Abstract
Description
以下では、本発明に係るコンパウンドの製造方法の一例が説明される。ただし、本発明に係るコンパウンドの製造方法は、下記の製造方法に限定されない。
[コンパウンド粉の作製]
<金属フィラーの調製>
第一金属粉末及び第二金属粉末を袋に入れて、袋を閉じた。袋を両手で3分間振って第一金属粉末及び第二金属粉末を混合することにより、金属フィラーを得た。袋はPE(ポリエチレン)から作製されていた。袋の寸法は、470mm×670mmであった。
メタクリルシラン(シランカップリング剤)が、袋内の金属フィラーへ添加された。メタクリルシランの質量は、5.43gであった。メタクリルシランは、信越化学工業株式会社製のKBM‐503であった。袋を両手で3分間振って金属フィラー及びメタクリルシランを混合することにより、第一混合物を得た。第一混合工程により、金属フィラーを構成する各金属粒子の表面が、メタクリルシランで覆われた。
第二混合工程では、上記の袋とは別の袋が用いられた。第二混合工程で用いられた袋の寸法は、205×300mmであった。この袋はPE(ポリエチレン)から作製されていた。熱硬化性樹脂、硬化剤、硬化促進剤及びワックス粉を袋に入れて、袋を閉じた。袋を両手で3分間振って袋の内容物を混合することにより、樹脂混合物を得た。熱硬化性樹脂、硬化剤、硬化促進剤及びワックス粉其々の質量及び組成は、以下に示される。下記のNC3000‐H及びNC3000のいずれも、エポキシ樹脂である。
90.9gの熱硬化性樹脂(日本化薬株式会社製のNC3000‐H)
39.0gの熱硬化性樹脂(日本化薬株式会社製のNC3000)
48.2gの硬化剤(フェノールノボラック樹脂、日立化成株式会社製のHP-850N)
2.6gの硬化促進剤(イミダゾール系エポキシ樹脂硬化剤、四国化成株式会社製のC17Z)
15.7gのワックス粉(クラリアントケミカルズ株式会社製のLicowax E)
第二混合物を室温で冷却することより、固形物を得た。
固形物を粉砕することにより、粉末状のコンパウンドを得た。篩を用いた分級に因り、粗大な粒子をコンパウンドから除去した。篩の目開きは2mmであった。
実施例1のコンパウンドをトランスファー試験機に仕込んだ。金型温度175℃、注入圧力4.1MPa、成形時間420秒で、コンパウンドのスパイラルフロー量を測定した。スパイラルフロー量とは、金型に形成された溝内においてコンパウンドが流れる長さである。つまりスパイラルフロー量とは、軟化又は液化したコンパウンドの流動距離である。コンパウンドが流れる溝の形状は、渦巻き曲線(アルキメデスのスパイラル)である。コンパウンドが流動し易いほど、スパイラルフロー量は大きい。つまり、流動性に優れたコンパウンドのスパイラルフロー量は大きい。トランスファー試験機としては、株式会社小平製作所製の100KNトランスファー成型機(PZ‐10型)を用いた。金型としては、ASTM D3123に準じたスパイラルフロー測定用の金型を用いた。実施例1のスパイラルフロー量は、下記表1に示される。
トランスファー試験機及び金型を用いて、実施例1のコンパウンドからトロイダル状の成型体が作製された。金型温度は175℃であり、注入圧力は4.1MPaであり、成形時間は420秒であった。成型体の寸法は、外径20mm、内径12mm、厚み2mmであった。トランスファー試験機としては、株式会社小平製作所製の100KNトランスファー成型機(PZ‐10型)を用いた。金型としては、トロイダル形状を得られる金型を用いた。一次側巻線を上記成型体に5ターン巻回し、二次側巻線を上記成型体に5ターン巻回した。以上の方法によって作製されたサンプルの比透磁率μSを測定した。実施例1の比透磁率μSは、下記表1に示される。比透磁率μSの測定には、岩崎通信機株式会社製のB‐Hアナライザ(SY-8258)を用いた。比透磁率の測定時の周波数は1MHzであった。
第一混合物及び樹脂混合物の質量比の変更により、実施例2のコンパウンドにおける金属フィラーの含有量は、95.0質量%に調整された。金属フィラーの含有量を除いて実施例1と同様の方法で、実施例2のコンパウンドが作製された。実施例1と同様の方法により、実施例2のコンパウンドのスパイラルフロー量が測定された。実施例2のスパイラルフロー量は、下記表1に示される。実施例1と同様の方法により、実施例2のコンパウンドの比透磁率が測定された。実施例2の比透磁率は、下記表1に示される。
比較例1の金属フィラーとして、第二金属粉末のみが用いられた。実施例1と同様に、比較例1のコンパウンドにおける金属フィラーの含有量は、95.5質量%に調整された。金属フィラーを除いて実施例1と同様の方法で、比較例1のコンパウンドが作製された。実施例1と同様の方法により、比較例1のコンパウンドのスパイラルフロー量が測定された。比較例1のスパイラルフロー量は、下記表1に示される。実施例1と同様の方法により、比較例1のコンパウンドの比透磁率が測定された。比較例1の比透磁率は、下記表1に示される。
比較例2の金属フィラーとして、第二金属粉末のみが用いられた。実施例2と同様に、比較例2のコンパウンドにおける金属フィラーの含有量は、95.0質量%に調整された。金属フィラー及びその含有量を除いて実施例1と同様の方法で、比較例2のコンパウンドが作製された。実施例1と同様の方法により、比較例2のコンパウンドのスパイラルフロー量が測定された。比較例2のスパイラルフロー量は、下記表1に示される。実施例1と同様の方法により、比較例2のコンパウンドの比透磁率が測定された。比較例2の比透磁率は、下記表1に示される。
