本発明は、全反射現象によって日光を反射せしめて外部

気層による断熱効果によって内部の温度の保持を容易に
することのできる断熱遅閉フィルム積層材に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention reflects sunlight by total internal reflection so that the inside cannot be seen from the outside, and also reduces the temperature inside by using the heat insulating effect of the air layer. This invention relates to a heat insulating slow-closing film laminate that can be easily held.

もあるが、この場合も室内が相当暗くなることは言うま
でもない。Generally, curtains, shutters, etc. are used to prevent the inside from being seen from outside. However, with such materials, although it is not possible to see into the interior from the outside, there is a problem that the interior becomes dark because sunlight closes late. In addition, metals such as aluminum are sometimes used on the surface of glass or plastic films, but in this case as well, the interior becomes dark, and the outside is exposed to strong reflected light from the metal surface. The problem remains. Furthermore, there are cases where a plastic film colored brown is attached to the window glass with an adhesive, but it goes without saying that this also makes the room quite dark.

効果の面で十分ではない。Another method is to attach a transparent thermoplastic polymer film with built-in air bubbles to the window glass using adhesive tape, etc., in order to create a heat insulating effect, but this method does not seal off the interior of the room from the outside. Since this is not possible, the only suitable method is to color the plastic film to absorb sunlight. Additionally, a method of etching the glass surface as with frosted glass has been used for a long time, but this method is also not sufficient in terms of heat insulation.
このように従来各種の方法が試みられているが、遅閉効

ない。As described above, various methods have been tried in the past, but no one has been found that satisfies both the delayed closing effect and the heat insulation effect at the same time.

色することができる。(Means for solving the problem) However, according to the present invention, the above problem can be solved when the thickness is 50 to 5
One plane of the 00 μm colorless and transparent first thermoplastic polymer film is formed into a sawtooth shape or a similar shape so that incident light from the opposite plane is totally reflected, and then a thick film is formed on this plane. The present invention is solved by providing an insulating slow-closing film laminate to which is adhered a colorless and transparent second thermoplastic polymer film with a thickness of 50 to 500 μm. This film laminate material can be produced by, for example, applying an adhesive to the plane of the second thermoplastic polymer film opposite to the first thermoplastic polymer film and attaching this surface to a window glass. Sunlight causes total internal reflection,
The interior is completely sealed off, preventing the outside from seeing the interior, and at the same time, the air layer built in between the two layers of film provides a heat insulating effect. Furthermore, unlike conventional methods in which the film of the present invention is vacuum-deposited with metal or colored to reduce the amount of light, it does not darken the room. Of course,
The plastic film can be colored by kneading with a color pellet, printing, etc. to a color tone that is preferable for lighting the room.

and the second thermoplastic polymer film each have a thickness of 20 to 500 μm, preferably 30 to 500 μm. If this thickness is too thick, it will take a long time to cool the sawtooth shaped film during processing, which will reduce production efficiency, which is undesirable.On the other hand, if it is too thin, it will be difficult to mold the sawtooth shape, which is undesirable. .

~450 μm) to prevent incident light 5 from the outside from being totally reflected and reaching the inside. To produce such a total internal reflection phenomenon, the opposite plane of the sawtooth-shaped film is used to face the incident light. On the other hand, according to the present invention, the second thermoplastic polymer film 4 is adhered by an appropriate method to the plane of the first thermoplastic polymer film opposite to the incident light side, and the first thermoplastic polymer film 3 ( A space is created in which air 6 exists between the serrations (the serrations of the thermoplastic polymer film) and the second thermoplastic polymer film. Due to the air 5 present in this space, the film laminate of the present invention exhibits an excellent heat insulating effect. Note that there are no particular limitations on the compositions of the first and second thermoplastic polymer films used in the film laminate according to the present invention.
