An epoxy monolith layer with porous structure is fabricated on the surface of a stainless steel (SUS) plate by polymerization induced phase separation process as the mediator for the bonding of SUS and various thermoplastic resin plates. Bonding strength is evaluated in the presence and absence of the epoxy monolith layer by a tensile lap shear test. The morphology of fracture surfaces is observed by scanning electron microscopy (SEM) in order to clarify the anchor effect of molten resins into the pores of the epoxy monoliths. The bonding strength values are calculated to be 1.2‒2.7 MPa based on an apparent adhesion area for the bonding of SUS with polyethylene, polypropylene, polyoxymethylene and acrylonitrile–butadiene–styrene copolymer in the presence of the epoxy monolith mediator. These values are 2‒30 times higher than those for direct metal-resin bonding. By the SEM observation, stretched needle-like structures were detected on the both fracture surfaces of the resins and the epoxy monoliths. The direct observation of the stretched debris out of the holes located at the monolith surfaces indicates the significant anchor effect for the present metal-resin bonding system. The bonding system mediated by the epoxy monolith layer is conveniently used for the bonding of dissimilar materials such as metals and resins without any special process and apparatus.

环氧树脂整体层介导的金属-树脂键合

通过聚合诱导相分离工艺在不锈钢(SUS)板的表面上制造具有多孔结构的环氧整体料层,作为SUS和各种热塑性树脂板粘结的介质。通过拉伸搭接剪切试验在存在和不存在环氧整料层的情况下评估粘合强度。通过扫描电子显微镜(SEM)观察断裂表面的形态,以阐明熔融树脂在环氧整体料的孔中的锚固效应。根据表观粘合面积,将SUS与聚乙烯,聚丙烯,聚甲醛和丙烯腈-丁二烯-苯乙烯共聚物粘合时的表观粘合面积,计算得出的粘合强度值为1.2‒2.7 MPa。这些值比直接金属树脂键合的值高2到30倍。通过SEM观察,在树脂和环氧整料的两个断裂表面上检测到拉伸的针状结构。从位于整料表面处的孔中直接观察到的碎片被拉伸,表明对于本发明的金属-树脂粘结系统而言,锚固效果显着。由环氧整体料层介导的粘结体系可方便地用于粘结不同的材料,例如金属和树脂,而无需任何特殊的工艺和设备。从位于整料表面处的孔中直接观察到的碎片被拉伸,表明对于本发明的金属-树脂粘结系统而言,锚固效果显着。由环氧整体料层介导的粘结体系可方便地用于粘结不同的材料,例如金属和树脂,而无需任何特殊的工艺和设备。从位于整料表面处的孔中直接观察到的碎片被拉伸,表明对于本发明的金属-树脂粘结系统而言,锚固效果显着。由环氧整体料层介导的粘结体系可方便地用于粘结不同的材料,例如金属和树脂,而无需任何特殊的工艺和设备。
