摘要

Damping materials are widely used in the modern industry as a kind of material for reducing vibration. The high-damping composites consisting of chlorinated polyethylene (CPE) and 4,4 '-Methylenebis(2,6-di-t-butylphenol) (AO-4426) were successfully prepared in this work. The microstructural and mechanical properties of the CPE/AO-4426 composites were systematically investigated by using SEM, DSC, FTIR, and DMA. From the SEM, most of hindered phenol was dissolved in the CPE matrix and formed a fine dispersion. The results of DSC and FTIR suggested that strong intermolecular interaction like the hydrogen bonding was formed between the AO-4426 and CPE. It was found that with the increase of AO-4426 content, a new transition appeared above the glass transition temperature of the CPE matrix, with higher glass transition temperature and higher tan delta value than the neat CPE. As expected, the hybrid displayed excellent performance and had exciting potential applications as a damping material. (c) 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 48321.
