| 中文摘要: |
| 研究隐晶质石墨/炭黑并用对乙烯丙烯酸酯胶料性能的影响。结果表明：随着隐晶质石墨和炭黑N550用量的增大，胶料的Payne效应增强，弹性模量增大，硬度、100%定伸应力和撕裂强度增大，拉断伸长率减小；胶料的拉伸强度随着隐晶质石墨用量的增大而减小，随炭黑N550用量的增大而增大；压缩永久变形随隐晶质石墨用量的增大而增大，随炭黑N550用量的增大先减小后增大。当隐晶质石墨用量为5～10份、炭黑N550用量为40～50份时，胶料的邵尔A型硬度大于70度，拉伸强度大于16 MPa，拉断伸长率大于250%，撕裂强度大于27 kN·m-1，压缩永久变形小于20%。 |

| The effect of cryptocrystalline graphite/carbon black on the properties of ethylene acrylate rubber compounds were studied. The results showed that as the addition level of cryptocrystalline graphite and carbon black N550 increased，the Payne effect of the compound was enhanced，the elasticity modulus was increased，the hardness，modulus at 100% elongation and tear strength of the compound increased，and the elongation at break decreased. The tensile strength of the compound decreased with increasing of the addition level of cryptocrystalline graphite，and increased with increasing of the addition level of carbon black N550.The compression set of the compound increased with increasing of the addition level of cryptocrystalline graphite，and decreased at first and then increased with increasing of the addition level of carbon black N550. As the additon level of cryptocrystalline graphite and carbon black N550 was 5～10 phr and 40～50 phr respectively，the Shore A hardness of the compound was greater than 70 degree，the tensile strength was greater than 16 MPa，the elongation at break was greater than 250%，the tear strength was greater than 27 kN·m-1，and the compression set was less than 20%. |
