Effect of bonding systems and antioxidants on the adhesion between EPDM rubber and polyester fabric

Abstract: Ethylene propylene diene monomer (EPDM) rubber mixes containing different types of bonding materials and various commercial antioxidants were used to evaluate the adhesion of EPDM rubber to polyester fabric. A new antioxidant was prepared by graft copolymerization of 1, 5-diaminonaphthalene (DAN) onto natural rubber (NR) in order to investigate its effect on adhesion. It was observed that EPDM mixes containing DAN grafted onto NR shows better adhesion levels than those containing commercial antioxidants. It is also clear that the new system has high resistance towards aging and ionizing radiation. The new NR-g-DAN acts not only to stabilize the rubber mix towards environmental conditions but also to improve adhesion to polyester fabric. [Copyright &y& Elsevier]
