An environment-friendly wood adhesive using modified wheat gluten by isophorone diisocyanate

Properties of Bark Particleboard Bonded with Demethylated Lignin Adhesives Derived from <i>Leucaena leucocephala</i> Bark

“…Lignin adhesives are often chosen as a natural and eco-friendly alternative, while UF adhesives are commonly selected for their water-resistant properties [61]. Manufacturers make the appropriate adhesive choice based on the intended application and the performance requirements of the final product [62].…”

Recent progress of biomass in conventional wood adhesives: a review

“…In addition to soy protein, some other proteins can also be cross-linked with isocyanates to prepare wood adhesives with good properties. Liu et al 16 employed ethanol and isophorone diisocyanate (IPDI) as the primary chemical additives in order to create an innovative and eco-friendly approach for producing wood adhesives based on wheat gluten (WG) that exhibit excellent performance. WG was dissolved in ethanol, and then modified with IPDI cross-linking agent.…”

“…In addition, UF resin adhesive, melamine resin adhesive and PF resin adhesive are also known as “trialdehyde adhesive” because they all use formaldehyde as raw material. 16 The conventional production process for “trialdehyde adhesive” involves the release of formaldehyde gas, precipitating both environmental contamination and health hazards. Substituting biomass for the requisite formaldehyde in the production process, 17 or blending biomass with formaldehyde adhesives, 18 offers an avenue for diminishing formaldehyde emissions during application.…”

Wheat gluten proteins phosphorylated with sodium tripolyphosphate: Changes in structure to improve functional properties for expanding applications

“…This led to changes in the spatial structure of proteins and physicochemical properties that affect their applications ( He et al, 2019 ). Physical modifications to change the spatial structure and intermolecular aggregation of proteins was carried out by modest thermal denaturation, mechanical treatment, and ultrasounds ( Liu et al, 2021 ). However, physical modifications have high equipment demand, which is difficult to apply in large scale for industrial applications.…”
