The phenolated lignin ended up being used to replace 40 wt% of phenol to prepare a PF glue (PLPF) that has been more utilized to get ready plywood. The results indicated that the mixture of fractionation and phenolation successfully enhanced the reactivity of lignin, and eventually enhanced the properties of this PLPF and its particular corresponding plywood. The no-cost formaldehyde content of PLPF reduced to 0.16percent. The damp bonding power regarding the as-prepared plywood risen to 1.36 MPa, while the emission of formaldehyde reduced to 0.31 mL/L
