中文摘要:
      研究不同种类短纤维(长度)对三元乙丙橡胶(EPDM)复合材性能的影响。结果表明:芳纶短纤维(简称AF)(9 mm)/玄武岩短纤维(简称BSF)(9 mm)并用比为1/1的复合材料的门尼粘度较小,DIN磨耗量最小(113.51 mm3),耐烧蚀性能最佳;沉淀法白炭黑与气相法白炭黑的复合材料的基本性能和热稳定性相当;BSF的长度越大,复合材料的耐磨性能和耐烧蚀性能越佳;随着BSF长度的增大,复合材料的Payne效应呈减小趋势,与BSF(3 mm)的复合材料相比,BSF(9 mm)的复合材料的Payne效应最小,BSF(9 mm)分散性最好;在热重分析中,700 ℃时复合材料的质量保持率由大到小依次为BSF(9 mm)/AF(9 mm)并用的复合材料、BSF(3 mm)的复合材料、AF(9 mm)的复合材料、AF(6 mm)的复合材料、AF(3 mm)的复合材料。
英文摘要:
      The effects of different types of short fiber(length) on the properties of ethylene-propylene-diene rubber(EPDM) composites were investigated.The results showed that,the composite using aramid short fiber (refered to as AF)(9 mm)/basalt short fiber (refered to as BSF)(9 mm) with a blending ratio of 1/1 had a smaller Mooney viscosity,the lowest DIN wear(113.51 mm3),and the best ablation resistance.The basic properties and thermal stability of the composite with precipitated silica were comparable to those of the composite with gas-phase silica.The greater the length of BSF was,the better the wear resistance and ablation resistance of the composite were.As the length of BSF increased,the Payne effect of the composite decreased.Compared with the BSF(3 mm) composite,the BSF(9 mm) composite had the smallest Payne effect,and the dispersibility of BSF(9 mm) was best .In TG analysis,at 700 ℃,the quality retention rate of the composite in descending order was the BSF(9 mm)/AF(9 mm) blend composite,BSF(3 mm) composite,AF(9 mm) composite,AF(6 mm) composite,AF(3 mm) composite.
