Abstract
The high damping and wide-temperature-range CIIR crosslinking composites were prepared successfully with the basic materials CIIR materials through the technology of anti-plasticization interactions. And their damping properties、mechanical properties and microstructure were investigated. The results showed that the CIIR/CP-70/PF composites have only one tanδ peak, which displays the excellent compatibility between the CP-70 and the CIIR matrix. More importantly , the tanδ peaks of the composites shift to the higher temperature with the use of CP-70 in the composites, and the tanδ value of the composites obviously synchronously increases to about 1.38, and the temperature range were improved to above 90℃.At the same time, the mechanical properties of the composites results in considerable tensile strength. The high damping and mechanical properties endow the composites with a potential and promising application future in engineering. SEM and DSC results prove that the majority of AO-2246 dissolve in the CIIR matrix and results illustrate that CP-70 in the matrix exists in anamorphous forms. The results prove that strong anti-plasticization interactions are formed between CP-70 and CIIR matrix.
