酚醛树脂胶粘剂研究进展

摘要

Phenolic resin adhesive had many advantages, such as excellent water resistance, heat resistance, weather resistance, high bonding strength and chemical stability, so it was used in many fields. But there were many shortcomings for PF resin, such as high curing temperature, long hot pressing time, easy penetration, formaldehyde emission, high cost of raw materials and non-renewable. This paper reviewed the fast curing and low free formaldehyde phenolic resin adhesive, melamine, urea, lignin and biomass tar modified phenolic resin adhesive, and other modified phenolic resin adhesives. And its existing problems and development prospect were analyzed and expected.%酚醛树脂胶粘剂具有优良的耐水性、耐热性、耐候性，粘接强度高及化学稳定性好等优点而被用于诸多领域。但是其还存在固化温度高、热压时间长、易透胶、有甲醛释放、原料成本高且不可再生等缺点。综述了快速固化和低游离甲醛含量酚醛胶粘剂，三聚氰胺、尿素、木质素、生物质焦油以及其他改性酚醛树脂胶粘剂，并对其存在问题和发展前景作了分析和展望。
