【摘要】 介绍烷基酚醛增粘树脂的合成工艺、改性方法和作用机理。烷基酚醛增粘树脂由于酚环上有一定支化度且柔顺性好的取代烷烃基团,与橡胶分子具有良好的相容性,酚羟基具有一定的极性,彼此之间能形成氢键,混炼过程中在胶料界面上形成互穿氢键网络结构,使粘合材料达到均一充分的融合。通过改性可进一步提高烷基酚醛增粘树脂的极性,从而提高其增粘效果。更多还原

【Abstract】 The synthesis process,modification method and action mechanism of alkyl phenolic tackifying resin were introduced.Alkyl phenolic tackifying resin had good compatibility with rubber molecules due to the substitution of alkane groups with certain branching degree and good flexibility on the phenolic ring.Moreover,the phenolic hydroxyl groups had a certain polarity and could form hydrogen bonds with each other;therefore,during the mixing process,an interpenetrating hydrogen bond network structure was formed on the rubber interface,which made the adhesive materials more uniform.The modification further increased the polarity of the alkyl phenolic tackifying resin,thereby improving its tackifying effect.更多还原
