摘　　要：研究酚醛树脂种类及用量对天然橡胶(NR)/溴化丁基橡胶(BIIR)高阻尼胶料性能的影响。结果表明:与采用热塑性烷基酚醛树脂203的胶料相比,采用热反应性辛基酚醛树脂HY-2045的胶料的硫化速率较快,邵尔A型硬度和拉伸强度较高,拉断伸长率略低,有效阻尼温域较宽;随着热反应性辛基酚醛树脂HY-2045用量的增大,胶料的有效阻尼温域呈现变宽的趋势,但高温区域(>0℃)的阻尼性能呈现下降的趋势。The effect of the type and additive level of phenolic resin on the properties of high damping NR/BIIR compound was investigated.The results showed that compared with those of the rubber compound with thermoplastic phenolic resin 203,the curing rate of the rubber compound with thermosetting phenolic resin HY-2045 was faster,the shore A hardness and tensile strength were higher,the elongation at break was slightly lower,and the effective damping temperature range was wider.When the addition level of HY-2045 increased,the effective damping temperature range was broadened,while the damping in the high temperature range(>0℃)decreased.
