Rubber mixture crosslinkable with sulfur useful for manufacture of automobile tires and vibration dampers, contains an acid activated silicate layer and reduces the roll resistance and thus the petrol consumption of automobile tires

摘要

A rubber mixture crosslinkable with sulfur containing: (a) at least one diene-polymer or copolymer; (b) at least one finely divided acid activated silicate layer as strengthening additive; and (c) at least one coupling agent having group reactive towards the filler. Independent claims are included for: (1) preparation of the rubber mixture by mixing of the diene polymer or copolymer (a) and strengthened filler (b) with the coupling agent (c) and/or optionally a masterbatch-mixture and optionally with other, conventional additive, but not vulcanization chemical agents, using conventional mixing aggregate at a temperature of 105-150 deg C; (2) a profiled body, especially an automobile tire or parts of it, gummed beds, conveyor belts, hoses, and sealing elements obtained from the rubber mixture.
