Problems solved by technology

However, if the film is thin, the annealing time will be prolonged under the same conditions, resulting in a decrease in the effective absorption rate of the film for radiation rays, and the thinner the film is, the longer it will take to reach the annealing temperature for crystallization

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 a thermochromic intelligent dimming energy-saving glass, a thermochromic intelligent dimming energy-saving glass, which is characterized in that it comprises a first glass layer, a frame, and a glass composite that are laminated in sequence, and the first glass layer passes through the frame and the glass composite. The glass composite body is bonded to form a hollow glass structure; the glass composite body is selected from a single-layer glass or a laminated glass structure; the glass composite body contains a thermochromic intelligent film layer with a phase change function. The invention realizes heat regulation along with the change of ambient temperature, and can be widely used in the fields of energy-saving doors and windows of buildings and doors and windows of vehicles and ships. Its structure can increase the safety performance of the glass such as impact resistance, and prolong the service life of the vanadium oxide composite film layer. Secondly, the selection of various substrate materials can meet the needs of glass strength in different environments.

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...
