The Use of Ionizing Irradiation to Prepare Adhesives Based on Rosin and Ethylene Vinyl Acetate Copolymer

Document Type : Original Article

Abstract

 ADHESIVES based on rosin, ethylene vinyl acetate copolymer (EVA) blend and polyethylene-wax (PE-wax) by using ionizing irradiation were prepared. Low density polyethylene-wax (LPDE-wax) was added to aromatic hydrocarbon rosin/ EVA blend in the molten state and the miscibility and adhesion properties of ternary blends as hot-melt adhesive were investigated. Factors affecting the preparation process such as concentration and mixing percentage of polyethylene wax on improving the mechanical, thermal and adhesion properties of the prepared adhesive were studied. Also, the prepared adhesive has been tested through a series of standard rules of measurements for instance; peel strength, surface hardness, tensile-strength, elongation at break, thermal melting and scanning electron microscopy. The results showed that the increase of PE-wax added to the rosin/ EVA blend resulted in an increase in peel strength. The possibility of applications of the prepared adhesive in the field of automotive as adhesives for rubber to steel and rubber to rubber materials was suggested and applied.
