[0003] Most of the current latex paints are synthetic resin emulsion-based paints, and the varieties are relatively complicated. The most common ones are latex paints made from pure acrylic and styrene acrylic emulsions. However, in the current market, the functions of the paints are relatively single, and it is difficult to provide a paint with high gloss, good weather resistance and waterproofness suitable for building exterior walls.

[0004] In order to solve the problems in the prior art, the object of the present invention is to provide a highly scrub-resistant matte nano interior wall paint and a preparation method thereof.

[0005] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solution:

[0006] A highly scrub-resistant matte nano interior wall paint, the interior wall paint comprises the following components in parts by mass:

[0007] Water, ethylene glycol, dispersant, wetting agent, defoamer, bactericide, rutile titanium dioxide 28%, kaolin, ultrafine talc, nano slurry 12%, hydroxyethyl cellulose, odorless emulsion 30%, film-forming aid, multifunctional additive, leveling agent, thickener.

[0008] Preferably, the defoaming agent is a silicone emulsion defoaming agent.

[0009] Preferably, the film-forming aid is Texanol from Eastman Company, USA.

[0010] Preferably, the components of the nano-slurry are: nano-titanium dioxide, nano-calcium oxide, and nano-silicon oxide.

[0011] A method for preparing a highly scrub-resistant matte nano interior wall paint comprises the following steps:

[0012] S1: Add water, ethylene glycol, dispersant, wetting agent, defoamer and bactericide into a dispersion tank for dispersion;

[0013] S2: adding rutile titanium dioxide, kaolin, ultrafine talc and nano-slurry into a stirring kettle for stirring, grinding after stirring, and then adding into the dispersion tank in step S1 for dispersion;

[0014] S3: Add hydroxyethyl cellulose, odorless emulsion, film-forming aid, multifunctional aid, leveling agent, thickener, defoamer and fungicide into a stirring kettle for stirring;

[0015] S4: Mixing and stirring the mixture in step S2 and the mixture in step S3 to complete the preparation of the multifunctional nano paint.

[0016] Preferably, in step S1, the dispersion is carried out at a rotation speed of 800-1000 r / min for 20 min.

[0017] Preferably, in step S2, the stirring time is 20 min, and the grinding is performed twice.

[0018] Preferably, in step S3, stirring is performed at a rotation speed of 400 r / min for 20 min.

[0019] By adopting the above technical solution, the present invention can produce the following beneficial effects:

[0020] 1. The interior wall paint of the present invention has good properties such as good scrub resistance, water resistance, weather resistance, and leveling.

[0021] 2. The interior wall paint of the present invention has suitable low-temperature film-forming properties. After film formation, the paint can not only form a coating with high hardness and good stain resistance, but also ensure low-temperature film-forming effect with less film-forming aids, and is easy to construct. In addition, the present invention has an excellent matte effect, so that the negative impact on the transparency and anti-graffiti property of the coating is relatively small. DETAILED DESCRIPTION
