Since it has the characteristics of laminate cations adjustable, interlayer anion exchangable and acid-base property, received much attention of researchers in many fields such as medicine, ion exchange, reaction catalysis, and material flame retardant. The unique physical and chemical properties make it as a flame retardant material with outstanding advantages such as halogen-free, produce non-toxic and corrosive gases, flame retardant and smoke suppression. Study on ion-modified hydrotalcite is becoming a hot spot in the research of flame retardant materials. However, it also has shortcomings such as it’s low thermal stability, easy-reaggregation and poor dispersion. Therefore, domestic and foreign scholars have carried out some research on hydrotalcite modification. This review mainly expounds the research progress of domestic and foreign scholars in the cationic modification and anion modification of hydrotalcite flame retardants in recent years, The research and application prospects of hydrotalcite are prospected, in the biomass material flame retardant, low-cost hydrotalcite flame retardant synthesis, hydrotalcite synergistic flame retardant research, hydrotalcite flame retardant industrial production new process and equipment, clean preparation technology and other aspects. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书修改说明 -->
