RUBBER COMPOSITION FOR FLEXIBLE COUPLING

摘要

Disclosed is a rubber composition for flexible coupling. In particular, the rubber composition for flexible coupling is prepared by mixing a filler including an HNBR alloy and carbon blacks having different average particle diameters with a hydrogenated acrylonitrile-butadiene rubber such that performance deterioration due to hydrolysis can be prevented even in hot and humid environments and the rubber composition has superior heat resistance and improved mechanical strength.

主权项

1. A rubber composition for flexible coupling comprising:
a rubber component comprising an amount of about 60 to 80% by weight of a hydrogenated acrylonitrile-butadiene rubber and 20 to 40% by weight of an HNBR alloy, % by weight based on the total weight of the rubber component; an amount of about 60 to 180 parts by weight of a filler based on 100 parts by weight of the rubber component; an amount of about 0.1 to 5 parts by weight of a hardener based on 100 parts by weight of the rubber component; an amount of about 0.1 to 5 parts by weight of an accelerator based on 100 parts by weight of the rubber component; an amount of about 1 to 30 parts by weight of a crosslinker based on 100 parts by weight of the rubber component; an amount of about 0.1 to 10 parts by weight of a processing aid based on 100 parts by weight of the rubber component; and an amount of about 1 to 30 parts by weight of a plasticizer based on 100 parts by weight of the rubber component.
