摘要

This invention relates to a rubber composition comprised of at least one conjugated diene-based elastomer containing triglyceride based algae oil and to a tire with a component thereof.

主权项

1. A rubber composition comprised of, based on parts by weight per 100 parts by weight of elastomer (phr):
(A) at least one conjugated diene-based elastomer, and (B) from about 5 to about 60 phr of triglyceride ester based algae oil, wherein fatty acid components of said triglyceride ester of said algae oil comprise:
(1) about 80 to about 95 percent mono-unsaturated oleic acid component,(2) about 1 to about 5 percent di-unsaturated linoleic acid component,(3) about 2 to about 6 percent palmitic acid component,(4) about 2 to about 6 percent stearic acid component, and (C) from about 30 to about 140 phr of reinforcing filler comprised of:
(1) rubber reinforcing carbon black, or(2) combination of rubber reinforcing carbon black and precipitated silica, (D) silica coupling agent reactive with hydroxyl groups contained on said precipitated silica and another different moiety interactive with carbon-to-carbon double bonds of said conjugated diene-based elastomers.
