Aging-resistant light-permeable composite material for vehicle tires and process for production thereof

A process for producing a vulcanizable composite material, comprising the steps of:

• a) producing or providing a textile strength member,
• b) producing or providing a crosslinkable rubberization mixture comprising:
• i) at least one base rubber selected from the group consisting of ethylene-propylene-diene rubbers and butyl rubbers and
• ii) at least one aging stabilizer selected from the group consisting of p-phenylenediamines, dihydroquinolines, phenylnaphthylamines, substituted phenols and substituted bisphenols and
• c) introducing the textile strength member into the crosslinkable rubberization mixture to obtain the vulcanizable composite material,
• wherein the crosslinkable rubberization mixture is processible by vulcanization to give a crosslinked rubberization mixture which is at least partly transmissive to visible light at least in sections.

A vulcanizable composite material for the production of vehicle tires, comprising:

• at least one textile strength member, and
• a crosslinkable rubberization mixture surrounding the strength member, comprising:
• i) at least one base rubber selected from the group consisting of ethylene-propylene-diene rubbers and butyl rubbers and
• ii) at least one aging stabilizer selected from the group consisting of p-phenylenediamines, dihydroquinolines, phenylnaphthylamines, substituted phenols and substituted bisphenols,
• wherein the crosslinkable rubberization mixture is processible by vulcanization to give a crosslinked rubberization mixture which is at least partly transmissive to visible light at least in sections.
