| 中文摘要: |
| 研究新型纳米碳材SG6和G65替代炭黑N660在丁基橡胶（IIR）内胎胶料中的应用。结果表明：炭黑N660/新型纳米碳材并用（总用量为70份）的IIR混炼胶的门尼粘度降低，加工性能提高，整体硫化速度相当；炭黑N660/SG6并用（并用比为35/35和60/10）的IIR硫化胶的各项物理性能均可达到内胎产品要求，透气率减小20%以上；以70份G65全替代炭黑N660和以80份G65增量替代炭黑N660用于IIR内胎胶料，可满足内胎产品的物理性能和气体阻隔性能要求；新型纳米碳材价格较炭黑至少低20%，可有效降低IIR内胎生产成本。 |
| 英文摘要: |
| The application of new nano carbon materials SG6 and G65 to replace carbon black N660
in isobutene-isoprene rubber（IIR） inner tube compound was studied.The results showed that the Mooney
viscosity of IIR compound with carbon black N660/new nano carbon material blend（total amount was 70
phr） decreased，the processability was improved，and the overall curing speed was the same.The physical
properties of the IIR vulcanizates with carbon black N660/SG6 blends（the blending ratios were 35/35 and
10/60） could meet the performance requirements of the inner tube product，and the permeability was reduced
by more than 20%.Replacing all carbon black N660 with 70 phr G65 or 80 phr G65 in the IIR inner tube
compound，the physical property and gas barrier property of the compounds met requirements of the inner tube
products.The application of the new nanocarbon materials could effectively reduce the production cost of IIR
inner tubes since their price was at least 20% lower than that of carbon black. |
