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. |
