摘要
利用分子模拟技术分别对天然橡胶(NR)以及防老剂N3100中的组分A,B和C建立分子模型,研究3种组分在NR胶料中的溶解度和迁移性,分析防老剂N3100在胶料中的析出性,并将各组分按不同用量加入NR胶料中,观察胶料喷霜情况。结果表明:与防老剂3100相比,防老剂N3100各组分单独合成及比例可调整,其有效含量大;常温下NR胶料中组分A,B和C不喷霜,最大用量分别不超过0.25,0.5和2份。
The molecular models of NR and component A,B and C of the antioxidant N3100 were established by molecular simulation technology,the solubility and mobility of those three components in NR compound were studied,and the leachability of antioxidant N3100 in the compound was analyzed. Various amount of each component was added into NR compound and the blooming of the compound was recorded. The results showed that,compared with antioxidant 3100,each component of antioxidant N3100 could be synthesized separately and its proportion could be adjusted,and the effective content was high. The maximum amounts of component A,B and C in NR compound were 0. 25,0. 5 and 2 phr,respectively, without blooming at room temperature.
