The effects of different antioxidants on the thermal oxidative aging properties of eucommia ulmoides gum(EUG)/natural rubber(NR) blends were studied.The microstructure,crystallization and melting behavior,thermal stability and mechanical properties of the blends were tested and characterized by SEM,DSC,TGA and universal drawing machine.The results showed that the addition of antioxidant was helpful to the vulcanization and the mechanical properties of the blends were improved;The antioxidant 4010NA had the best protective effect on the combined glue under the condition of thermal oxidative aging.The EUG phase reacted first in the aging process,and 4010NA mainly delayed the further crosslinking of EUG phase network in blends.Thermogravimetric analysis showed that the main molecular chain and crosslinking network of EUG/NR did not appear obvious damage after 24h aging.
