Palmitic acid butyl ester be sequentially added into emulsifying kettle stirring and dissolving be transparency liquid continuously add 18-20 part deionized water stand after in point
The water-in-oil emulsion of layer, agitated dispersion forms steady pre-emulsion；
(2) dissolve after potassium peroxydisulfate being dissolved in 1 part of deionized water stirring and make initiator；
(3) in reactor, add 20-30 part deionized water, and be heated to the pre-breast of dropping 5%-10% when 75-90 DEG C
Liquid, continues the initiator of dropping 10% after question response temperature in the kettle is stable；
(4) to (3) dropping residue pre-emulsion and initiator, after being incubated 1 hour, it is cooled to less than 50 DEG C, and is sequentially added into and disappears
Infusion, preservative, triethanolamine, filter and i.e. obtain water-borne acrylic resin.
Further, the preparation method of a kind of acrylic polyurethane enamel water-borne acrylic resin, it is by weight
Following components composition:: ethyl acrylate 25 parts, benzene second 12 parts, butyl acrylate 8 parts, methyl methacrylate 4 parts, methyl
5 parts of acrylic acid, N hydroxymethyl acrylamide 8 parts, N-[2-(2-methyl-4-oxopentyl) 0.5 part, triethanolamine 1 part, potassium peroxydisulfate 0.2 part,
