| Résumé : |
Bamboo shavings, a waste of bamboo processing, contain many active groups and have excellent potential for the preparation of a biomass adhesive. In this study, under the catalysis of phenol and sulfuric acid, bamboo shavings are subjected to microwave treatment. The bamboo fibres are degraded and liquefied into a solid and liquid mixture (as a native putty of adhesive). The composite adhesive is prepared by mixing degraded collagen (Co) with the degradation mixture and cross-linking with epichlorohydrin.
Some key quality indexes of plywoods such as the bonding strength, the modulus of rupture (MOR) and the modulus of elasticity (MOE) of prepared plywoods meet the quality index requirements of plywood (GB/T 9846-2015, China). Experimental analysis shows that the good bonding properties correlated well with 5-hydroxymethylfurfural (5-HMF) in the bamboo degradation liquid and the Maillard reaction of collagen degradation bonds between the polar groups. |
