preparation example Construction

[0041] The present invention provides the preparation method of interior wall paint described in above-mentioned scheme, comprises the following steps:

[0042] Dissolving the cellulose in part of the water, and then performing the first mixing with the water-based dispersant, part of the water-based defoamer, water-based wetting agent, film-forming aid and neutralizing agent to obtain the first mixture;

[0043] The first mixture is mixed with rutile titanium dioxide, mica powder, calcined kaolin, talcum powder, and heavy calcium for a second time to obtain a second mixture;

[0044] The second mixture is mixed with the water-based special emulsion, the remaining water-based defoamer, bactericide and antifreeze to obtain the third mixture;

[0045] The third mixing material, the thickener and the neutralizing agent are mixed for the fourth time, so that the pH value of the mixing material reaches 7.5-9, and then the remaining water is added to obtain the interior wall water p...
