将传统交联(使用过氧化物)和辐射处理结合到一起,具有现实意义。通过描述辐射/过氧化物及过氧化物/辐射交联热塑性弹性体Engage 8200的现象,并与分别单独采用过氧化物交联和辐射交联的过程进行了对比,发现化学交联和辐射交联的结合,可以显著影响弹性体的交联效率和氧化降解。弹性体中添加芳香族过氧化物可对交联和后辐射氧化现象起到防护作用。
It is of practical significance to combine traditional cross-linking (using peroxides) with radiation treatment. By describing the phenomena of radiation / peroxide and peroxide / radiation crosslinking of the thermoplastic elastomer Engage 8200 and the comparison with the processes of crosslinking with peroxide and radiation crosslinking alone, respectively, it was found that chemical crosslinking and radiation crosslinking The combined combination can significantly affect the crosslinking efficiency and oxidative degradation of the elastomer. The addition of aromatic peroxides to elastomers can provide protection against crosslinking and post-oxidation phenomena.
