摘　　要：电子电器垃圾(WEEE)中的重金属(砷、汞、铅、镉、铬等)和卤素(溴、氯等)对环境有害,回收WEEE塑料是必要的。文章介绍了不同种类塑料在电子电气设备(EEE)中的功能和应用,包括电绝缘、隔热、阻燃等。综述了近十几年国内外废旧电子电器塑料的热解技术和化学改性再生方法,为电子废弃物中塑料的回收再利用提供参考,指出了我国废旧电器塑料资源化利用面临的问题。Heavy metals(arsenic, mercury, lead, cadmium, chromium, etc.) and halogens(bromine, chlorine, etc.) in waste electrical and electronic equipment(WEEE) are harmful to the environment, and recycling WEEE plastics is necessary. The functions and applications of different kinds of plastics in electrical and electronic equipment(EEE) are introduced, including electrical insulation, heat insulation and flame retardant. The pyrolysis technology and chemical modification and regeneration methods of WEEE plastics in recent ten years are reviewed. It provides a reference for the recycling of plastics in electronic waste, and points out the problems in the recycling of waste electrical and electronic equipment plastics in China.
