摘　　要：通过机械划痕、酸洗和磷化三种表面处理的方法对钢板进行物理和化学处理,研究了不同处理方法对钢板与环氧树脂粘结强度的影响。利用表面粗糙度轮廓仪、光学显微镜和SEM扫描电镜对钢板表面形貌和环氧树脂的涂覆效果进行研究。结果表明:钢板表面腐蚀坑的形状、分布、粗糙度是影响其与环氧树脂粘结强度的主要因素。通过比较,酸洗处理25 min的试样粘结强度提高最大,较未处理的样品提高了169%。The technology and methods of mechanical and chemical pretreatments were studied,include mechanical scratches、grinding with emery paper、acid etching and phosphating. Their influences on the bonding strength of steel and epoxy resin were studied as well. The effect of the epoxy coating was studied by profilometer,optical microscope and scanning electron microscope（ SEM）. The results show that the shape of the groove,distribution,surface roughness of the samples are the major factors affecting the bonding strength of steel and epoxy. These treatments and methods greatly improve the bonding strength between epoxy and steel. Finally,the bonding strength of a sample pickled for 25 mins is improved most,which increase by 169% compared with the untreated sample.
