合成了一种新型高耐热酚醛树脂,并对其结构和性能进行了分析。研究发现,这种高耐热酚醛树脂对金属有良好的粘接性能,通过增韧改性可以进一步提高粘接强度;通过TG/DTA热分析手段,对合成过程中催化剂的加入量进行定量研究发现,当催化剂为树脂质量的12.5%时,合成树脂的耐热性能达到最佳,其粘接性能也非常优良。而且,用红外吸收光谱对这种新型高耐热酚醛树脂进行了表征,并确定了树脂的基本结构。 A new type of high heat phenolic resin was synthesized and its structure and properties were analyzed. The results show that the high heat-resisting phenolic resin has a good adhesion to metal, and the adhesion strength can be further improved by toughening modification. The amount of catalyst added during the synthesis process is quantitatively determined by means of TG / DTA thermal analysis It was found that when the catalyst is 12.5% ​​of the mass of the resin, the heat resistance of the synthetic resin is optimized and its adhesive property is also excellent. Furthermore, the new high heat resistant phenolic resin was characterized by infrared absorption spectroscopy and the basic structure of the resin was determined.
