| titleOfInvention | Preparation method of waterborne polyurethane emulsion for temperature-resistant transfer coating |
| abstract | The invention discloses a preparation method of waterborne polyurethane emulsion for temperature-resistant transfer paint, which has the technical scheme key points that the preparation method comprises the following steps: under the protection of dry nitrogen, 6-14% of oligomer polyol is dehydrated and vacuumized for 1 hour at the temperature of 100-110 ℃, and then cooled to 50-60 ℃; adding 10-12% of diisocyanate, automatically releasing heat, heating to 85 +/-3 ℃, reacting for 2 hours, and cooling to 52-54 ℃; mixing 12-16% of hydrophilic chain extender, 1.5-3% of cross-linking agent and 2-4% of NMP, and reacting for 1 hour at 70-75 ℃; adding 0.006-0.012% of catalyst, and reacting for 2 hours at 60-65 ℃; cooling, adding 12-18% of acetone, cooling to below 30-35 ℃, adding an amine chain extender, and dispersing for 1 minute; adding a neutralizing agent and ice pure water within 1 minute, and dispersing at a high speed for 20 minutes; vacuumizing and removing the solvent to obtain the waterborne polyurethane emulsion for the temperature-resistant transfer coating; the synthesis process is simple, the particle size of the emulsion is appropriate, the production quality is good, and the heat resistance is good. |
