| Abstract: |
| The effect of neodymium butadiene rubber（NdBR）/styrene butadiene rubber（SBR） blending on the properties of the tread compound of steel-belted radial tire was studied. The results showed that the properties of the compound containing three kinds of NdBR（BR9110A，BR9110B and BR CB24） were almost the same，and the heat build-up，cutting resistance and wet skid resistance of the compound could be improved by partially replacing solution styrene-butadiene rubber and NdBR with emulsion styrenebutadiene.By using masterbatch process，the comprehensive physical properties of the compound could be significantly improved，the cutting resistance，crack resistance and wet skid resistance increased，and the rolling resistance decreased. |
