铁锚101胶在粘接结构中的老化机理

Aging Mechenism of Anchor 101 Adhesive in Bonding Structures

  • 摘要: 以铁锚101胶为粘接剂,工业三乙醇胺为固化剂,制备了橡胶-玻璃纤维粘接结构。同一温度下对粘接结构进行加速老化试验,测定不同老化时间后粘接结构中胶黏剂的180°剥离强度,对粘接结构的剥离界面进行宏、微观观察,并通过红外(IR)、示差扫描量热(DSC)等对胶黏剂进行表征,研究粘接结构中胶黏剂的微观形貌、失效模式和活性官能团结构随老化时间的变化。

     

    Abstract: Rubber-glass fiber bonding structure is prepared by using anchor 101 as adhesives and industrial triethanolamine as curing agents.The 180°peeling strength of adhesives after different aging times at the same temperature were determined,and the micro-morphology,failure mode and active functional group structure changes were studied by macro observation,SEM,IR and DSC.
