<p>The invention relates to a phosphogypsum-based acrylic paint, pertaining to the field of industrial chemistry; despite phosphogypsum being reused in the production of materials for premoulded construction, owing to the high level of phosphogypsum waste generated, the current market is not capable of reutilizing the substance adequately; with a view to resolving this drawback, the subject matter of the present application was developed, which is constituted by a micronized phosphosypsum-based acrylic paint (CASO4 NH2O), which has the following chemical composition (100% (one hundred per cent) weight per cent), in the following order: 1 - water, 47.850 per cent; 2 - wetting agent, 0.200 per cent; 3 - dispersing agent, 0.400 per cent; 4 - antifoam, 0.100 per cent; 5 - bactericide, 0.200 per cent; 6 - sodium nitrite, 0.030 per cent; 7 - phosphogypsum (from 5 to 10 mum), 40.000 per cent; 8 - mixing substances 1 to 7 for two minutes; 9 - alcalinizing agent, 0.350 per cent; 10 - pigment, 2.500 per cent; 11 - butyl glycol, 0.750 per cent; 12 - white spirit, 1.200 per cent; 13 - dispersion for 20 (twenty) minutes, etc.</p> |
