中文摘要:
      试验研究抗硫化返原剂SR534对NR胶料性能的影响，并与抗硫化返原剂PK900进行对比。结果表明，抗硫化返原剂SR534用量不超过2份时，NR胶料的MH、焦烧时间和t90变化不大；随着抗硫化返原剂SR534用量的增大，NR胶料的硫化返原率减小，抗硫化返原性能提高。抗硫化返原剂SR534和PK900用量相同时，SR534的抗硫化返原性能优于PK900；胶料过硫化至60 min时，二者均能使NR硫化胶保持较高的物理性能。
英文摘要:
      The effects of the anti-reversion agent SR534 on the properties of NR compound were experimentally investigated and compared to those of anti-reversion agent PK900.The results showed that MH，scorch time and t90 of NR compound changed a little when the addition level of the anti-reversion agent SR534 was less than 2 phr；the reversion percentage of NR compound was decreased，the anti-reversion characteristic was improved as the addition level of the anti-reversion agent SR534 increased.The anti-reversion characteristic of SR534 was better than that of PK900 with the same addition amount；the anti-reversion agent SR534 and PK900 could be used to improve the physical properties of NR vulcanizate when the cure time was up to 60 min.
