告别“毒颜料”！我科学家突破环保颜料技术

Core Viewpoint - The development of a new generation of environmentally friendly pigments by a research team led by Dong Bin addresses the health risks associated with traditional industrial pigments that contain toxic heavy metals, offering a safer and more cost-effective alternative [1][3]. Group 1: Environmental and Health Impact - Traditional industrial pigments often contain heavy metals like lead, cadmium, and mercury, which pose serious health risks, especially to children [1]. - The new eco-friendly pigments developed by Dong Bin's team are free from toxic heavy metals and have passed SGS standard testing, fully complying with green standards [3]. Group 2: Technological Innovation - The new pigments utilize a "wide bandgap matrix + rare earth doping" technology, leveraging China's rare earth resource advantages to achieve high saturation colors in green, yellow, orange, and red [1]. - This innovative approach not only enhances color quality but also improves thermal resistance, aging resistance, and color fastness compared to traditional pigments [1]. Group 3: Economic Viability - The new environmentally friendly pigments are expected to reduce production costs significantly, with prices potentially dropping by over 60% after large-scale production, making them cheaper than some traditional toxic pigments [3]. - The introduction of these pigments is seen as a breakthrough that addresses toxicity and environmental pollution while demonstrating significant advantages in stability and production costs [3].
