Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to an air cap insulating sheet used as a heat insulating material.

The air-cap insulating sheet, which is normally used for the purpose of thermal insulation, is used to reduce the heat loss rate caused by the temperature difference between indoor and outdoor by attaching to the window in winter.

In order to attach the air-cap insulating sheet, a film material provided in a roll form is unfolded, an altar is cut to a desired size, and water is sprayed on the window so that the film adheres to the glass with the surface tension of water between the film and the window.

However, when the sprayed water is normally dried, the surface tension weakens, and the film starts to peel off from the glass window from the end of the film. Especially in winter, when the rolls are circulated, the restoring force of the stretched film to return to the roll shape accelerates the peeling phenomenon. In order to prevent peeling, some installers use additional attachment means such as applying double-sided tape. Such an air-cap insulating sheet with a double-sided tape is difficult to recycle as well as another problem of making glass windows dirty through taping marks ≪ / RTI >

On the other hand, the adhered air-cap insulating sheet appears to be attached to the glass window without falling off even when the area is peeled off by about 40%. The heat loss rate becomes larger by the peeled area, .

1 and 2, an air cap insulating sheet 1 according to an embodiment of the present invention includes a first film 10 for supporting an air cap 21, a plurality of air caps 21, And a second film (20) provided so as to protrude.

The first and second films 10 and 20 may be formed of a flexible laminated sheet and may be made of a general plastic classified as a petrochemical or a biodegradable plastic material made of a crop such as corn can do.

The second film 20 forms an uneven surface through a plurality of air caps 21, and the first film 10 becomes a flat surface. As shown in FIG. 2, the air cap 21 is provided with a first adsorption groove 22 for imparting a self-adsorption function to the air-cap insulating sheet 1, ) May be provided.

The first suction groove 22 is provided so as to be recessed inward at the center of the front end portion of the air cap 21 in the projecting direction of the air cap 21. When the front end of the air cap is brought into contact with the adhered surface such as the window 30, And may be provided to form an interrupted space between the surfaces.

The first adsorption grooves 22 can be simply formed through a structure in which the second film 20 on the center of the distal end of the air cap 21 is adhered to the first film 10, 22 may be provided so as to remain attached to the first film 10.

When adhering the air-cap insulating sheet 1 to the windshield 30, water 100 is sprayed onto the windshield 30 and the air-cap insulating sheet 1 is cut from the fabric so as to match the size of the windshield 30 All you have to do is complete the bet.

The air cap insulating sheet 1 is placed on the surface of the glass window 30 in which water is sufficiently sprayed and in this state the air cap insulation is formed so that the tip end of the air cap 21 having the first suction groove 22 is pressed to the adherend As shown in FIG. 3, when the sheet 1 is manually pressed to the glass window side, a certain amount of air in the first suction groove 22 escapes to the outside due to the pressure at this time, A pressure difference is formed between the inside and the outside of the air cap insulating sheet 1, and the air cap insulating sheet 1 is kept attached to the surface to be adhered by the pressure difference.
