Rubber mixtures for producing highly reinforced vulcanisates with low damping behaviour

Abstract

The rubber mixtures according to the invention consisting of a rubber, a filler and a specific sulphurized mineral oil are suitable for producing shaped vulcanizates, in particular for producing tires with reduced rolling resistance and high resistance to wet skidding, and tires with particularly reinforced side walls (“run flat tires”).

1 . Rubber mixtures consisting of a rubber, a filler and 0.1 to 75 parts by weight, based on 100 parts by weight of rubber, of a sulphurised mineral oil, wherein the sulphurised mineral oil is obtained by reacting an aromatic-containing mineral oil with sulphur.  
     
     
         2 . Rubber mixtures according to  claim 1 , characterised in that the sulphurised mineral oil has a bound sulphur content of 2.5 to 12.5 wt. %, a glass transition temperature of −25 to −65° C. and a density of 0.85 to 1.1 g/cm 3 .  
     
     
         3 . Use of the rubber mixtures according to the invention and according to  claim 1  for producing shaped vulcanisates, in particular for producing tires with reduced rolling resistance and high resistance to wet skidding and tires with particularly reinforced lateral walls (“run flat tires”).
