Title (EN) HEAVY VEHICLE TREADS/UNDERTREAD
(FR) BANDES DE ROULEMENT/SOUS-CHAPE POUR VÉHICULE POIDS LOURD
Abstract:
(EN) 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 l)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.
(FR) L'invention porte sur une bande de roulement et/ou une sous-chape de pneu de véhicule poids lourd, constituée au moins en partie d'une composition de caoutchouc contenant entre 80 et 100 phr d'un caoutchouc naturel et entre 0 et 20 phr d'un caoutchouc de poly-isoprène synthétique, une charge de renfort contenant a) entre 30 et 50 phr d'une silice hautement dispersible et b) un noir de carbone dans une quantité entre (0,75)C phr et (1,25)C phr, telle que déterminée par l'équation C = -0,8Si + 44,3, Si étant la quantité de la silice hautement dispersible, un agent de couplage de silane et un système de durcissement à base de sulfure contenant entre 1,5 et 3 phr de sulfure libre et entre (0,9)A phr et (L 1)A phr d'un accélérateur de sulfénamide, A étant déterminé par une formule qui est une fonction de la quantité de sulfure et de la fraction massique de silice de la charge de renfort totale.
