摘要l本文通过石油树脂同氯化丁基橡胶共混,制备了一系列性能优良、价格低廉的新型阻尼材料。本研究着重考察了石油树脂软化点及添加量对阻尼材料性能的影响。材料的DMA结果表明,氯化丁基橡胶和石油树脂的共混物是相容体系, tan占峰随石油树脂软化点温度的提高而依次向高温方向偏移;另一方面,随石油树脂含量的增加,材料的tan 6峰依次向高温方向偏移,并且tan 8峰值也随之提高。, 关键词氯化丁基橡胶阻尼石油树脂
Abstract The effects of petroleum resins on the damping pmper[ies of chlorinated bull rubber(C1一 IR)were investigated by dynamic mechanical analysis As to the binary systems of CIIR/petroleum show a single tan 8 peak associated with CIIR,and its peak location shifts to higher tem peratures with increasing the softening points of the petroleum resins,this behavior shows that petmle— am resins patible with the other hand,in case of the effect of petroleum resin content on the damping w∞found that with increasing the P'/0 maximum value of
the tan 8 peak also increase and its peak location shifts to higher CIIR/petroleum res-
ins system is a high-performauce damping material.

随着人们对生活环境舒适性要求的提高以及军工产业的需求,阻尼材料的研发受到很多研究人员的关注。制备高分子阻尼材料的方法主要有共混、IPNsⅢ和高分子与有机小分子杂化Ⅲ技术。共混法仅仅局限于高聚物与高聚物之间的共混,而高聚物与低聚物共混制备阻尼材料的方法鲜有报道
