Abstract: The paper investigates the effect of four different accelerants contained in adhesives, i.e., N-cyclohexyl-2-benzothiazole sulphenamide (CZ), N, N-dicyclohexyl-2-benzothiazole sulphenamide (DZ), dibenzothiazole disulfide (DM) and N, N'-m-phenylene digmaleemide (PDM) on the adhesion of EPDM rubber to metals as well as the effects of their different dosages used on their adhesives. The results indicate that such accelerants contained in adhesives can increase adhesive strength of EPDM rubber to metals. Among them the thiazole accelerants are more effective than imides, but the best one is DM. It is found that the best mass fraction of thiazole is 0.5%, of which the max shear strength is 1.059 MPa.
