Abstract

The poor bonding performance between aqueous adhesives represented by melamine-urea formaldehyde (MUF) resins and reed straw hinders their applications in the field of non-wood-based panels. Multi-hydroxyl polymers are highly reactive and are often used as crosslinkers. This study fabricated a resin with a strengthened cross-linked structure by combining a multi-hydroxyl polymer and MUF resin prepolymer. The reed particleboard was prepared by using this resin as an adhesive and reed stalk as the matrix. The results show that neighboring molecules combined to form C–O–C bonds that strengthened the cross-linked structure of the resin. In addition, the viscosity of the resin was increased, and a continuous adhesive layer on the surface of reed particles was formed, which slowed the penetration of reed particles. The adhesive layer significantly improved the mechanical properties of the reed particleboard. The maximum modulus of rupture (MOR), modulus of elasticity (MOE), and internal bonding strength (IB) of the reed particleboard were 33.53, 4126, and 0.79 MPa, respectively. The IB of the board was 3.3 times higher than that of the reed particleboard prepared with a conventional MUF resin. Reed straw is a non-wood biomass material that has the advantage of sustainable development and may replace wood-based materials to produce particleboard. This resin-prepared reed particleboard is expected to be used in areas such as custom furniture and engineering materials.
