摘要
酚醛树脂是一种传统的合成树脂,在诸多行业有着广泛的应用。提高酚醛树脂的耐热性一直是业内研究的热点。系统介绍了国内外提高酚醛树脂耐热性所采取的改性方法,以及所取得的研究成果。提出了今后酚醛树脂耐热改性的主要研究方向是进一步提高PF在400～700℃时的结构热稳定性,并开发出良好的改性剂组合、优化热处理工艺,使酚醛树脂分别在低、中、高温区均具有较稳定的结构与性能。
Phenol-formaldehyde resin（PF） is one of traditional synthetic polymer materials,which has been widely used in many fields.How to improve its heat resistance is always a hot spot.Thermal modifying methods as well as their modifying efficiency are introduced.At the same time,a proposal is put forward to developing a modifying combination.The combination can not only improve the stability of the structure and properties of PF at 400-700℃,but also stabilizes the one at low,middle and high temperature with a optimized heat-treated process.
