摘要
用自制增韧母料(E-TMB)与高密度聚乙烯(PE-HD)热机械共混制得PE-HD/E-TMB共混物,研究了E-TMB中基体树脂和丁苯弹性体质量比(H/E)对共混物力学性能、熔体流动速率(MFR)和热稳定性能的影响。结果表明,当PE-HD/E-TMB共混物中丁苯弹性体的质量分数为6.3%时,E-TMB使PE-HD在保持优良刚性的同时,韧性大幅度提高。E-TMB中H/E的不同对共混物力学性能的影响不大;共混物的MFR随E-TMB中H/E的减小而逐渐增大;共混物的热分解温度均比纯PE-HD高11.4℃以上,且随E-TMB中H/E的减小而逐渐增大。
PE-HD/E-TMB blends was prepared using self-made toughening master batch E-TMB and PE-HD by means of thermal mechanical blending, and the effects of the ratio of matrix resin to elastomer（H/E） in E-TBM on the mechanical properties, MFR and the thermal stability of PE-HD/E-TMB were investigated. The results showed that when the elastomer content of PE-HD/E- TMB was 6.3% , the E-TMB made the toughness of PE-HD/E-TMB much higher than that of the pure PE-HD while the rigidity of PE- HD/E-TMB was also kept excellent. The influence of different I-L/E value on the mechanical properties of PE-HD/E-TMB was little. The MFR of the blends increased with the decrease of H/E value. The temperature of the thermal degradation of PE-HD/E-TMB was improved above 11.4℃ than that of pure PE-HD, and increased with the decrease of H/E value.
