α-氰基丙烯酸酯合成及改性工艺的研究

Study on Synthesis Technique and Modification of α-Cyanoacrylate

针对α-氰基丙烯酸酯粘合剂存在的一些缺陷，从合成原理、合成原料、合成工艺、改性方法等方面进行了探讨，确定了以1，3-二氯丙烷为脱水剂dehydrant、在pH值为8—10、反应温度为59．61℃的合成工艺条件，同时也讨论了丙烯腈-丁二烯橡胶（NBR橡胶）、聚甲基丙烯酸异丁酯（PIB-MA）等作为改性剂对其粘度和强度的影响。

The synthesis principle, material, modification etc. were discussed in this paper about α- cyanoacrylate adhesive. The best synthesis techique to get the more output is 1,3 - Dichloropropane as dehydrant, pH around 8 - 10, temperature around 59 -61℃, and influences of NBR, PIBMA on viscosity and strength were discussed.
