混練押出・成形
表1、2の配合で原料を混合し、次いで東芝機械(株)製のベント付き2軸押出機「TEM−35B」を用いて溶融混練、ペレット化した。得られたペレットを射出成形機により図−1に示す成形品を成形した。
各種の測定方法及び評価基準は以下のとおりである。
(1)接合強度
上記成形品の箱形成形品の底面中央部に穴を開け、そこからPC板に負荷を加えて、一部が剥離した時点の荷重を全溶着面積で除して、接合強度とした。
(2)気密性評価
上記成形品を、後述する冷熱衝撃試験10サイクルと1000サイクル施した後、80℃の湯中に10分浸漬して、接合面からの空気の漏れの有無により確認。
(3)冷熱衝撃試験
−40℃/30分、120℃/30分を1サイクルとして冷熱試験を行う。
表1に示す樹脂組成物を用いて、PC板をレーザ溶着させた試験片を作成し、上記試験を行った。
表−2に示す組成物を作成し上記試験を行った。
