| titleOfInvention | A kind of low acid value polyester resin for ultra-low temperature curing powder coating and preparation method thereof |
| abstract | Provided are a low-acid value polyester resin for ultra-low temperature curing powder coatings and a preparation method, which adopts the raw material triethylene glycol of the flexible segment, and the liquid multifunctional raw material glycerol and triisopropanolamine as the main raw materials, and the raw material of the flexible segment is used. Phthalic acid and sebacic acid carry out chain extension reaction, and finally use highly active polyisobutylene succinic anhydride for end capping, and the end capping segment of the final polyester resin exists in the form of partial acid anhydride, although the acid value is low, but the acid anhydride activity is very high. The acid value of the obtained polyester resin is controlled at 16-20mgKOH/g, the softening point is 87-95°C, ultra-low temperature curing can be achieved under the curing condition of 135°C/20min, and the coating film performance completely reaches that of the general-purpose TGIC coating film.
