| titleOfInvention | Rubber composition, especially for tyre treads |
| abstract | a) 60-100 pphr Naturkautschuk (NR) und/oder synthetisches Polyisopren (IR) mit einemncis-1,4-Anteil > 90 Molprozent, b) 5-35 pphr aktivierte Kieselsäure, wobei der Aktivierungsgrad bezogen auf dienOberfläche der Kieselsäure ≤ 40% beträgt, c) 10-75 pphr Ruß, wobei der Füllstoffanteil von b) und c) 45-80 pphr beträgt, d) 0-40 pphr zumindest eines weiteren Dienelastomers, e) weitere übliche Zusatzstoffe und Vernetzungschemikalien,nwobei die Kautschukmischung im vulkanisierten Zustand einenHochgeschwindigkeitsreißenergie ≥ 12 MJ/m 3 und einen Spannungswert 300 % 10-16nMPa aufweist. The invention relates to a sulfur-crosslinkable rubber mixture, in particular for tire treads. In order to provide rubber mixtures which reduce the formation of cracks (injuries), scales or breakouts when driving over sharp or pointed / round objects in the vulcanized tire tread, it is proposed that the sulfur-crosslinkable rubber mixture contains at least the following components: a) 60-100 pphr natural rubber (NR) and / or synthetic polyisoprene (IR) with a cis-1.4 content> 90 mole percent, b) 5-35 pphr activated silica, the degree of activation based on the surface of the silica being ≤ 40%, c) 10-75 pphr carbon black, the filler content of b) and c) being 45-80 pphr, d) 0-40 pphr of at least one other diene elastomer, e) further conventional additives and crosslinking chemicals, the rubber mixture in the vulcanized state having a high-speed tensile energy ≥ 12 MJ / m 3 and a tension value of 300% 10-16 MPa. |
