherein the coating layer sequentially comprises a dielectric barrier layer, a first sacrificial layer, a functional layer, a second sacrificial layer, a dielectric support layer and a top protective layer which are sequentially arranged from the glass substrate to the outer side. The solar control coated glass capable of being used in one piece according to an embodiment of the invention is good in weather resistance and excellent in decorative effect and can be used in one piece.

Description

technical field [0001] The invention relates to the technical field of coated glass, in particular to a single-piece sunlight-controlled coated glass and a preparation method thereof. Background technique [0002] Modern buildings are often equipped with large-area windows, especially large buildings such as commercial buildings, large shopping malls and office buildings often use glass curtain walls, resulting in a large amount of sunlight entering the room through the glass curtain walls. In hot summer, the incident solar radiation energy is more than The heat lost through the glass curtain wall causes the indoor temperature to continue to rise, which increases the energy consumption of indoor air conditioning and refrigeration. At this time, it is necessary to use sunlight control coated glass to reduce the sunlight transmittance through the absorption and reflection of sunlight by the functional layer. The indoor solar radiant heat reduces the energy consumption of the a...

Problems solved by technology

as known glass / Si 3 N 4 / NiCr / CrN / Si 3 N 4 The solar control film system of the structure uses NiCr and CrNx as the functional layer, but both are not resistant to acid and salt spray corrosion, and the outermost layer of Si 3 N 4 Not resistant to alkali corrosion; also glass / SnO x / SSTN x / SnO x Film structure, but functional layer SSTN x Not resistant to acid corrosion, SnO x The texture is soft and cannot provide sufficient mechanical protection for the functional layer; another known glass / Si 3 N 4 or TiO 2 / Cr / Si 3 N 4 Solar control coated glass with three-layer structure, the functional layer Cr is not resistant to acid corrosion, and the surface layer Si 3 N 4 The film is not resistant to alkali corrosion; and glass / TiO 2 / ZnO x / Cu / NiCr / Si 3 N 4 The coated glass of equal film system also has the same disadvantages

Since the current solar control coated glass has the disadvantages of poor acid and alkali resistance and salt spray corrosion resistance and poor scratch resistance of the surface protection layer, the general coated glass needs to be reprocessed into hollow glass, and the film layer is on the side of the hollow cavity. This can improve the thermal insulation performance of the glass and at the same time protect the film layer
