Rubber mixtures containing gels and rubber products of departure of resins of phenol.

摘要

"Rubber mixtures containing gels and rubber products of departure of resins of phenol.The present invention relates to blends of rubber of at least a rubber containing a double bond, additives for gels of rubber.The products of departure of phenol resins or condensation products of phenol / formaldehyde, as resu00f3is or novolacas,And eventually other substances filling and auxiliary staff of rubber and vulcanized and molded rubber articles prepared from the same.Rubber mixtures according to the invention,Stand in the state not cross-linked by good capacity development (viscosity of the composite ml 1 + 4 / 100 198 C 60 me) as well as the state vulcanized by hardness Shore A / 23 198 C 60The elasticities of ripple and high / 23 198 C 60%, as well as a low specific density.The vulcanizate are intended for the preparation of technical rubber articles and for different parts of the construction of the tyres as coatings of cylinders.Coatings of conveyor belts, girdles, screw winding (spinnkopse), fences, cores of golf balls, shoes as well as mixtures of beads, carcasses of tyres.Mixtures of sub tread and side walls of the tyres.The mixtures are particularly suitable for the preparation of the side walls reinforced tyres with properties of functions of emergency ("inserts for run flat tyres).
