Application of alkyd resin esterification waste water in preparation of alkyd resin paint

The invention provides an application of alkyd resin esterification waste water in preparation of alkyd resin paint. According to the application, water-soluble compounds which are high in treatment difficulty and pollute the environment in the alkyd resin esterification waste water are converted into a film forming material for oxidation drying of low-VOC alkyd resin paint, so that the water-soluble compounds are prevented from being released to air and polluting the environment, and considerable economic and social benefit is generated. Prepared emulsifying water used for the alkyd resin paint participates oxidation crosslinking of the paint and covers the waste water by cooperation with a dispersing agent, pigment and a filler so as to form water-in-oil pigment filler pulp, and therefore a produced product is low in cost and good in performance and has low viscosity, freezing resistance, and other special effects.
