Embodiment 1-4

[0031] The fluorine-modified styrene-acrylic coatings of Examples 1-4 were prepared according to the following steps.

[0032] (1) Under the stirring condition of 1000 rpm, add emulsifier, leveling agent, drier, dispersant, defoamer, stabilizer to the water, stir for 20-30 minutes and then reduce the stirring speed to obtain a slurry, spare;

[0033] (2) Add fluorine-modified styrene-acrylic emulsion to the slurry obtained in step (1) successively under the stirring condition of 1000 rpm, film-forming resin, cyclodextrin, sodium bicarbonate, hydroxyethyl cellulose, and pH adjustment agent to adjust the pH value to 8-9 to obtain a slurry;

[0034] The fluorine-modified styrene-acrylic emulsion is obtained by emulsion copolymerization of styrene, acrylate and perfluorooctyl ethyl acrylate in a weight ratio of (1-3):(2-5):(0.5-2);

[0035] (3) Add diatomaceous earth, talcum powder, and heavy calcium carbonate to the slurry obtained in step (2) under stirring conditions of 500 r...

Abstract

The invention relates to an environmental-friendly fluorine-modified styrene-acrylic emulsion coating used in winter and a preparation method of the styrene-acrylic emulsion coating. The coating contains fluorine-modified styrene-acrylic emulsion, film-forming resins, cyclodextrin, sodium bicarbonate, hydroxyethyl cellulose, diatomite, talcum powder, ground limestone, an emulsifier, a flatting agent, a drier, a dispersing agent, an antifoaming agent, a stabilizer and water. The coating has the lowest film forming temperature, is high in stability, and is applicable to use in winter construction.

Description

technical field [0001] The invention relates to the technical field of coatings and preparation, in particular to an environment-friendly fluorine-modified styrene-acrylic emulsion coating used in winter and a preparation method thereof. Background technique [0002] Styrene-acrylic emulsion (styrene-acrylate emulsion) is obtained by emulsion copolymerization of styrene and acrylate monomers. After decades of development in my country, it has excellent adhesion, oxidation resistance and oil resistance. It has been widely used in construction, coatings and adhesives and other fields. However, its water resistance and weather resistance are poor, and it is easy to deform, which limits its application. [0003] At present, silicone or organic fluorine is used to modify styrene-acrylic emulsion. Organosilicon has excellent properties such as high and low temperature resistance, ultraviolet and infrared radiation resistance, and oxidative degradation resistance. Modification of ...
