Description

Technical Field

[0001] This utility model relates to the field of low-emissivity coated glass technology, and in particular to a light blue double-silver low-emissivity coated glass with a yellow-green two-tone color scheme. Background Technology

[0002] Low-emissivity (Low-E) glass is a product made by coating a glass surface with multiple layers of metal or other compounds, including a silver layer. Due to the low emissivity of the silver layer, LOW glass has high transmittance for visible light and high reflectivity for infrared radiation, resulting in excellent heat insulation performance. Double-silver LOW glass adds a silver film layer to ordinary single-silver LOW glass. Compared to single-silver LOW glass, double-silver LOW glass maintains high transmittance for visible light while having even higher reflectivity for infrared radiation, providing even stronger heat insulation performance.

[0003] The film structure of double-silver low-emissivity coated glass produced by vacuum magnetron sputtering is generally as follows: glass / base dielectric layer / first functional silver layer / first barrier layer / intermediate dielectric layer / second functional silver layer / second barrier layer / top dielectric layer, etc. The dielectric layer is generally a metal oxide or metal nitride, or a non-metal oxide or non-metal nitride, such as SiZrOx, TiO2, ZnSnOx, SnO2, ZnO, SiO2, Ta2O5, SiNxOy, BiO2, Al2O3, Nb2O5, Si3N4, AZO, etc. The first and second barrier layers are generally metals or metal oxides (nitrides), or alloys or alloy oxides (nitrides), such as Ti, NiCr, or NiCrOx, NiCrNx, etc.

[0004] However, in the development and production of traditional double-silver low-emissivity films, most common products are blue-gray, silver-blue, gold, green, red, and purple, while high-performance double-silver products in a light blue color with a yellow-green hue are rare. For example, patent CN218710007U discloses a temperable purple double-silver low-emissivity coated glass, which includes a glass substrate. On one side of the glass substrate, from the inside out, there are sequentially arranged a base dielectric layer, a base second dielectric layer, a first functional silver layer, a first barrier layer, an intermediate dielectric layer, a second barrier layer, a second functional silver layer, a third barrier layer, an upper dielectric layer, an upper second dielectric layer, and an outer protective layer; its appearance can achieve an elegant purple effect.

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0026] like Figure 1 and Figure 2 As shown, this light blue double-silver low-emissivity coated glass with a yellow-green two-tone finish includes a glass substrate. On one side of the glass substrate, from the inside out, are sequentially arranged a base dielectric layer, a base second dielectric layer, a first barrier layer, a first functional silver layer, a first dielectric protective layer, an intermediate dielectric layer, an intermediate third dielectric layer, a second functional silver layer, a second barrier layer, an upper dielectric protective layer, an upper second dielectric layer, and an outer protective layer. The light blue double-silver low-emissivity coated glass with a yellow-green two-tone finish provided by this invention achieves a natural light blue effect, with a slightly yellowish film surface and a reflective color consistent with light green. Its color is natural, and the color range can be flexibly adjusted. This invention can obtain multiple varieties of near-light blue double-silver low-emissivity coated glass with different shading coefficients and emissivity by changing the thickness of each film layer, filling the gap in the double-silver market for light blue yellow-green two-tone products and meeting diverse market demands.

[0027] Furthermore, the thickness of the base dielectric layer is 20-30 nm, the thickness of the base second dielectric layer is 8-10 nm, the thickness of the intermediate dielectric layer is 66-70 nm, the thickness of the intermediate third dielectric layer is 8-10 nm, the thickness of the upper second dielectric layer is 25-30 nm, the thickness of the outer protective layer is 2-5 nm, the thickness of the first functional silver layer is 8-8.5 nm, the thickness of the second functional silver layer is 11-14 nm, the single-layer thickness of the first barrier layer is 2-3 nm, the single-layer thickness of the second barrier layer is 3.5-4.5 nm, the thickness of the first dielectric protective layer is 8-10 nm, and the thickness of the upper dielectric layer is 5-7 nm.

[0028] The base dielectric layer is a non-metallic nitride film. The base second dielectric layer is a metal oxide film. The first dielectric protective layer is a metal oxide film. The intermediate dielectric layer is a metal oxide film. The intermediate third dielectric layer is a metal oxide film. The upper dielectric protective layer is a metal oxide film. The upper dielectric layer is a metal oxide film. The upper second dielectric layer is a non-metallic nitride film; the outer protective layer is a non-metallic oxide film. Both the first and second barrier layers are films made of one of the following materials: nickel-chromium, nickel-chromium oxide, or nickel-chromium nitride.

[0029] This patented light blue double-silver low-emissivity coated glass features a reasonable design with a yellow-green dual-tone color. The glass surface and color cast are both light blue, while the coating has a yellowish-green tint, bringing a dark-toned glass product to the market, making the building structure appear more stable and elegant. It has low emissivity (between 0.03 and 0.04), a light blue glass surface color (a value 0.7, b value -14.1, transmittance 59.5%), and is very practical in both performance and appearance, making it suitable for use in civil buildings.

[0030] From the inside out, each layer works in close collaboration and orderly sequence: the base dielectric layer and the second base dielectric layer, as the crucial transition, not only achieve molecular-level tight adhesion with the glass substrate, ensuring the film remains stable during long-term use, but also act as a smart buffer, effectively dispersing the internal stress generated by the entire low-emissivity film under complex environments, laying a solid foundation for the stable operation of subsequent layers. The subsequent barrier layer, functional silver layer, dielectric protective layer, and intermediate dielectric layer work together to construct a powerful system integrating heat insulation, light modulation, and protection. The meticulously designed upper dielectric protective layer, upper second dielectric layer, and outer protective layer provide the ultimate guarantee for the product's durability and stability. Among these, the precise locking of the base dielectric layer thickness within the golden range of 20-30nm is the key to achieving its superior performance.

[0031] Its exterior presents a stunning natural light blue, as clear as the first rain after a clear day, with a subtle hint of pale yellow on the membrane surface, infusing the cool blue with warmth and softness. The reflected color is a refreshing and pleasant light green, like tender spring leaves, adding a touch of vitality to the building's appearance. The three colors intertwine yet do not interfere with each other, creating a harmonious, natural, and highly sophisticated visual effect. Whether viewed from afar or up close, it brings a pleasant and unique aesthetic experience, instantly elevating the building's style and taste.

[0032] The greatest advantage of this invention lies in its flexible and versatile color control. Thanks to its unique film layer design and innovative process, by precisely adjusting the thickness of each film layer, it is like operating a precision color palette, enabling free switching between a light, misty blue and a deep, rich azure blue, while also accurately controlling the intensity of secondary colors such as pale yellow and light green.

[0033] Through precise control of the thickness of each film layer, especially the accurate deposition of the two functional silver layers, this glass can be used to create a rich product series with different shading coefficients and emissivity. In the sweltering summer, products with high shading coefficients can effectively block over 80% of solar radiation heat, significantly reducing indoor air conditioning energy consumption and creating a cool and comfortable indoor environment. In the cold winter, the low emissivity minimizes heat loss, reducing heating costs and achieving high energy efficiency. Whether in the frigid north or the scorching south, the most suitable product can be selected based on local climate conditions, truly achieving localized solutions.

[0034] The meticulously designed multi-layered protective coating endows the product with exceptional durability. The upper dielectric layer, with its superior oxidation resistance, effectively protects against natural erosion such as ultraviolet rays and acid rain. The upper second dielectric layer provides excellent flexibility and impact resistance, making it resistant to breakage even from external impacts. The outer protective layer offers top-tier scratch and abrasion resistance with its ultra-high hardness, ensuring the glass surface remains pristine for a long time. This series of protective measures extends the product's lifespan by more than 30% compared to traditional double-silver low-emissivity coated glass, significantly reducing building maintenance costs.

[0035] In the fiercely competitive market for double-silver low-emissivity coated glass, product colors have long been monopolized by traditional color schemes, leaving a void in the market for light blue products with a yellow-green hue. The emergence of this invention, like a shining new star, successfully fills this market gap and greatly enriches the product portfolio of double-silver low-emissivity coated glass.

[0059] The glass colors in the above embodiments are shown in Table 1:

[0060]

[0061] The meanings of each letter in Table 1 are as follows:

[0062] G represents the glass surface of the coated glass; R*g represents the reflectance value of the glass surface of the coated glass; a*g and b*g represent the color values ​​of the glass surface of the coated glass, the more positive a*g is, the redder the color, the more negative a*g is, the greener the color, the more positive b*g is, the yellower the color, the more negative b*g is, the bluer the color; L*g represents the brightness of the glass surface of the coated glass.

[0063] F represents the coating surface of the coated glass; R*f represents the reflectance value of the coating surface of the coated glass; a*f and b*f represent the color values ​​of the coating surface of the coated glass, the more positive a*f is, the redder the color, the more negative a*f is, the greener the color; the more positive b*f is, the yellower the color, the more negative b*f is, the bluer the color; L*f represents the brightness of the coating surface of the coated glass.

[0064] T represents the transmittance of the coated glass; Tr represents the transmittance of the coated glass; a*T and b*T represent the color values ​​transmitted by the coated glass, the more positive a*T is, the redder the color, the more negative a*T is, the greener the color; the more positive b*T is, the yellower the color, the more negative b*T is, the bluer the color; L*T represents the brightness transmitted by the coated glass.

[0065] As can be seen from Table 1 above, the double silver low-emissivity coated glass in each embodiment is light blue, the emissivity can be controlled between 0.03 and 0.04, the glass surface color is light blue, the reflectivity Y value ranges from 6.0 to 7.0, the a* value ranges from 0.0 to 1.0, the b* value ranges from -13.5 to -14.5, and the transmittance is between 59% and 62%.

[0066] The features of the yellow-green two-tone light blue double silver low-emissivity coated glass and its manufacturing process provided by this utility model are as follows:

[0067] 1. Treatment of the film layers in this utility model. The base dielectric layer and the base second dielectric layer are anti-reflective film layers, which serve to connect the glass and the functional layers. Good adhesion between the film layers and the glass is required, and the internal stress of the entire low-emissivity film must be alleviated. The intermediate dielectric layer and the first dielectric protective layer protect the first and second silver layers and can adjust the polarization color. Different degrees of light blue polarization effects can be obtained by adjusting their thickness. The upper three dielectric layers directly affect the product's scratch resistance, wear resistance, oxidation resistance, and corrosion resistance. Oxidation resistance is mainly addressed by the upper dielectric layer, toughness by the upper second dielectric layer, and scratch resistance, wear resistance, and corrosion resistance mainly by the upper third dielectric layer.

[0068] 2. Our yellow-green two-tone light blue double-silver low-emissivity coated glass features a modified thickness ratio between the base dielectric layer and the second dielectric layer, enhancing color adjustability and incorporating a new material as the upper third dielectric layer. The selected material possesses high inherent hardness and is deposited onto the outermost layer via magnetron sputtering, further strengthening the film's hardness. This enhances the film's scratch and abrasion resistance, providing significant advantages in post-processing. It facilitates off-site processing of the double-silver coating, reduces defective product losses, lowers costs, and increases profits.

[0069] 3. By controlling the deposition thickness of the two functional silver layers, the emissivity of the glass is effectively reduced to between 0.03 and 0.04. This ensures excellent thermal insulation performance, aligning better with current green, environmentally friendly, and energy-saving concepts, and contributing more effectively to energy conservation and emission reduction.

[0070] 4. By coordinating the dielectric layer, dielectric protective layer, silver film layer, and barrier layer, and controlling the thickness of each film layer, a light blue double-silver low-emissivity film with a yellow-green dual-tone is deposited. In the current market for double-silver low-emissivity coated glass, most common products are blue-gray, silver-blue, gold, green, red, and purple, while light blue double-silver products with a yellow-green dual-tone are rare. This invention fills this market gap and expands the range of options for double-silver low-emissivity coated glass.

[0071] The above description is only a preferred embodiment of the present utility model. The above technical features can be arbitrarily combined to form multiple embodiments of the present utility model.

[0072] The present invention has been described above with reference to the accompanying drawings.
