【摘要】 利用文献计量学方法，以中国知网、SCI和国家知识产权局数据库为基础，通过对乙烯-乙酸乙烯酯共聚物（EVA）阻燃领域1990—2020年国内外公开出版的学术论文和专利技术进行检索，分析EVA阻燃技术的发展现状，揭示其文献增长、研究主题等特征，并尝试通过热点关键词分析不同共混体系和阻燃体系的论文数据，对研究热点进行总结。结果表明：2004年以前，国内外对EVA阻燃方向的研究关注有限；2004年以后，国内相关学术论文及专利申请的数量明显上升，与国外EVA阻燃方向的研究开发具有相同趋势。总体来看，目前，EVA阻燃体系仍然以无机填充型阻燃剂为主，而高效的阻燃协效体系设计、纳米阻燃剂应用技术的开发是未来的发展趋势。更多还原

【Abstract】 The method of bibliometrics is used to search the academic publications and patent technologies in the field of flame retarded ethylene-vinyl acetate copolymer(EVA) from 1990 to 2020 on the basis of China National Knowledge Infrastructure,SCI and China National Intellectual Property Administration database to analyze the technological development of flame retardancy of EVA. Then it reveals the characteristics of the related publications including literature growth,research themes,etc. The research hotspots are summarized by means of the hot keyword analysis on different blending systems and flame retardant systems. The results show that before 2004,relative domestic and foreign publications and patent applications are relatively less. Since 2004,related publications and patents have increased significantly following international trends. Overall,the current flame retardancy technologies of EVA are still dominated by inorganic flame retardants,and the future trends include novel efficient synergistic flame retardant system and nano technologies.更多还原
