Description
本発明のゴム・樹脂の超音波接合方法の好適な態様として、前記樹脂溶融工程において、前記溶融樹脂を前記ゴム部材の前記凹部内へ押し込む量は、0.2〜1.4mmとされている。
また、本発明のゴム・樹脂の超音波接合方法の好適な態様として、前記樹脂溶融工程において、前記超音波振動の発振時間は、0.2〜1.0秒とされている。
図示しない加硫成形型を用いた加硫成形により、EPDMよりなる板状(8mm×40mm、ゴム厚:1.0mm)のゴム部材1を成形した。このとき、加硫成形型の型面に所定のブラスト処理を施しておくことにより、ゴム部材1の外表面全体を100メッシュ以下の面粗度とした。なお、図1において、ゴム部材1の下面が100メッシュ以下のゴム接合粗面10となる。
押し込み量:0.4mm
発振時間 :0.15sec
発振周波数:19.15±0.15Hz
振幅 :18μm
前記実施例1において、樹脂部材2の上面を10μmのシボ加工が施されたシボ加工面として、表面粗さがRz10μmである樹脂接合粗面20とすること以外は、前記実施例1と同様に超音波接合して、ゴム・樹脂接合品を得た。
前記実施例1において、樹脂部材2の上面のシボ加工による粗面処理を無くして、樹脂接合粗面20を平坦な樹脂接合面(表面粗さRz1.2μm)とすること以外は、前記実施例1と同様に超音波接合した。
前記実施例1、2及び比較例で超音波接合したゴム・樹脂接合品について、接合強度を評価した。この評価は、オーレグラフ(引張圧縮試験機、今田製作所(株)社製)を用いて、速度:10mm/分の条件で行った。その結果を表1及び図3に示す。
前記実施例1において、ゴム部材1のゴム厚を0.67mm、0.85mm、1.05mmと変更し、以下に示す条件の超音波接合をして、ゴム厚と接合強度との関係を調べた。その結果を表2及び図4に示す。
押し込み量:0.2mm
発振時間 :1.0sec
発振周波数:19.15±0.15Hz
振幅 :18μm
前記実施例1において、加圧力、押し込み量及び発振時間をそれぞれ種々変更して、接合強度に与える影響を調べた。その結果を表3及び、図5〜図7に示す。
