增塑剂种类对耐寒减震胶料性能的影响

研究增塑剂种类对耐寒减震胶料性能的影响。结果表明：增塑剂种类对胶料硫化特性的影响在可控制范围内；各增塑剂胶料的物理性能均满足建筑减震橡胶制品相关标准要求；在－20～40 ℃温度区间，各增塑剂胶料的损耗因子波动很小，增塑剂DBP胶料在低温下的等效阻尼比和剪切储能模量保持率最大，更适用于耐寒减震橡胶制品。;The effects of plasticizer types on the properties of cold-resistant and damping compounds were investigated.The results showed that the effects of plasticizer types on vulcanization characteristics of the compounds were within the control range.The physical properties of the compounds with different plasticizers met the requirements of relevant standards for building anti-seismic rubber compounds.In －20～40 ℃ temperature range，the loss factors of the compounds with different plasticizers were fluctuated lightly.The retention ratio of equivalent damping ratio and shear storage modulus of the compounds with plasticizer DBP at low temperature were largest，so it was more suitable for the cold-resistant and damping compounds
