| titleOfInvention | Silicone-modified carboxylic acid/sulfonic acid type waterborne polyurethane for leather finishing agent and method thereof |
| abstract | The invention belongs to the field of finishing agents, and discloses an organosilicon-modified carboxylic acid/sulfonic acid type water-based polyurethane for leather finishing agents and a method thereof. The water-based polyurethane is prepared from components in mole fractions, a neutralizer and water: the components in mole fractions are: 10-30 parts of oligomer polyol, hydroxyl-terminated polyether modified 6-20 parts of silicone oil, 0.01-0.06 parts of catalyst, 30-60 parts of polyisocyanate, 3-6 parts of carboxyl chain extender, 2-8 parts of sulfonate chain extender, 1-10 parts of small molecular diamine; The dosage of the neutralizing agent is 0.11-1.1 times of the total molar amount of the carboxyl chain extender and the sulfonate chain extender. The prepared water-based polyurethane has good stability, long storage time and good water resistance of the coating film. In a word, the water-based polyurethane of the present invention is environmentally friendly, has excellent performance and good effect. |
