Embodiment 1

[0050] This embodiment provides a mother liquor of a textured paint and a preparation method thereof, comprising the following steps:

[0051] Step 1. Weigh each raw material according to the following weight percentages.

[0052] Water 32.15%, acrylic emulsion RS998A 51.83%, non-ionic polyacrylamide VA4058FC 0.3%, cellulose HK75000S 0.66%, propylene glycol 1%, polyacrylic acid sodium salt PA30 0.72%, film-forming agent (alcohol ester-12) 1.95% , defoamer CF-246 0.19%, titanium dioxide 9.72%, EPW antifungal agent 0.64%, LXE fungicide 0.64%.

[0053] Among them, the polyacrylamide is a nonionic polyacrylamide with a molecular weight of 3 million.

[0054] Step 2, mixing and dispersing.

[0055] Put polyacrylamide, alcohol ester-12, propylene glycol, cellulose HK75000S, polyacrylic acid sodium salt PA30 and 0.26% defoamer CF-246 into water and disperse for 10-15 minutes, stir until there are no particles, then add titanium dioxide and EPW anti-foaming agent Mold agent, adjust...

Embodiment 2-3 and comparative example 1-2

[0057] Referring to the preparation method of the texture paint mother liquor in Example 1, according to the raw materials and their dosages in Table 1, prepare the texture paint mother liquors of Examples 2-3 and Comparative Example 1-2.

[0058] Table 1

[0059]

[0060] performance test 1

[0061] Using JG / T24-2000 "Synthetic Resin Emulsion Sand Wall Architectural Coatings" standard, the viscosity, freeze-thaw stability and heat storage stability of the texture paint mother liquors of Examples 1-3 and Comparative Examples 1-4 were tested.

[0062] The test results are shown in Table 2.

[0063] Table 2

[0064]

[0065] It can be seen from Table 2 that in Examples 1-3 and Comparative Example 4, after adding nonionic polyacrylamide and anionic polyacrylamide, the viscosity of the mother liquor decreased significantly, which provided very convenient conditions for the transportation of the mother liquor, and the polyacrylamide The network structure can improve the ...

Embodiment 4

[0086] This embodiment provides a textured paint and a preparation method thereof, comprising the following steps:

[0087] Step 1. Weigh each raw material according to the following weight percentages.

[0088] Mother liquor 33% of embodiment 1, thickener TT-615 0.3%, water 8.2%, pH regulator AMP95 0.1%, diatomite Celabrite 7.5%, 100 mesh expanded perlite 0%, 200 mesh sand 27%, 16 - 30 mesh sand 26%, 3mm polyester fiber 0.5% and defoamer CF-246 0.1%.

[0089] Step 2. Mix and disperse the above-mentioned raw materials to obtain the product.

Abstract

The invention relates to a texture coating. The texture coating comprises the following raw materials in percentage by weight: 11 to 25% of an acrylic emulsion, 0.08 to 0.14% of polyacrylamide, 0.09 to 0.28% of cellulose, 0.3 to 0.5% of propylene glycol, 0.3 to 0.6% of an associative thickening agent, 52-70% of a filler, 2.6-8% of other processing aids and 9-20% of water, wherein the polyacrylamide is non-ionic polyacrylamide, and has a molecular weight of no greater than 3 million; and the solid content of the acrylic emulsion is 45%-60%. The texture coating is good in moisture retention, convenient to construct, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the field of architecture, in particular to a texture coating and a preparation method thereof. Background technique [0002] Texture paint is currently a popular architectural paint. Because of its personalized decoration, it can create different shapes and patterns, and achieve a real, beautiful and generous texture effect. It is widely loved by everyone. As the application range of texture coatings becomes wider and wider, more problems are exposed. [0003] Poor water retention of texture coatings will result in short opening time of the product, which is not conducive to construction. Starch ether and cellulose have been publicly used as humectants. However, when starch ether dissolves in water, it is very easy to agglomerate and has a darker color. However, the water retention of cellulose is slightly poor, and a large amount of addition will lead to large construction resistance and limited application. And when prepar...
