| 中文摘要: |
| 采用两种方式制备天然气制乙炔副产炭黑并进行性能表征，并将两种副产炭黑与炭黑N660分别添加到天然橡胶（NR）中，考察其对NR胶料性能的影响。研究表明：未压滤副产炭黑的比表面积和结构均大于压滤副产炭黑，但与炭黑N660相比仍有差距；炭黑N660和未压滤副产炭黑胶料的门尼粘度较高且相近，压滤副产炭黑胶料的门尼粘度最低；炭黑N660胶料的邵尔A型硬度、100%定伸应力、300%定伸应力、拉伸强度和撕裂强度最高，未压滤副产炭黑胶料其次，压滤副产炭黑胶料最低；压滤副产炭黑胶料的耐磨性能最差，压缩疲劳温升最高；两种副产炭黑对胶料均具有一定的补强作用，但与炭黑N660相比仍有一定差距；未压滤副产炭黑胶料的分散性能和动态力学性能优于压滤副产炭黑胶料。 |

| The by-product carbon black from natural gas based acetylene production was prepared by two methods and the properties were characterized. The effects of the obtained carbon black on the properties of natural rubber （NR） compound were investigated and compared with carbon black N660. The results showed that the specific surface area and structure of the carbon black without pressure filtration process were larger than those of the carbon black prepared using pressure filtration，and they were still smaller than those of carbon black N660. The Mooney viscosity of the compounds with carbon black N660 and pressure filtrated by-product carbon black were similar and higher than that of the compound with pressure filtrated by-product carbon black. The Shore A hardness，modulus at 100% and 300% elongation，tensile strength and tear strength of the vulcanizate with carbon black N660 were the highest，and those physical properties of the vulcanizate with the carbon black prepared using pressure filtration were the lowest. Moreover，the vulcanizate with pressure filtered carbon black had the worst wear resistance and the highest compression fatigue heat buildup.Both types of by-product carbon black showed certain reinforcing effect on NR compound，but there were still some gaps compared with carbon black N660. The dispersion of carbon black and dynamic mechanical properties of the compound filled by the carbon black without pressure filtration were better than those of the compound filled by the carbon black using pressure filtration. |
