HEAVY VEHICLE TREADS/UNDERTREAD |
摘要 |
<p>Heavy vehicle tire treads and/or undertread constituted at least in part from a rubber composition comprising between 80 and 100 phr of a natural rubber and between 0 and 20 phr of a synthetic polyisoprene rubber, a reinforcement filler comprising a) between 30 and 50 phr of a highly dispersible silica and b) a carbon black in an amount of between (0.75)C phr and (1.25)C phr as determined by the equation C=−0.8Si+44.3, wherein Si is the amount of the highly dispersible silica, a silane coupling agent and a sulfur curing system comprising between 1.5 and 3 phr of free sulfur and between (0.9)A phr and (L 1)A phr of a sulfenamide accelerator, wherein A is determined by a formula that is a function of the sulfur quantity and the silica weight fraction of the total reinforcement filler.</p> |
