TREAD FOR HEAVY VEHICLE TIRES |
摘要 |
<p>A heavy vehicle tire tread constituted from a material based upon a rubber composition, the composition comprising, per 100 parts by weight of elastomer, between 35 and 60 phr of a solution polymerized styrene-butadiene rubber having a styrene content of between 10 wt. % and 35 wt. % and between 35 and 60 phr of a polybutadiene. The composition may further include between 45 and 110 phr of silica and between (1.94×10−3/n)(S) and (2.55×10−3/n)(S) moles of a sulfur-containing organosilicon compound as a silane coupling agent per 1 kg of the silica, wherein n is a number of silicon atoms in a molecule of the silane coupling agent and S is a CTAB surface area in m2/g of the silica. The rubber composition may be cured with a sulfur curing system comprising a sulfenamide accelerator and between 0.3 and 0.8 phr of free sulfur, wherein a ratio of the sulfenamide accelerator and the sulfur is between 2 and 7.</p> |
