ートの製造法を提供するにある。DETAILED DESCRIPTION OF THE INVENTION The present invention consists of two transparent thermoplastic resin sheets 1 facing each other,
A shiny metal film 3 is coated on at least one inner surface of 2.
The transparent thermoplastic resin sheets 1 and 2 are vapor-deposited to a thickness of 1 to 0.07 μm, and a large number of bag-shaped recesses 4, 4, etc. projecting outward are provided on one of the transparent thermoplastic resin sheets 1, 2, and the metal film 3 is passed through the two sheets. The method of manufacturing a heat insulating sheet is characterized by thermo-compression bonding of transparent thermoplastic resin sheets 1 and 2 of To provide a method for manufacturing a heat insulating sheet that can be easily manufactured by pressure bonding.
従来、空気泡を有するシートにアルミニウムの如き光沢
ある金属膜を設けるに当ってはシートの外側面に金属箔
を貼着していたために、金属膜が大気中の酸素、水分等
に直接接触して酸化され、金属光沢が短期間のうちに消
失して反射効率が底下し断熱性を劣化させる欠点があっ
た。Conventionally, when providing a shiny metal film such as aluminum on a sheet with air bubbles, metal foil was attached to the outer surface of the sheet, which caused the metal film to come into direct contact with oxygen, moisture, etc. in the atmosphere. This has the drawback that the metallic luster disappears in a short period of time, and the reflection efficiency bottoms out, deteriorating the heat insulation properties.
本発明はかかる従来の欠点を解消せんとするもので、以
下添付図に基づいて詳細に説明する。The present invention aims to eliminate such conventional drawbacks, and will be described in detail below with reference to the accompanying drawings.
二枚の透明熱可塑性樹脂シート１，２としてはポリエチ

等の任意のものが用いられ、この二枚の透明熱可塑性樹
脂シート１，２の一方又は両方の片面に例えばアルミニ

。As the two transparent thermoplastic resin sheets 1 and 2, any material such as polyethylene, polypropylene, polyvinyl chloride, polyester, etc. can be used. A metal film 3 having good metallic luster, such as aluminum, is applied by vapor deposition.
この蒸着による金属膜３の厚みは０．０１〜０．０７μ
の範囲とする。The thickness of the metal film 3 obtained by this vapor deposition is 0.01 to 0.07μ.
The range shall be .
これは厚みが０．０１μ未満であると反射率が著しく底
下し、逆に厚みが０．０７μを越えると透明熱可塑性樹
脂シート１，２の熱融着が不充分となるためである。This is because if the thickness is less than 0.01 μm, the reflectance will drop significantly, and if the thickness exceeds 0.07 μm, the thermal fusion of the transparent thermoplastic resin sheets 1 and 2 will be insufficient.

に空気を封入する。In Figure 1, metal films 3 and 3 are deposited on one side of both transparent thermoplastic resin sheets 1 and 2, and the two transparent thermoplastic resin sheets 1 and 2 are placed so that the metal films 3 and 3 are on the inside. A large number of small cylindrical bag-shaped recesses 4, 4, which are opposed to each other, have openings on the metal film 3 side, and protrude outward in one transparent thermoplastic resin sheet 1.
. . is applied by vacuum forming, and then both sheets 1 and 2 are stacked and bonded under heat, and the recesses 4, 4 . . . are sealed and air is sealed inside.
この空気は乾燥空気とすることが望ましい。This air is preferably dry air.
尚、第２図は一方の透明熱可塑性樹脂シート２のみに金
属膜３の蒸着を施した他は第１図の場合と同様にした例
を示す。Incidentally, FIG. 2 shows an example similar to that shown in FIG. 1, except that the metal film 3 was vapor-deposited only on one transparent thermoplastic resin sheet 2.
本発明によって得られた断熱シートは相対向せる二枚の
透明熱可塑性樹脂シートの少なくとも一方の内面に光沢
ある金属膜を施してあるので、金属膜は直接外気、水分
等に接触して酸化されることがなく、良好な金属光沢を
長期に亘って維持し得て、凹所内の空気による断熱効果
に加えて赤外線反射による断熱効果を長期間発揮するこ
とができる。The heat insulating sheet obtained by the present invention has two opposed transparent thermoplastic resin sheets with a shiny metal film applied to the inner surface of at least one of them, so that the metal film does not oxidize when it comes into direct contact with outside air, moisture, etc. Good metallic luster can be maintained over a long period of time, and in addition to the heat insulating effect due to the air within the recess, the heat insulating effect due to infrared reflection can be exhibited for a long period of time.
本発明にあっては上述のように金属膜が蒸着にて施され

金属微粒子の集合体として形成され、このために金属微
粒子の間隙を介して二枚の透明熱可塑性シートを直接熱
圧着にて強固に接着せしめ得る利点がある。In the present invention, since the metal film is applied by vapor deposition as described above, the metal film is not damaged even if a bag-shaped recess is formed, and the recess can be processed after vapor deposition. Since the film is deposited to a thickness of 0.01 to 0.07μ, the metal film is formed as an aggregate of metal particles, and for this purpose, two transparent thermoplastic sheets are directly heated through the gap between the metal particles. It has the advantage of being able to be firmly bonded by pressure bonding.
