“…The penetration of the flame retardant into the cell walls is closely related to the improvement in flame retardancy and smoke suppression [ 26 ]. Prior research claimed that parenchyma cells have thinner cell walls and lots of pits, which are beneficial for causing deeper adhesive penetration [ 27 ]. However, the presence of an attached flame-retardant coating on the cell lumen filled up these pits, which hindered the direct and effective contact between the bamboo strips and adhesives on the bonding interfaces, leading to reduced bonding strength and bending properties.…”

This study investigated the effects of different adhesives, phenol formaldehyde (PF) and melamine urea formaldehyde (MUF), on the mechanical and fire properties of flame-retardant laminated bamboo lumber (LBL). The results demonstrated that the flame-retardant treatment using phosphorus–nitrogen–boron compounds endowed the LBL with excellent flame retardancy and smoke suppression properties, even though the bending strength and bond shear strength were slightly reduced. The PF-glued LBL exhibited superior mechanical and shear properties to the MUF-glued ones, primarily due to its higher processing temperature and deeper adhesive penetration. In addition, the MUF-glued flame-retardant LBL displayed better heat release reduction and smoke suppression properties than the PF-glued LBL, which resulted from the synergistic flame retardancy between the melamine element in MUF and the applied flame retardant. The analysis of the influence of adhesive type on the mechanical and fire properties of flame-retardant LBL holds significant importance for the future design and production of high-performance LBL material.
