| titleOfInvention | A kind of preparation method and application of nano titanium catalyst for polyester synthesis |
| abstract | The invention relates to a preparation method and application of a nano-titanium-based catalyst for polyester synthesis. First, a nano-titanium catalyst precursor (prepared by using polystyrene-acrylic acid to modify polyacrylamide-wrapped nano-titanium) is mixed with melamine. The grafted graphene oxide is mixed evenly and then hydrothermally reacted to obtain a nano-titanium catalyst, and then the nano-titanium catalyst is modified with a phosphate ester to obtain a nano-titanium catalyst for polyester synthesis; the application is: synthesizing polyester The nano-titanium catalyst is used as the catalyst for polyester synthesis; the chromaticity L value of the synthesized polyester is 86.3~89.9, the b value is 1.6~3.5, and the intrinsic viscosity is 0.65~0.67dL/g. The nano-titanium catalyst for polyester synthesis prepared by the invention has excellent catalytic ability; the polyester produced by using the catalyst has good color system, excellent viscosity and good spinning performance. |
