Problems solved by technology

At present, the methods of removing wild advertisements mainly include physical methods (shoveling, grinding, etc.) and chemical methods. These methods are time-consuming and laborious, have poor results, and will damage the surface of public facilities coated with small advertisements, and have not achieved real cleaning and beautification. The effect of the city environment

preparation example Construction

[0058] The preparation method of above-mentioned water-based anti-graffiti anti-sticking coating comprises the steps:

[0059] a): Add anionic polyacrylic acid dispersion and water to the container successively, and stir;

[0060] b): Gradually add pigments and functional fillers, increase the speed while adding, and keep stirring;

[0061] c): After the material is completely dispersed, add anionic polyacrylate dispersion, modified organosilane emulsion, and fumed silica, and stir after reducing the rotation speed;

[0062] d): Increase the rotation speed while adding the thickener, stir evenly, and then filter to form component A;

[0063] e): Mix the obtained component A with the curing agent, stir evenly, and after aging for 5 to 10 minutes, the required coating is obtained, and the construction is carried out within the specified time, wherein, in steps a), c), and e) The corresponding additives are added before stirring, and the ratio of materials in each step is the c...

Embodiment 1

[0068] Production of A component:

[0069] Take 30kg of anionic polyacrylic acid dispersion, 0.3kg of dispersant, 0.1kg of wetting agent, 0.2kg of defoamer, 0.2kg of antifungal agent, 3.0kg of water, 15kg of rutile titanium dioxide, 10kg of filler, and disperse and shear at high speed to make slurry material, then add 20kg of anionic acrylic dispersion, 10kg of modified polysiloxane, 2.0kg of fumed silica, 0.3kg of defoamer, 5.0kg of wax emulsion, and then add appropriate amount of associative thickener and leveling agent to adjust To the required viscosity, disperse for 15 minutes, filter and pack.

[0070] In this example, component A: component B = 100:20. According to this ratio, components A and B are mixed and stirred evenly, aged for 5 minutes to form a coating, and then construction is carried out, and the coating is used up within the construction time limit.

Embodiment 2

[0072] Take 20kg of anionic polyacrylic acid dispersion, 0.3kg of dispersant, 0.1kg of wetting agent, 0.2kg of defoamer, 0.2kg of antifungal agent, 5.0kg of water, 15kg of rutile titanium dioxide, 10kg of filler, and disperse and shear at high speed to make slurry material, then add 40kg of anionic acrylic dispersion, 5kg of modified polysiloxane, 2.0kg of fumed silica, 0.3kg of defoamer, 5.0kg of wax emulsion, and then add appropriate amount of associative thickener and leveling agent to adjust To the required viscosity, disperse for 15 minutes, filter and pack.

[0073] In this example, component A: component B = 100:25. According to this ratio, components A and B are mixed and stirred evenly, aged for 5 minutes to form a coating, and then construction is carried out, and the coating is used up within the construction time limit.

Abstract

The invention relates to an aqueous anti-doodling and anti-affixing paint. The paint provided by the invention comprises a component A and a component B, wherein the component A contains, by weight, 50-70 parts of an anionic polyacrylate dispersion and 5-10 parts of a modified silane emulsion; and the component B contains, by weight, 20-25 parts of a water dispersive aliphatic polyisocyanate curing agent. The invention also relates to a preparation method of an aqueous anti-doodling and anti-affixing paint film. With the use of the polyacrylate dispersion as a base material, the aqueous anti-doodling and anti-affixing paint can have a high gloss and its scratch resistance can be improved. With the use of the water dispersive aliphatic polyisocyanate as a cross-linking agent, the paint can have excellent weatherability and yellow-stain resistance. Dual-component crosslinking and solidification can endow the paint with high surface hardness, compact film and excellent anti-doodling performance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based anti-graffiti and anti-sticking coating and a preparation method thereof. Background technique [0002] In recent years, graffiti, graffiti, graffiti, and various small and wild advertisements have attracted more and more people's attention. Graffiti not only affects the city appearance and landscape, but also costs a lot of money to remove graffiti. These graffiti advertisements have always been regarded as "urban psoriasis" that affects the appearance of the city, and have become a chronic disease that is difficult to cure in cities across the country. [0003] There are usually various methods and materials used for graffiti, graffiti, and graffiti. Some use marker pens and other tools to dip paint, ink, etc. to scribble on the surface of public facilities, or use glue, paste, stickers, etc. post etc. These small advertisements are very firmly attached to the surfaces o...
