Abstract
【解決手段】無機繊維の芯材と、該芯材を内包するガスバリア性の外包材を有し、該外包材にゲッター剤を入れて内部を減圧して封止した断熱パネルであって、前記断熱パネルは、無機繊維内部に波板状の骨材を配置してあることを特徴とする。骨材は塑性変形性を有する材質とすることが好ましく、アルミ,鉄,銅,SUSのうちいずれか一種又は複合したものを用いることができ、有機樹脂を主体とするものも用いることができる。
【選択図】図1
Description
〔実施例〕
以下、本発明の断熱パネル及び該断熱パネルを挿入した冷蔵庫の構造と作製について、図面を参照して説明する。
(mm),辺の間の角度をθ(°),板の厚さをd(mm)とする波板状骨材である。波状部分は自由度があり、断熱材を変形することが可能である。中断の平面形状にしてから下段のように湾曲させたり、はじめから湾曲させた骨材を用いて下段の形状とすることもできる。
(N)を測定し評価した。その結果、形状折り曲げ性は70.9Nであった。
106.9N で、形状保持性は良好であった。実施例1と同様の耐久試験後の熱伝導率は3.2mW/m・Kを示し、経時劣化は抑制されていた。
108Nで、形状保持性は良好であった。実施例1と同様の耐久試験後の熱伝導率は9.2mW/m・Kを示した。
25%低減できる冷蔵庫を提供できた。
8462,信越化学製のX−20−1614,X−20−1634,日本ユニカ製のSZ−1127,SZ−1671を用いる。上記材料を用いて、硬質ポリウレタンフォームを発泡する。発泡機は、例えばプロマート社製PU−30型発泡機が用いられる。発泡条件は、発泡機の種類によって多少異なるが通常は液温18〜30℃,吐出圧力80〜150
kg/cm2,吐出量15〜30kg/min,型箱の温度は35〜45℃が好ましい条件である。
