选用胎面胶混炼胶和胎肩垫胶混炼胶,采用模压硫化方式制备了单胶试样以及具有不同粘合界面的试样,通过考察热空气老化时间对试样拉伸性能及疲劳寿命的影响,探讨了胶/胶界面状态与拉伸性能及耐疲劳性能之间的关系。结果表明,在受外力作用时,胶/胶界面能够传递应力,并以界面脱粘和滑动摩擦等方式吸收外力破坏能,阻断裂纹扩展,提高粘合强度和动态疲劳强度;粘合胶界面对改善试样的动静态强度更加有效。
The selection of the tread rubber and the rubber tire shoulder pad rubber, the use of molded vulcanization prepared a single sample and a sample with different bonding interface, by examining the hot air aging time on the tensile properties of the sample and fatigue Life of the impact of the glue / plastic interface state and tensile properties and fatigue resistance between the relationship. The results show that when subjected to external force, the interface of glue / glue can transfer stress, and absorb the damage energy of external force through interfacial debonding and sliding friction to block the crack growth and improve the bonding strength and dynamic fatigue strength; To improve the static and dynamic strength of the sample more effective.
