Abstract:
      The effects of the addition level of anti-reversion agent WK-901 on the properties of the compound and finished product of the rubber isolation bearing were studied.The results showed that anti-reversion agent WK-901 had no effect on t10 and t90，but had a significant effect on vulcanization flatness.The anti-reversion agent WK-901 had certain effect on the physical properties of the compound before aging，and had significant effect on the physical properties of the compound after aging.With increase of the addition level of anti-reversion agent WK-901，the hardness and tensile strength of the inner compound of finished rubber isolation bearing increased，the elongation at break decreased，and both the post-yield stiffness and equivalent horizontal stiffness of the bearing increased.
