Title:
COVALENT ORGANIC FRAME FLAME RETARDANT HAVING SCHIFF BASE-CONTAINING VANILLIN GROUP, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/037273
Kind Code:
A1
Abstract:
Disclosed in the present invention are a covalent organic frame flame retardant having a Schiff base-containing vanillin group, and a preparation method therefor. In the present invention, the covalent organic frame flame retardant is prepared by performing a Schiff base amine aldehyde condensation reaction on a tridentate aldehyde compound containing R2 and a bidentate amine compound containing R1. A bio-based feedstock used in the present invention is environmentally friendly, a Schiff base structure contained in a molecular structure has high thermal stability and uses an amine aldehyde condensation reaction to make a reaction condition be mild, and the formation of a covalent organic structure that is rich in a benzene ring structure can significantly improve the thermal stability of the flame retardant and increasing the amount of formed carbon.
