| Abstract: |
| The influences of the black N330，N339 and N351 on the heat conductivity of radial tire tread were investigated with orthogonal experiment.The results showed that the influences of 3 types of carbon black on the heat conductivity of tread were in the order of N351＞N339＞N330；the optimum addition levels of black N351，N339 and N330 were 35，35 and 20 phr respectively；the heat conductivity of tread increased with the particle size of the same series black and quite linearly with the temperature；and the heat conductivity of tread increased with the total levels of carbon black. |
