preparation example Construction
[0029] The preparation method of the solid construction paint provided by the present embodiment may further comprise the steps:
[0030] Mix the excipient, humectant, and deionized water according to weight percentage, heat to a first predetermined temperature, and dissolve to obtain a first solution;
[0031] Adding a neutralizing agent to the first solution, raising the temperature to a second predetermined temperature, keeping the temperature for a predetermined time, so that the reaction is sufficient to obtain a second solution;
[0032] Add water-based paint to the second solution, and disperse evenly to obtain the third solution;
[0033] Pour the third solution into the mold, cool and shape to obtain the coating.
[0034] Preferably, the step is to mix the excipient, humectant, and deionized water by weight percentage, heat to a first predetermined temperature, and dissolve to obtain the first solution, and the first predetermined temperature is 60°C to 70°C;
[003...
preparation example 1
[0039] Mix 8% excipient by weight, 8% moisturizer by weight, and 21.28% deionized water by weight, heat to the first predetermined temperature of 60°C to 70°C, and dissolve; add 2% by weight % neutralizer, the temperature rises to 90°C-95°C, and the reaction is kept for 20-60 minutes to make the reaction fully; add 60.72% by weight of latex paint to obtain a uniformly dispersed solution; keep the temperature at 90°C-95°C , pour the solution into the mold, cool and shape to get solid interior wall latex paint. Herein, the weight percentage refers to the weight percentage of the raw material components and the solid coating, such as the weight percentage of stearic acid and the solid coating.
[0040] The latex paint can be any known latex paint in the art. But in this embodiment, the latex paint preferably includes the following components: 1.5 parts of propylene glycol, 0.2 parts of wetting agent, 1.5 parts of dispersant, 0.1 part of bactericide, 0.3 part of defoamer, 0.1 par...
preparation example 2
[0042] Mix 8% by weight of excipients and 8% by weight of humectants, heat to the first predetermined temperature of 60°C to 70°C, and dissolve; add 2% by weight of neutralizers, and raise the temperature to 90 ℃~95℃, keep warm for 20 minutes~60 minutes to make the reaction fully; add water-based industrial paint with a weight percentage of 82% to obtain a uniformly dispersed solution; keep the temperature at 90℃~95℃, pour the solution into the abrasive tool, Cool and form to obtain a solid water-based high-gloss white finish.
[0043] The water-based industrial paint can be any known water-based industrial paint in the art. But in this embodiment, the water-based industrial paint preferably includes the following components: 66 parts of water-based polyurethane dispersion, 0.6 part of 20% triethylamine, and 15.4 parts of titanium dioxide.
