The invention relates to a sulfur-crosslinkable rubber mixture, a vulcanizate thereof, and a vehicle tyre. The invention further relates to the use of sulfur-crosslinkable rubber mixtures. The sulfur-crosslinkable rubber mixture contains at least the following components: a) 1 to 30 phf of at least one silane A selected from the group consisting of silanes having the empirical general formulae A-I) and A-XI): A-I) (R1) oSi-R20-(S-R30) m-Sx-(R30-S) m-R20-Si (R1) o; a-XI) (R1) oSi-R2-(S-R3) q-S-X, (R1) oSi-R2-(S-R3) And b) 0.5 to 30 phf of at least one silane B selected from the group consisting of silanes having the empirical general formula B-I), B-01) and B-02): B-I) (R1) oSi-R4-(S-R5) u-S-R4-Si (R1) o; (B-01) (R1) o Si-R10-Si (R1) o; (B-02) (R1) oSi-R9; and c) 12 to 300 phr of silica having a CTAB surface area based on ASTM D 3765 of from 190 to 300 m2/g, preferably from 205 to 270 m2/g, more preferably from 220 to 270 m2/g; and d) at least one diene rubber, where the diene rubber preferably comprises from 5 to 100 phr of polyisoprene, preferably natural polyisoprene (NR), where x is an integer from 2 to 10; and q is 1 or 2 or 3; and u is 1 or 2 or 3; and X is a hydrogen atom or a-C (= O)-R8 group, wherein R8 is selected from the group consisting of hydrogen, a C1-C20-alkyl group, a C6-C20-aryl group, a C2-C20 alkenyl group, and a C7-C20 aralkyl group.

    本发明涉及一种硫可交联的橡胶混合物、其硫化橡胶、以及一种车辆轮胎。本发明进一步涉及硫可交联的橡胶混合物的用途。该硫可交联的橡胶混合物至少含有以下成分:a)1至30phf的至少一种的硅烷A,其选自具有经验通式A‑I)和A‑XI)的硅烷:A‑I)(R1)oSi‑R20‑(S‑R30)m‑Sx‑(R30‑S)m‑R20‑Si(R1)o;A‑XI)(R1)oSi‑R2‑(S‑R3)q‑S‑X;和b)0.5至30phf的至少一种硅烷B,其选自具有经验通式B‑I)、B‑01)和B‑02)的硅烷:B‑I)(R1)oSi‑R4‑(S‑R5)u‑S‑R4‑Si(R1)o;B‑01)(R1)oSi‑R10‑Si(R1)o;B‑02)(R1)oSi‑R9;和c)12至300phr的二氧化硅,其具有190至300m2/g、优选地205至270m2/g、更优选地220至270m2/g的基于ASTM D 3765的CTAB表面积;以及d)至少一种二烯橡胶,其中该二烯橡胶优选地包含5至100phr的聚异戊二烯、优选天然聚异戊二烯(NR),其中x是2至10的整数;并且q是1或2或3;并且u是1或2或3;并且X是氢原子或‑C(=O)‑R8基团,其中R8选自氢、C1‑C20‑烷基、C6‑C20‑芳基、C2‑C20烯基和C7‑C20芳烷基。
