Abstract

The EPDM (ethylene-propylene-diene monomer) hybrids with improved thermal and radiation strengths containing 1 and 5 phr of polyhedral oligomeric silsesquioxane (vinyl-POSS, Ov-POSS) and/or 2 phr of microalgae ( () and ()) powders were investigated in respect to their thermal stability after γ-irradiation. The material durability under accelerated degradation was qualified by chemiluminescence and gelation, which prove the contribution of inorganic filler and microalgae extracts on the increase of hybrid thermal stability, as well as the interaction between added components (POSS and or ). The activation energies and the durabilities under accelerated degradation were calculated, indicating their suitable usage as appropriate materials in various applications. The reported results indicate the improvement effect of both microalgal powders on the oxidation strength, but the contribution of grabs attention on its efficient effects upon the prevention of degradation under accelerated aging conditions. The thermal performances of the tested EPDM based hybrids are remarkably ameliorated, if the certain formulation includes Ov-POSS (5 phr) and (2 phr), certifying its suitability for the pertinent applications.

摘要

研究了含有1份和5份多面体低聚倍半硅氧烷（乙烯基-POSS、八乙烯基-POSS）和/或2份微藻（（）和（））粉末的具有改善的热强度和辐射强度的三元乙丙橡胶（EPDM）共混物在γ辐照后的热稳定性。通过化学发光和凝胶化来评估加速降解条件下的材料耐久性，这证明了无机填料和微藻提取物对共混物热稳定性提高的贡献，以及添加成分（POSS和或）之间的相互作用。计算了活化能和加速降解条件下的耐久性，表明它们适合作为各种应用中的合适材料。报道的结果表明两种微藻粉末对氧化强度都有改善作用，但（）在加速老化条件下对防止降解的有效作用值得关注。如果特定配方包含八乙烯基-POSS（5份）和（2份），则测试的基于EPDM的共混物的热性能会显著改善，证明其适用于相关应用。
