The invention discloses a prime coat-free polycarbonate composition with good appearance as well as a preparation method and application of the prime coat-free polycarbonate composition. The polycarbonate composition comprises the following components in parts by weight: 60-80 parts of polycarbonate, 15-30 parts of high-flowability resin, 2-8 parts of an interface enhancing modifier, 1-6 parts of a toughening agent, 0.1-0.3 part of an antioxidant and 0.3-0.5 part of a lubricant. And the high-flow resin is any one or two of ultra-low-viscosity polyethylene glycol terephthalate or polybutylene terephthalate. And the interface enhancement modifier is a styrene-acrylonitrile-amino methacrylamide terpolymer with an active amino group. According to the polycarbonate composition, the glossiness, the pinhole number and the PVD aluminum plating effect of a material are obviously improved, meanwhile, the notch impact strength and the melt flow rate of the material are enhanced to different degrees, and the polycarbonate composition can be widely applied to the field of prime-coat-free PVD film plating decoration parts.
本发明公开了一种免底涂的良外观聚碳酸酯组合物及其制备方法和应用。所述聚碳酸酯组合物包括如下组分:聚碳酸酯60~80重量份,高流动树脂15~30重量份,界面增强改性剂2~8重量份,增韧剂1~6重量份,抗氧剂0.1~0.3重量份,润滑剂0.3~0.5重量份。高流动树脂为超低粘聚对苯二甲酸乙二醇酯或聚对苯二甲酸丁二醇酯中的任意一种或两种。界面增强改性剂为带有活性氨基的苯乙烯‑丙烯腈‑氨基甲基丙烯酰胺三元共聚物。本发明的聚碳酸酯组合物明显改善材料的光泽度、针孔数量和PVD镀铝效果,同时材料的缺口冲击强度和熔体流动速率都有不同程度的增强,可广泛应用于免底涂PVD镀膜装饰件领域。
