前記発泡ゴム層が、カルボキシル基変性ニトリル系ゴムからなり、且つ該発泡ゴム層の発泡倍率が2.0〜3.0倍であり、エポキシ化合物により架橋されたことを特徴とするガスケット材料。
2.
前記発泡ゴム層が、架橋促進剤として2−エチル−4−メチルイミダゾールをさらに含むことを特徴とする前記1記載のガスケット材料。
3.
前記発泡ゴム層の発泡倍率が2.3〜2.8倍であることを特徴とする前記1又は2記載のガスケット材料。
4.
電子部品のシール部品に用いることを特徴とする前記1〜3のいずれかに記載のガスケット材料。
[カルボキシル基変性ニトリルゴム]
本発明の発泡ゴム層組成物に使用されるゴム組成物ポリマーは、ニトリル系ゴムポリマーの中でも、カルボキシル基変性ニトリル系ゴム(本発明では、カルボキシル基変性ニトリル系ゴムポリマーともいう)であり、カルボキシル基変性アクリロニトリル−ブタジエン共重合ゴムが好ましく用いられる。
本発明において、加硫剤としては、エポキシ化合物が用いられる。エポキシ化合物としては、反応性エポキシ基を2個以上持つ熱硬化性の液状もしくは固体の合成樹脂が用いられ、一般的なビスフェノールA型やビスフェノールF型などのエポキシ樹脂の他、フェノキシ樹脂やビフェニル樹脂、アルキルグリシジルエーテルなどを単独あるいは複数を組み合わせて用いることができる。
発泡剤としては、有機または無機の各種発泡剤または低沸点炭化水素膨張剤を封入した熱膨張性マイクロカプセル等を用いることができるが、独立した発泡構造を得やすい点でマイクロカプセルが好ましい。
カーボンブラックとしては、補強性の高いファーネスブラックあるいはサーマルブラックが用いられる。サーマルブラックを用いた場合、補強性向上以外に、ゴム糊塗工性が良好になるので特に好ましい。ファーネスブラックあるいはサーマルブラックを単独で用いてもよいし、併用することもできる。
無機充填剤は、カーボンブラックと併用して、あるいはカーボンブラックに代えて配合することができる。
老化防止剤としては、イミダゾールやチオウレア等の硫黄元素を含まない一般的な市販品を用いることができる。
以上の発泡ゴム組成物原料の混練は、インタミックス、ニーダ、バンバリーミキサ等の混練機あるいはオープンロールなどを用いて行われる。そして、ゴムコンパウンドは、混練後、沸点250℃以下の溶剤、例えばトルエン等の芳香族炭化水素類、メチルエチルケトンやメチルイソブチルケトン等のケトン類またはこれらの混合溶剤などに溶解または分散させて、固形分濃度が25〜50%のコーティング溶液として調製される。
本発明のガスケット材料は、金属板の片面又は両面に、必要によりプライマー層、接着剤層を介して、上述の発泡ゴム層を積層させたものである。
カルボキシル基変性NBRポリマー(日本ZEON社製「Nipol NX775」、カルボキシル基含有量0.083EPHR※)(※EPHR=Equivalents per hundred) 100重量部
MTカーボンブラック(キャンカーブ社製「サーマックスN990」) 20重量部
ステアリン酸(ミヨシ油脂社製) 2重量部
老化防止剤(住友化学社製「アンチゲン3C」) 3重量部
熱膨張性マイクロカプセル系発泡剤(松本油脂製薬社製「マイクロスフェアーF100D」) 7.5重量部
可塑剤(アジピン酸ジイソデシル(DIDA))(新日本理化社製「サンソサイザーDIDA」) 8重量部
架橋剤(ジャパンエポキシレジン社製「JER828」) 10重量部
ゴムコンパウンドは、トルエン:メチルエチルケトン=9:1混合溶剤に溶解させて、固形分濃度が25重量%のコーティング溶液とした。
次いで、防錆被膜を形成した金属板(SPCC)に、接着剤層を形成した後、ゴムコンパウンドを乾燥後の厚みが150μmになるようにコーティングした後、210℃で3分間加熱空気によりオーブン架橋させ、ガスケット材料を得て、以下の評価を行った。
(1)得られたゴムコンパウンドについて以下の加硫速度の評価を実施した。
[加硫速度](ISO 6502(1999)に対応するJIS K6300−2(2001)準拠)
ロータレスレオメータを用いて加硫速度について評価した。200℃で3分未満にt90以上の加硫度が得られるものを○、3分以上10分未満でt90以上の加硫度が得られるものを△、それ以上もしくは加硫しないものを×とした。
[発泡倍率]
既述のガスケット素材作製方法に基づき素材を作製し、200℃で3分加硫する前の、発泡前と後の厚み変化から発泡倍率を算出した。すなわち、発泡前が65μmで発泡後は150μm厚であった場合には、本評価による発泡倍率は2.5倍である。
[金属腐食性]
密閉したガラス容器の中に、指標となる銀板、銅板(それぞれ15mm×15mm、厚さ1mm)とガスケットサンプルを密閉して、室温にて3か月放置し、指標の金属が変色するかどうかを確認した。
変色したものを×、変色しなかったものを○とした。
また、X線によって硫黄元素が存在するかどうかについても確認し、変色しなくても硫黄元素が検出されたものについては△と評価した。
[初期シール性]
低面圧下(100kPa)での空気リーク量を測定した。
リーク量が多かったものを×、リーク量が少なかったものを○とした。
[軸力測定]
ボルトの軸力測定として応力緩和試験(JIS K6263に準拠)を実施し、そこからガスケット素材の全厚変化を求めた。
全厚変化が60%以下のものを○、60〜80%のものを△、80%以上のものを×とした。
[蒸留水浸漬後の接着性]
耐圧容器中で蒸留水100℃、70時間浸漬したあとのガスケットの接着性を描画試験JIS K6894に準拠し、5点満点の評価で評価した。点数が高いほど良好な結果を示す。
[耐熱性](耐空気加熱老化試験)
100℃に設定したギアオーブン中で70時間暴露したあとの硬度変化(DuroメータAでの瞬間値)を評価した。
硬度変化が4ポイント以下を○、5〜6ポイントを△、7ポイント以上を×とした。
