Abstract: |
The ozone aging process of SIBR was studied,and the changes of its microstructure and surface cracking during the ozone aging were investigated.The results showed that,the content of double bonds in the molecular chain of SIBR decreased and carbonyl group formed during aging.Those changes slowed down in the late stage of aging which was similar to SSBR.The initial cracking times of unfilled and carbon black filled SIBRs were between SSBR and IR, respectively,and their crack growth rate was slower than that of SSBR and IR.Compared with SSBR and IR,the physical property retention of SIBR after ozone aging was higher,indicating better ozone aging resistance. |
