As the environmental pollution caused by the indiscriminate use and disposal of non-degradable plastics has become an internationally-surged problem, the urging needs of biodegradable materialsalso arise in the adhesive field. In particular, Hot melt adhesives have been widely used in the adhesive field due to their eco-friendly, fast curing speed, and prompt adhesion characteristic advantages. However, the main materials for hot melt adhesives used in packaging areaare comprised of poly(ethylene vinyl acetate) (EVA) and poly olefin (PO), which are not biodegradable; hence they ultimately accrete the environmental burden. In this study, PBS hot-melt adhesives was prepared by melt compounding of a PBS with gum rosin, dehydrogenated rosin, and dehyrogenated rosin ester. The adhesive strength of was confirmed through the peel test. The causes of the adhesion were analyzed in terms of rheological, surface properties, and crystallization behavior. |
