| 中文摘要: |
| 研究废旧轮胎热裂解炭黑（CBp）在低温氟橡胶胶料中的应用，并与炭黑N990对比。结果表明：与炭黑N990填充低温氟橡胶胶料相比，CBp填充低温氟橡胶胶料的焦烧时间延长，交联程度增大；CBp填充低温氟橡胶胶料中填料-填料和填料-橡胶基体相互作用较炭黑N990填充低温氟橡胶胶料强；CBp填充低温氟橡胶硫化胶的硬度和定伸应力较大，但拉伸强度和拉断伸长率较小，而拉伸强度仍能达到15.8 MPa；CBp填充低温氟橡胶硫化胶的耐低温性能稍逊于炭黑N990填充低温氟橡胶硫化胶。 |
| 英文摘要: |
| The application of waste tire pyrolysis carbon black（CBp） in low temperature fluororubber
compound was studied and compared with carbon black N990. The results showed that compared with
low temperture fluororubber compound with carbon black N990，the scorching time of low temperture
fluororubber compound with the CBp was extended，the crosslinking degree was higher，and the fillerfiller
and filler-rubber interactions were stronger. The hardness and tensile stress at a given elongation of
low temperture fluororubber vulcanizate with the CBp were higher，but the tensile strength and elongation
at break were lower，however，the tensile strength could still reach 15. 8 MPa. It was also found that the low
temperature resistance of low temperature fluororubber vulcanizate with the CBp was slightly inferior to that
of low temperture fluororubber vulcanizate with carbon black N990. |
