For the super properties, elastomer materials have been widely using in the fields of industry, agriculture and national defense. But the weakness of aging resistance performance greatly affects its life span and increases the expenses for service. Some intensive research on the additives of antiager and antiozonant is carried out to improve the aging resistance of elastomers. But the property of elastomers aging resistance is not only related with the additives, but also with the curing methods. Radiation crosslinking method for curing the elastomers in this work is employed to modify the mechanical properties of elastomers SBR in order to enhance its aging resistance property.
