Description
インサート成形により127mm×13mm、厚み2mmの架橋ポリエチレン製の電線被覆材から構成されたと、実施例及び比較例で得られた127mm×13mm、厚み1.2mmの止水体形成用熱可塑性エラストマー樹脂組成物からなるシートを貼り合わせ、それをT型剥離試験装置(INSTRON製、5567P7529)にて25mm/minの試験速度でピーリング応力(N/cm)を測定し、接着性の指標とした。ピーリング応力が大きいほど、接着性に優れることを示す。
JIS K7206に準拠して、試験荷重10N及び昇温速度50℃/hにてビカット軟化点(℃)を測定し、耐熱性の指標とした。ビカット軟化点が高いほど、耐熱性に優れることを示す。
ASTM D638に準拠して、TypeIV試験片を用い、引張速度50mm/分の条件下で測定される破断時の伸び率(%)を測定し、柔軟性の指標とした。破断伸びが大きいほど、柔軟性に優れることを示す。
ペレット状に成形された下記実施例及び比較例のコネクタ用の止水体を構成するための熱可塑性エラストマー樹脂組成物を用いて、図1に示されたコネクタを製造し、このコネクタをアルミ製の冶具にセットして水中にいれ、冶具にチューブを通して当該チューブから止水部4と電線5との間に10.0kPaの圧縮空気を30秒間送り、止水部4とハウジング部3からの圧縮空気の漏れを観測した。圧縮空気の漏れがない場合、圧縮空気の圧力を10.0kPaずつ200kPaまで上げていった。このとき、漏れが観測されたときの圧縮空気の圧力をシール圧とし、シール圧が100kPa以上のものを十分であるとして合格(符号「○」)、100kPa未満のものを不充分であるとして不合格(符号「×」)とした。ここで、上記シール圧が200kPa以上であれば、止水性に非常に優れると言える。
下記の配合成分を第1表及び第2表に示す割合でドライブレンドした後、二軸押出機を用いシリンダー温度290℃で溶融混練を行い、得られたストランドを水槽を通して冷却した後、ペレット化し、樹脂組成物を調製した。得られた樹脂組成物を用いて上記の物性試験の測定を行った。測定結果を表1に示す。
マレイン酸変性スチレンエチレンブチレンスチレンブロック共重合体:(旭化成ケミカルズ株式会社製、タフテック M1913、スチレン/エチレンブチレン質量比=30/70、MFR(温度230℃、荷重2.16kgf)=5g/10分、酸価=10mgCH3ONa/g)
ホモシンジオタクチックポリスチレン:(出光興産株式会社製、ザレック130ZC、ラセミペンタッドタクティシティー=98%、MFR(メルトフローレート、温度300℃、荷重1.2kgf)=13g/10分)
(1)酸変性されたスチレン系エラストマーに主としてシンジオタクチック構造を有するポリスチレン系重合体(SPS)を添加することによりビカット軟化点が高くなり、耐熱性が向上すると共に、ポッティング法を用いずに、射出成形によって成形することが可能なコネクタ用止水体を構成する熱可塑性エラストマー樹脂組成物、及び、その成形体である止水体を得ることができる。
