Abstract:

A hydrogenolysis process was performed for regenerated bamboo lignin after ［AMIM］OAc pretreatment by using a high-pressure batch autoclave with a rotation rate of 450r/min in 2MPa H 2 atmosphere at 260℃ for 80min,and a GC-MS analysis was conducted,finding that most hydrogenolysis products of lignin (HPL) are phenolic com- pounds with short chains or aromatic compounds containing phenol hydroxyl.Then,HPL was used as a substitution for phenol to synthesize phenol-furfural resins (PFU),and the effects of substitution rate of HPL for phenol on the bond strength,solid content,curing time,free formaldehyde content,free phenol content and viscosity of PFU were investigated.The results show that，at a substitution rate of 60%,the lignin-based PFU is of a bond strength up to 2. 06MPa as well as a free phenol content lower than those regulated by Chinese national standards,and the curing time greatly shortens.Moreover,DSC results indicate that the lignin-based PFU possesses strong thermosta- bility.
