摘　　要：通过共混造粒的方法制备了丙烯腈-丁二烯-苯乙烯(ABS)、金属铝粉(含助剂)、硅酮粉、聚甲基丙烯酸甲酯(PMMA)等不同组合配方的高光亮耐划伤免喷ABS材料,采用高光无痕注塑工艺进一步提高其表面性能,并分析了光泽度、光亮度、铅笔硬度和摩擦系数。结果发现,通过添加大粒径(50μm以上)金属铝粉(含助剂)开发免喷ABS,并采用高光无痕注塑工艺可以有效提升表面高光亮效果,光泽度达到90以上,光亮度达到80以上,铅笔硬度F以上;通过添加硅酮粉使得ABS表面摩擦系数有一定下降,但添加比例需控制在1%左右,免喷ABS/PMMA合金料可以使得ABS表面硬度达到H以上;基于高光无痕注塑工艺的高光亮耐划伤免喷ABS在注塑包装上的应用是可行的。This article reports the preparation of various formulations of high gloss scratch resistant spray free acrylonitrile butadiene styrene(ABS)materials using blending granulation technology.The formulations include metal aluminum powder(containing additives),silicone powder,and polymethyl methacrylate(PMMA).The surface properties of the material were further optimized using a high gloss seamless injection molding process,and the glossiness,brightness,pencil hardness,and friction coefficient of the material were systematically analyzed.The research results show that adding large particle size(50μm or more)metal aluminum powder(including additives)can effectively improve the surface high gloss effect of ABS.Combined with the high gloss seamless injection molding process,the glossiness can reach 90 or more,the brightness can reach 80 or more,and the pencil hardness can reach F or more.In addition,adding silicone powder can reduce the surface friction coefficient of ABS,but the addition ratio needs to be controlled at around 1%.And the ABS/PMMA alloy material without spraying can further improve the surface hardness,making it reach H or above.The application of high gloss scratch resistant and spray free ABS material based on high gloss seamless injection molding process is feasible in the field of injection packaging.
