摘要
为了提高微细铜粉的抗空气氧化性能,通过直流电弧等离子法制备超细铜粉,使用超声分散实现铜粉表面均匀包覆一层有机物,研究不同抗氧化剂表面改性工艺对铜粉抗氧化性能的影响。通过扫描电镜(SEM)、傅里叶红外光谱仪(FTIR)、X-射线衍射(XRD)和电子天平称重对包覆效果进行表征。研究结果表明:直流电弧等离子法制备球形超细铜粉分散在无水乙醇介质中,推荐较好的纳米铜粉表面抗氧化工艺为:30%苯并三氮唑(BTA)/30%柠檬酸(CA)复合表面活性剂包覆铜粉,超声20 min可有效阻碍铜粉在空气中的氧化。
In order to improve air oxidation resistance of fine copper powders,ultra-fine copper powders were prepared by a DC arc plasma method and their surface were evenly coated with organic materials via ultrasonic dispersion.Different antioxidants were used to increase the anti-oxidation capability and their surface modification processes were studied.The coated samples were characterized by scanning electron microscopy(SEM),Fourier infrared spectroscopy(FTIR),X-ray diffraction(XRD)and weighting.The result shows that the spherical ultra-fine copper powders can be dispersed in ethanol.The optimized anti-oxidation process is:BTA/CA(30%BTA,30%CA)as the coating material and ultrasonication for20min.
