Abstract

The present invention relates to a new type of rubber compound containing light-colored fillers, which is prepared using a new processing aid.

Description

technical field [0001] The present invention relates to new processing active substances for rubber mixtures, in particular rubber mixtures comprising light-coloured fillers, especially silica-containing rubber mixtures, and rubber mixtures containing them, the active substances comprising trimethylolpropane and at least one fatty acids. The rubber mixture has very good processability, but the mechanical properties of the vulcanized rubber mixture are not compromised. Background technique [0002] Mixtures containing silica rubber or tire compounds are more viscous than those containing carbon black, so they can only be processed with difficulty in filling plants for the production of rubber. [0003] DE-A 2 255 577 and DE 4 435 311, EP-A 670 347, US 4,709,605 and WO 00 / 05301 disclose certain polysulfide silanes as reinforcing additives for silica-containing rubber vulcanizates. However, the use of the polysulfide silanes described therein as reinforcing additives for sili...
