Description
その接着層は、厚さが0..5mm以下のものである。
本発明の電波吸収体は、表面が大型のセラミック板であるため、小型タイルのような電波吸収性能と高光拡散反射性能を不利にする目地部割合が極力抑えられ、優れた吸収性能を発揮出来るとともに、トンネル内壁で利用される場合、表面が汚れた後の洗浄により高光拡散反射性能を回復でき、耐久性のあるものとなり、より実用性の高いものとなる。 また大型化によって施工の効率化も図れる。
本発明の電波吸収体は、不燃性、汚染回復性、対候性、耐久性に優れ、大型であるため、電波吸収が必要で、不燃性が求められる建物や構造物においてもその利点から大いに利用が見込まれる。
Claims (1)
- 表面層に釉薬を施した比誘電率が5.0以下で、大きさとして、幅200mm以上、長さ600mm以上の大型で、JIS−A−5209に規定する陶磁器質タイルに相当する大型磁器質セラミック板、中間層に無機質パウダーを主体に導電性材料パウダー、軟磁性パウダー、還元鉄パウダー及び熱硬化性樹脂の構成物からなるものを分散混合後に熱プレス硬化した板、裏面層に金属板又は金属体を有する面材で構成された3層の物で板状をなすことを特徴とする電波吸収体。
