An α-cyanoacrylate adhesive composition which comprises an α-cyanoacrylate; a phthalic acid ester represented by the following formula [1]:
wherein R₁ and R₂ are each independently a C₁₋₂₀ alkyl, C₂₋₁₀ alkenyl, C₁₋₁₀ alkoxy-C₁₋₁₀ alkyl or C₃₋₁₀ cycloalkyl group or an aralkyl group in which the alkyl part contains 1 to 5 carbon atoms; and an elastomer, gives greatly improved flexibility and brittleness to the cured adhesive without lowering fast-curing property and bonding strength, and is particularly excellent in maintaining flexibility.
一种α-氰基丙烯酸酯粘合剂组合物,它包括一种α-氰基丙烯酸酯;一种由下式[1]表示的邻苯二甲酸酯:
其中R₁和R₂各自独立地为C₁₋₂₀烷基、C₂₋₁₀烯基、C₁₋₁₀ 烷氧基-C₁₋₁₀ 烷基或C₃₋₁₀ 环烷基或芳烷基,其中烷基部分含有1至5个碳原子;和一种弹性体,在不降低快速固化性能和粘接强度的情况下,大大提高固化粘合剂的柔韧性和脆性,尤其在保持柔韧性方面表现出色。
