| titleOfInvention | A kind of water-based polyaspartic acid ester dispersion, its preparation method and water-based polyurea coating resin |
| abstract | The invention belongs to the technical field of coatings, and in particular relates to an aqueous polyaspartate dispersion, a preparation method thereof and an aqueous polyurea coating resin. The method includes steps: 1) dehydrating polyetheramine and polyaspartate resin at 100°C-120°C under negative pressure; 2) after step 1) is completed, cooling down to 20°C-60°C, dripping at a constant speed Add diisocyanate, the dropping time is controlled at 0.5h-1.5h, and the solvent is added, and after the dropping is completed, the temperature is raised to 40 ℃-80 ℃, and the reaction is held at a constant temperature; 3) After the completion of step 2), slowly add the preheated The ionized water was added dropwise for 0.5h-1.5h, then continued to be stirred for about 0.4h-0.6h, cooled down and discharged, to obtain the water-based polyaspartate dispersion. The water-based polyaspartate dispersion prepared by the invention has low VOC content, is safe, non-toxic and environmentally friendly, and the polyurea coating formed by compatibility with the water-based polyisocyanate has excellent comprehensive performance. |
