聚碳酸酯材料广泛应用在光盘制造业中。为了提高光盘级聚碳酸酯的耐老化性能,研究了两种表面覆盖层技术,即旋转涂覆薄膜技术和磁控溅射镀膜技术,通过调整试验参数,找到最佳的试验方案,分别在聚碳酸酯表面制备出紫外光固化保护膜和SiO2保护膜,所制备的两种保护膜表观良好,平滑、致密、有较高的环境适应性能力。覆盖保护膜后的光盘仍能够正常读写和存储信息。 Polycarbonate materials are widely used in optical disc manufacturing. In order to improve the aging resistance of the disc-grade polycarbonate, two kinds of surface coating technology, namely spin-coated film technology and magnetron sputtering film technology, were studied. By adjusting the test parameters, the best experimental program was found, The UV-curing protective film and the SiO2 protective film were prepared on the surface of the carbonate. The two prepared protective films showed good appearance, smoothness, compactness and high environmental adaptability. The optical disk covering the protective film can still read and write information normally and store it.
