Abstract

According to the technical scheme, the waterborne epoxy curing agent comprises main materials and auxiliary materials, the main materials comprise vinyltriamine, polyethylene polyamine, diethylaminopropylamine and trimethyl hexamethylene diamine, and the auxiliary materials comprise antimonous oxide, melamine and polyurethane. The main materials comprise the following components in parts by mass:30-60 parts of vinyltriamine, 30-60 parts of polyethylene polyamine, 30-60 parts of diethylaminopropylamine and 50-80 parts of trimethylhexamethylene diamine. The waterborne epoxy curing agent for theengineering machinery anticorrosive paint has the beneficial effects that: by arranging the main material consisting of the vinyltriamine, the polyethylene polyamine, the diethylaminopropylamine andthe trimethylhexamethylene diamine and the auxiliary material consisting of the antimonous oxide, the melamine and the polyurethane, the finally prepared waterborne epoxy curing agent has relatively good color stability, and meanwhile, has relatively good bonding performance and chemical corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of curing agents, in particular to a water-based epoxy curing agent for construction machinery anticorrosion coatings. Background technique [0002] Curing agent, also known as hardening agent, curing agent or stabilizer, is a kind of substance or mixture that promotes or controls the curing reaction. Resin curing is through chemical reactions such as condensation, ring closure, addition or catalysis, so that the thermosetting resin undergoes an irreversible change process, and curing is completed by adding a curing (crosslinking) agent. Curing agent is an essential additive, whether it is used as adhesives, coatings, or castables, it is necessary to add a curing agent, otherwise the epoxy resin cannot be cured. The variety of curing agent has a great influence on the mechanical properties, heat resistance, water resistance and corrosion resistance of the cured product; [0003] The resin in the form of wa...
