摘要

以氯化丁基橡胶为基体材料,通过反增塑作用技术,成功制备出高阻尼宽温域氯化丁基橡胶复合材料,并研究其阻尼性能、力学性能及微观结构。结果表明:复合材料CIIR/CP-70/PF体系的损耗因子-温度(tanδ-T)曲线仅一个单峰,属热力学相容体系,与纯CIIR基体橡胶相比,复合材料的tanδ峰明显向高温移动,且最大损耗因子值及对应温度均大幅度提高,且峰值增加到1.38左右,有效阻尼温域范围90℃以上。同时,CP-70与PF的加入可兼具提高CIIR基体材料力学性能,具有很好的实用价值。SEM及DSC分析结果证明,CP-70以无定形状态分散在CIIR基体中,且CP-70与基体CIIR间存在反增塑作用。

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.
