摘　　要：对凹印金粉表面进行涂覆及改性研究,并对改性后的凹印金粉进行了抗氧化性、比重、水面遮盖力、漂浮性等性能检测。结果表明,采用复合改性剂对凹印金粉进行表面涂覆和改性,提高了凹印金粉的抗氧化性、水面遮盖力和漂浮性,降低了凹印金粉的比重,从而提高了凹印金粉的综合指标。Surfaces of concave printing golden powder are modified and coated. Oxidation resistance, specific gravity, covering power of water and floating of modified concave printing golden powder are measured. Results show that oxidation resistance, covering power of water and floating of concave printing golden powder are raised, but the specific gravity is decreased when the surfaces of the concave printing golden powder are modified and coated by means of composite reagents. Therefore, the synthetic index is enhanced greatly.

关 键 词：改性剂 表面涂覆 表面改性
