Beschreibung
Zusammenfassung:	The invention discloses a PBAT-PLA-based biodegradable hot-melt adhesive and a preparation method and application thereof.The PBAT-PLA-based biodegradable hot-melt adhesive is prepared from waste PBAT biodegradable plastic as a raw material, PBAT is separated out through elution, PLA is obtained through ring-opening polymerization reaction of lactide, finally, the PBAT and the PLA are subjected to transesterification, and the PBAT-PLA-based biodegradable hot-melt adhesive is obtained. The adopted raw material is waste biodegradable plastic, so that high-value conversion and utilization of waste are realized, and green low-carbon cycle development is promoted. The prepared PBAT-PLA-based biodegradable hot melt adhesive has complete biodegradability, a degradation product is free of secondary pollution, and the biodegradable hot melt adhesive has excellent bonding strength with metal and glass. The PBAT-PLA-based biodegradable hot melt adhesive is simple in preparation method and suitable for industrial product
