Example Embodiment

[0056] Example 1-Rubber mixture according to the invention:

[0057]

[0058] The first embodiment of the rubber mixture according to the present invention is used to coat textiles, so that the rubberized textile material thus obtained is used to prepare a belt with a rubberized textile layer, as shown in the following table with the rubber mixture according to the present invention. The second embodiment and the comparative example of the traditional glue mixture are compared.

Abstract

The rubberized textile material for a belt textile ply is provided on at least one side of a textile web with a peroxidically crosslinkable ethylene-alpha-olefin-diene terpolymer rubber mixture, preferably an EPDM mixture. In this rubberization mixture the third monomer content (diene content) of the EPDM is preferably at least 4% and the rubber mixture contains: a peroxidic crosslinker, a mineraloil having an aromatics proportion of at least 50 percent by weight and at least one reactive phenol and/or reactive phenol resin capable of binding to the double bonds of unsaturated polymers. The reactive phenol and/or phenol resin and the mineral oil are present in the rubber mixture in a content of altogether 5 to 60 phr. The rubberization has an exceptional manufacturing tack coupled with good adhesion and good dynamic properties.
