CROSS-LINKABLE RUBBER COMPOSITION FOR SEAL MATERIAL USED AT OILFIELD OR GAS WELL AND SEAL MATERIAL |
摘要 |
A cross-linkable rubber composition for a seal material which is used at an oilfield or gas well comprising a nitrile group-containing copolymer rubber which contains α,β-ethylenically unsaturated nitrile monomer units 10 to 60 wt % and has an iodine value of 120 or less, an α,β-ethylenically unsaturated carboxylic acid metal salt (B), and an organic peroxide cross-linking agent (C) is provided. According to the present invention, it is possible to provide a rubber composition which is excellent in shapeability, is high in durability against hydrogen sulfide and other corrosive gases, and is suitable for application as a seal material which is used at an oilfield or gas well. |

1. A method of use of a cross-linkable rubber composition as a seal material which is used at an oilfield or gas well and is used in an environment with a ratio of hydrogen sulfide of 1 volume ppb to 50 vol %, wherein
the cross-linkable rubber composition comprises a nitrile group-containing copolymer rubber (A) which contains α,β-ethylenically unsaturated nitrile monomer units 10 to 60 wt % and has an iodine value of 120 or less, an α,β-ethylenically unsaturated carboxylic acid metal salt (B), and an organic peroxide cross-linking agent (C). |
