Abstract: In order to visually analyze the knowledge base, research hotspot, research frontier and development trend of domestic nano flame retardant technology，1 156 domestic literatures on nano flame retardant technology collected in CNKI database from 2000 to 2019 were selected as research samples. The knowledge map was studied with bibliometrics and CiteSpace software. The key words co-occurrence network map and the distribution table of emergent words were drawn, and the possible new research directions in this field were explored. The experimental results show that: After the research of nano flame retardant technology in China has gone through three development frontier stages of "early frontier", "medium frontier" and "latest frontier", the field of nano flame retardant will continue to lead the future with clean and efficient flame retardant new technology.

Key words: nano flame retardant, CiteSpace, visual analysis, knowledge map
