Gluability of Thermally Modified Aspen, Birch, and Poplar Rotary Cut Veneers with Suberinic Acids Adhesive

Sustainability, Journal Year: 2025, Volume and Issue: 17(5), P. 1990 - 1990

The eco-friendly lifestyle has gained traction at individual and industrial levels, especially following Europe’s “Green Deal”. While the woodworking industry in Latvia made strides toward waste-free production, wood processing still produces by-products that require effective utilization. Instead of burning these residues for energy, a sustainable option is repurposing birch bark into suberinic acids adhesive, which environmentally friendly safe humans. Research shows thermally modified aspen, birch, poplar veneers treated using Termovuoto process 160 °C/50 min, 204 °C/120 214 217 °C/180 218 °C/30 min can be bonded with this adhesive meet EN 314-2:1993 standard outdoor applications classified as Class 3 bonding. However, hydrothermally °C 50 do not bond successfully, failing to requirements.

Developing Eco-Friendly, High-Performance Soy Protein Plywood Adhesive via Core–Shell Hybridization and Borate Chemistry

Materials, Journal Year: 2025, Volume and Issue: 18(5), P. 1144 - 1144

Published: March 4, 2025

Developing eco-friendly, high-performance adhesives is crucial for sustainable industrial applications but remains a significant challenge. Herein, synergistic strategy combining core-shell hybridization and borate chemistry was employed to fabricate multifunctional soy protein (SPI) adhesive with excellent adhesion. Specifically, reactive hybrid (POSS-U) synthesized via free-radical polymerization using octavinyl-POSS as the core urushiol (U) shell. Sodium (SB) then added crosslinker, along POSS-U SPI, prepare SPI/POSS-U/SB adhesive. The exhibited 100% increase in dry shear strength (2.46 MPa) wet of 0.74 MPa, meeting indoor application standards. Due thermal shielding char formation POSS SB, peak heat release rate modified reduced by 25.4%, revealing flame retardancy. Additionally, remained mold-free 144 h due antifungal properties boron. This work provides an innovative approach enhancing protein-based contributes advancement composite materials.
