Detailed Description

Referring to fig. 1, there are shown an inner glass i 1 facing an interior of a building in a use state and an outer glass ii 2 facing an exterior of the building in a use state, the inner glass i 1 and the outer glass ii 2 being disposed to face each other.

As the technical scheme provided by the utility model: a sound absorbing plate 3 and a color changing film 4 are arranged between the inner glass I1 and the outer glass II 2, the sound absorbing plate 3 is arranged between the inner glass I1 and the color changing film 4, the color changing film 4 is arranged between the sound absorbing plate 3 and the outer glass II 2, and honeycomb-shaped sound absorbing holes 31 are formed on the sound absorbing plate 3 in a dense state, the honeycomb-shaped sound absorbing holes 31 are blind holes with openings facing to one side of the outer glass II 2, wherein one side of the sound absorbing plate 3 facing to the inner glass I1 is bonded with one side of the inner glass I1 facing to the outer glass II 2 through a first adhesive layer I32, one side of the sound absorbing plate 3 facing to the color changing film 4 is bonded with the color changing film 4 through a second adhesive layer II 33, the color changing film 4 is bonded with one side of the outer glass II 2 facing to the inner glass I1 through a third adhesive layer III 41, the inner glass I1 is transparent flat glass, the outer glass II 2 is toughened glass, the sound-absorbing plate 3 is a transparent glass plate with the thickness of 5mm, and the gram weight of the color-changing film 4 is preferably 200-300g/m²Preferably 240-280 g/m²Preferably 260 g/m²The PVB temperature-sensitive color-changing film of (1) may be an EVA temperature-sensitive color-changing film.
