Rubber mixtures containing silica, carbon black and rubber gel |
摘要 |
The present invention relates to rubber mixtures based on silica and carbon black-filled solution styrene/butadiene rubbers in which the silica has been partially replaced by rubber gels. The vulcanizates produced from the rubber mixtures of the present invention are distinguished by improved cushioning behavior at 0° C. and 60° C., and this is accompanied by better resistance to slipping when wet and improved rolling resistance. In addition, the vulcanizates have good resistance to wear. The processing behavior of the unvulcanized rubber mixtures (compound viscosity and Mooney relaxation) is not impaired by the partial substitution of silica.
