Abstract
A sulfur-crosslinked rubber mixture, in particular for vehicle tires, and a vehicle tire. The sulfur-crosslinked rubber mixture contains at least the following constituents: at least one diene rubber and 0.5 to 10.0 phr of at least one anti-reversion agent and 2.0 phr or more of at least one para-phenylenediamine and 2.0 phr or more of at least one dihydroquinoline and wherein the network node spacing of the crosslinked rubber mixture is 4.5 to 10 nm.
Claims24
A sulfur-crosslinked rubber mixture comprising:
- at least one diene rubber,
- 0.5 to 10.0 phr of at least one anti-reversion agent, wherein the anti-reversion agent is selected from the group consisting of 1,6-bis(N,N-dibenzylthiocarbamoyldithio)hexane, and hexamethylene-1,6-bis(thiosulfate) disodium salt dihydrate,
- 2.0 phr or more of at least one para-phenylenediamine,
- 2.75 phr to 10 phr of at least one dihydroquinoline, and
- a vulcanization system having at least one accelerator and elemental sulfur, the at least one accelerator being in an amount of 0.1 to 0.5 mol of accelerator per mol of sulfur atoms,
- wherein the network node spacing of the sulfur-crosslinked rubber mixture is from 4.5 to 10 nm, where the network node spacing is determined by differential scanning calorimetry.
