摘要
首先分析了聚碳酸酯工程塑料表面无铬微蚀的研究现状,并归纳了几种不同微蚀方法对聚碳酸酯基板的处理效果,重点介绍了一种环境友好的二氧化锰-硫酸微蚀体系。经过该体系的微蚀处理,聚碳酸酯表面形成了大量孔径均匀且深度适中的微孔,表面粗糙度增大,同时基板表面由憎水性变为强的亲水性,高表面粗糙度与强亲水性的共同作用将基板与镀层间的粘结强度提高到1.10 k N/m。
Researching situation of surface micro-etching for polycarbonate （PC） engineering plastics with chromium-free pretreatment was reviewed firstly,and the treatment effects of several different micro-etching methods on the surface of PC plastics were summarized. Then,MnO2-H2SO4 system which was an environ- ment-friendly surface micro-etching system was introduced as a key point. After micro-etched by the micro- etching system, many uniform micropores were formed on the PC substrate surface. Results indicated that surface roughness was increased,and substrates surface had been changed from hydrophobic to hydrophilic after the PC substrates were micro-etched in the aforementioned system. Adhesion strength was improved to 1.10 kN/m by the combined effects of higher surface roughness and stronger surface hydrophilia.
