| 摘 要： | 文章利用实验及IR图谱分析的方法,对硼酸-桐油双改性酚醛树脂的结构进行了表征,并对其反应机理进行了分析。结果表明,改性后树脂分子中生成高键能的B-O键及含硼的三向交联结构,可使树脂达到耐热性提高的目的;引入了桐油柔性链,桐油分子中部分双键打开,连接于苯环的邻位或对位处,从而使得刚性的硼酚醛树脂分子链段中嵌有柔性的烷基长链,形成网状结构,起到内增韧作用,使树脂的柔韧性得到改善。

| Abstract: | The reaction mechanism of phenolic resin binary modified by boric acid & tung oil was analyzed by the methods of experimental analysis and IR spectra analysis. The results indicated that the inorganic element boron constitutes B-O bond with high bond energy and three way cross-linked structure in resin, so the thermal resistance of rein is improved. The flexible chain molecular of tung oil enters into resin carbon skeleton structural through the resin modification. The partial double bond of tung oil is spl... |
