Abstract
【解決手段】 シリコーンゴムにマグネタイトを配合し、さらに酸化亜鉛を配合して変色を防止したマグネタイト含有シリコーンゴム組成物とする。シリコーンゴム100重量部にマグネタイトを100〜1000重量部を配合し、さらに酸化亜鉛を1〜100重量部配合して変色を防止することが好ましい。
【選択図】 図1
Description
本発明には、多様なシリコーンゴム組成物が好ましく使用できる。シリコーンゴム組成物とは、ポリオルガノシロキサンであり、ジメチル系シロキサン、フェニル系シロキサンのミラブル型と称されるものが特に好適であり、これらのシリコーンゴム1種または2種類以上組み合わせたものが使用できる。また、液状シリコーンゴムも本発明のシリコーンゴムとして使用できる。
酸化亜鉛以外の金属酸化物、具体的には、酸化マグネシウム、水酸化カルシウム、酸化チタン、酸化セリウム、水酸化セリウム、炭酸カルシウムなどを配合処方した場合には、十分な変色防止効果が得られなかった。
また、1次加硫(160℃)後のサンプルと2次加硫(200℃)後のサンプルの表面状態をパワーハイスコープ(株式会社ハイロックス社製)により、サンプルシートの表面を20倍に拡大して撮影・観察して評価した。実施例の1次加硫後のサンプルを図2に、2次加硫後のサンプルを図3に示す。比較例1の1次加硫後のサンプルを図4に、2次加硫後のサンプルを図5に示す。比較例2の1次加硫後のサンプルを図6に、2次加硫後のサンプルを図7に示す。
Claims (3)
- シリコーンゴムにマグネタイトを配合し、
