| Abstract: |
| The effect of the blending procedure，the amount of compatibilizer，and the amount and particle size of ground tire on the physical properties of the waste PP/ground tire composite compatibilized with ENR/PP-MAH (maleic anhydride grafted polypropylene) two-component compatibilizer was investigated.The results showed that the chemico-physical bonding between ENR and ground tire formed through the shearing action and the crosslinking with DCP to make ENR/PP-MAH compatibilizer more effective；the impact strength of the resultant composite was 14.1 kJ·m-2 and its tensile strength was 18.5 MPa when the optimal blending procedure，100 parts of PP，20 parts of ground tire，6 parts of ENR and 6 parts of PP-MAH were used；the compatibility on the boundary between PP and ground tire improved by the addition of two-component compatibilizer from the view of SEM on the impact cross-section. |
