Embodiment 1

[0043] Preparation of emulsion polymer A of methacrylic acid, 2-hydroxyethyl acrylate, methyl methacrylate and 2-ethylhexyl acrylate by using phosphate ester surfactants:

[0044] By mixing 224g of water, 0.8g of ammonium carbonate, 1.07g of ammonium lauryl sulfate (Sipon TM L-22), 6.4g nonylphenol ethoxylate phosphate (Dextrol TM OC-110), 24 g methacrylic acid, 15.2 g 2-hydroxyethyl acrylate, 488 g methyl methacrylate, and 272.8 g 2-ethylhexyl acrylate to prepare a monomer premix. Initiator A was prepared by dissolving 0.8 g of ammonium persulfate in 8 g of water. Initiator B was prepared by dissolving 1.2 g of ammonium persulfate in 80 g of water. 760g of water, 8g of nonylphenol ethoxylated phosphate (Dextrol TM OC-110), 0.72 g of ammonium carbonate and 1.29 g of 28 wt% ammonium hydroxide were charged into a 3 liter reaction vessel and heated to 80°C. Initiator A was then added to the reaction vessel, followed by the uniform addition of the monomer premix to the reac...

Embodiment 2

[0046] Emulsion polymer B of methacrylic acid, methyl methacrylate, 2-ethylhexyl acrylate, styrene, diacetone acrylamide and AMPS 2405 was prepared by using phosphate ester surfactants:

[0047] By mixing 216g of water, 45.6g of diacetone acrylamide, 1.07g of ammonium lauryl sulfate (Sipon TM L-22), 0.64g ammonium carbonate, 9.6g nonylphenol ethoxylate phosphate (Dextrol TM OC-110), 4 g methacrylic acid, 453.6 g methyl methacrylate, 88.8 g 2-ethylhexyl acrylate, and 200 g styrene to prepare a monomer premix. Initiator A was prepared by dissolving 0.8 g ammonium persulfate in 13.3 g water. Initiator B was prepared by dissolving 1.2 g of ammonium persulfate in 80 g of water. 592g water, 4.8g Dextrol TM OC-110, 0.72 g ammonium carbonate and 1.91 g 28 wt% ammonium hydroxide were charged into a 3 liter reaction vessel and heated to 80°C. Initiator A was then added to the reaction vessel, followed by the uniform addition of the monomer premix to the reaction vessel over a per...

[0049] Preparation of emulsion polymer C of methacrylic acid, methyl methacrylate, 2-ethylhexyl acrylate, styrene, diacetone acrylamide and AMPS 2405 by using phosphate ester surfactants:

[0050] By mixing 216g of water, 45.6g of diacetone acrylamide, 1.07g of ammonium lauryl sulfate (Sipon TM L-22), 0.64g ammonium carbonate, 9.6g tridecyl alcohol ethoxylate phosphate (Dextrol TM OC-40), 4 g methacrylic acid, 453.6 g methyl methacrylate, 88.8 g 2-ethylhexyl acrylate, and 200 g styrene to prepare a monomer premix. Initiator A was prepared by dissolving 0.8 g ammonium persulfate in 13.3 g water. Initiator B was prepared by dissolving 1.2 g of ammonium persulfate in 80 g of water. 592g water, 4.8g Dextrol TM OC-40, 0.72 g ammonium carbonate and 1.91 g 28 wt% ammonium hydroxide were charged to a 3 liter reaction vessel and heated to 80°C.

Abstract

The invention belongs to the field of chemical engineering and relates to water-based coating, in particular to water-based coating for interior and exterior walls of buildings. The water-based coating comprises emulsion copolymer polymerized by at least one type of olefinic bond type unsaturated anion monomer and at least one type of other olefinic unsaturated monomers, wherein the copolymer is prepared by at least one type of phosphate-ester-containing surfactant including at least one phosphate group or salt thereof and is optionally cross-linked. Preferably, the water-based coating for the interior and exterior walls of the buildings further comprises thickener which is an acrylic acid addition polymer with an amine or acid function. The water-based coating for the interior and exterior walls of the buildings is excellent in mechanical property, high in binding power and good in ductility, still has excellent scrubbable performance particularly when high non-transparency is obtained, is high in stability, long in quality guarantee period and high in glossiness and free of bubbles after coating curing, thereby being novel coating which is attractive, practical, safe and environment-friendly.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to water-based paint, in particular to a water-based paint for interior and exterior walls of buildings and a preparation method thereof. Background technique [0002] Coatings used in the construction industry are generally viscous liquid polymer synthetic materials that have no fixed shape at room temperature, and generally include the following two types: The first is solvent-based paints, in which polymer binders are dissolved or dispersed in organic solvents Among them, the commonly used solvent-based paints (paints) have high content of formaldehyde and organic compounds (VOC), and regulators such as thinner must be added during use, which is very polluting to the environment and tends to be eliminated. The second is water-based paints, in which the polymer binder is a dispersion of insoluble polymers in water, commonly known as "latex paint". Latex paints consist of a film-form...
