中文摘要:
      通过对3种不同结构SBR硫化胶磨耗前后的红外光谱图和磨耗表面扫描电镜照片进行分析，研究了SBR硫化胶的磨耗性能、形态及磨耗过程中微观结构的变化。结果表明，磨耗过程是机械力引发具有活化的链式氧化反应的力化学反应，磨耗过程中分子主链和单硫键断裂程度越大，生成醚键数量越多，SBR硫化胶的耐磨性越差，其磨耗表面的磨纹越粗。
英文摘要:
      The abrasion properties，morphology and microstructure of SBR vulcanizates with three different structures were studied by analysing their infra-red spectras before and after abrasion, and their SEM cross-section pictures.The results showed that the abrasion process was a mechano-chemical reaction including active chain-oxydized reaction initiated by the mechanical force；the more the main chains and monosulfide bonds in the molecule broke in the abrasion process,the more the quantity of ether bonds produced,the poorer the abrasion properties and the rougher the abrasion surface.
