Deformation behaviors of nitrile rubber vulcanizates as studied by pulsed NMR: Effects of carbon black fillers.

Kenzo Fukumori; Norio Sato; Toshio Kurauchi

伸長状態下でのスピンースピン緩和時間(T2)の測定を行い, 一定伸長下の応力緩和特性と対応づけて, ニトリルゴム(NBR)の変形に伴うゴム網目鎖の分子運動性と不均質性の変化を調べた. NBR系のT2信号は, 2成分(Short, Long)に分離できた. Short T2成分は分子運動が拘束された架橋点近傍のゴム網目鎖の領域に対応し, ゴム網目鎖の変形挙動を直接特徴づけていることがわかった. Short T2成分の成分量は変形とともに徐々に増加し, 架橋点による拘束領域の広がりを反映していると考えられる. カーボン配合系では, 粒子充てん量の増加とともにその増加挙動はむしろ抑制され, ゴム-粒子間の相互作用を通じた種々の応力緩和機構に伴うエネルギー損失挙動と対応していると推定された. 更に, カーボン配合系のゴム網目鎖の分子運動性と巨視的な変形との関係において, ひずみ増幅作用の仮定が有用な近似であることが明らかになった.

Bumper recycling technology

Norio Sato; Hidero Takahashi; Toshio Kurauchi

The necessity to develop an appropriate technology for the recycling of automotive plastic parts has become a key issue in recent years, in terms of environmental protection and preservation of resources. It is obvious that plastics recycling in the automotive industry will focus on bumpers, which are relatively large, and can be dismantled into their constituents easily.
