RUBBER COMPOSITION WITH LOW RESIN CROSSLINKING

摘要

A tire component comprising a rubber composition having a highly unsaturated diene elastomer and a reinforcing filler with a methylene acceptor selected from 3-hydroxydiphenyl- amine, 4-hydroxydipheyl- amine or combinations thereof. Such rubber compositions further include a methylene donor, wherein a ratio of the methylene acceptor to the methylene donor may be greater than 10:1 or in other embodiments greater than 10:1 but no more than 50:1 or between 15:1 and 30:1. A method for manufacturing a tire component includes mixing together components of a rubber composition into a non-productive mix, the components including a highly unsaturated diene elastomer, a reinforcing filler and a methylene acceptor selected from 3-hydroxydiphenylamine, 4-hydroxydipheyl-amine or combinations thereof; and mixing a methylene donor and a vulcanizing agent into the non-productive mix to convert the non-productive mix to a productive mix.
