| Abstract: |
| The effect of NBR modified silica on the properties of the tread compound of truck and bus radial tire was investigated.The results showed that，as the addition level of NBR1846 increased，the Mooney viscosity of the tread compound increased， and ts1 and t90 were shortened.When NBR was mixed with silica first，and the addition level of NBR1846 was 8 phr，the vulcanizates showed better physical properties，lower Akron abrasion loss，lower heat build up， higher wet skid resistance and lower rolling resistance.It was found that the modification effect of NBR3305 was better than that of NBR1846. |
