摘要

采用两步法合成了三油酸改性酚醛树脂。首先在酸性环境下，通过苯酚与三油酸的亲电加成反应制备改性树脂，然后与甲醛反应。与纯酚醛树脂相比，改性酚醛树脂的冲击强度提高了19~71%。改性酚醛树脂的最大断裂伸长率比纯酚醛树脂高约271%。通过引入亚甲基、酯键和脂肪长链的三油酸处理，改性酚醛树脂的韧性大大提高。热性能方面，三油酸的加入提高了改性酚醛树脂a的Tg，在酚醛树脂中引入三油酸也显著提高了酚醛树脂的粘度。本发明的制备方法简单易行，可扩大酚醛树脂在胶粘剂生产中的应用。

Study on improving toughness of phenolic resin via introducing triolein during synthesis

ABSTRACT Phenolic resin modified by triolein was synthesized by a two-step process. First, the modified resin was prepared by electrophilic addition reaction of phenol with triolein in acidic environment, then reacted with formaldehyde. The impact strength of modified phenolic resin increased by19~71% compared to that of pure phenolic resin. The maximum elongation at break of modified phenolic resin was higher by about 271% than that of pure phenolic resin. Toughness of modified phenolic resin was greatly improved through triolein treatment by bringing in the methylene, ester bond and aliphatic long chains. In terms of thermal properties, the addition of triolein has increased Tg of the modified phenolic resin a. The viscosity of phenolic resin also increased significantly by introducing triolein into phenolic resin. The preparation method developed here is simple and easy, which can expand the application of phenolic resin in adhesive production.

期刊介绍： Materials Research Innovations covers all areas of materials research with a particular interest in synthesis, processing, and properties from the nanoscale to the microscale to the bulk. Coverage includes all classes of material – ceramics, metals, and polymers; semiconductors and other functional materials; organic and inorganic materials – alone or in combination as composites. Innovation in composition and processing to impart special properties to bulk materials and coatings, and for innovative applications in technology, represents a strong focus. The journal attempts to balance enduring themes of science and engineering with the innovation provided by such areas of research activity.
