Description
[脂肪酸の起源]
・ゴム組成物に加工助剤として配合するステアリン酸等の脂肪酸又はその化合物
・ゴムポリマー中の残査として存在する脂肪酸
[亜鉛の起源]
・硫黄加硫系のゴム組成物では加硫促進助剤として必須の配合である亜鉛華(酸化亜鉛)
・燃料回路に用いられる真鍮(銅亜鉛合金)製のパイプやジョイントの亜鉛成分
[ゴム組成物のポリマー]
内管用のゴム組成物のポリマーは、燃料透過性、耐燃料性、耐オゾン性、低温性等の基本性能を得るために、NBR(アクリロニトリル−ブタジエンゴム)又はH−NBR(水添−アクリロニトリル−ブタジエンゴム)とする。ガソリン等の燃料透過性の要求に合わせて、NBRにおけるAN(アクリロニトリル)量を変更できる。また、NBR又はH−NBRに、本発明の目的を損なわない範囲で、他のポリマーをブレンドして用いることができる。このような他のポリマーとしては、ACM(アクリルゴム)、NR(天然ゴム)、IR(イソプレンゴム)などのイソプレン系ゴム、BR(ブタジエンゴム)、SBR(スチレン−ブタジエンゴム)、CR(クロロプレンゴム)などの共役ジエン系ゴム、PVC(ポリ塩化ビニル)等を挙げることができる。これらのうち、特にACM又はPVCをブレンドすると、前記基本性能を高めることができる。
酸化マグネシウムは、高活性の酸化マグネシウムが最も好ましい。酸化マグネシウムの配合量は、ポリマー100部に対して1〜3部とする。
活性亜鉛華は、湿式法の中でドイツ法といわれる製法で製造された比表面積の大きい亜鉛華である。具体的には、硫酸亜鉛又は塩化亜鉛の水溶液に塩基性液(ソーダ灰溶液等)を加えてできる白色の塩基性炭酸亜鉛の沈殿を水洗乾燥後か焼して製造される。活性亜鉛華の配合量は、ポリマー100部に対して1〜5部が好ましく、2〜3部がより好ましい。
さらに、ゴム組成物はフィラー(充填材)を配合したものが好ましい。フィラーとしては、特に限定されないが、ガラス繊維、アラミド繊維等の繊維状フィラーや、タルク、マイカ、ワラステナイト、ゼオライト、クレイ、シリカ、黒鉛等の非繊維状フィラーを例示でき、特にタルク、マイカ等の板状フィラーが好ましい。その他、ゴム補強剤、可塑剤、軟化剤、老化防止剤、加硫促進剤、有機過酸化物、架橋助剤、着色剤、分散剤、難燃剤などの添加剤を、本発明の目的を損なわない範囲で配合することができる。
[ポリマー単体からの析出物]
実施例1に使用する、次の表1に示す3種類のH−NBRの各ポリマー単体について析出試験を行い、析出物の有無及び量を確認した。具体的には各ポリマー単体を2×10×10mmの小片にしその18gについて、軽油(TD99−21)75mlのみに浸漬したサンプルと、軽油(TD99−21)75mlに真鍮板とともに浸漬したサンプルとを作成し、これらのサンプルを恒温槽にて80℃で3日間保持した後に冷却し、その軽油を計量管に入れ、遠心分離機(1000rpm×30分)にかけて析出物を分離し、計量管の目盛にてその析出物(沈殿物)の体積%を測定した。表1のとおり、各ポリマー単体を軽油のみに浸漬した場合でも、微量ではあるが析出物(物質は不明)が生成された。また、各ポリマー単体を真鍮板とともに軽油に浸漬した場合には、微量の脂肪酸亜鉛が析出した。
実施例1は硫黄加硫系のゴム組成物によるものである。次の表2及び表3に示す実施例1(1−1〜1−13)及びその比較例1の各配合のゴム組成物を混練して作成し、各ゴム組成物により2mm厚の試験板を成形してこれを加硫した。そして、各試験片について次の測定を行い、結果を表2及び表3に併記した。なお、酸化マグネシウムの配合量が5部である実施例1−1,1−2,1−7ないし1−13と、酸化カルシウムを配合した実施例1−5と1−6は、本発明の範囲外の参考例である。
2.キュラスト:成形温度での加硫時間(T90)及び加硫時の剛性(架橋密度)を判断できるMHを求めた。
3.常態物性:加硫後の試験板について、タイプAデュロメータ硬さ(HS)と、引張強さ(TB)と、伸び(EB)と、100%モジュラス(M100)とを測定した。
4.燃料浸漬試験:加硫後の試験板を2×10×10mmの小片にし、その18gを真鍮板とともに軽油(TD99−21)75mlに浸漬し、これを恒温槽にて80℃で3日間保持した後に冷却し、その軽油を計量管に入れ、遠心分離機(1000rpm×30分)にかけて析出物を分離し、計量管の目盛にてその析出物(沈殿物)の体積%を測定した。
実施例2はパーオキサイド系のゴム組成物によるものであり、いずれも本発明の範囲外の参考例である。次の表4に示す実施例2(2−1〜2−5)及びその比較例2の各配合のゴム組成物を混練して作成し、各ゴム組成物により2mm厚の試験板を成形してこれを加硫した。そして、各試験片について次の測定を行い、結果を表4に併記した。
5.耐熱性:JISK6257に準拠し、120℃×70時間熱劣化後の硬度変化(ΔHS)、引張強度変化(ΔTB)、伸び変化率(ΔEB)を測定した。
6.耐燃料油性:JISK6258に準拠し、試験液(イソオクタン/トルエン=40/60)にサンプルを浸漬させ、40℃×48時間後の(ΔHS)、体積変化(ΔV)を測定した。
7.圧縮永久歪:JISK6262に準拠し、JIS規定(圧縮永久歪測定用テスト)のピースに25%の圧縮歪をかけ、125℃×24時間後に歪みを解放し、30分後に厚さを測定した。
8.低温性:JISK6261に準拠し、低温衝撃試験機を使用して材料の無破壊温度を測定した。
