The invention discloses a single-component water-based
silicon-
fluorine modified
acrylate emulsion wood
lacquer and a preparation method thereof. The preparation method comprises the following steps: S1, weighing a certain amount of water, an emulsifier,
butyl acrylate,
methyl methacrylate,
acrylonitrile,
styrene,
acrylic acid and hydroxyethyl methylacrylate; S2, mixing the raw materials to obtain a pre-
emulsion A; S3, mixing a part of the pre-
emulsion A, vinyl triisopropoxy
silane and a
silicon-
fluorine modified resin to obtain an organic
silicon-
fluorine pre-emulsion B; S4, mixing water, part of the pre-emulsion A,
ammonium persulfate and
sodium bicarbonate to obtain a solution, heating the solution to 80-85 DEG C, and stirring until the solution presents
blue light; S5, adding an
ammonium persulfate aqueous solution and the pre-emulsion A, adding the organic silicon-fluorine pre-emulsion B after the pre-emulsion A is added, then heating to 85-90 DEG C, keeping the temperature for 2-3 hours, then cooling to 65-70 DEG C, adding tert-butyl hydroperoxide and
sodium erythorbate, and keeping the temperature for 0.5-1 hour; and S6, cooling to
room temperature, adding a
preservative and a defoaming agent, and then adjusting the pH value to 7-8 to obtain a finished product.
