Randomized trial assesses plywood bonding strengths with lignin-based adhesive, indicating performance improvements with novel fillers.

This study aims to develop a greener lignin-formaldehyde resin as a wood adhesive and evaluate the effects of a novel filler on plywood performance.
Produced lignin formaldehyde resin by replacing phenol with lignin using Elbs persulfate oxidation with potassium persulfate and varying sodium hydroxide concentrations.
Analyzed reactive lignin characteristics through acid-base titration, NMR, GPC, and FTIR methods.
Evaluated plywood bonding strengths under dry and wet conditions using LF resin with trimethyl stearyl amine-montmorillonite filler.
Dry bonding strength for LF resin with TMSA-MMT was 6.15 MPa, and wet strength was 2.2 MPa, compared to PF resin at 8.10 MPa dry.
The free formaldehyde levels in LF and LF/TMSA-MMT were 0.25% and 0.06%, respectively, meeting the GB/T 14732-2006 standard (≤ 0.3%).
The use of TMSA-MMT as filler improved plywood performance while maintaining lower formaldehyde emissions.
