高延龙,赵阳.Al3+改性骨胶的性能及其胶接工艺[J].河南化工,2023,40(2):26-28.Al3+改性骨胶的性能及其胶接工艺高延龙,赵阳∗(西京学院电子信息学院,陕西西安710123)摘要:用NaOH对骨胶进行降解,然后用Al3+对其进行配位改性,制得室温下呈液态的骨胶,探讨了改性机制。对骨胶改性前后的结构和性能进行表征和测试,并优选出改性骨胶压制胶合板的最佳工艺参数。结果表明:Al3+与N、O以配位键结合,形成稳定的五元环结构;骨胶经改性后,胶膜表面更为规整,没有明显缺陷,断裂面整体呈现海藻状结构,热稳定性无明显变化,耐水性明显提高。当热压的温度为110℃,时间为20min,压力为4MPa,存放时间为48h时,胶合板具有相对最大的胶接强度。关键词:骨胶;Al3+;改性;机制中图分类号:TQ431.5文献标识码:A文章编号:1003-3467(2023)02-0026-03PropertiesandBondingProcessofAl3+ModifiedBoneGlueGAOYanlong,ZHAOYang∗(SchoolofElectronicInformation,XijingUniversity,Xi′an710123,China)Abstract:Theboneglueisdegradedbysodiumhydroxide,thenmodifiedbyAl3+throughcoordination,liquidboneglueatroomtemperatureisobtained.Themodificationmechanismisanalyzed.Thestructuresandpropertiesofunmodifiedandmodifiedbonegluesarecharacterized.Theoptimumprocessparametersofmodifiedbonegluepressingplywoodareoptimized.TheresultsshowthatAl3+iscoordinatedwithNandOtoformastablefive-memberedringstructure.Afterthemodificationofboneglue,thesurfaceofthefilmismoreregularandthere...
