Definitions
- the present invention relates to a multilayer glass having a dimming function.
- multilayer glass As for the window glass for railway vehicles, in order to improve sound insulation, heat insulation, and safety, multilayer glass is generally used (see Patent Document 1, etc.).
- This multilayer glass is configured by separating an outdoor glass plate and an indoor glass plate via a spacer and sealing a peripheral edge portion with a sealing material.
- a non-reinforced glass plate (float glass) having a thickness of 5 mm is used as the outdoor glass plate and the indoor glass plate.
- the strength of the multilayer glass is set to a strength suitable for a window glass for a railway vehicle.
- the outdoor glass plate of the double-glazed glass of Patent Document 1 is provided with a self-dimming film.
- This self-light-modulating film is formed by sputtering on the surface facing the indoor glass plate among the two surfaces of the outdoor glass plate. According to this self-modulating film, when the intensity of light from the outside is low, the visible light transmittance is 70 to 90%, and when the intensity of light from the outside is high, the visible light is transmitted. It has a function to make the rate 50-70%.
- the double-glazed glass of Patent Document 1 uses two non-tempered glass plates having a thickness of 5 mm in order to give strength suitable for a window glass for a railway vehicle. Thereby, there existed a problem that the multilayer glass of patent document 1 became heavy.
- the strength of the glass means the resistance to breakage when subjected to an impact by an external force
- the strength is a three-point bending test according to “JIS R 1601 Bending strength test method of fine ceramics”
- it can be measured by a 4-point bending test.
- the double-glazed glass of Patent Document 1 has a problem that the sun light transmitted through the outdoor glass plate is directly incident on the self-light control film, so that the temperature of the self-light control film is increased by the heat of sunlight.
- the temperature of the outdoor glass plate is raised to nearly 80 to 100 degrees, and if left in this state for a long time, there is a problem that the performance of the self-light control film deteriorates.
- the SPD In a light control sheet that is not a self light control film but changes the light transmittance by voltage application, for example, a suspended particle device (hereinafter referred to as SPD (Suspended Particle Device)), the SPD has an upper endurance upper limit temperature of 90 to 100 degrees. Therefore, there is a risk that the performance is deteriorated early.
- SPD suspended Particle Device
- the present invention has been made in view of such circumstances, and is a multilayer glass having a light control function capable of reducing the weight while maintaining the strength and ensuring the performance of the light control sheet over a long period of time.
- the purpose is to provide.
- the outdoor laminated glass arranged on the outdoor side and the indoor laminated glass arranged on the indoor side have spacers.
- Each side surface of the spacer that is spaced through and opposed to the outdoor side laminated glass and the indoor side laminated glass is bonded to the outdoor side laminated glass and the indoor side laminated glass by a primary sealing material, and
- the outdoor laminated glass includes a first chemically strengthened glass plate, a first intermediate film, and a second chemically strengthened glass plate.
- the indoor laminated glass includes a glass plate, a second intermediate film, a light control sheet, and a front plate on which a heat ray reflective film is formed.
- a multilayer glass comprising a third intermediate film, a fourth intermediate film, and a tempered glass plate surrounding the light control sheet, which are arranged from the outdoor side toward the indoor side. I will provide a.
- the outdoor laminated glass is constituted by the first chemically strengthened glass plate, the first intermediate film, and the second chemically strengthened glass plate.
- the indoor side laminated glass is constituted by the non-tempered glass plate, the second intermediate film, the light control sheet, the third intermediate film, the fourth intermediate film, and the tempered glass plate.
- the indoor side laminated glass of the present invention can obtain the same strength as the conventional indoor side glass plate even if the thickness thereof is reduced as compared with the indoor side glass plate which is a conventional non-tempered glass plate. .
- weight reduction can be achieved while maintaining strength.
- the light control sheet is interposed between the second intermediate film and the fourth intermediate film, and the light control sheet is surrounded by the third intermediate film at the peripheral edge thereof.
- the light control sheet of a delicate structure can be protected reliably.
- the heat ray reflective film is formed on the glass plate, the light control sheet can be protected from the heat of sunlight.
- the performance of the light control sheet can be guaranteed over a long period of time.
- the glass plate (glass plate in which a heat ray reflective film is formed) arrange
- positioned at an outdoor side in the above-mentioned indoor side laminated glass is a non-tempered glass plate.
- an outdoor laminated glass arranged on the outdoor side and an indoor laminated glass arranged on the indoor side have spacers.
- Each side surface of the spacer that is spaced through and opposed to the outdoor side laminated glass and the indoor side laminated glass is bonded to the outdoor side laminated glass and the indoor side laminated glass by a primary sealing material, and
- the outdoor laminated glass includes a first chemically strengthened glass plate, a first intermediate film, and a second chemically strengthened glass plate.
- the indoor side laminated glass includes a glass plate, a second intermediate film, a heat ray reflective sheet, a third intermediate film, a light control sheet,
- a multilayer glass characterized in that the fourth interlayer film, the fifth interlayer film, and the tempered glass plate surrounding the light sheet are configured as a laminated glass arranged from the outdoor side toward the indoor side.
- One aspect of the present invention is a form in which a heat ray reflective sheet is used instead of the heat ray reflective film.
- the glass plate disposed on the outdoor side of the indoor laminated glass is not limited to the non-tempered glass plate and may be a tempered glass plate.
- the heat ray reflective sheet is interposed between the second intermediate film and the third intermediate film, the heat ray reflective sheet is protected by the second intermediate film and the third intermediate film.
- the light control sheet is interposed between the third intermediate film and the fifth intermediate film, and the light control sheet is surrounded by the fourth intermediate film at the peripheral portion thereof, the light control sheet is The intermediate film, the fourth intermediate film, and the fifth intermediate film are protected.
- the second intermediate film, the third intermediate film, and the fourth intermediate film are ethylene vinyl acetate copolymers. .
- the second intermediate film, the third intermediate film, the fourth intermediate film, and the fifth intermediate film are made of ethylene vinyl acetate.
- a polymer is preferred.

・複層ガラス10の質量:10.3kg(スペーサ16を除く)。
以上の如く、実施形態の複層ガラス10によれば、従来の複層ガラスと比較して、強度を保持しつつ、ガラス板の質量として約26.5%の軽量化を図ることができた。
図4は、第2の実施形態の複層ガラス50の断面図である。図5は、図4に示した複層ガラス50を構成する各部材を離間して示した複層ガラス50の組み立て斜視図である。図6は、複層ガラス50を構成する各部材を離間して示した複層ガラス50の縦断面図である。
第2の実施形態の複層ガラス50の場合、ガラス板32には熱線反射膜が形成されないので、ガラス板32としては、非強化ガラス板であってもよく、また強化ガラス板(特には、板厚をより薄くできる点から化学強化ガラス板)であってもよい。
熱線反射シート52としては、PET等の透明シートの表面に、赤外線を反射する透明の熱線反射層(例えば、銀等の金属層)が形成されたシートを例示できるが、これに限定されるものではない。
