摘　　要：以杜仲胶(EUG)为基体,偶氮二甲酰胺(AC)为发泡剂,采用硫磺硫化体系制备具有泡孔结构的EUG硫化胶,分析了硫化剂、发泡剂、增塑剂等用量对泡孔形态和发泡硫化胶性能的影响。结果表明,发泡硫化胶内的泡孔呈现开孔状态,其直径主要在200~350μm之间;通过调整加工助剂用量,可得到最优阻尼性能的发泡硫化胶,其最小密度为0.534 g/cm 3,邵尔A硬度为53,孔隙率为45.4%,损耗因子为0.32。Eucommia ulmoides vulcanized gums with bubble structures were prepared by sulfur vulcanization system using eucommia ulmoides gum(EUG)as matrix and azodicarbonamide(AC)as foaming agent.The effects of the dosage of vulcanizing agent,foaming agent and plasticizer on the shape of bubble hole and the properties of foaming vulcanizing adhesive were analyzed.The results show that the pores in the foamed vulcanizate are open,and the diameter is mainly between 200 and 350μm.By adjusting the amount of processing additives,the best damping performance of ulmoides vulcanized foam gum can be obtained.Moreover,the density,shore hardness,porosity and tanδof ulmoides vulcanized foam gum are 0.534 g/cm 3,53,45.4%,0.32,respectively.
