Abstract The use of glyoxal to replace formaldehyde for preparing wood adhesive was considered as an effective way address issue. However, the properties glyoxal-based resins via continent preparation process were poor, especially water resistance pretty low compared with formaldehyde-based resins. Here, a new glyoxal-polyvinylamine-urea (GPU) copolymer resin excellent presented in this work by using polyvinylamine(PVAm) modifier agent enhance performance based bonding strength and evaluated measuring mechanical property three-plywood produced our laboratory. structural features characterized FT-IR, ESI-MS, their curing thermal behavior also explored. This has fast rate good stability, best dry plywood 2.37MPa, wet 1.10MPa 0.71MPa after immersed cold 24h 63 ℃ hot 3h, respectively. enhanced can be explained formation better cured network verified from ESI-MS spectroscopy analyses.

Expanded polystyrene (EPS) particles are commonly used for thermal insulation in lightweight building materials due to their low density, conductivity, and affordability. However, shortcomings such as hydrophobicity poor fire safety limit the application of EPS. Bio-based flame retardants have been developed use polymer composites renewable, environmentally friendly, non-toxic properties. In this study, improve hydrophilicity resistance EPS particles, phytic acid (PA)/chitosan (CS)–polydopamine (PDA)@EPS (PA/CS-PDA@EPS) with a bio-based coating were prepared by using simple method based on PDA@EPS PDA an adhesive PA CS retardants. The results showed that modified had good hydrophilicity, residual carbon yield 10PA/3CS-PDA@EPS samples was increased 24 wt%, maximum loss rate reduced 69% compared unmodified flammability tests, also demonstrated spread some resistance. Furthermore, exhibited even after multiple washings. hydrophilic fire-resistant anticipated offer novel approach advancement EPS-based materials.

The demand for non-toxic, environmentally friendly, easily processable, water-resistant, flame-retardant and antimicrobial adhesives in the wood processing industry is becoming increasingly urgent. Few can possess these functions altogether while being synthesized easily. This paper presents a one-pot process utilizing corn starch, sodium hypochlorite, itaconic acid, borax to synthesize starch-based adhesive with dual crosslinking. Initial crosslinking takes place between carboxyl groups of acid hydroxyl on oxidized starch due formation ester bonds. Secondary by borate bonds occurs boric acid. entire reaction benign, generating no waste, all reactants converted into final products, aligning "green" chemistry principles. When used bond wooden boards, this achieved dry shear strength 5.34 ± 0.24 MPa, wet 1.22 0.06 MPa after soaking water. Additionally, exhibited antibacterial properties against Escherichia coli (ATCC 8739) Staphylococcus aureus. Moreover, incorporated, demonstrated flame-retardancy. limiting oxygen index bonded boards was 30.9 %, qualifying it as material. These multiple render promising applications industry.

Aqueous wood adhesives with both water retention and strong bonding strength are essential for industrial applications. However, the enhanced of adhesive often suffers from low resistance due to its increased hydrophilicity. Inspired by mechanical support in plant cell, we develop a multifunctional biomass soybean meal (SM) combining rigid internal boron-nitrogen coordinated boronic esters structure reinforcement flexible zwitterionic polymer retention. Such design provides good dry (2.03 MPa) wet shear (1.14 strengths demonstrates durable adhesion various harsh environments up 80 days. The exhibits anticipated property, extending plywood shaping manufacturing time 60 min ability water-retaining convert free into bound state suppress evaporation. Additionally, 10-fold increase mildew compared SM flame retardancy. This study presents versatile efficient approach developing durable, water-retaining, sustainable aqueous techniques materials.
