Plant protein-based bamboo-wood adhesive, preparation method thereof and application thereof in thin-flake board
By introducing aldehyde-modified pullulan and ellagic acid into plant protein-based bamboo and wood adhesives, an organic-inorganic hybrid triple cross-linked network structure is formed, which solves the problem of insufficient flame retardancy of protein-based adhesives and achieves high-efficiency flame retardancy and improved structural stability of the boards.
