Abstract
Description
本開示は、一般に、断熱材料及びその物品に関し、より具体的には、エアロゲル粒子などの断熱性粒子、ポリマーマトリックス及び膨張性微小球を含む断熱材料に関する。
断熱用のエアロゲルの使用及びエアロゲルの低熱伝導率はよく知られている。良好な熱伝導特性は約95%を超えるエアロゲルの非常に高い多孔性、及び、大気圧での空気分子の平均自由行程のサイズより小さい又は約100nmより小さいエアロゲル材料の細孔サイズにより生じる。細孔サイズが小さいために、材料内の空気分子の移動性は制限され、熱伝導における空気の有効性は低下し、熱伝導率が低くなる。大気条件下において、空気は熱伝導率が約25mW/mK(ミリワット/メートルケルビン)である。フォーム、バッティング、羊毛及びその他の一般的な断熱材料などの、より大きな細孔サイズの断熱材は熱伝導率が約40mW/mKであり、放射及び固体伝導の寄与により空気の熱伝導率よりも高い。エアロゲルの粉末及びビーズは、熱伝導率が約9〜20mW/mKであることが知られている。しかしながら、このような非常に高度に多孔質で低密度の材料は、設置、取り扱い、加工、成形が特に難しくなる大量の粉塵により、粉末の形での多くの用途に有用でなく、さらに安全性の問題が生じる。
本開示は、1つの実施形態において、ポリマーマトリックス、エアロゲル粒子及び膨張微小球を含む断熱材料であって、前記エアロゲル粒子は30質量%以上の量で存在し、前記ポリマーマトリックスは20質量%以上の量で存在し、前記膨張微小球は0.5〜15質量%の量で存在し、ここで、質量パーセントは、ポリマーマトリックス、エアロゲル粒子及び膨張微小球の総質量に基づいており、また、前記断熱材料の熱伝導率は大気条件で40mW/mK未満である、断熱材料を対象とする。
添付図面は、本開示のさらなる理解を提供するために含まれ、本明細書に組み込まれ、本明細書の一部を構成し、実施形態を示し、記載とともに本開示の原理を説明する役割を果たす。
当業者は、本開示の様々な態様が、意図された機能を発揮するように構成された任意の数の方法及び装置によって実現されうることを容易に理解するであろう。また、本明細書で参照する添付の図面は必ずしも縮尺通りに描かれているわけではなく、本開示の様々な態様を示すために誇張されている可能性があり、その点で図面は限定するものと解釈されるべきではないことに留意されたい。
特定の方法及び装置を以下に記載するが、当業者が適切と決定する任意の方法又は装置を代替的に利用できることを理解されたい。
水蒸気透過速度テスト-(MVTR)
MVTR=(δP値*24)/((1WVP)+(1+WVPapp値))
引張強度=最大荷重/断面積
サンプルの厚さは、熱伝導率計の一体型厚さ測定で測定した(Laser Comp Model Fox 314 Laser Comp Saugus, MA)。単一の測定結果を記録した。
本開示のサンプルの熱伝導率は、ASTM C518の一般的な教示に加えて、大気条件(約298K及び101.3kPa)での圧縮の追加に従って、カスタムメイドの熱流量計熱伝導率テスターを使用して測定した。テスターは、熱流センサ(Model FR-025-TH44033, Concept Engineering, Old Saybrook, CT)及びその表面に埋め込まれた温度センサ(サーミスター)を備えた加熱アルミニウム板、及び、室温に維持された第二のアルミ板であって、その表面に温度センサが埋め込まれた第二のアルミニウム板からなった。
熱伝導率は、サンプルを圧縮しないで測定した。サンプルは、Laser Comp Model Fox 314熱伝導率アナライザ(Laser Comp Saugus, MA)で測定した。単一の測定結果を記録した。
空気流測定はATEQモデルD520(ATEQ Livonia, MI)で行われ、計器には2.99cm2のフロー面積を有する丸いシールが備えられていた。2つの測定値の平均を記録した。
空気流に対するサンプルの抵抗性は、ガーレー密度計(Model 4340, Gurley Precision Instruments Troy, NYにより製造)によって測定した。結果は、100立方センチメートルの空気が4.88インチの水圧で1平方インチの試験サンプルを通過する秒数での時間であるガーレー数で報告される。1回の測定結果を記録した。
水浸入圧は、膜及び/又は布帛を通る水の浸入の試験方法を提供する。試験サンプルは、損傷を与えないように注意しながら、一対の試験プレートの間に固定する。下部プレートには、サンプルのセクションを水で加圧する能力がある。水が浸入した証拠の指標として、サンプルの上で非加圧面のプレート間の紙タオル片を配置する。次に、ペーパータオルを通る水の最初の目に見える兆候が突破圧又は浸入圧を示すまで、サンプルを少しずつ加圧する。圧力を水浸入圧として記録した。単一の測定結果を記録した。
約75ミリメートル(mm)x200mmのサイズの断熱材料のサンプルを、試験前に2時間、21°C及び50%±2%の相対湿度で条件調整した。条件調整したサンプルを試験のために取り出すまで、条件調整した後に密閉サンプルバッグに入れた。
