Embodiment 1

[0050] Such as figure 1 The smart dimming glass shown has a structure of a first glass layer 1 , a smart dimming layer 2 , an adhesive layer 3 , and a second glass layer 4 . Both the first glass layer 1 and the second glass layer 4 are 2mm ordinary non-stress strengthened transparent soda lime glass. The adhesive layer 3 is 0.76mm PVB. The intelligent dimming layer 2 is composed of a vanadium oxide material with phase change properties coated on a 30 μm thick PET substrate. The side of the intelligent dimming layer 2 coated with the vanadium oxide material is the same as the first The opposite side of the glass layer 1 is adhesive.

[0051] The manufacturing process of the laminated glass in this embodiment is as follows: place the first glass layer 1, attach the side of the intelligent dimming layer 2 coated with vanadium oxide material on the first glass layer 1, and lay the PVB adhesive layer 3 , to place the second glass layer. After being stacked in the above order, pre...

Embodiment 2

[0053] Compared with Example 1, the difference is that the vanadium oxide material in the intelligent dimming layer material is doped with W element at a concentration of 0.7 mol%, and the first glass layer and the second glass layer are respectively 6mm thick Green soda-lime tempered glass, doped vanadium oxide material is coated on a PET substrate with a thickness of 75 μm; after stacking each layer neatly in sequence, the laminated glass composite after preheating and rolling is sent into the autoclave 130 ℃, 1.3Mpa environment for 2 hours. The phase transition temperature of the laminated glass product in this example is 44°C.

Embodiment 3

[0055] Compared with Example 2, the difference is that the vanadium oxide material is doped with 0.6 mol% W and 0.8 mol% Mo, and the first glass layer and the second glass layer are 8mm thick transparent soda calcium Curved glass, doped vanadium oxide material is coated on a 100μm transparent PI substrate; after stacking each layer neatly in sequence, after vacuuming and pre-pressing edge sealing agent, it is sent to an autoclave at 140°C and 1.0Mpa for heat preservation 1.5 hours. In this embodiment, the phase transition temperature of the intelligent dimming layer in the laminated glass product is 39.5°C, and when the intelligent dimming layer (or laminated glass) reaches 50°C, the transmission adjustment rate at 1500nm reaches complete phase transition transparency. 87% of the over-regulation rate.

Abstract

The invention provides an intelligent light-adjusting energy-saving laminated glass and a preparation method thereof. The intelligent light-adjusting energy-saving laminated glass comprises a first glass layer and a second glass layer. At least one group of adhesive layer and intelligent light-adjusting layer composite structure is arranged between the first glass layer and the second glass layer; the intelligent light-adjusting layer is a film with phase transformation function to adjust solar or infrared radiation along with the variation of temperature; the intelligent light-adjusting layer is formed by compounding a vanadium oxide composite material with phase transition character on a flexible substrate; one side compounded with vanadium oxide material of the flexible substrate has adhesive property, and the other side of the flexible substrate has no adhesive property; and the adhesive layer is pasted on the side without adhesive property of the flexible substrate. The laminated glass has the advantages of simple preparation, low cost, high yield, and good adjustment effect of infrared radiation.

Description

technical field [0001] The invention relates to the field of building energy saving, in particular to a laminated glass with intelligent dimming function. Background technique [0002] The structure of laminated glass is usually a resin film sandwiched between two inorganic glass plates, and the resin film plays the role of bonding the two inorganic glass plates. Compared with ordinary single-piece glass, laminated glass has superior impact resistance, and glass damage is not easy to cause personal injury. Therefore, laminated glass is used as window glass that requires a sense of security or safety. Combined with various resin films, laminated glass can realize the superior performance of reducing noise and improving heat insulation effect of glass composites. Laminated glass has many advantages as mentioned above, so it is widely used in automobiles, airplanes, rail trains, and building doors and windows. [0003] Common laminated glass is formed by bonding two pieces o...
