폴리 (에틸렌-co-비닐 아세테이트)/고밀도 폴리에틸렌/수산화 알루미늄 복합재료의 기재 수지 함량 및전자빔 조사 조건에 따른 물성 변화 = Changes in Properties of Poly(ethylene-co-vinyl acetate)/High Density Polyethylene/Aluminum Hydroxide Composites According to the Matrix Resin Contents and Electron Beam Irradiation Conditions

다국어 초록 (Multilingual Abstract)

I n this study, changes in properties of poly(ethylene-co-vinyl acetate)/high-densitypolyethylene/aluminum hydroxide (EVA/HDPE/ATH) composites according to the matrix resin contentsand electron beam irradiation conditions were investigated. EVA/HDPE/ATH composites with variousHDPE contents were prepared by melt mixing and then irradiated with electron beams under variousconditions. The tensile strength of the composites was not significantly changed with increasing HDPEcontents, while the elongation-at-break of the composites was reduced due to the brittle nature of theHDPE. The gel contents, tensile strengths, and limiting oxygen index values of the composites were foundto increase with an increasing absorbed dose due to the formation of crosslinked network structures.
These results indicate that the electron beam irradiation is an effective method to improve the thermalstability, tensile strength, and flame retardancy of the composites.
