The invention discloses multi-cavity nano-composite energy-saving sheet material middle-positioned glass, which comprises two layers of transparent glass plates, at least one layer of transparent nano-composite sheet material containing core-shell structure double-function nano-particles with ultraviolet shielding and infrared ray blocking performances and a spacing bar; arranging a composite sheet between two layers of glass plates, arranging spacing strips between the glass plates and the peripheral outer edges of the composite sheet, dividing the interior of the two layers of glass plates into a plurality of cavities by transparent nano composite sheets, and filling gas into the cavities; the joint of the spacing strip, the glass plate and the composite sheet is sealed and fixed through sealant. The invention also discloses a preparation method of the middle glass. The built-in glass has good daylighting performance, can effectively block heat radiation and heat conduction, can also effectively block ultraviolet radiation in sunlight, and can furthest play the role of heat insulation of the multi-cavity glass, thereby achieving better energy-saving effect. |
