| Abstract: |
| The effect of eucalyptus lignin on the aging performance of natural rubber（NR） compound was studied.The results showed that eucalyptus lignin had a delayed effect on the vulcanization of NR compound，and its effect on the vulcanization rate of the compound was between antioxidant 264 and 2246.The protective effect of eucalyptus lignin on the thermal oxidative aging and ozone aging of the compound was superior to antioxidant 264，close to antioxidants 2246 and RD，and inferior to antioxidant 4020.Its protective effect on the UV aging of the compound was better than antioxidant 264 and 2246，comparable to antioxidant RD，but worse than antioxidant 4020.Eucalyptus lignin/antioxidant 4020 blending had an impact on the vulcanization rate of the compound，as the amount of eucalyptus lignin increased，the vulcanization rate of the compound slowed down，but the FL，Fmax－FL and physical properties of the compound did not change significantly.When the blending ratio of eucalyptus lignin/antioxidant 4020 was （0.5～1）∶（1.5～1），its protective effect on the thermal oxidative aging，ozone aging and UV aging of the compound was better，which was similar to that of using antioxidant 4020 alone.The blending of eucalyptus lignin and antioxidant 4020 had a synergistic protective. |
