| titleOfInvention | A kind of polyester resin for high weather resistance and low temperature HAA curing powder coating and preparation method thereof |
| abstract | The invention relates to a polyester resin for powder coatings and a preparation method thereof, and provides a saturated carboxyl-terminated polyester resin for high weather resistance and low temperature HAA curing powder coatings and a preparation method thereof. The above polyester resin consists of the following main components in mass percentage Formed by melt polymerization: polyol component A, polybasic acid component B, esterification catalyst component C, acid hydrolyzing agent component D, acid hydrolyzing agent component E and antioxidant component F; according to the following The steps are as follows: add component A, then add component B and component C, gradually heat up while stirring; melt esterification condensation reaction; add component D and component E, carry out acidolysis reaction successively; reduce compression and condensation reaction; Add component F, stir and react; cool down and discharge, cool and pulverize. The low-temperature HAA-cured powder coating provided by the invention can be cured under the condition of 150°C/15min, and the obtained coating film has excellent weather resistance, as well as good leveling properties and decorative properties such as anti-blooming properties. |
