| titleOfInvention | Water-soluble polyester imide insulating paint and preparation method thereof |
| abstract | The invention discloses a water-soluble polyester imide insulating paint which comprises the following components in parts by weight: 145-200 parts of dibasic acid and/or dibasic acid anhydride, 7.5-16 parts of polybasic acid anhydride, 90-160 parts of dihydric alcohol, 18-55 parts of polyhydric alcohol, 2-8 parts of diamine and 18-23 parts of tertiary carboxylic acid glycidyl ester, wherein the dihydric alcohol comprises hydrophilic functional dihydric alcohol, and the hydrophilic functional dihydric alcohol is dihydric alcohol containing carboxyl and/or sulfonic acid groups. According to the invention, hydrophilic functional dihydric alcohol and polyhydric alcohol are introduced into a polyester imide molecular chain, so that the molecular chain contains a certain amount of hydroxyl, carboxyl and/or sulfonate groups, thereby endowing the whole polyester imide molecular chain with water solubility and providing cross-linking points of intermolecular cross-linking reaction, and further improving the performances such as mechanical strength, heat resistance, water resistance, storage stability and the like. The invention also provides a preparation method of the water-soluble polyester imide insulating paint. |
