摘要:

通过低温等离子体表面处理对丙烯腈?丁二烯?苯乙烯(ABS)表面进行刻蚀;以乙烯基三甲氧基硅烷、γ?巯丙基三甲氧基硅烷、γ?氨丙基三乙氧基硅烷为主体的无钯敏化、活化液对ABS进行表面镀镍,通过傅里叶变换全反射红外光谱(ATR?FTIR)、接触角测量仪和扫描电子显微镜(SEM)等探究了电镀ABS的性能,并根据GB/T 9286—2021,用90 °黏合强度测试法测试塑料与金属层之间的黏附牢固程度。结果表明,当处理时间为300 s、功率为600 W时,ABS电镀预处理效果最佳,此时结合强度达到0.94 kN/m。

Abstract:

The surface of acrylonitrile?butadiene?styrene (ABS) resin was etched through non?thermal plasma surface treatment. A palladium?free sensitization and activation solution composed of vinyltrimethoxysilane, (3?mercaptopropyl)trimethoxysilane, and 3?triethoxysilyl?1?propanamine was used for the surface nickel plating of ABS. The properties of electroplated ABS were investigated using Fourier?transform total reflectance infrared spectroscopy, contact angle measuring instrument, and scanning electron microscope. A 90° adhesive strength testing method was adopted to measure the adhesion between the plastic and metal layer according to the national standard GB/T 9286—2021. The results indicated that the optimal pretreatment effectiveness was achieved for ABS electroplating at a treatment time of 300 s and a power of 600 W. As a result, the substrate bonding strength reached 0.94 kN/m.

Key words: non?thermal plasma, palladium?free activation, electroplating, pretreatment
