Rubber composition and tyres

摘要

Sulfur cross-linkable rubber mixture free of aromatic process oil, preferably for tire tread of pneumatic vehicle tire, comprises a solution polymerized styrene-butadiene-copolymer (30-90 phr); a further diene rubber (10-70 phr); carbon black (5-35 phr); mineral oil plasticizer (1-80 phr) having less than 3 wt.% of polycyclic aromatic compound; a silicic acid (20-100 phr); and a silane-coupling agent (1-15 phr). Sulfur cross-linkable rubber mixture free of aromatic process oil, preferably for tire tread of pneumatic vehicle tire, comprises a solution polymerized styrene-butadiene-copolymer (30-90 phr, weight parts in relation to 100 weight parts of the total rubber mass) with a vinyl-part of more than 35 wt.%, modified with primary amino group and alkoxysilyl group; a further a diene rubber (10-70 phr); carbon black (5-35 phr) with an iodine adsorption index of 100-180 g/kg and a dibutylpthalate (DBP)-index of 100-150cm 3>/100g; mineral oil plasticizer (1-80 phr) having less than 3 wt.% of polycyclic aromatic compound, which is determined by dimethyl sulfoxide extract, according to IPS 346 method; a silicic acid (20-100 phr); and a silane-coupling agent (20-100 phr). An independent claim is included for a pneumatic vehicle tire with a tire tread that is at least partially obtained from sulfur vulcanized rubber mixture.
