The invention belongs to the technical field of epoxy resin curing agents, and provides a double-bond-containing phenolic aldehyde amine curing agent and a synthesis method and dual curing application thereof.The preparation method comprises the following steps that aldehyde monomers are added into phenolic monomers and polyamine monomers containing unsaturated side chains in batches or dropwise, and under certain reaction conditions, the double-bond-containing phenolic aldehyde amine curing agent is obtained. And preparing to obtain the double-bond-containing phenolic aldehyde amine. The dual-curing phenolic aldehyde amine provided by the invention is used as an epoxy curing agent and has relatively high Tg and mechanical properties; after a photoinitiator is introduced, ultraviolet light-heat dual curing is performed, and the performance can be further improved. 本发明属于环氧树脂固化剂技术领域，本发明提供了一种含双键酚醛胺固化剂及其合成方法与双重固化应用，制备方法包含如下步骤：在含不饱和侧链的酚类单体和多胺类单体中，分批次或滴加醛类单体，在一定反应条件下，制备得到含双键酚醛胺。本发明提供可双重固化的酚醛胺作为环氧固化剂具有较高的Tg、力学性能；在光引
