Abstract

Benzophenone imine (BPI), a simple imine compound and common chemical material, is used to enhance the overall performance of natural rubber (NR)/carbon black (CB) nanocomposites. The influence on the strain softening behavior of NR/CB nanocomposites is investigated. The incorporation of BPI regulates the crosslinking network structure of NR matrix, accelerates the vulcanization and significantly increases the crosslinking density. Furthermore, BPI can facilitate the dispersion of CB and improve the interfacial interaction between CB and NR. Consequently, it can improve the mechanical properties, mitigate the damping and softening percentages of highly-filled nanocomposites and further reduce their hysteresis loss and heat generation. These findings may offer some valuable insights into the design and optimization of high-performance NR/CB nanocomposites for industrial applications.

二苯甲酮亚胺对天然橡胶/炭黑纳米复合材料应变软化行为的影响

二苯甲酮亚胺（BPI）是一种简单的亚胺化合物，是一种常用的化学材料，用于提高天然橡胶(NR)/炭黑（CB）纳米复合材料的综合性能。研究了对NR/CB纳米复合材料应变软化行为的影响。BPI的加入调节了NR基体的交联网络结构，加速了硫化，显著提高了交联密度。此外，BPI能促进炭黑的分散，改善炭黑与NR的界面相互作用，从而改善高填充纳米复合材料的力学性能，降低其阻尼和软化百分比，进一步降低其滞后损失和热量产生。这些发现可能为工业应用的高性能NR/CB纳米复合材料的设计和优化提供一些有价值的见解。
