| titleOfInvention | Synthetic method of semi-crystalline polyester resin with low viscosity and high toughness for powder coating |
| abstract | The present invention relates to a synthetic method of a semi-crystalline polyester resin with low viscosity and high toughness for a powder coating. The purpose of the invention is that paint prepared from the polyester resin obtained by the method should have good leveling property and excellent comprehensive properties. A technical scheme of the synthetic method of the semi-crystalline polyester resin with low viscosity and high toughness for the powder coating accords with the following steps in order: 1) pouring hexanediol into a reactor for normal pressure heating, then adding terephthalic acid and monobutyl tin oxide; and heating with stirring; 2) heating the materials till generation of esterification water, heating to 245+/- 2 DEG C and insulating for reaction; 3) adding diglycol or adipic acid or m phthalic acid, and insulating for reaction; then adding triphenyl phosphite, and trimellitic anhydride or adipic acid or m phthalic acid, and insulating for reaction; 4) vacuum-pumping and insulating for vacuum reaction; after the vacuum reaction, sampling and determining resin acid value; meanwhile cooling, adding NaBA, and stirring with cooling, so as to finish the reaction. |
