Process of producing a rubber-extruded article

Abstract

A process for producing a rubber extruded article comprising a main body made of EPDM, by finishing the surface of the article with a cloth-like surface, by attaching cloth to a designated surface of the rubber substrate, said process comprising forming the main body of an extruded article by extrusion while forming a first adhesive layer comprising a blended rubber composed of 40 to 80% by weight of NBR, 20 to 60% by weight of EPDM and 0 to 35% by weight of SBR, or a composition of the blended rubber on the designated surface of the rubber substrate, subjecting the main body of the extruded article to a vulcanization step, and then pressure-bonding a long, narrow strip of cloth lined with a second adhesive layer of a thermoplastic resin to the first adhesive layer, and fusing the second adhesive layer together with the first adhesive layer by heating to cause the complete union of the strip of cloth to the rubber extruded article.
