羟基丙烯酸树脂改性水溶性醇酸树脂研究 Title:ResearchontheModificationofHydroxyl-FunctionalAcrylicResinwithaWater-SolubleAlcoholAcidResin Abstract: Hydroxyl-functionalacrylicresinsarewidelyusedinvariousapplicationsduetotheirexcellentfilm-formingpropertiesandchemicalresistance.However,theirwatersolubilitylimitstheirpotentialincertainindustries.Inthisstudy,weaimedtoovercomethislimitationbymodifyinghydroxyl-functionalacrylicresinswithawater-solublealcoholacidresin.Themodifiedresin'sproperties,suchaswatersolubility,film-formingability,andchemicalresistance,werecharacterizedandcomparedwiththeunmodifiedresin. Introduction: Hydroxyl-functionalacrylicresinshavegainedsignificantattentioninmanyindustries,includingcoatings,adhesives,andprintinginks,duetotheirexcellentfilm-formingpropertiesandthermalstability.However,theirlimitedwatersolubilityhasbeenachallengeincertainapplications. Inrecentyears,modifyinghydroxyl-functionalacrylicresinswithwater-solubleresinshasemergedasapotentialsolution.Byblendingthesetworesins,wecancombinetheexcellentfilm-formingpropertiesofhydroxyl-functionalacrylicresinswiththewatersolubilityofalcoholacidresins.Thismodificationstrategyopensupnewpossibilitiesfortheapplicationofhydroxyl-functionalacrylicresinsinwater-basedsystems. ExperimentalMethodology: 1.SynthesisofHydroxyl-FunctionalAcrylicResin:Hydroxyl-functionalacrylicresinwassynthesizedusingaconventionalfree-radicalpolymerizationreaction.Thereactionmixturecomprisedofacrylicmonomers,hydroxyl-functionalmonomers,initiator,andsolvent.Thereactionwascarriedoutundercontrolledconditionstoobtainahydroxyl-functionalacrylicresinwithdesiredproperties. 2.ModificationwithWater-SolubleAlcoholAcidResin:Thehydroxyl-functionalacrylicresinwasmodifiedbyblendingwithawater-solublealcoholacidresin.Differentblendingratioswereusedtostudytheeffectofthemodificationonthepropertiesoftheresin.Theblendingprocesswasconductedundercontrolledconditionstoensureahomogeneousmixture. 3.CharacterizationofModifiedResin: a.WaterSolubility:Thewatersolubilityoft
