Synthesis of modified aqueous epoxy resin and method for preparing antiseptic rusty paint

Abstract

The invention discloses synthesis of modified aqueous epoxy resin and a method for preparing antiseptic rusty paint, relating to synthesis of epoxy resin and a method for preparing paint. The invention solves the problems of the traditional aqueous epoxy resin antiseptic paint that storing stability of base material resin and water resistance and corrosion resistance of an aqueous epoxy resin antiseptic paint coating film can not be met simultaneously. the synthesis method of modified aqueous epoxy resin comprises the steps of: mixing Span 60 with Tween 20, adding E-51; heating and stirring, and dropwise adding distilled water till the system viscosity is suddenly reduced; and finally dropwise adding an initiating agent and a monomer to carry out heating reaction. The method for preparingantiseptic rusty paint comprises the steps of: mixing the modified aqueous epoxy resin, a corrosion inhibitor and a rust preventing agent, stirring and grinding; adding a defoaming agent, a curing agent and deionized water; and stirring the mixture to obtain the modified aqueous epoxy resin antiseptic rusty paint. The invention simultaneously meets the storing stability of the base material resin of the aqueous epoxy resin antiseptic paint and the water resistance and the corrosion resistance of the aqueous epoxy resin antiseptic paint coating film.

Description

technical field

[0001] The invention relates to the synthesis of epoxy resin and the preparation method of the paint. Background technique

[0002] In recent years, with the "green revolution" in the world, it has challenged the material industry and promoted the development of new materials in the direction of high efficiency, energy saving and eco-friendliness. In the field of coatings, water-based coatings have gradually become one of the substitutes for solvent-based coatings since they were researched and developed in the 1970s because of their outstanding advantages such as safety and low VOC (volatile organic compounds). With the development of industry, the application of water-based epoxy resin anti-corrosion coatings is becoming more and more widely. It has been successfully applied in the fields of marine corrosion environment, dipping corrosion environment and non-immersion environment. However, water-based epoxy resin anti-corrosion coatings are developing rapi...
