摘要

为了考察膨润体系中乙酰乙酸乙酯(EAA)浓度和膨润时间对聚碳酸酯-聚丙烯腈-丁二烯-苯乙烯共聚物(PC-ABS)膨润效果的影响，通过EAA-氮甲基吡咯烷酮(NMP)-水体系对PC-ABS基板进行膨润处理，然后在70℃下，以H₂SO₄-MnO₂-H₂O体系为微蚀体系，对PC-ABS基板微蚀20 min。结果表明，当膨润体系中EAA体积分数为50%,膨润温度为55℃时，膨润5 min后PC-ABS可以获得合适的膨润度。通过此条件膨润及微蚀处理后的PC-ABS基板表面形成了分布均匀且致密的孔洞，基板表面与水的接触角减小，基板表面的亲水性增强，后续化学镀铜层与PC-ABS基板间的粘接强度达到4.03 N/cm,获得了理想的膨润和微蚀效果。

Abstract

To investigate the effects of ethyl acetoacetate(EAA) concentration and swelling time on the swelling performance of polycarbonate-polyacrylonitrile-butadiene-styrene copolymer(PC-ABS) in swelling system, the PC-ABS substrates were subjected to swelling treatment using EAA-N-methyl-2-pyrrolidinone(NMP)-H₂O system. Subsequently, employing an H₂SO₄-MnO₂-H₂O system as the micro-etching system, the PC-ABS substrates were micro-etched for 20 min at 70 ℃. Results showed that when the volume fraction of EAA in the swelling system was 50% and the swelling temperature was 55 ℃, the PC-ABS could obtain appropriate swelling degree after 5 min of swelling. Following this condition, swelling and micro-etching treatments led to the formation of evenly distributed and dense pores on the surface of the PC-ABS substrates. The contact angle between the substrate surface and water decreased, enhancing the hydrophilicity of the substrate surface. Consequently, the adhesive strength between the subsequently electroless copper plating layer and the PC-ABS substrate reached 4.03 N/cm, achieving the desired swelling and micro-etching effects.
