Embodiment 1

[0047] Example 1: A scrub-resistant finish paint for interior walls, the components and their corresponding parts by weight are shown in Table 1, and are prepared through the following steps:

[0048] Step 1, adding corresponding parts by weight of deionized water, sodium tripolyphosphate and polydimethylsiloxane into the reaction vessel, the stirring speed is 400rpm, and the time is 4min;

[0049] Step 2, continue to add corresponding parts by weight of styrene-acrylic emulsion, silicone resin, hydroxyethyl methacrylate, methacrylic acid and butyl acrylate to the reaction vessel, the stirring speed is 1100rpm, and the time is 25min;

[0050] Step 3, then adding ultra-fine aluminum silicate in corresponding parts by weight to the reaction vessel, the stirring speed is 1350rpm, and the time is 15min;

[0051] Step 4: Finally, add Tex film-forming agent, PT86 antifungal agent and sodium carboxymethyl cellulose in corresponding parts by weight, and stir at 650 rpm for 12.5 minute...

Embodiment 2

[0053] Embodiment 2: A kind of interior wall anti-scrubbing finish paint, differs from Embodiment 1 in that it is mainly prepared through the following steps:

[0054] Step 1, adding deionized water, sodium tripolyphosphate and polydimethylsiloxane in corresponding parts by weight into the reaction vessel, the stirring speed is 300rpm, and the time is 5min;

[0055] Step 2, continue to add corresponding parts by weight of styrene-acrylic emulsion, silicone resin, hydroxyethyl methacrylate, methacrylic acid and butyl acrylate to the reaction vessel, the stirring speed is 900rpm, and the time is 30min;

[0056] Step 3, then adding corresponding parts by weight of superfine aluminum silicate to the reaction vessel, the stirring speed is 1200rpm, and the time is 20min;

[0057] Step 4: Finally, add Tex film-forming agent, PT86 fungicide and sodium carboxymethyl cellulose in corresponding parts by weight, and stir at 500 rpm for 15 minutes to obtain a scrub-resistant finish for int...

Embodiment 3

[0058] Embodiment 3: a kind of interior wall anti-scrubbing finish paint, differs from embodiment 1 in that it is mainly prepared through the following steps:

[0059] Step 1, adding corresponding parts by weight of deionized water, sodium tripolyphosphate and polydimethylsiloxane into the reaction vessel, the stirring speed is 500rpm, and the time is 3min;

[0060] Step 2, continue to add corresponding parts by weight of styrene-acrylic emulsion, silicone resin, hydroxyethyl methacrylate, methacrylic acid and butyl acrylate to the reaction vessel, the stirring speed is 1300rpm, and the time is 20min;

[0061] Step 3, then adding ultra-fine aluminum silicate in corresponding parts by weight to the reaction vessel, the stirring speed is 1500rpm, and the time is 10min;

[0062] Step 4: Finally, add Tex film-forming agent, PT86 antifungal agent and sodium carboxymethyl cellulose in corresponding parts by weight, stirring at 800 rpm for 10 minutes, to obtain an interior wall scrub...

Abstract

The invention discloses an interior wall scrubbing-resistant top coat and a preparation method thereof, relates to the technical field of aqueous coating materials. In the prior art, the paint film iseasily damaged after frequent scrubbing due to poor scrubbing resistance of the interior wall top coat. A purpose of the invention is to solve the problem in the prior art. The interior wall scrubbing-resistant top coat comprises, by weight, 25-40 parts of a styrene-acrylic emulsion, 15-20 parts of deionized water, 0.4-0.8 part of a dispersing agent, 0.3-0.5 part of a defoaming agent, 0.6-0.9 part of a thickening agent, 8-12 parts of a pigment filler, 5-10 parts of an organic silicon resin, 0.5-0.9 part of a Tex film forming agent, 0.2-0.6 part of a PT86 mildew-proof agent, 3-6 parts of hydroxyethyl methacrylate, 1-2 parts of methacrylic acid, and 4-6 parts of butyl acrylate. According to the invention, after the interior wall scrubbing-resistant top coat is used, the formed paint film has good scrubbing resistance and is not prone to damage, and the overall application effect is good.

Description

technical field [0001] The invention relates to the technical field of water-based coatings, in particular to a scrub-resistant finish paint for interior walls and a preparation method thereof. Background technique [0002] Wall paint is top paint, which is often called latex paint. It is one of the main decorative materials used for wall surface in home decoration, and it accounts for a considerable proportion of basic decoration costs. It is very important to choose high-quality wall paint. In order to achieve the purpose of bonding, the main component of wall paint is resin, which can be firmly bonded to the wall. [0003] In the Chinese invention patent with the publication number CN104962186A, a kind of interior wall paint with energy saving, environmental protection and soft hand feeling is disclosed, which is composed of polyurethane dispersion, wetting agent, dispersant, rutile titanium dioxide, diatom It is prepared from soil, expanded microspheres, film-forming ai...
