Embodiment 1

[0073] combine figure 1 As mentioned above, the structure of the energy-saving glass in this embodiment is as follows: the first glass layer (10mm physically tempered glass substrate), the frame (and sealant) filled with molecular sieves, the second glass layer (4mm physically tempered glass substrate), Film (0.76mm transparent PVB), thermochromic smart film layer (located on the side of the third glass layer facing the film), third glass layer (4mm physically tempered glass substrate).

[0074] The preparation method is as follows:

[0075] (1) A glass substrate is provided. Physically toughen two pieces of 4mm ordinary float glass to form a glass substrate with a surface stress of 100MPa (respectively the second glass layer and the third glass layer), and physically toughen a piece of 10mm ordinary float glass to form a glass substrate with a surface stress of 100MPa sheet (first glass layer).

[0076] (2) Deposit the film layer. G / SixNy(30nm) / VOx(120nm) / SixNy(150nm) is ...

Embodiment 2

[0083] Compared with Example 1, the difference is that the second and third glass layers are 4mm semi-tempered glass substrates, the first glass layer is a 5mm physically tempered glass substrate, and the thermochromic intelligent film layer is deposited on the second glass layer On the surface of the substrate, the deposited film structure is G / ITO (150nm) / VOx (150nm) / SixNy (50nm). x=2.15 of VOx, where x is the average number of atoms. Annealing time 55s. In the process of preparing the interlayer, the third glass layer, 0.76mmPVB, and the second coated glass layer are stacked in sequence, and the film surface is located on the top (that is, the last thermochromatic intelligent film layer is located on the side of the sealed hollow cavity). Then adopt vacuum method to carry out high-temperature and high-pressure molding to form a glass composite body.

Embodiment 3

[0085]Compared with Example 1, the difference is that the second and third glass layers are common 4mm float glass, and the thermochromatic intelligent film layer is deposited on the second glass layer substrate surface, and the film layer structure is G / SixNy (80nm ) / NiCrOx(1nm) / VOx(30nm) / NiCrOx(15nm) / SixNy(150nm). In VOx, x=1.75, where x is the average number of atoms. Annealing time 135s. In the process of preparing the interlayer, the third glass layer, 0.76mm PVB, and the second coated glass layer are stacked in sequence. The film surface is adjacent to the PVB film, and then the glass composite is formed by high temperature and high pressure forming by rolling. The thermochromatic intelligent film layer is located in the second The second glass layer faces the side of the film.

Abstract

The invention relates to intelligent heat-color light-dimming energy-saving glass. The intelligent heat-color light-dimming energy-saving glass is characterized by comprising a first glass layer, a frame and a glass complex which are adhered in sequence, wherein the first glass layer is boned with the glass complex through the frame to form a hollow glass structure. The glass complex is selected from single-layer glass or interlayer glass structures. The glass complex comprises an intelligent heat-color film layer having a phase-change function. The intelligent heat-color light-dimming energy-saving glass achieves heat adjustment with environment temperature change and can be widely applied to the field of building energy-saving door windows and vehicle and ship windows. By the adoption of the structure, impact resistance and other safety properties of the glass can be improved, the service life of a vanadium oxide composite film layer can be prolonged, and the demands for different environmental glass strength can be met by selecting multiple substrate materials.

Description

technical field [0001] The invention relates to an energy-saving glass capable of adjusting heat as the ambient temperature changes and a preparation method thereof, which can be widely used in the fields of building energy-saving doors and windows and vehicle and ship doors and windows. Background technique: [0002] Insulating glass is composed of two or more layers of flat glass. A high-strength and high-air-tight composite adhesive is used around, and two or more pieces of glass are bonded and sealed through the frame through the sealant. The middle is filled with dry gas, and the frame is filled with desiccant to ensure the dryness of the air between the glass sheets. It is a building material with good heat insulation, sound insulation, aesthetics and applicability, and can reduce the weight of buildings. It is mainly used in buildings that require heating, air conditioning, noise or condensation prevention, and buildings that require no direct sunlight and special l...
