Abstract
Description
近年、一年中、高温多湿の蒸暑地域でも、省エネルギー化の進展が想定されるため、真空断熱材の需要が見込まれる。また、温暖化の進行によって、地域によっては湿度が上昇する可能性がある。
本開示に係る断熱構造体は、真空断熱材および発泡断熱材を備えるパネル状である。真空断熱材は、ガスバリア性を有する外被材と、外被材の内部に封入される芯材と、芯材とともに外被材の内部に封入される気体吸着材と、を有している。外被材の内部は減圧状態である。外被材のうち、真空断熱材の一方の面である第一面を構成する外被材は、フィラーとして少なくとも層状粘土鉱物を含有するガスバリア層を含む。外被材のうち、真空断熱材の他方の面である第二面を構成する外被材は、少なくとも金属で構成されたガスバリア層を含む。気体吸着材は、少なくとも水分吸着性を有する。発泡断熱材は、少なくとも真空断熱材の第一面を被覆する構成である。
まず、本開示に係る断熱構造体について、その代表的な一例である断熱パネルを挙げて、図1を参照して具体的に説明する。
次に、真空断熱材20が備える外被材22の具体的な構成例について説明する。
本開示においては、発泡断熱材13は、真空断熱材20の外面の少なくとも一部を被覆する。層状粘土鉱物は親水性であるため、多湿環境が長期にわたって継続すると、層状粘土鉱物が水分を含有する。層状粘土鉱物が水分を含有すると、粘土鉱物ガスバリア層222のガスバリア性、すなわち真空断熱材20の外被材22のうち、表面側の外被材22Aのガスバリア性が低下してしまう。
