摘要
动态生热是橡胶黏弹性的直接体现,是外加机械能向热能的转化。动态生热产生的热量积累直接影响材料的使用性能,生热导致的温度上升会降低橡胶复合材料的力学强度、静态和动态模量以及耐磨性等。为此,开展了橡胶复合材料动态生热机理及低生热调控方面的研究。本文从橡胶基体网络结构、强化粒子分散、加工工艺和理论模拟等角度出发,对橡胶低生热研究进行了归纳、总结及展望。
Dynamic heat generation is the direct embodiment of rubber viscoelasticity,which is the transformation from external mechanical energy to thermal energy.The accumulation of heat generated by dynamic heat generation directly affects the performance of materials,as a result,the temperature rise reduces the mechanical strength,static and dynamic modulus and wear resistance of rubber composites.Therefore,research on dynamic heat generation mechanism and low heat generation regulation of rubber composites have been carried out.In this paper,from the perspectives of rubber matrix network structure,enhancing particle dispersion,processing technology and theoretical simulation,the research on low dynamic heat generation of rubber is summarized and analyzed,and the prospect is put forward.
