摘要
通过对稻壳粉/高密度聚乙烯复合材料热氧老化研究,得到材料的抗弯强度随老化时间的变化规律。稻壳粉/高密度聚乙烯复合材料在65℃热氧老化条件下,0~12 h期间抗弯强度急剧下降;12~122 h期间抗弯强度呈上升趋势;122 h后抗弯强度趋于稳定。
Through the study on the thermo-oxidative aging of rice husk powder/HDPF composites, the law that the bending strength changes with aging time is obtained. Under 65℃ thermo-oxidative conditions, the bending strength of rice husk powder/HDPF composites drops sharply within 0 - 12 h, shows an upward trend within the range of 12 - 122 h and tends to be stable after 122 h.
