Description
Technical Field
The invention relates to the technical field of glass production, in particular to coated glass with high transmittance and capable of being used in a single piece.
Background
The low-emissivity coated glass with the best performance and highest market share sold in the market at present comprises at least one silver type metal functional layer, wherein the silver type metal functional layer mainly has the function of enabling most of incident IR (infrared) radiation to be reflected back to a radiation source side, for example, the low-emissivity coated glass can block outdoor solar radiation energy from entering a room in summer so as to reduce the use cost of an air conditioner; the indoor heating air can be prevented from flowing to the outside through the glass in winter, so that the heating cost is reduced. Thereby playing the role of energy conservation and environmental protection. However, such film layers are very susceptible to oxidation, sulfidation, etc., resulting in the necessity of using the film side of such silver-based low emissivity coated glass for the hollow interior side of the hollow glass to avoid damage upon exposure to air.
In current solar control single layer glasses with niobium as the functional layer, the only niobium functional layer is deposited on a separate glass substrate. The value of the heat transfer coefficient U specified by the current standards of the country can be satisfied only when the thickness of the functional layer of such a product is relatively thick (for example, about at least 10 nm or more). But when the functional layer is thicker, it is non-selectively absorbing due to the exposure to the incident radiant energy, resulting in a very low light transmittance (typically less than 30% and even less than 20%) of such glasses.
In view of such characteristics, it has been difficult for existing products to obtain from such film layers while having an acceptable heat transfer coefficient U, and while maintaining a sufficiently high (light transmission greater than 40%, preferably greater than 50%) solar light transmission.
Disclosure of Invention
The invention provides coated glass with high transmittance and single sheet use, which can solve the problem of lower transmittance while ensuring low enough heat transfer coefficient.
In order to achieve the above purpose, the invention adopts the following technical scheme: the utility model provides a coated glass that high transmissivity can monolithic use, includes the glass base member and plates and locate the compound rete of glass base member one side surface, compound rete is including from the outwards first anti-reflection dielectric rete, first high temperature resistant fire-retardant rete, first metal isolation rete, first functional rete, second metal isolation rete, second anti-reflection dielectric rete, second high temperature resistant fire-retardant rete, third metal isolation rete, second functional rete, fourth metal isolation rete and the protective dielectric rete of depositing in proper order of glass base member.
Further, the first functional film layer and the second functional film layer are metal niobium layers or niobium nitride layers.
Further, the first functional film layer is 15-60nm; the second functional film layer is 20-60nm.
Further, the first anti-reflection dielectric film layer/the second anti-reflection dielectric film layer is any one or a composite layer of two of a ZnSnOx layer and a ZnSnOx layer.
Further, the thickness of the first anti-reflection dielectric film layer is 20-100nm; the thickness of the second anti-reflection dielectric film layer is 30-90nm.
Further, the first high-temperature-resistant flame-retardant film layer/the second high-temperature-resistant flame-retardant film layer is an SbOx layer.
Further, the thickness of the first high-temperature-resistant flame-retardant film layer is 25-55nm; the thickness of the second high-temperature-resistant flame-retardant film layer is 20-50nm.
Further, the first metal isolating film layer/the second metal isolating film layer/the third metal isolating film layer/the fourth metal isolating film layer is any one or any multiple composite layers of a NiCrOx layer, a NiCr layer, a Ti layer and a TiOx layer.
Further, the thickness of the first metal isolation film layer is 0.5-5nm; the thickness of the second metal isolation film layer is 0.5-6nm; the thickness of the third metal isolation film layer is 0.5-5nm; the thickness of the fourth metal isolation film layer is 0.5-6nm.
Further, the protective dielectric film layer is any one layer or any two layers of a SiNx layer, a SiOx layer, a SiNxOy layer and a TiOx layer, and the thickness of the protective dielectric film layer is 20-60nm.
After the technical scheme is adopted, compared with the prior art, the invention has the following advantages:
1. the glass product provided by the invention has the effects of low heat transfer coefficient and high light transmittance by optimizing the structure and thickness parameters of the composite film layer, and has lower emissivity and higher selection coefficient compared with coated glass with a single functional film layer.
2.

3. The first anti-reflection dielectric film layer and the second anti-reflection dielectric film layer have higher refractive indexes to offset the absorption of the first functional film layer and the second functional film layer, so that the light transmittance of the glass product can reach 40% or more, the appearance of the glass product is clear and transparent, good heat insulation and heat preservation effects can be ensured, and the glass product meets the requirement of consumers for pursuing natural environment protection.
4. According to the invention, the flame-retardant material antimony oxide is used as a coating material, so that the high-temperature impact resistance of the coating is improved, and the problem of multiple appearance defects of the toughened glass product is solved.

Particularly, when the first metal isolation film 203/the second metal isolation film 205/the third metal isolation film 208/the fourth metal isolation film 210 include a NiCrOx layer, the NiCrOx layer has a better affinity for oxygen that partially permeates during the heating process, so that oxygen molecules are effectively captured, and the first functional film 204 and the second functional film 209 can be better protected.
