摘　　要：丁基橡胶(IIR)因分子链上具有较多的甲基,其阻尼性能优异,但IIR分子链中双键少、不含极性基团,导致IIR与填料的相容性差,且其阻尼复合材料的硫化时间长、与金属等其他材料的粘合性能较差,限制了IIR的进一步应用。本文介绍IIR的共混改性(与无机填料共混改性、与树脂或/和其他胶种共混改性)、与有机小分子杂化改性、结构改性和化学改性制备IIR阻尼复合材料的研究概况,采用这些改性方法制备的IIR阻尼复合材料的阻尼性能提高,阻尼温域拓宽。Butyl rubber(IIR)had excellent damping performance due to the high number of methyl groups on its molecular chain.However,the IIR molecular chain had few double bonds and no polar groups,resulting poor compatibility between IIR with fillers,and IIR damping composites had long vulcanization time and poor adhesion performance with other materials such as metals,which limited the further application of IIR.This article provided an overview of various modification approaches for preparing IIR damping composites,including blending modification of IIR(blending modification with inorganic fillers,blending modification with resins or/and other types of rubber),hybridization modification with organic small molecules,structural modification and chemical modification.The damping performance of IIR damping composites prepared by these modification methods was improved,and the damping temperature range was expanded.
