しかしながら、このような従来の技術にあっては、切断された金属シートに接着剤を塗布する作業が面倒で且つ接着剤の硬化に相当な時間を要することから、生産性の面で不利であった。   However, such a conventional technique is disadvantageous in terms of productivity because the operation of applying the adhesive to the cut metal sheet is troublesome and requires a considerable time for the adhesive to cure. It was.

本発明は、このような従来の技術に着目してなされたものであり、生産性が向上する断熱積層パネルの製造方法を提供するものである。   The present invention has been made by paying attention to such a conventional technique, and provides a method for manufacturing a heat-insulating laminated panel with improved productivity.

請求項１記載の発明は、金属シートに熱可塑性樹脂からなる接着フィルムを熱融着して接合し、該接着フィルムを接合した金属シートを所定形状に切断し、接着フィルムを向かい合わせた切断後の２枚の金属シートの間に、断熱材を挟み込んで熱プレスし、２枚の金属シートと断熱材とを接着フィルムを介して積層したことを特徴とする。   According to the first aspect of the present invention, an adhesive film made of a thermoplastic resin is bonded to a metal sheet by heat fusion, the metal sheet to which the adhesive film is bonded is cut into a predetermined shape, and the adhesive film is cut face to face. Between the two metal sheets, a heat insulating material is sandwiched and hot pressed, and the two metal sheets and the heat insulating material are laminated via an adhesive film.

請求項２記載の発明は、接着フィルムが、オレフィン系、変性オレフィン系、ポリウレタン系、エチレン−酢酸ビニル共重合樹脂系の何れか１つをベースとした、マレイン酸変成接着樹脂フィルムであることを特徴とする。   The invention according to claim 2 is that the adhesive film is a maleic acid-modified adhesive resin film based on any one of olefin, modified olefin, polyurethane, and ethylene-vinyl acetate copolymer resin. Features.

請求項３記載の発明は、断熱材が、発泡樹脂、ペーパーハニカム、アルミハニカム、フェノール含浸ロックウールの何れか１つであることを特徴とする。   The invention according to claim 3 is characterized in that the heat insulating material is any one of foamed resin, paper honeycomb, aluminum honeycomb, and phenol-impregnated rock wool.

請求項４記載の発明は、発泡樹脂が、ポリプロピレン、ポリエチレン、ポリスチレン、ポリウレタン、フェノールの何れか１つであることを特徴とする。   The invention according to claim 4 is characterized in that the foamed resin is any one of polypropylene, polyethylene, polystyrene, polyurethane, and phenol.

請求項１記載の発明によれば、金属シートと断熱材を接合するために、接着剤でなく、接着フィルムを用い、その接着フィルムを加熱により金属シートに接合するようにしたため、作業が容易で、時間も要しない。しかも、切断前の金属シートに接着フィルムを接合し、接合後に接着フィルムごと金属シートを所定形状に切断するため、更に作業が容易である。   According to the first aspect of the invention, in order to join the metal sheet and the heat insulating material, an adhesive film is used instead of an adhesive, and the adhesive film is joined to the metal sheet by heating. It does n’t take much time. Moreover, since the adhesive film is joined to the metal sheet before cutting and the metal sheet is cut into a predetermined shape together with the adhesive film after joining, the operation is further facilitated.

請求項２記載の発明によれば、接着フィルムとして、オレフィン系、変性オレフィン系、ポリウレタン系、エチレン−酢酸ビニル共重合樹脂系の何れか１つをベースとした、マレイン酸変成接着樹脂フィルムを用いたため、金属シートへの加熱接合時と、断熱材への熱プレス時の２回加熱されることにより、強固な接着を形成し、金属シートと断熱材との接着強度が高まる。   According to the invention described in claim 2, as the adhesive film, a maleic acid-modified adhesive resin film based on any one of olefin, modified olefin, polyurethane, and ethylene-vinyl acetate copolymer resin is used. Therefore, by being heated twice at the time of heat bonding to the metal sheet and at the time of hot pressing to the heat insulating material, a strong bond is formed, and the adhesive strength between the metal sheet and the heat insulating material is increased.

請求項４記載の発明によれば、発泡樹脂として、ポリプロピレン、ポリエチレン、ポリスチレン、ポリウレタン、フェノールの何れか１つを用いることができるため、汎用性が高い。   According to the invention described in claim 4, since any one of polypropylene, polyethylene, polystyrene, polyurethane, and phenol can be used as the foamed resin, the versatility is high.

以下、本発明の最良の実施形態を図１〜図３に基づいて説明する。図１は、製品としての断熱積層パネル１を示す断面図である。この断熱積層パネル１は、発泡ウレタン製の断熱材２を、マレイン酸変成接着樹脂製の接着フィルム３を介して、２枚の金属シート４に挟み込んだ構造をしている。金属シート４は薄い鋼板であるが、アルミでも、ステンレスでも、それらの塗装板でも良い。   Hereinafter, the best embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a cross-sectional view showing a heat insulating laminated panel 1 as a product. This heat insulation laminated panel 1 has a structure in which a heat insulating material 2 made of urethane foam is sandwiched between two metal sheets 4 via an adhesive film 3 made of maleic acid modified adhesive resin. The metal sheet 4 is a thin steel plate, but may be aluminum, stainless steel, or a painted plate thereof.

次に、図２に基づいて、金属シート４に接着フィルム３を接合する工程を説明する。金属シート４と接着フィルム３を、それぞれのロール５、６から引き出し、それらを押付ローラ７により重ね合わせながら、ヒーター８を近接させた加熱ローラ９に接触させる。この時、接着フィルム３が加熱溶融（一次加熱）して金属シート４に貼り付く。マレイン酸変成接着樹脂製の接着フィルム３は、加熱されることにより、金属シート４と強固に接着する。酸変性の水素原子が金属表面の水酸基と強固な水素結合を形成するためである。   Next, the process of joining the adhesive film 3 to the metal sheet 4 will be described based on FIG. The metal sheet 4 and the adhesive film 3 are pulled out from the respective rolls 5 and 6, and are brought into contact with the heating roller 9 that is brought close to the heater 8 while being superposed by the pressing roller 7. At this time, the adhesive film 3 is heated and melted (primary heating) and adhered to the metal sheet 4. The adhesive film 3 made of maleic acid-modified adhesive resin is firmly bonded to the metal sheet 4 by being heated. This is because the acid-modified hydrogen atom forms a strong hydrogen bond with the hydroxyl group on the metal surface.

そして、この接着フィルム３が貼り付けられた金属シート４を、２組の送りローラ１０、１１にて冷却ローラ１２間に搬送される。冷却ローラ１２で金属シート４と接着フィルム３は冷却され、互いに強固な接合となる。冷却ローラ１２をを通過した接着フィルム３付きの金属シート４は、巻取ロール１３に巻き取られて、保管場所に搬送される。   Then, the metal sheet 4 to which the adhesive film 3 is attached is conveyed between the cooling rollers 12 by two sets of feed rollers 10 and 11. The metal sheet 4 and the adhesive film 3 are cooled by the cooling roller 12 and are firmly bonded to each other. The metal sheet 4 with the adhesive film 3 that has passed through the cooling roller 12 is taken up by a take-up roll 13 and conveyed to a storage location.

その後、接着フィルム３付きの金属シート４は、巻取ロール１３から引き出されて所定形状の金属シート４に切断される。切断された金属シート４の片面には接着フィルム３が接合されている。   Thereafter, the metal sheet 4 with the adhesive film 3 is pulled out from the take-up roll 13 and cut into the metal sheet 4 having a predetermined shape. An adhesive film 3 is bonded to one side of the cut metal sheet 4.

接合された２枚の金属シート４を互いに接着フィルム３を対向させた状態にして、その間に断熱材２を挟み、上下一対の加熱加圧体１４の間にセットする。そして、その加熱加圧体１４を接近させて、金属シート４で断熱材２を挟んだ状態のまま加熱と加圧を加える。   Two bonded metal sheets 4 are placed with the adhesive film 3 facing each other, and the heat insulating material 2 is sandwiched therebetween, and is set between a pair of upper and lower heating and pressing bodies 14. And the heating pressurization body 14 is made to approach and heat and pressurization are applied with the heat insulating material 2 sandwiched between the metal sheets 4.

これにより、接着フィルム３を介して、金属シート４と断熱材２とが強固に接合される。特に、マレイン酸変成接着樹脂製の接着フィルム３は、再び加熱溶融されることにより、金属シート４に対して、一次加熱後の強度よりも更に強固な接着を形成するために、ますます剥がれない状態となる。二度の加熱により、一度の加熱では得られない強度となるため、本プロセスによる製造方法は、断熱積層パネルの製造方法として好適である。   Thereby, the metal sheet 4 and the heat insulating material 2 are firmly bonded via the adhesive film 3. In particular, the adhesive film 3 made of maleic acid modified adhesive resin is not peeled off more and more in order to form a stronger bond to the metal sheet 4 than the strength after the primary heating by being melted again by heating. It becomes a state. Since the strength that cannot be obtained by one heating is obtained by heating twice, the manufacturing method according to the present process is suitable as a method for manufacturing a heat insulating laminated panel.

本発明に係る断熱積層パネルは、保冷車の保冷室の壁などや、断熱建材に利用することができる。   The heat insulation laminated panel which concerns on this invention can be utilized for the wall of the cold storage room of a cold storage vehicle, etc., or heat insulation building materials.
