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 N351N339N330;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.
