Abstract

The effect of irradiation on a 90/10 ethylene vinyl acetate/waste tire dust (EVA/WTD) blend was studied in the presence of 4 phr trimethylolpropane triacrylate (TMPTA) or tripropyleneglycol diacrylate (TPGDA). The blend was irradiated using a 3.0-MeV electron beam machine at 0, 50, 100, 150, and 200 kGy irradiation doses. The properties studied include gel content, tensile properties, hardness, morphology, and dynamic mechanical properties. The result revealed that the increment in irradiation doses will increase the percentage of gel content. The gel content further increased with the introduction of TMPTA and TPGDA. This is attributed to the increase in crosslink density. Tensile properties of EVA/WTD blend increase with the introduction of irradiation except for elongation at break. The tensile-fractured surface of EVA/WTD blends showed ductile type of failure upon irradiation of the blends in the presence of crosslinking agent. One glass transition temperature obtained from dynamic mechanical analysis for 90/10 EVA/WTD blend after irradiation indicates that compatibility between EVA and WTD phases increased.

辐照交联醋酸乙烯/废轮胎粉尘共混物的性能研究

研究了在4phr三丙烯酸三甲基丙烷(TMPTA)或三丙烯酸三丙二醇(TPGDA)存在下，辐照对90/10乙烯醋酸乙烯/废轮胎粉尘(EVA/WTD)共混物的影响。用3.0 mev的电子束机分别以0、50、100、150和200 kGy的辐照剂量照射混合物。研究的性能包括凝胶含量、拉伸性能、硬度、形貌和动态力学性能。结果表明，辐照剂量的增加会增加凝胶含量的百分比。随着TMPTA和TPGDA的加入，凝胶含量进一步增加。这是由于交联密度的增加。随着辐照的引入，EVA/WTD共混物的拉伸性能除断裂伸长率外均有所提高。在交联剂的作用下，EVA/WTD共混物的拉伸断裂表面表现为延性破坏。通过对90/10 EVA/WTD共混物辐照后动态力学分析得出的一个玻璃化转变温度表明，EVA与WTD相的相容性增强。
