Problems solved by technology

Especially for children's graffiti stains, such as: chalk, color pen, gel pen and other graffiti marks, which cannot be wiped off. At the same time, due to the use of high tg film-forming emulsion, more film-forming additives are required , which increases the VOC content of the coating, which is not conducive to environmental considerations

Embodiment 1

[0048] An interior wall paint for children that can be used for graffiti, which is prepared from component A and component B at a mass ratio of 5:1, wherein:

[0049] Component A is prepared from the following raw materials in weight percentage:

[0050]

[0051] Component B is prepared from the following raw materials in weight percentage:

[0052] water 50%;

[0053] Aqueous HDI 50%.

[0054] Hydroxy acrylic emulsion SA626 is used as a film former to wrap pigments, fillers and color pastes. Its solid content is 40%, the pH value is 8.0, and the OH value is 3.5. This lotion is durable, quick drying, high hardness, high adhesion.

[0055] The fineness of glass powder is 1000-2500 mesh. The Mohs hardness reaches 6.0, which can effectively enhance the hardness of the paint film and improve the scratch resistance of the paint film.

[0056] Water-based color pastes are carbon black, iron yellow, iron red and other color pastes according to color requirements.

Abstract

The invention discloses an interior-wall children coating for scribbling. The coating is prepared from a component A and a component B according to the mass ratio of 5:1. The component A is prepared from water, a bactericide, an antibacterial agent, a dispersant, an antifoaming agent, a rheological aid, a coalescing agent, hydroxypropyl methyl cellulose, a hydroxyl acrylic emulsion, titanium dioxide, glass powder and water-based color paste. The component B is prepared from water and water-based HDI. The bactericide is an isothiazolinone bactericide PX-20. The antibacterial agent is a silver ion antibacterial agent CF-8. The hydroxyl acrylic emulsion SA626 is used as a film forming matter, the solid content is 40%, pH value is 8.0, and OH value is 3.5. Fineness of the glass powder is 1000-2500 meshes. Moh's hardness reaches 6.0. The water-based HDI is hexamethylene diisocyanate (HDI)-based hydrophilic aliphatic polyisocyanate, and NCO content is 20-21%. The invention also discloses a preparation method of the interior-wall children coating for scribbling. The Interior-wall children coating for scribbling has good paint film hardness and broad-spectrum long-acting antibacterial effect, and meets environment-protection requirement of children rooms.

Description

[0001] Technical field: [0002] The invention relates to the field of interior wall coatings for civil buildings, and relates to a children's interior wall coating which can be used for writing and a preparation method thereof for wall decoration of children's rooms, and belongs to the field of architectural coatings. [0003] Background technique: [0004] At present, the interior wall latex paint used for interior decoration has main performances in terms of environmental protection and deodorization, etc., but the protection performance for the wall is insufficient, especially the effect in terms of stain resistance is very unsatisfactory. [0005] In recent years, there have been some stain-resistant products for indoor walls, using some high-tg film-forming emulsions and some high-hardness fillers (such as glass powder, ceramic powder, etc.). The types of stains that these coatings can resist are very small, limited to dust, water stains, etc. Especially for children's g...
