利用钛酸酯偶联剂NDZ201、低温等离子体对亚微米Al2O3进行表面改性,改性后的粒子以粉末形式加入稀释后的酚醛树脂中,通过超声振荡作用制备低粘度氧化铝/酚醛树脂粘胶剂。通过红外表征钛酸酯偶联剂和低温等离子体的改性效果。通过TEM分析粒子在酚醛树脂的分散效果。在万能实验机上测试了氧化铝/酚醛树脂粘胶剂的剪切强度。结果表明,钛酸酯偶联剂的改性效果好于低温等离子体,超声作用提高了粒子在树脂的分散性,亚微米Al2O3质量分数为5%时粘胶剂对金属的粘接强度最高。
The titanate coupling agent NDZ201 was used to modify the surface of submicron Al2O3 by low temperature plasma. The modified particles were added into the diluted phenolic resin in the form of powder. The low viscosity alumina / phenolic resin was prepared by ultrasonic vibration Glue. Characterization of titanate coupling agents and low temperature plasma modification by infrared. The dispersion effect of the particles on the phenolic resin was analyzed by TEM. The shear strength of the alumina / phenolic resin adhesive was tested on a universal testing machine. The results show that the modification effect of titanate coupling agent is better than that of low temperature plasma. Ultrasound can improve the dispersibility of the particles in the resin. When the content of Al2O3 is 5%, the adhesion strength of the adhesive to the metal is the highest.
