preparation example Construction

[0073] The preparation method of water-based anti-graffiti coating includes steps such as premixing, grinding and dispersing, adding emulsion and adding additives, and its specific process steps are as follows:

[0074] (1). Pre-mixing: Add the above-mentioned parts by weight of water, dispersant, defoamer and wetting agent into the dispersing tank, stir and mix well to facilitate the dispersion of fillers. The stirring speed is controlled at 300-500RPM.

[0075] (2). Grinding and dispersing: Add the above-mentioned glass powder in parts by weight, beating and grinding for 15-20 minutes under high-speed dispersion, so that the fineness of the color paste is qualified when it is below 50um, and the filler particles are stirred at a high shear rate at high speed. Under the action, it is dispersed into primary particles, and a stable state of dispersion is obtained under the action of the dispersing aid system. The speed of beating and grinding is controlled at 1500-2000RPM.

Abstract

The invention discloses an aqueous anti-doodling paint, which consists of antifouling functional materials, assistants, glass powder filling and water, wherein the antifouling functional materials comprise pure acrylic ester emulsion, wax emulsion and fluorine-type assistant; and the assistants comprise dispersant, wetting agent, film-forming assistant, anti-freezing agent, defoaming agent, thickening agent, mildew-proof agent and preservative. The preparation method of the invention comprises steps of premixing, grinding and dispersing, emulsion adding, assistant adding, packing and the like. The aqueous anti-doodling paint has good antifouling and anti-doodling functions, wherein the VOC content is 52 to 65 g / L, the content of benzene series substance is less than 300 mg / kg, and the contents are far below the index values of volatile organic compounds of solvent products; and the aqueous anti-doodling paint is suitable for indoor space. Moreover, the paint film is compact; meanwhile the paint has the capacities of resisting seepage and reducing the adhesion of pollutants; and particularly aiming at the substances such as children water color pens, crayons, color pencils, ball pens, ink, coffee, tomato sauce, tea juice, shoe print and the like, the pollutants can be easily scrubbed.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based anti-graffiti coating with an anti-pollution function and a preparation method thereof. Background technique [0002] Children have the potential and talent to create, and they should be provided with enough space to encourage them to express what they think and feel at any time, freely, easily and happily, so as to improve children's creativity. Therefore, the paint used for wall decoration in children's rooms or families with children should have anti-pollution properties. [0003] The main pollution of children's brushes is penetration and adhesion, such as children's watercolor pens, crayons, colored pencils, ballpoint pens, ink, coffee, ketchup, tea juice, shoe prints, etc. Ordinary anti-fouling interior paints do not have sufficient resistance to penetration of pollutants and resistance to adhesion. And the better anti-pollution paint of existing effect is oily paint...
