摘要
采用石墨及锯末等填料填充沥青的方法制备沥青型粘弹性阻尼材料,研究了沥青型阻尼材料的表观形貌、流动性、玻璃化转变温度、动态力学性能及支架结构的阻尼特性。研究结果表明,以石墨为填料的沥青型阻尼材料减振效果优于以锯末为填料的阻尼材料,当石墨填充量为7.5份时(沥青质量为100份)所制备的阻尼材料综合性能较好。
In this paper,pitch viscoelasticity damping materials were prepared by blending graphite and sawdust in pitches.Some properties of damping materials such as apparent morphology,fluˉidity,Tg,dynamic mechanics properties and damping properties of bracket structure were charˉacterized.The results show that damping materials blending with graphite in pitches has better absorptionshocks effect than those with sawdust.When amount of graphite is selected as7.5wt%(based on amount of pitches),the prepared damping materials has good combined properties.
