Title:ResearchontheSynthesisProcessofBioethanolLignin-PAEModifiedSoyProteinAdhesive
Abstract:
Inrecentyears,thedevelopmentofeco-friendlyandsustainableadhesiveshasgainedsignificantattentioninvariousindustries.Thisstudyaimstoinvestigatethesynthesisprocessofbioethanollignin-polyamidoamine-epichlorohydrin(PAE)modifiedsoyproteinadhesive.Theutilizationofligninandsoyproteinintheadhesivesynthesiscannotonlyreducethedependenceonfossil-basedmaterialsbutalsocontributetothevalorizationoflignocellulosicbiomass.Thispaperpresentsacomprehensiveanalysisoftheresearchanddevelopmentworkundertakentostudythesynthesisprocess,properties,andpotentialapplicationsofthelignin-PAEmodifiedsoyproteinadhesive.
