摘要

There is prepared a vulcanizable rubber mixture of a vulcanizable halogen free rubber or a mixture of a halogen free rubber with a maximum of 80% based on the weight of the total rubber of a halogen containing rubber, additionally a silicate filler in an amount of 1 to 250 parts by weight, an oxide of the metal zinc, magnesium or lead in an amount of 0 to 15 parts by weight, a monobasic fatty acid having 12 to 24 carbon atoms in the alkyl chain, benzoic acid or salicylic acid in an amount of 0 to 10 parts by weight, optionally sulphur and/or sulphur donor in an amount of 0.1 to 15 parts by weight, a vulcanization accelerator in an amount of 0.1 to 10 parts by weight, a plasticizer in an amount of 0 to 100 parts by weight, a stabilizer from the group of antiagers, fatigue inhibitors, antioxidants, light protective agents and ozone protective agents in an amount of 0 to 10 parts by weight of each, carbon black in an amount of 0 to 150 parts by weight, optionally additional customary rubber assistants in customary amounts and at least one organosilane in an amount of 0.1 to 20 parts by weight, the silane corresponding to the formula Xp-CmH2m+1-pSiR1n(OR)3-n I in which X is chlorine or bromine, p is 1 or 2, m is 1 to 5, R1 is a C1-C5-alkyl group, C5-C8-cycloalkyl group or the phenyl group, R is a C1-C5-alkyl group, a C5-C8-cycloalkyl group, the methoxyethyl group, the phenyl group or the benzyl group and n is 0, 1 or 2, or a hydrolysate and/or condensate of organosilane I, in which all stated amounts are based on 100 parts by weight of rubber.
