α-氰基丙烯酸酯胶粘剂改性方法研究概况

Overview of the Modification Method forα-Cyanoacrylate Adhesive

α-氰基丙烯酸酯胶粘剂具有单组分、无溶剂、使用方便、粘接广泛、剪切强度高等优点,但其稳定性差、脆性大、耐热温度低、耐水性差、黏度低等缺点在一定程度上限制了胶粘剂的进一步应用。对α-氰基丙烯酸酯胶粘剂各种改性方法进行了概述,并对改性技术进行了展望。

α-cyanoacrylate adhesive has the advantages of one-component,solvent-free,easy to use,wide range of bonding and high shear strength,but its poor stability,brittleness,low heat-resistant temperature,poor water resistance,low viscosity and other shortcomings limit the further application of adhesives to a certain extent.Various modification methods forα-cyanoacrylate adhesives are summarized,and the prospect of modification technology is described.
