葡萄糖基生物质树脂的优化制备及其改性杨木性能
Optimization of glucose-based bio-resin preparation and performance of modified poplar wood
摘要
Abstract
The sustainability and safety of wood modification have gained increased attention due to the growing environmental and resource challenges.Traditionally,wood modification technologies have relied on fossil resources as raw materials,which are energy-intensive,highly polluting,and non-degradable.Therefore,it is essential to explore efficient,low-energy,green wood modification technologies.Using biomass resources for wood modification,biomass-based wood modifiers can enhance wood properties,reduce dependency on fossil resources,and improve the degradability of wood materials.This approach presents a unique opportunity for advancing sustainable wood modification.In this study,environmentally friendly biomass resin was developed to impregnate and treat soft wood from plantation forests using glucose instead of formaldehyde as a catalyst.By investigating the yield of glucose conversion to 5-hydroxymethylfurfural(HMF)under the different compound acids such as CuSO4/NH4 Cl,AlCl3/H3 PO4,H3 PO4/Al2 O3,and AlCl3/HCl,the compound acids with the highest conversion were selected to prepare three glucose-based bio-resins respectively,i.e.melamine-urea-glucose(MUG),glucose-polyacrylamide(GP)and MUG/GP blended resins.The properties of the different bio-resin solutions and their modified wood samples were tested and analyzed.The results showed that:the catalytic effect of AlCl3/HCl was the best,and the yield of HMF was 16.5 times that of CuSO4/NH4 Cl,because AlCl3 can promote the isomerization of glucose,and HCl can effectively catalyze the rapid dehydration of fructose.All three resins had high solid content,low viscosity and good water solubility,and all had characteristic absorption peaks of amino resin such as imino group.The storage life of MUG/GP resin was short,GP resin had the lowest solid content and the highest viscosity.In contrast,MUG resin exhibited the highest solid content,the lowest viscosity,stable storage,low cost,and near-neutral pH,making it the selected resin.All three resins can effectively reduce the water absorption and swelling rate of poplar wood and improve its anti-swelling rate.The water absorption,swelling rate and anti-swelling rate of MUG modified wood were 50.96%,3.57%and 75.85%respectively,indicating excellent dimensional stability.MUG resin is a biomass-based green modifier for wood with excellent performance,stable storage and low cost,which has tremendous potential for application.关键词
