| titleOfInvention | A kind of water-boiled outdoor polyester resin and preparation method thereof |
| abstract | The invention provides a water-boiled outdoor polyester resin, comprising 15-20% neopentyl glycol, 15-20% 2-ethyl-3-propyl-1, 3-propylene glycol, 7-10% 1,4-butanediol, 0.7-5% trimethylolpropane, 35-45% purified terephthalic acid, 2-15% isophthalic acid, 5-10% 1,4- Cyclohexanedicarboxylic acid, 0.02-0.15% monobutyltin oxide, 1.3-5% adipic acid, 0.1-1% cure accelerator and 0.3-1% antioxidant. The water-boiled outdoor polyester resin of the present invention adds 2-ethyl-3-propyl-1,3-propylene glycol to the raw materials of the polyester resin formulation, and the ethyl and propyl groups on the side chain strengthen the polyester resin's properties. Hydrophobicity, improve the hydrolysis resistance of polyester resin. In the invention, the polyol monomer and the polybasic acid monomer are coordinated and reacted together with trimethylolpropane, and the feeding sequence is adjusted and controlled by the content of each component, so that the esterification reaction speed is fast, the by-products are few, and the molecular weight distribution is concentrated; Ester resin has good weather resistance, boiling resistance and friction resistance. |
