主　　题：Carbon black Natural rubber Carbon black coupling agent Anti-reversion properties 

摘      要：Natural rubber(NR)is not only the main compounding ingredient used to make the majority of components of tires as well as other rubber products,as it plays a significant role in ensuring that they operate well and complies with environmental *** applications of NR products are lim-ited to high temperatures due to the revision tendency of NR *** address these issues,the potential engagement of a carbon black(CB)coupling agent(CA)in the presence of metal oxide *** Oxide(ZnO)was investigated in an NR-based *** CA has dual functionality on physicomechanical *** has the ability to reduce hysteresis loss as well as improve anti-reversion properties and these properties thorough-ly depend on the presence of *** ZnO was added to the master formulation,a 65%improvement in reversion properties was *** the other hand,while ZnO fully transferred to the final formulation,bound rubber(BR)content increased by 19%,the difference in storage modulus(ΔG’)is reduced by 22%,cure rate index(CRI)improved by 14%,loss tangent(tanδ)reduced by 18%and slightly improve in elongation at break compared to control ***-gravimetric analysis(TGA)was engaged to understand the thermal stability and degree of purity of CA.A differential Scanning Calorimeter(DSC)was used to detect the phase tran-sition of *** Transform Infrared Spectrum(FTIR)was adopted to detect the presence of carboxyl and amine groups in the CA *** effect,BR content and Transmission Electron Microscope(TEM)were em-ployed to investigate the micro-level dispersion of CB in the natural rubber(NR)matrix.
