Description
「エポキシ樹脂」は、複数のエポキシ基を含む、広い範囲の化学物質を意味する。エポキシ樹脂は、当分野で周知であり、Second Edition of the Encyclopedia of Polymer Science and Engineering, Volume 6, pp. 322−382 (1986)の「エポキシ樹脂(Epoxy Resins)」と題した章に記載されている。
「強化剤」としても知られる「耐衝撃改良剤」は、配合の耐衝撃性を改良するために配合に添加される任意の材料を意味する。多くの市販の耐衝撃改良剤が、当分野で周知であり、固体熱膨張材料における使用に適している。
当業者により「発泡剤」と呼ばれることもある「加熱活性化発泡剤」は、所定量の熱の適用によって、その母材(host)を所定の量だけ膨張させる物理作用剤または化学作用剤である。
熱膨張材料の実施形態は、少なくとも1種の「フィラー」を含むことができる。適切なフィラーには、繊維フィラー、球状フィラー、板状フィラー、およびナノ粒子フィラーが含まれてよい。繊維フィラーは、ガラス繊維またはウォラストナイト繊維などの無機であってよく、あるいは別の方法では、天然または有機であってよい。天然または有機繊維には、非限定的に、炭素繊維、アラミドKEVLAR繊維、セルロース系繊維、ジュート、麻、および同様のものが含まれる。球状フィラーは、有機または無機であってよい。非限定的に、有機球状フィラーは、ポリマー球であってよく、無機球状フィラーは、ガラスマイクロバルーン、セラミック微小球、ヒュームドシリカ(有機的に変性したまたは未変性の)、熱分解法シリカ(有機的に変性したまたは未変性の)、および同様のものであってよい。板状フィラーは、黒鉛、タルク、雲母、および当業者に周知の他の物質などの無機であってよい。ナノ粒子フィラーは、非限定的に、イライトまたは(Southern Clayより市販のCLOISITE 30BまたはCLOISITE 93Aなどの)有機的に変性したモンモリロナイトナノクレイのようなフィロケイ酸塩、ナノシリカ(好ましくは反応性基を有する)、およびカーボンナノチューブ、ハイブリッド有機−無機コポリマー(hybrid organic−inorganic copolymer)、多面体オリゴマーシルセスキオキサン(POSS)を含むことができる。
固体熱膨張材料は、その全体を参照により本明細書に組み込んだ、米国特許第6,649,243号に記載されたように、標準の製造設備を用いてペレットに混ぜ合わせまたは形成し、次いで、支持体に射出成形することができる。射出成形の代わりの方法は、当分野で周知であり、固体熱膨張材料での使用に検討される。射出成形(または未硬化材料の加工に選択される任意の他の方法)は、膨張材料の硬化活性化温度を下回る温度でおこなう。膨張材料を、押し出し、パフォーム(perform)、非限定的に、ジョイント、フレーム、またはピラーを含む支持体との加熱成形、および支持体なしの加熱成形を含めた、当業者に周知の任意の方法を用いて、加工、形づくりまたは成形することができる。
次の実施例を、ブレンダーで成分を混合し、次いでペレタイザーを有する二軸スクリュー押出機でこれをコンパウンドすることによって調製した。機械的試験用の試験片を、射出成形によって調製した。特に指定のない限り、ガラス転移温度は、DSCによって測定された。成分のすべての百分率は、重量%である。
