Investigation of preparation for reactive halloysite loading ZDMA and its thermo-oxidative resistance on the HNBR/FKM composites
Improvement of thermo-oxidative resistance of rubber composite has not been solved well so far, it has always been a focus of research and attracts the great interest of scientists. In this work, a novel reactive halloysite nanotubes (RHNTs) loading zinc methacrylate (ZDMA) as chemical antioxidant were prepared via in situ preparation of zinc methacrylate (ZDMA) in the lumen of halloysite nanotubes (HNTs). The presence of ZDMA in the lumen of halloysite nanotubes was characterized and confirmed by FTIR, TEM, and TGA. The effect of RHNTs on the mechanical properties and thermo-oxidative resistance for HNBR/FKM-blended rubber composites was investigated, respectively. Especially, the RHNTs modified by silane coupling agent exhibited the best dispersibility in HNBR/FKM polymer matrix, and the tensile strength of HNBR/FKM/m1-RHNTs composites was much higher than that of blank sample. During thermo-oxidative aging at 150 ℃, all the HNBR/FKM/RHNTs composites did not exhibit extreme value phenomenon of tensile strength due to aging reinforcement within the first 72-h period. The data of DSC curves showed that the HNBR/FKM/m1-RHNTs exhibited the minimum ΔTg among all the samples. Based on the above results, obviously, it was verified that RHNTs showed better reinforcement and thermal oxygen aging resistance effect.
期刊介绍：
"Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad.
"Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
