Abstract

<P>PROBLEM TO BE SOLVED: To provide a printinf film capable of improving heat barrier properties and design properties at the same time by solving a problem wherein the design properties of a building material such as an aluminum building material, a vinyl building material or the like is enhanced by bonding the printing film to the building material but the printing film receves solar rays directly to be heated by solar heat and strain or a sound coccurs by the temperature rise of the building material. <P>SOLUTION: Printing ink is applied to a film having high solar radiation reflectivity to form an ink layer on the film. This film permits the transmission of infrared rays by the ink layer while holding design properties and reflects infrared rays by the film having high solar radiation reflectivity not only to suppress the temperature rise of the surface of the building material but also to prevent the occurrence of strain and the emission of a sound. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【発明が属する技術分野】
本発明は、住宅建材等の被覆に用いられ、日光照射に起因する温度上昇を防ぎ、色彩、意匠、美観をも向上させることが出来る赤外線反射機能を有する印刷フィルムに関するものである。
【0002】
【従来の技術】
塗料に置き換わり、作業性の向上のため、予め用途に応じカラーフィルムを作り、塗料による塗装と同様の効果を簡便にしてきた。又、塗料には出来ない意匠の多様化でフィルムが使用されてきたが、色彩、意匠、美観の向上が求められている。
【0003】
遮熱性を有するフィルムは古くから研究されており、フィルム表面に金属層を蒸着する技術、熱線吸収技術、特開2002−12679、特開2002−12683のような反射技術が公開されているが、このような方法では、色彩、意匠、美観を兼ね備えた遮熱効果のある印刷フィルムは出来なかった。
【0004】
アルミ建材、ビニル建材等に印刷フィルムを貼り付け、意匠性を向上させているが、太陽光を直接受け、太陽熱で加温され、アルミ建材、ビニル建材等の温度上昇により歪が発生したり、音鳴りが発生し、遮熱性と意匠性を同時に解決できるものではなかった。
【0005】
【発明が解決しようとする課題】
本発明は、色彩、意匠、美観と遮熱効果を兼ね備えた印刷フィルムを提供することを目的とするものである。
【0006】
【課題を解決するための手段】

【0009】
さらに、印刷インキの膜厚は0.5μm〜20μm以下に塗布し、太陽光を透過させ、日射反射率の高いフィルムで反射させることで建材表面温度上昇が抑えられ、歪、音鳴りを防止することが出来る。
【0010】
請求項2記載の本発明によれば、従来のフィルムと比較して、表面温度が高<ならないので、サッシ、ドアー等の表面温度上昇が抑えられ、歪が生じず、開閉がスムーズに出来る。
【0011】

Good, but inks generally used for building materials may be used.
[0009]
Further, the thickness of the printing ink is applied to a thickness of 0.5 μm to 20 μm or less, the sunlight is transmitted, and the film is reflected by a film having a high solar reflectance to suppress a rise in the surface temperature of the building material, thereby preventing distortion and noise. I can do it.
[0010]
According to the present invention, since the surface temperature does not become higher than that of the conventional film, the rise in the surface temperature of the sash, the door and the like is suppressed, and no distortion occurs, and the opening and closing can be performed smoothly.
