氰基丙烯酸乙酯的贮存稳定性研究

Study on storage stability of ethyl cyanoacrylate

采用正交设计法分析了对苯二酚、氟硼酸 (HBF4)、甲基磺酸乙酯三种阻聚剂不同配比对氰基丙烯酸乙酯贮存稳定性的影响 ,用DSC法测试并比较了组成不同时该酯的固化反应活化能。性能测试结果表明 ,加入稳定剂优化后的氰基丙烯酸乙酯具有较高的粘结强度和良好的贮存稳定性。

In this paper, the effect of stabilizers addition to ethyl cyanoacrylate on its storage stability is discussed by the method of orthogonalization, including hydroquinone, fluoboric acid and ethyl methylsulfonate. By the use of DSC, the activation energy of curing reaction is compared in two cyanoacrylates, whose compositions are different. In the end, the properties of the optimized cyanoacrylate are determined, and the result suggests that is has high bonding strength and good storage stability.
