摘要:
为解决树脂表面金属化问题，金属化之前要对树脂进行一定程度的表面处理。采用湿法化学改性处理法对环氧树脂（ EP ）基材进行表面改性，利用场发射扫描电镜、原子力显微镜、视频光学接触角测量仪和 90° 剥离法，研究 EP 基材经过不同 Na 4 P 2 O 7 含量的 MnO 2 -H 2 SO 4 -H 2 O-Na 4 P 2 O 7 体系改性不同时间后 EP 基材的表面性能，获得合理的 EP 基材改性条件。结果表明：在改性温度为 60 ℃ ， V H2SO4 ∶ V H2O =3 ∶ 1 ， Na 4 P 2 O 7 含量为 30 g/L 的改性处理条件下，改性处理 20 min ， EP 基材表面出现大量的微小孔洞，孔的大小比较匀称，孔的深度适中，表面粗糙程度增大，表面亲水性能增强，这种凹凸不平和强亲水性能的表面，有利于化学镀过程中金属颗粒的沉积，提高镀膜的粘结性，最大粘结强度达到 7.35 N/cm ，改性效果比较理想。
Abstract:
： A certain degree of surface treatment on the resin was very important before metallization in order to solve the problem of metallization of resin surface. In this work ， the MnO 2 -H 2 SO 4 -H 2 O-Na 4 P 2 O 7 system was used as the surface modification system for epoxy resin substrate （ EP ） . Effects of the content of sodium pyrophosphate and surface modification time upon the surface morphology ， surface roughness ， and adhesion strength of epoxy resin substrate were studied ， by observing field emission scanning electron microscopy （ SEM ）， video optical contact angle measuring instrument ， and the 90-degree stripping measurement. The results showed that the hydrophilicity ， surface roughness and the adhesion strength of EP substrate were increased by a wide margin after the surface modification. And the reasonable modification condition was that the modification temperature was 60 ℃ ， V H2SO4 ∶ V H2O =3 ∶ 1 ， the sodium pyrophosphate content in the modification system was 30 g/L ， and the modification time was 20 minutes. In addition ， the adhesion strength between the epoxy resin substrate and copper plating reached 7.35 N/cm. Therefore ， the system of MnO 2 -H 2 SO 4 -H 2 O-Na 4 P 2 O 7 was a new environmentally friendly system for EP surface modification.
