Description
すなわち、本発明は、
(1)下記(A)〜(D)を含有してなるアクリルゴム組成物である。
(A)エポキシ基含有アクリルゴム
(B)下記一般式(1)で示されるイミダゾール化合物
(C)pH5.5〜9.0のシリカ
(D)下記一般式(2)で示されるシランカップリング剤
(2)本発明のアクリルゴム組成物は、エポキシ基含有アクリルゴム100質量部に対して、シリカを20〜80質量部含有するものが望ましい。
(3)エポキシ基含有アクリルゴム100質量部に対して、一般式(1)で示されるイミダゾール化合物を0.1〜5質量部含有させることもできる。
(4)エポキシ基含有アクリルゴム100質量部に対して、一般式(2)で示される化合物を0.1〜2質量部含有させることもできる。
(5)シランカップリング剤としては、ジエトキシエチル基含有シランカップリング剤と、ジメトキシフェニル基含有シランカップリング剤と、ジメトキシメチル基含有シランカップリング剤と、ジメトキシブチル基含有シランカップリング剤とからなる群より選択されるいずれか1種以上からなるものを用いることができる。そのシランカップリング剤は、エポキシ基含有アクリルゴム100質量部に対して、0.1〜2質量部含有させることが望ましい。
(6)上記のアクリルゴム組成物を加硫して加硫物を得ることもできる。
(7)更に、上記加硫物を用いて、ホース部品やシール部品を得ることもできる。
耐圧反応容器にアクリル酸ブチル8.8kg、酢酸ビニル3.0kg、部分ケン化ビニルアルコール4質量%の水溶液16kg、酢酸ナトリウム23g、グリシジルメタクリレート0.4kgを投入し、攪拌機であらかじめよく混合し、均一懸濁液を作製した。槽内上部の空気を窒素で置換した後、エチレンを槽内上部に圧入し、圧力を4.3MPaに調整した。攪拌を続行し、槽内を55℃に保持した後、別途注入口より過硫酸アンモニウム水溶液を圧入して重合を開始させた。反応中槽内温度は55℃に保ち、9時間で反応を終了させた。生成した重合液に、ホウ酸ナトリウム水溶液を配合して重合体を固化し、脱水および乾燥を行って、アクリルゴムを得た。得られたアクリルゴムは、n−ブチルアクリレート単量体単位80質量部と、酢酸ビニル15質量部と、エチレン3質量部、グリシジルメタクリレート2質量部の共重合体組成であった。単量体単位成分は核磁気共鳴スペクトルを採取し、各成分を定量した。

引張強度、破断時伸びは、JIS K6251に準拠して測定したものである。すなわち、引張強度は、試験片が破断する時の最大引張力(MPa)である。破断時伸び(切断時伸び)は、試験片が破断した時の伸びであり、初期に対する比率(%)で表す。また、硬さ(硬度)は、JIS K6253に準拠してデュロメータ硬さ計を用いて測定したものである。圧縮永久歪みはJIS K6262に準拠して測定したものである。すなわち、圧縮永久歪みは、150℃で70時間圧縮変形させ、圧縮変形を起こす力を取り除いた後に残存する変形の量(%)である。
