Journal of Materials Research and Technology, Journal Year: 2022, Volume and Issue: 21, P. 3909 - 3946

Published: Nov. 1, 2022

Over the last 50 years, use of wood adhesives in manufacturing wood-based panel goods has increased efficiency resources. Wood are becoming more popular as need for panels grows. By 2028, global market is expected to reach 21.8 billion dollars. Even though urea-formaldehyde (UF), phenol-formaldehyde (PF), melamine-formaldehyde (MF), phenol-resorcinol-formaldehyde (PRF), and resorcinol-formaldehyde (RF) resins excellent terms bonding performance, workability, quality, economy, they consist harmful or toxic chemical agents derived from fossil resources, which make their application severely limited. This review aims go through most significant 'green' high-performance panels, such lignin, tannin, protein, natural rubber, emulsion polymer isocyanate (EPI), 1C PUR polyurethane (for glue-laminated cross-laminated timber), PMDI particleboards, medium-density low-density fiberboards), carboxylic acid, vegetable oil. The physical mechanical characteristics bio-based adhesives, well development sustainable, greener, discussed this work. Original research papers articles among important sources since provide complete information on recent developments eco-friendly, adhesives.

Published: Dec. 21, 2023

The current debate on the sustainability of bio-based products questions environmental benefits replacing fossil- by bio-resources. Here, we analyze trade-offs 98 emerging materials compared to their fossil counterparts, reported in 130 studies. Although greenhouse gas life cycle emissions for are average 45% lower (-52 -37%; 95% confidence interval), found a large variation between individual with none them reaching net-zero emissions. Grouped product categories, reductions ranged from 19% 35%) bioadhesives 73% (-84 -54%) biorefinery products. In terms other impacts, evidence an increase eutrophication (369%; 163 737%), indicating that should not be overlooked. Our findings imply evaluated basis and more radical developments required reach climate-neutral targets.

Fully Biobased Soy Protein Adhesives with Integrated High-Strength, Waterproof, Mildew-Resistant, and Flame-Retardant Properties

ACS Sustainable Chemistry & Engineering, Journal Year: 2022, Volume and Issue: 10(20), P. 6675 - 6686

Published: May 9, 2022

The low comprehensive properties of soy protein-based wood adhesives (SPWAs), such as weak bonding strength, poor water and mildew resistance, etc., are the main issues that severely restrict their wide application in manufacturing industry. In this study, fully biobased SPWAs with excellent flame retardancy were developed via a facile cross-linking reaction between protein isolate (SPI), furfuryl alcohol (FA), phytic acid (PA). Because SPI, FA, PA all derived from green sustainable biomass resources, components kind achieved 100% content. Response surface methodology (RSM) was utilized to optimize preparation SPWAs, predicted values highly consistent experimental results. optimized SPWA pH 4.0 content FA addition 16.7% exhibited high aged wet shear strengths 1.07 1.47 MPa, respectively, which superior those for other reported adhesives. Meanwhile, also displayed thermal stability, because dense multiple chemical/physical network P/N Therefore, work provides effective strategy development multifunctional high-performance
