Description
該組成物中のフッ素ゴム100重量部に対して加硫剤が0.5〜1.7重量部であり、かつ該組成物中のフッ素ゴムのムーニー粘度(ML1+20、140℃)が70〜150であるゴム組成物に関する。
得られたフッ素ゴムを8インチロール2本を備えた練りロール機(ロール間隙:約1mm)に3回通してシーティングし、ムーニー粘度測定器(MV2000E ALPHA TECHNOLOGIES社製)を用いて、L型ローターを使用し、140℃で予熱時間1分、測定時間20分にて、JIS K 6300(1994年)に準拠して、測定をした。
装置:HLC−8020(東ソー(株)製)
カラム:GPC KF−806M(昭和カラム 製) 2本

19F−NMR(Bruker社製AC300P型)を用いて測定した。ただし、含TFEポリマーは、19F−NMR(日本電子(株)製FX100型)を用いて測定をした。
実施例および比較例で得られた加硫シートを用いて、タイプAデュロメーター(商品名:ASKER、高分子計器社製)を用いてJIS K6253(1997年)に準拠して測定した。
実施例および比較例で得られた加硫シートを用いて、引張り試験機(テンシロン、オリエンテック社製)を使用して、JIS K6251(1993年)に準じて、500mm/分の条件下で、ダンベル4号を用いて、23℃における引張破断強度および引張破断伸びを測定した。
ASTM D1313(1994年)に準じて、実施例および比較例で得られたP−24・Oリングを、温度280℃、圧縮変形量25%の条件下に72時間放置した後の圧縮永久歪みを測定した。
実施例および比較例で得られたP−24・Oリングを、予め280℃に加温した圧縮装置とスペーサーに仕込み、圧縮率50%、280℃の条件下に1時間保持した後、圧縮装置から取り出し、割れの有無を目視で調べた。合計10個のOリンクについて調べ、下記式より割れ率を求めた。
割れ率(%) = 〔(割れたOリングの数)/10〕×100

攪拌装置として、電磁誘導攪拌装置を有する内容積1.8リットルの重合槽に、純水720g、10重量%のパーフルオロオクタン酸アンモニウム水溶液290g、およびマロン酸ジエチル0.6gを仕込み、系内を窒素ガスで充分置換したのち減圧にした。この操作を3回繰り返し、減圧状態でVdF20gとHFP51gを仕込み、攪拌下に80℃まで昇温した。ついで、純水0.6gに溶解した過硫酸アンモニウム塩(APS)0.02gを窒素ガスにて圧入して重合を開始した。重合圧力を2MPaとし、重合時の圧力低下を補うため、VdF/HFP混合モノマー(78/22(モル%))の連続的に供給し、攪拌下に重合を行った。重合終了までに、215gのモノマーを槽内に供給した。
製造例1同様の電磁誘導攪拌装置を有する内容積1.83リットルの重合槽に、純水977gと製造例1で製造したポリマー粒子の水性分散液10.2gを仕込み、系内を窒素ガスで充分置換したのち減圧にした。この操作を3回繰り返し、減圧状態で、VdF142gとHFP449gを仕込み、攪拌下に80℃まで昇温した。ついでマロン酸ジエチル1.45gと純水15gに溶解したAPS0.08gを窒素ガスにて圧入して重合を開始し、(a)および(b)の条件で重合を継続し、2.9時間後に攪拌を止め、モノマーを放出して重合を停止した。
(a)VdF/HFP(78/22(モル%))モノマー混合物を連続的に供給し、気相部分の圧力を6MPaに維持した。また、重合終了までに、282gのモノマーを槽内に供給した。
(b)攪拌速度を560rpmで維持した。
マロン酸ジエチルを1.80g、APSを0.09gとしたこと以外は、製造例2と同様にフッ素ゴムを重合した。
マロン酸ジエチルを2.0g、APSを0.09gとしたこと以外は、製造例2と同様にフッ素ゴムを重合した。
マロン酸ジエチルを2.80g、APSを0.12gとしたこと以外は、製造例2と同様にフッ素ゴムを重合した。
着火源をもたない内容量48リットルのステンレス製オートクレーブに、純水29リットルおよび乳化剤としてC7F15COONH429gを入れ、系内を窒素ガスで充分に置換したのち、系内の温度を60℃に昇温した。200rpmで攪拌を行いながら、VdFとHFPとTFEとの混合ガスを、VdF/HFP/TFE=56/28/16(モル%)で内圧が15kgf/cm2Gになるように仕込んだ。
内容積3リットルの加圧型ニーダーのジャケットをヒーターで140℃に加熱しながら、製造例2で得られた二元フッ素ゴム4000gを徐々に投入し、その後にBIS−AF
26g、P−21 26gを投入し、12分間混練りした。3分間混練りごとにローターを停止して加圧蓋を解放し、ローター逆回転にてゴムの上下を入れ替え、再度加圧して混練りすることを繰り返した。混練り終了直後のゴム温度は168℃であった。ローターの回転数は、前ブレード33rpm、後ブレード22rpmとした。
製造例2〜6で得られたフッ素ゴムを用い、表2に示した配合条件にした以外は実施例1と同様の方法で、加硫シートおよびP−24・Oリングを得た。
