腰果酚改性酚醛树脂的研究进展

Research progress of cardanol modified phenolic resin

随着现代社会的快速发展,对酚醛树脂的韧性、耐热性、耐水性等方面有了更高的要求,以腰果酚部分替代苯酚后合成腰果酚改性的酚醛树脂,不仅能够提高其韧性及耐热性,还能大大降低生成产成本,绿色环保。因此,腰果酚用作酚醛树脂的生物质改性剂具有较强的应用价值。介绍了腰果酚的结构与性质,简述了腰果酚改性酚醛树脂的制备方法、改性方法,及其在摩擦材料、模塑料、酚醛泡沫、涂料、复合材料等领域的应用。

With the rapid development of modern society,the industry has higher requirements for the toughness,heat resistance and water resistance of phenolic resin.The cardanol modified phenolic resin after partially replacing phenol with cardanol can not only improve its toughness and heat resistance,but also greatly reduce the production cost,making it environmentally friendly.Therefore,cardanol has strong application value as a biomass modifier of phenolic resin.The structure and properties of cardanol were introduced.The preparation and modification methods of cardanol modified phenolic resin,and its application in the fields of friction materials,molding compounds,phenolic foam,coatings and composite materials were briefly described.
