酚醛树脂种类及用量对天然橡胶/溴化丁基橡胶高阻尼胶料性能影响

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 phenolic resin types and addition levels on the properties of NR/BIIR high damping rubber compound was investigated.The results showed that comparing 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.With the addition level of thermosetting phenolic resin HY-2045 increased，the effective damping temperature range tended to widen，while the damping capacity in high temperature range（＞0 ℃） decreased
