| 中文摘要: |
| 将淀粉进行表面醚化和酯化疏水改性，研究改性淀粉在胶料中的应用。结果表明：改性淀粉替代部分炭黑对胶料物理性能有一定影响，采用酯醚淀粉替代部分炭黑的胶料物理性能明显优于采用轻质碳酸钙替代部分炭黑的胶料，与白炭黑替代部分炭黑的胶料物理性能接近；改性淀粉与偶联剂KH550和KH570配合的胶料物理性能较好；轮胎胎面胶中用8～10份改性淀粉替代部分炭黑可以明显提高胶料的耐屈挠性能并降低生热。 |
| 英文摘要: |
| In this study，the starch was modified by etherification and esterification methods，and the modified starch was used to replace part of the carbon black in the rubber compounds and the physical properties of the rubber compounds were compared with that by using precipitated calcium carbonate（PCC） or silica to replace part of the carbon black. It was found the physical properties of the rubber compounds were affected by adding modified starch. However，they were much better than those with PCC，and similar to those with silica. With coupling agents KH550 and KH570，the physical properties of the rubber compounds with modified starch were improved. It was also found that by using 8～10 phr of modified starch in the tire tread compound，the flex resistance was significantly improved and the heat buildup was reduced. |
