| titleOfInvention | A kind of polyester resin for self-leveling powder coating and preparation method thereof |
| abstract | A polyester resin for self-leveling powder coatings and a preparation method are provided. The polyester resin is prepared with pentaerythritol, adipic acid, glycerin, terephthalic acid, isooctanoic acid, n-butyric acid, diethylene glycol diglycidyl ether and Methylmalonic acid is used as the main raw material, and a one-time low-temperature curable self-leveling powder coating polyester resin is obtained by segmental polymerization. The polyester structure has an appropriate amount of ester groups with low surface tension, which reduces the softening point of the product and realizes low-temperature curing. Moreover, due to its excellent self-leveling property, it overcomes the problem of insufficient leveling of the low-temperature curing coating film, and obtains Super high leveling film. The preparation process does not need to prepare special raw materials in advance, and the 70/30 self-leveling polyester resin product is directly prepared by a single-pot synthesis process, with simple process and low cost. |
