Title:
POLYESTER MATERIAL AND POLYESTER PRODUCT, AND PREPARATION METHODS THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/173791
Kind Code:
A1
Abstract:
Disclosed in the present application are a polyester material and a polyester product, and preparation methods therefor and the use thereof. The preparation method comprises: reacting a dibasic acid and/or a dibasic acid ester, a dihydric alcohol, a two-dimensional MXene material catalyst, a second catalyst and a stabilizer to prepare a polyester material; or melting and blending a polyester, a two-dimensional MXene material and an auxiliary agent to prepare a polyester material. In the present application, a two-dimensional MXene material is added as a catalyst and a nucleating agent during the preparation process of a polyester, wherein the two-dimensional MXene material not only functions as a high-activity catalyst, but also functions as an efficient nucleating agent to significantly increase the crystallization rate of the polyester; alternatively, a two-dimensional MXene material is blended and added into a polyester, such that the MXene material is better dispersed in the polyester, and the obtained polyester material has high heat resistance, a rapid crystallization property, excellent mechanical properties and impact resistance, and can be widely applied in the fields of engineering plastics, optical films, industrial wires, food packaging materials, etc.
