| Abstract: |
| The application of wet mixed silica masterbatch in the tread compound of all-steel off-theroad radial tire was studied. The results showed that compared with the traditional dry mixed silica compound and vulcanizate，the mixing energy consumption and Mooney viscosity of the compound using wet mixed silica masterbatch decreased，the vulcanization characteristics were almost the same，the hardness and tensile properties of the vulcanizate were similar，but the wear resistance，tear resistance and cutting resistance were improved，and the compression heat build-up and rolling resistance decreased. Furthermore，the anti-chipping performance of the finished tire tread compound using wet mixed silica masterbatch was improved. |
