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 acid 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 DEG C and 60 DEG 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 of various types and for producing technical rubber articles.
