Abstract：Different coupling agents such as Si69,NDZ-105 and KH570 were used for surface treatment of graphite.The curing property,mechanical property,cutting resistance and processing property of the modified graphite-NR composites were studied.The results show that the dispersion of graphite modified by coupling agents in natural rubber matrix are improved,the physical entanglements between graphite and rubber chain are increased.Contrast to unmodified graphite-NR composites,the stress at 100％,stress at 300％ and tensile strength of modified graphite-NR composites is increased obviously and the cutting loss is decreased.The comprehensive properties of KH570 modified graphite-NR composites is the best.The Payne effect of the modified graphite-NR composites is significantly weakened,but the dynamic loss factor is higher than the unmodified graphite-NR composites.
