Insulation Multilayer glass

The present invention relates to a heat insulating multilayer glass, and more specifically, to a heat insulating member of a semi-solid permeable material between the first transparent plate and the opposite inner surface of the second transparent plate in close contact with the first transparent plate and the second transparent plate. It has a superior heat insulation and sound insulation effect between the first transparent plate and the second transparent plate than the heat insulating multilayer glass filling air and scarce gas, and the first transparent plate and the second transparent plate are closely adhered to each other through a semi-solid heat insulating member. It relates to a safe insulating double-layer glass that prevents the glass pieces from scattering when the first transparent plate or the second transparent plate breaks.

Due to rising international oil prices and global warming, many researches and investments are being made on eco-friendly building technology and materials that can save energy along with developing new alternative energy. In buildings such as houses and buildings, a large amount of energy is consumed by heating and cooling. In order to increase the efficiency of heating and cooling, heat insulating walls and window panes for influencing heat insulation and airtightness of buildings are being developed.

In general, however, the insulating glazing is low in insulation because of its high heat penetration rate as compared with the insulating wall material. Therefore, in order to save energy in buildings, it is important to develop insulation window glass having a heat penetration rate almost similar to that of insulation wall materials.

Referring to FIG. 7, the heat insulation member 230 is disposed in the inner space generated in a state in which the spacer portion 240 having the thickness of 6 mm is attached to the second glass plate 220 having the thickness of 6 mm. . The heat insulating member 230 is formed by curing 40 wt% of a curing material in 100 wt% of polypropylene glycol (PPG) and curing for 30 minutes at room temperature. The insulation member solution is directly added to the created inner space and cured at room temperature for 30 minutes to generate the insulation member 230 or the insulation member solution is placed in the same space as the internal space and cured for 30 minutes to generate the insulation member 230 in advance. The generated heat insulating member 230 can be disposed in the internal space.

In a state in which the heat insulation member 230 is disposed in the inner space, the first glass plate 210 having a thickness of 6 mm is applied by applying a constant pressure P to the spacer portion 240 to face the second glass plate 220.
