Embodiment 1

[0074] Embodiment 1: a kind of water-based coating, wherein component is as shown in table 1, and obtains by following steps preparation:

[0075] Step 1, mix water, pH adjuster BS168, bactericide (isothiazolinone bactericide), polyacrylic acid sodium salt dispersant, wetting agent CA-09 and 0.2 parts of silicone defoamer, stirring speed is 500rmp, stirring Time is 15min, forms the first mixture with certain viscosity;

[0076] Step 2, adding fillers to the mixture obtained in step 1, the fillers include titanium dioxide R996, calcined kaolin, and nanometer heavy calcium carbonate, and fully disperse for 30 minutes to obtain the second mixture;

[0077] Step 3, add corresponding parts by weight of hydroxyethyl cellulose Natrosol HE-3KB, ethylene-vinyl acetate copolymer emulsion, thickener RM8W and 0.15 parts of silicone defoamer to the second mixture obtained in step 2, stir The speed is 1550-2380rmp, the stirring time is 23-30min, and the filter is 200-250 mesh to form a wat...

Embodiment 2-4

[0078] Embodiment 2-4: A water-based paint, the difference from Embodiment 1 is that the components and their corresponding parts by weight are shown in Table 1.

Abstract

The invention discloses an aqueous coating and a preparation technology thereof. The aqueous coating comprises, by weight, 20-28 parts of an ethylene-vinyl acetate copolymer emulsion, 1.2-1.8 parts of hydroxyethyl cellulose Natrosol HE-3KB, 0.5-1 part of a pH adjuster BS168, 0.35-0.6 parts of an organosilicon antifoaming agent, 30-51 parts of a filler, 2.1-5.2 parts of a dispersant, 0.15-3 parts of a bactericide, 0.1-0.15 parts of a thickener RM8W and 12-18 parts of deionized water; the filler comprises at least three of titanium dioxide R996, calcined kaolin, nanometer heavy calcium carbonate, silica and calcium oxide; and the dispersant comprises at least one of sodium polyacrylate, a wetting agent CA-09 and a wetting agent Hydropalat 436. The aqueous coating has the advantages of good bonding strength, good pseudoplasticity, good scrubbing resistance and good weather resistance.

Description

technical field [0001] The invention relates to the technical field of decoration materials, more specifically, it relates to a water-based paint and a preparation process thereof. Background technique [0002] Water-based coatings use water instead of solvents, which can greatly reduce VOC emissions from about 70% of solvent-based paints to less than 15%. Its environmental acceptability is much higher than that of solvent-based paints, and it saves oil. resources, reduce fire hazards, and improve the operating environment. [0003] The Chinese patent with the authorized announcement number CN102827523B and the authorized announcement date of September 23, 2015 discloses a wall paint. The components and contents are as follows in terms of weight percentage: water 18-30%, titanium dioxide R99615-20% , 5-15% of natural inorganic materials, 3-5% of synthetic sodium aluminosilicate, 1-2% of minerals with Na negative ions, 30-45% of pure acrylic emulsion, 3%-5% of styrene-acryli...
