・表面処理工程
それぞれの部材(樹脂基材)の表面に接着剤を塗布する前に、それぞれの部材に表面処理を施した。この表面処理(フレーム処理)は、Arcogas社製のフレーム処理装置を使用し(ガス流量:3.7L/min、空気流量100L/min)、で、処理速度:800mm/sec、部材までの距離20mm、パス回数1回で行った。
ここで、処理速度とは、フレーム処理の速度であり、具体的には、部材に対してフレーム処理装置を動かした速度(mm/sec)である。部材までの距離とは、フレーム処理装置と部材との距離(mm)である。パス回数とは、フレームを掃引した回数である。例えば、フレームを部材の一端から他端まで1回掃引した場合は、パス回数が1回となる。
・接着剤層形成工程
一方の部材の表面処理を施した表面に、上述のウレタン系接着剤(接着剤4a、4b、4c)を塗布して接着剤層を形成させた。
・貼り合わせ・養生工程
さらに、形成された接着剤層の表面に、他方の部材の表面処理を施した表面を貼り合わせて積層体を成形した。次いで、この積層体を23℃、50%RHの条件下で3日間静置することで接着剤層を硬化させて、それぞれの試験サンプルを得た。
