Nanometer ceramic intermediate film laminated hollow glass and manufacturing method thereof

Abstract

The invention relates to the technical field of automobile and building energy saving glass and discloses nanometer ceramic intermediate film laminated hollow glass and a manufacturing method thereof. The nanometer ceramic intermediate film laminated hollow glass comprises a first glass layer, a second glass layer, a composite tungsten oxide nano-ceramic dispersion liquid-doped modified PVB intermediate film sandwiched between the first and second glass layers and a third glass layer arranged at one side of the second glass layer. The second glass layer and the third glass layer are bonded and sealed through a hollow glass spacing bar so that a hollow layer is formed. The third glass layer is Low-E glass and the Low-E glass faces to the second glass layer. The nano-ceramic-modified PVB intermediate film has high obstruction effects on infrared ray and ultraviolet ray. The Low-E hollow glass in the third layer greatly reduces a glass shading coefficient and a heat transfer coefficient, improves a photo-thermal ratio and comfortableness, improves summer heat insulation and insulation efficiency, reduces air-conditioning energy consumption and has good energy saving effects.

Description

technical field [0001] The invention relates to the technical field of automobile front windshield and building energy-saving glass, in particular to a nano-ceramic interlayer interlayer hollow glass and a manufacturing method thereof. Background technique [0002] Generally, in the windshield used in automobiles, or the glass used in architectural glass curtain walls, laminated glass is made by sandwiching an interlayer between two glass plates, such as PVB film, EVA film, etc., using the transparency and adhesion of the interlayer film structure. It improves the penetration resistance of the glass, and at the same time, when the glass receives an external impact, the broken glass fragments are attached to the transparent adhesive layer to prevent it from splashing and improve the safety performance of the glass. However, the thermal insulation performance of the current PVB film and EVA film is poor, and the thermal insulation performance of the prepared laminated glass ca...

AI Technical Summary

Problems solved by technology

[0009] 1) While reducing Sc, the transmittance of visible light is reduced, resulting in dark window glass, insufficient indoor lighting, and increased power consumption due to more time spent indoor lighting;

[0010] 2) In order to increase the heat insulation effect, it is necessary to increase the reflection of the near-infrared region, and the near-infrared region and the visible light border at a wavelength of 780nm, so that part of the reflection enters the visible light region, thus increasing the reflection of visible light and causing urban light pollution;

Due to the weak and heat reflection characteristics of the off-line Low-E film layer, the production difficulty of laminated glass is increased;

[0012] 4) In order to improve visible light transmission and reduce near-infrared transmission, it is necessary to use double-silver or expensive triple-silver sunshade offline Low-E glass, which increases the cost of materials

[0013] 5) Low-E, especially the Low-E glass with double or triple coating (commonly known as double silver and triple silver), has greater shielding of electromagnetic waves, which makes the signals of mobile phones and Wi-Fi entering the car and indoors relatively weak. Weak, affecting communication function
