초록
In this study, effect of electron beam irradiation on the mechanical, thermal, andflammability properties of poly (ethylene-co-vinyl acetate)/high-density polyethylene (EVA/HDPE)blends containing magnesium hydroxide (MDH) as a flame retardant was investigated. The gelcontent increased with an increasing absorbed dose due to the formation of crosslinked newtorkstructures. Although the flame retardancy of the blends improved with increasing the content ofMDH, the mechanical properties of the blends deteriorated significantly. However, the mechanicalproperty, thermal stability, and flame retardancy of the blends improved by electron beamirradiation due to the formation of crosslinked 3-dimensional network structures. These resultsindicate that electron beam irradiation is an effective method to improve the thermal stability,mechanical properties, and flame retardancy of polyolefin blends containing flame retardants.
