| titleOfInvention | A kind of preparation method of polyester material, polyester film and preparation method thereof |
| abstract | The invention relates to a preparation method of a polyester material, a polyester film and a preparation method thereof, and belongs to the technical field of the polyester film used for solar battery backplane films. To solve the existing problems of poor flame resistance and heat and humidity resistance, a polyester film is provided, the polyester film includes a surface layer one, a core layer and a surface layer two, the core layer contains polyester chips and masterbatch polyester Slicing, the core layer also contains a modified high heat and humidity resistance flame retardant polyester material. Under the action of a catalyst, the purified terephthalic acid and diols undergo esterification reaction, and after the reaction, a precondensation reaction is carried out; when the characteristics When the viscosity reaches 0.20-0.30g/dl, add reactive phosphorus-based flame retardant to increase the vacuum for polycondensation reaction; when the intrinsic viscosity reaches 0.50-0.65g/dl, add chain extender ADR and anti-hydrolysis agent aromatic polycarbonate Diimine, copolymerization reaction, obtains modified polyester material with high heat resistance and flame retardancy. At the same time, it has the advantages of high flame resistance and heat and humidity resistance. |
