摘要： An adhesive material for aging prevention which can eliminate problems of conventional compositions for aging prevention and can prevent a crosslinked rubber from aging; and a method of preventing a crosslinked rubber from aging. The adhesive material for aging prevention comprises 100 parts by mass of at least one polymer ingredient selected from the group consisting of rubbers, thermoplastic elastomers, and resins and 5-50 parts by mass of an antidegradant. The method of preventing crosslinked-rubber aging comprises applying an adhesive material for aging prevention comprising at least one polymer ingredient selected from the group consisting of rubbers, thermoplastic elastomers, and resins and an antidegradant to a crosslinked rubber to allow the antidegradant to migrate to the crosslinked rubber and thereby prevent the crosslinked rubber from aging.
