Title:
BIO-BASED INTRINSIC FLAME-RETARDANT EPOXY RESIN PRECURSOR EMPLOYING NATURAL FLAVONOID COMPOUND, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/097875
Kind Code:
A1
Abstract:
Disclosed is a bio-based intrinsic flame-retardant epoxy resin precursor employing a natural flavonoid compound and an application thereof in the preparation of an epoxy resin. The precursor has a structure as shown in formula (I) and formula (II). Further disclosed is a preparation method for the bio-based intrinsic flame-retardant epoxy resin precursor, comprising: reacting a natural flavonoid compound with epichlorohydrin in one step to prepare the bio-based intrinsic flame-retardant epoxy resin precursor. The present invention features a simple preparation process, good controllability, and easy implementation, and is suitable for large-scale industrial production. A thermosetting epoxy resin obtained after curing of the bio-based intrinsic flame-retardant epoxy resin precursor of the present invention has excellent thermodynamic properties and flame-retardant properties, has the potential of replacing existing petroleum-based high-end epoxy products, and has a wide range of applications.
