Abstract
【解決手段】 相変化物質と膨張黒鉛とを含み、容積比で1〜40%の空隙を含むことを特徴とする蓄熱材及び格子状、パイプ状等の形態の筐体を用いた蓄熱材の製造方法に関し、前記、膨張黒鉛としてかさ密度が0.002〜0.02g/cm3の未粉砕の膨張黒鉛と、膨張黒鉛シートを粉砕したかさ密度が0.02〜0.20g/cm3の膨張黒鉛粉砕粉の混合物を用いることが好ましい。
【選択図】 なし
Description
上記膨張黒鉛粉砕粉の混合比は、全膨張黒鉛に対する重量比で0〜90%であることが好ましい。90%よりも大きい場合には、膨張黒鉛と相変化物質の分離が発生する。さらに好ましい範囲は10〜80%である。
プレス機等を用いて膨張黒鉛、相変化物質混合物を圧縮すると蓄熱材の成形体を得ることが出来る。
実施例1〜7、比較例1〜4
日立化成製−膨張黒鉛(HGP)に溶融したパラフィンの一種である融点20〜23℃のヘプタデカン(和光純薬製;C17H36)を徐々に加えていき、軽く圧力をかけた際に膨張黒鉛からヘプタデカンが染み出てくるかどうかを目視で確認し、膨張黒鉛に吸収されるヘプタデカンの限界吸収量の測定を行った。また、スクリュー押出機を用いて圧縮した上記膨張黒鉛、及び上記膨張黒鉛をシート化した膨張黒鉛シート(HGP−5)粉砕粉についても同様の測定を行った。各試験条件のn数は3で、平均値を結果とした。測定結果を表1及び表2に示す。
