This invention discloses a self-curing epoxy resin of triazine derivatives and polyetheramine, its preparation method, and its applications. It relates to the technical field of self-catalytic curing agent synthesis and epoxy resin preparation. The preparation method includes the following steps: adding cyanuric chloride to a solvent, adding an aliphatic amine, reacting, removing the solvent, then adding an alkali and dichloromethane and stirring to react. After the reaction is complete, washing and freeze-drying yield the triazine derivative; mixing the triazine derivative with polyetheramine, then adding epoxy resin, and curing to obtain the self-curing epoxy resin of triazine derivatives and polyetheramine. This preparation method not only significantly reduces the curing temperature but also achieves synergistic enhancement of rigidity and flexibility by adjusting the rigid curing agent of the triazine derivative and the flexible curing agent of the polyetheramine.

This invention provides a method for preparing triazine aromatic amine dimers. The method involves mixing a triazine compound monomer and an inorganic salt, followed by a high-temperature solid-phase reaction to obtain a crude product. The crude product is then washed to remove the inorganic salt, yielding the triazine aromatic amine dimer. The inorganic salt is selected from one or more of lithium bromide, lithium chloride, lithium fluoride, zinc chloride, and zinc sulfate. This method uses the inorganic salt as a "dynamic active interface" to precisely guide the reaction pathway during the high-temperature solid-phase reaction, achieving highly selective synthesis of triazine aromatic amine dimers. It offers advantages such as high product selectivity, a green process, simple operation, and recyclable inorganic salts.
