Abstract

The invention discloses a manufacturing method of an epoxy-ester resin aqueous dispersion and the anti-corrosion primer on the basis of the epoxy-ester resin aqueous dispersion, characterized in that the aqueous dispersion is a self-drying core-shell structured aqueous dispersion emulsion with the epoxy resin as the core and the reactive non-transfer surfactant as the shell; the anti-corrosion primer has the epoxy-ester resin aqueous dispersion emulsion with acid value of 2 to 10 mg KOH / g, solid content ranging from 40 percent to 60 percent as the basic component. The construction performance, self-drying property and the paint film mechanical strength of the produced waterborne anti-corrosion primer are all comparable to the solvent type epoxy resin coating.

Description

technical field

[0001] The present invention relates to a kind of resin emulsion that can be used to prepare environment-friendly water-based coating and the manufacturing method of the coating based on this emulsion, relate in particular to a kind of epoxy ester resin aqueous dispersion emulsion and based on this emulsion The manufacture method of antirust primer. Background technique

[0002] In order to prevent corrosion of equipment components, in recent years, a series of anti-rust coatings have been developed in China, but most of them are solvent-based anti-rust coatings. This kind of paint contains not only a large amount of organic solvents that can pollute the environment, but also a large amount of toxic pigments, causing serious environmental problems. For this reason, the research and development of new environmentally friendly water-based antirust coatings is in line with the current development trend of the coatings industry.
