| 对凹凸棒石进行表面改性得到预处理凹凸棒石（PAT），研究PAT/SBR复合材料的加工性能、物理性能及动态力学性能等。结果表明，PAT用量增大，PAT/SBR复合材料的门尼粘度先升后降，t10和t90缩短，邵尔A型硬度、定伸应力和拉伸强度提高，耐磨性能下降，压缩疲劳温升、永久变形和损耗因子tanδ值增大；PAT和预处理白炭黑（PWCB）用量相同时，PAT/SBR复合材料的门尼粘度、压缩疲劳温升和tanδ值小于、静压缩率和初动压缩率大于PWCB/SBR复合材料。 |

| 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. |
