以α-氰基丙烯酸酯類瞬干膠為膠粘劑, 采用剪切試驗、接觸角試驗和掃描電鏡觀察系統研究了丙酮簡單清洗、噴砂處理、陽極氧化處理以及偶聯劑處理對5083鋁合金板膠接接頭剪切強度的影響。結果表明:經簡單清洗后, 所得膠接接頭的剪切強度最低; 在附著力和機械嚙合的共同作用下, 噴砂處理和陽極氧化處理膠接接頭的強度得到了提高, 其中陽極氧化處理的效果最為明顯, 與簡單清洗膠接接頭相比,剪切強度提高了223.1%; 膠接前適當使用偶聯劑可以使簡單清洗和噴砂處理膠接接頭的剪切強度提高, 在該試驗條件下, KH-550偶聯劑體積分數為5%時, 膠接接頭的剪切強度均達到了最大值; 但偶聯劑使陽極氧化處理形成的納米小孔不能發揮機械嚙合作用,所得膠接接頭的剪切強度相比未使用偶聯劑的反而降低。
Using α-cyanoacrylate as adhesive, the effect of surface treatments such as simple cleaning, sand blasting, anodic oxidation and coupling agent treatment on adhesion strength of 5083 aluminium alloy plates was studied by shearing test, contact angle test and SEM observation. The results indicate that through simple cleaning, the shear strength of the adhesive joints was the lowest. With the combined function of adhesive force and mechanical meshing, the shear strength of the adhesive joints which pretreated by sand blasting and anodic oxidation was increased, the effect of anodic oxidation treatment was the most obvious, and the shear strength of joints pretreated by anodic oxidation increased 223.1% than that of joints pretreated by simple cleaning. Proper using of coupling agent before adhesion resulted in the improvement of shear strength of joints pretreated by simple cleaning and sand blasting. Under this test condition, the proper volume fraction of KH-550 coupling agent was 5%, and bonding with which the shear strength of the joints got to the highest values. However, the shear strength of joints pretreated by anodic oxidation was decreased, because the coupling agent made the mechanical meshing effect of the nano holes formed during anodic oxidation process ineffective.
