摘　　要：通过纳米微粒补强橡胶的研究分析和对相关文献的总结,提出已有的补强理论,特别是当前Payne效应,不能解释的问题,针对这些问题,给出了新的纳米微粒补强橡胶的补强机理和Payne效应的解释。纳米微粒补强橡胶的根本原因是由于纳米效应在纳米微粒表面形成了一层玻璃态结构的"结合胶",结合胶内部的结构直接影响应力的传递效率;而Payne效应产生的原因则是由于结合胶收到较大的剪切力发生分子链解纠缠引起的模量快速下降。Through the research and analysis of nano-particle reinforced rubber and the summary of relevant literature,the existing reinforcement theory was studied,especially the current Payne effect can not explain the problems.In order to solve these problems,the new nano-particle reinforced rubber reinforcement mechanism and Payne effect explanation were given.A layer of glass-like"bound rubber"was formed on the surface of nano-particle due to nano-effect,which caused the nano-particle reinforced rubber,and the internal structure of the bonding gel directly affected the stress transfer efficiency.The Payne effect was caused by the yield of adhesive due to the larger shear force it receives.
