摘要
通过化学镀的方法在ABS树脂(丙烯腈-苯乙烯-丁二烯共聚物)表面形成一定含P量的Ni-P合金镀膜,研究强酸对该镀膜的腐蚀作用,以及强酸浓度、腐蚀温度、腐蚀时间对腐蚀后镀膜的可见光反射率的影响,得到了制备低光反射率腐蚀镀膜的工艺条件.结果表明:腐蚀后的镀膜在可见光范围内的反射率可以达到0.5%以下,实现了超黑的表面效果;同时,腐蚀后的镀膜对紫外、红外区域的电磁波也有较低的反射率;经过化学腐蚀,镀膜表面的元素质量分数发生变化,其中Ni元素的质量分数降低,P元素和O元素的质量分数增大;扫描电子显微镜(SEM)实验表明经过化学腐蚀,在镀膜表面产生了纳米尺度的微隙结构,这种表面形貌特征使腐蚀层具有了超黑的颜色效果.
Ni - P coating was formed on the ABS resin by chemical plating. The corrosive effect of acid was investigated and the influence of concentration of acid, corrosive time and corrosive temperature on the coating's reflectivity to visible light was measured. Furthermore, the condition of preparing low reflectivity coating was obtained. The results showed that corrosive treatment could change the weight percentage of elements of Ni - P coating, the weight percentage of Ni decreased while P and O increased. The reflectivity of corroded Ni- P coating to visible light was lower than 0. 5% and coating obtained the ultra black effects. Further SEM research illustrated that the surface of corroded Ni - P coating forms micro gap in nano scale which resulted in its ultra black effects.
