Title:
BIOMASS INTRINSIC FLAME-RETARDANT HIGH-TEMPERATURE-RESISTANT EPOXY RESIN AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/139651
Kind Code:
A1
Abstract:
Disclosed are a biomass intrinsic flame-retardant high-temperature-resistant epoxy resin and a preparation method therefor. The structural formula of a monomer of the epoxy resin is formula (I). In the present invention, a benzimidazole-like structure is introduced, which itself has an efficient solid-phase flame retardant effect, and which can promote the formation of a carbon layer, which improves the flame retardant performance of the epoxy resin; by introducing the benzimidazole-like structure into the epoxy resin, the benzimidazole-like structure is rigid and a nitrogen atom of a heterocyclic ring can form a hydrogen bond with a side hydroxyl group of the epoxy resin, which will greatly improve the heat resistance of the epoxy resin; and phosphorus-containing and halogen-containing elements are not introduced, and the selected raw material is a biomass platform product, such that the finally obtained epoxy resin is green and environmentally friendly.
