摘要

利用Minitab软件设计实验，以超高分子量聚乙烯纤维(UHMWPE)为原料，研究了在不同的超临界CO

流体状态下，处理压力、温度和时间等因素对三羟甲基丙烷三甲基丙烯酸酯(TMPTMA)渗入率的影响，确定了最佳因素设置范围；通过单因子实验优化了超临界CO

处理工艺，并对经过电子束辐照的UHMWPE纤维凝胶含量和蠕变率进行了测试。研究结果表明：处理温度对TMPTMA的渗入率影响最大，其次为压力，时间的影响最小，确定了最优工艺条件为处理压力25MPa，温度80℃，时间30min；TMPTMA渗入率越高，电子束辐照后UHMWPE纤维的增感辐照交联效应和抗蠕变效果越好。

Abstract

With the ultra-high molecular weight polyethylene (UHMWPE) fibers as materials

the influence of processing pressure

temperature and time on the infiltration rate of trimethylolpropane trimethacrylate(TMPTMA) under the different supercritical carbon dioxide fluid state using Minitab software to design experiment were studied and the optimal set range of factors were determined ; The supercritical CO

process was optimized through the signal factor experiment

in addition

the gel content and creep rate of UHMWPE fibers after electron beam irradiation were tested. The results showed that the processing temperature had the most significant effect on the infiltration rate of TMPTMA

followed by pressure

time had the minimal effect. The optimal conditions were processing pressure 25Mpa

temperature 80℃

time 30min; The higher the infiltration rate of TMPTMA was

the better effects of sensitizing irradiation crosslinking and anti-creep of UHMWPE fibers after electron beam irradiation were.
