摘　　要：阐述了纳米填料 /橡胶体系在贮存停放过程中 ,填料与橡胶之间及填料与填料之间相互作用的变化。结果表明 ,纳米填料 /橡胶体系在贮存停放过程中结合胶的形成是动力学平衡过程 ,随着停放时间的延长 ,填料与橡胶之间的相互作用增强 ,填料与橡胶之间的相互作用活性点面积减小 ,同时填料与填料之间的相互作用增强 ,填料网络结构絮凝程度提高。制备纳米填料 /橡胶复合材料时 ,应促进混合体系在贮存停放过程中填料与橡胶之间的物理浸润和化学结合作用 ,阻止因填料与填料之间相互作用而产生的絮凝现象 。The changes of interactions of filler-rubber and filler-filler of nanofiller/rubber system during storage period were reviewed with 38 references.The results showed that the formation of bound rubber in the nanofiller/rubber system during storage period was a dynamic equilibrium process.The filler-rubber interaction was improved and the interaction site area decreased as the increase of the storage time.Simultaneously,the inter-action of filler-filler was enhanced and the flocculation of the filler network was improved.Therefore, the physical infiltration and chemical combination of filler-rubber were improved,and the flocculation resulted from the interaction of filler-filler was prevented in nanofiller/rubber system during storage period.The nanofillers could play a role of reinforcement in rubber matrix by the nano-dispersion and the strong interfacial phase.
