| 中文摘要: |
| 研究以隐晶质石墨为主体的复合碳粉在实心轮胎胶料中的应用。结果表明：复合碳粉分别等量替代50%炭黑N660和炭黑N330用于实心轮胎的胎面胶和中间胶，试验配方胶料的物理性能与原配方胶料相当，导热性能提高；与原配方实心轮胎相比，试验配方实心轮胎的生热低，耐久性能更好，使用寿命延长；复合碳粉具有良好的导热性能，可有效降低实心轮胎的胎面温度，可作为具有补强作用的导热填料应用于实心轮胎胶料中。 |
| 英文摘要: |
| The application of the composite carbon powder with aphanitic graphite as the main
component in solid tire compounds was studied. The results showed that by using the composite carbon
powder to replace 50% of carbon black N660 and N330 in the intermediate compound and tread compound
of the solid tire，respectively，the physical properties of the test formula compounds were comparable to the
original formula compounds，and the thermal conductivities were improved. Compared to the original formula
solid tire，the test formula solid tire had lower heat generation，better durability and longer service life. The
composite carbon powder had good thermal conductivity and could effectively reduce the tread temperature
of solid tire，therefore，it could be used as a heat-conducting reinforcing filler in solid tire compounds. |
