PROCESSES FOR PREPARING RUBBER BLEND COMPOSITIONS |
摘要 |
<p>Processes for mixing a filler with a rubber blend containing at least one isoprene elastomer and one butadiene elastomer are provided. Preferably, the processes include the steps of: combining elastomers or a blend of elastomers, a carbon black and/or silica filler(s) and a quinone diimine antidegradant in a rubber composition; mixing the rubber composition for a viscosity-reducing effective period of time to reduce the viscosity of the composition; and discharging the mixed composition. The compositions are preferably discharged from the mixing vessel at or near a minimum viscosity occurring at a temperature of about 120 - 160 °C.</p> |
