| 中文摘要: |
| 试验研究二氧化锡、硫酸钡、石墨和白炭黑对四丙氟橡胶耐腐蚀性能的影响。结果表明：4种填料填充的四丙氟橡胶经热氧老化后硬度和拉伸强度增大，经盐酸和气相硫化氢腐蚀后物理性能明显下降；石墨的加入有助于提高四丙氟橡胶的耐盐酸和气相硫化氢腐蚀的能力，石墨的最佳用量为10份。 |
| 英文摘要: |
| The effect of tin dioxide,barium sulfate,graphite and silica on the corrosion resistance of tetrafluoroethylene-propylene rubber was experimentally investigated.The results showed that,the hardness and tensile strength of tetrafluoroethylene-propylene rubber filled by different fillers were increased after thermal-oxidative aging.The physical properties were decreased significantly after HCl and H2S sour gas corrosion.It was found that the corrosion resistance against HCl solution and H2S sour gas could be improved by adding graphite,and the optimal addition level of graphite was 10 phr. |
