RUBBER MIXTURES CONTAINING SILICIC ACID, SOOT AND RUBBER GEL

摘要

The invention relates to rubber mixtures based on silicic acid and styrene/butadiene rubber solutions filled with soot, wherein the silicic aci d is partially substituted by rubber gels. The vulcanised rubber produced from the inventive rubber mixtures is characterised in that has an improved hysteresis quality at 0 ~C and 60 ~C, and at a result an improved anti-slip resistance when wet and an improved resistance to rolling. Furthermore, said vulcanised rubber has a good resistance to abrasion. The processing quality of the unvulcanised rubber mixtures (compound viscosity and Mooney relaxation) does not deteriorate as a result of partial silicic acid substitution. Said inventive rubber mixtures are used for producing tyres and tyre components o f various types and for producing technical rubber articles.
