APPLICATION OF KY-616 AS MODIFYING ADDITIVE FOR BUTADIENE RUBBER COMPOUND

WIPO Patent Application WO/2016/150142

A1

The present invention provides an application of KY-616 as a modifying additive for a butadiene rubber (BR) compound. In the present invention, KY-616 may be applied to a butadiene rubber compound, and has the surprising technical effect of modifying and improving rubber properties; the processability of the butadiene rubber compound of the present invention is significantly improved, burn-protection capability is enhanced, vulcanization time is prolonged, vulcanization speed is reduced, and the mechanical properties and resistance to thermal oxidative aging of the vulcanized rubber are improved. In BR, the antioxidant KY-616 achieves good resistance to thermal oxidative aging; the mechanical properties and resistance to thermal oxidative aging of vulcanized rubber improve as the amount of KY-616 added is increased, and the oxidation induction time first increases, then tends toward a stable value; the appropriate amount of KY-616 in the BR is 1 phr.
