METHOD FOR PREPARING ECO-FRIENDLY AQUEOUS AMINE-BASED CURING AGENT, ECO-FRIENDLY AQUEOUS AMINE-BASED CURING AGENT PREPARED THEREBY, AND METHOD FOR FORMING COATING FILM USING ECO-FRIENDLY AQUEOUS AMINE-BASED CURING AGENT

摘要

The present invention relates to a method for preparing an eco-friendly aqueous amine-based curing agent, an eco-friendly aqueous amine-based curing agent prepared thereby, and a method for forming a coating film using the eco-friendly aqueous amine-based curing agent. The aqueous amine-based curing agent according to the present invention can effectively reduce the peculiar odor of amines, has excellent compatibility in a reaction with a main material composed of an epoxy resin, can keep the compatibility intact and the curing properties intact even after the addition of a large amount of water, can also keep the mixability with the main material intact, and thus is very convenient for application in the field due to excellent usability and workability. In addition, the aqueous amine-based curing agent can be used through the post-addition of water as needed on the spot and, even such a case, can keep the curing properties intact, and thus can maximize the utilization of a product. In addition, regardless of the post-addition of water and the addition of a curing accelerator, the balance is not broken, and thus precipitates are not formed and curing properties can be exerted smoothly. In addition, even when the thickness of a coating film is increased, the force between the main material and the curing agent is activated to induce a smooth cross-linkage reaction, thereby keeping high properties of the coating film.
