Rubber mixture and vehicle tires
The invention relates to a rubber mixture and to a motor vehicle tire. The rubber mixture comprises the following constituents: at least one rubber and at least one reinforcing filler and 0.5 to 10 phr of at least one hydrocarbon wax composition, where the hydrocarbons in the wax composition have 15 to 110 carbon atoms and where: a) 25% to 40% of the hydrocarbons are linear hydrocarbons having 20 to 30 carbon atoms; and where inter alia b) 5% to 18% of the hydrocarbons are linear hydrocarbons having 31 to 38 carbon atoms; and where inter alia c) 25% to 40% of the hydrocarbons are linear hydrocarbons having 39 to 60 carbon atoms, where the percentage in each case is based on the total number of hydrocarbons having 15 to 110 carbon atoms. The motor vehicle tire comprises the rubber mixture at least in an outer component.
1. A rubber mixture comprising at least the following constituents:
at least one rubber;
at least one reinforcing filler; and,
0.5 to 10 phr of at least one hydrocarbon wax composition, wherein the hydrocarbons in the wax composition have 15 to 110 carbon atoms and wherein:
a) 25% to 40% of the hydrocarbons are linear hydrocarbons having 20 to 30 carbon atoms; and wherein
b) 5% to 18% of the hydrocarbons are linear hydrocarbons having 31 to 38 carbon atoms; and wherein
c) 25% to 40% of the hydrocarbons are linear hydrocarbons having 39 to 60 carbon atoms; and wherein
d) 5% to 15% of the hydrocarbons are branched hydrocarbons having 21 to 31 carbon atoms; and wherein
e) less than 5% of the hydrocarbons are branched hydrocarbons having 32 to 39 carbon atoms; and wherein
f) 5% to 15% of the hydrocarbons are branched hydrocarbons having 40 to 61 carbon atoms;
wherein the percentage in each case is based on the total number of hydrocarbons having 15 to 110 carbon atoms.
2. The rubber mixture as claimed in claim 1 , wherein the rubber mixture comprises at least one diene rubber selected from the group consisting of synthetic polyisoprene, natural polyisoprene (NR), styrene-butadiene rubber (SBR) and polybutadiene (BR).
3. The rubber mixture as claimed in claim 1 , wherein 26% to 37% of the hydrocarbons are linear hydrocarbons having 20 to 30 carbon atoms.
4. The rubber mixture as claimed in claim 1 , wherein 26% to 37% of the hydrocarbons are linear hydrocarbons having 39 to 60 carbon atoms.
5. The rubber mixture as claimed in claim 1 , wherein 10% to 30% of the hydrocarbons in the hydrocarbon wax composition are branched hydrocarbons.
6. The rubber mixture as claimed in claim 1 , wherein the rubber mixture comprises at least one carbon black as reinforcing filler.
7. The rubber mixture as claimed in claim 6 , wherein the rubber mixture contains 25 to 55 phr of at least one carbon black.
8. The rubber mixture as claimed in claim 6 , wherein the rubber mixture contains 60 to 85 phr of at least one carbon black.
9. A motor vehicle tire comprising at least one vulcanizate of at least one rubber mixture as claimed in claim 1 , and wherein the at least one vulcanizate is comprised in at least one outer component of the motor vehicle tire.
10. The motor vehicle tire as claimed in claim 9 , wherein the at least one outer component is at least a sidewall and/or a flange profile.
