| Abstract: |
| A pretreated attapulgite(PAT) was obtained by modifying the surface of attapulgite(AT)，and the processibility，physical properties and dynamic mechanical properties of PAT/SBR composites were investigated.The results showed that the Mooney viscosity of PAT/SBR composites increased at first，and then decreased，t10 andt90 reduced，Shore A hardness，modulus and tensile strength increased，abrasion resistance decreased，and the compression fatigue temperature rising，compression set and tanδ increased with the increase of PAT proportion in the composites；and the Mooney viscosity，compression fatigue temperature rising and tanδ of the PAT/SBR composite were lower than and its static compression ratio and initial dynamic compression ratio were greater than those of the pretreated silica/SBR composite when the same proportion of PAT and pretreated silica was used in the respective composite. |
