Abstract

The invention discloses a preparation method for an anticorrosion resin emulsion paint. The preparation method comprises the following steps: adding a polyester resin and an epoxy resin into a reaction vessel, then adding an antirust pigment, a coloring pigment and a filling material, carrying out mixing for 0.5 to 1 h with stirring, adding an auxiliary agent and a mixed solvent after uniform dispersion and then carrying out grinding, filtering, barreling and packaging so as to prepare a component A; adding tricarboxymethyl propane, a polyurethane dehydrating agent and cyclohexanone into the reaction vessel together, starting stirring, then stopping stirring when a temperature rises to 80 DEG C through heating, continuing heating to a temperature of 140 DEG C, allowing a mixture of the dehydrating agent and water to be evaporated, adding a plasticizer and toluene diisocyanate into the reaction vessel and allowing a reaction temperature to be maintained at 40 to 50 DEG C so as to prepare a component B in 2 h; and blending 60 to 80% of the component A and 20 to 40% of the component B so as to obtain a finished paint. The anticorrosion paint provided by the invention has stable quality; through usage of the polyester resin and the epoxy resin as base materials and formation of an interpenetrating polymer network, a coating is endowed with compactness, and anticorrosion performance and adhesion of the coating are substantially improved.

Description

technical field [0001] The invention relates to a coating, in particular to a preparation method of an anti-corrosion resin coating. Background technique [0002] Anti-corrosion coatings, generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, are an indispensable coating in paint coatings. Conventional anti-corrosion coatings play an anti-corrosion effect on metals under normal conditions and protect the service life of non-ferrous metals; A type of anti-corrosion coating that achieves a longer protection period than conventional anti-corrosion coatings. [0003] The existing coatings have poor corrosion resistance and adhesion stability, and are prone to blistering, rusting, fading and falling off. Contents of the invention [0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a method for preparing a non-foaming, non-rusting, non-fading, non-shedding anti-co...
