The flame-retardant paper prepared by this method is free of any harmful flame retardant component and will not reduce the strength of the paper; and the paper is high in strength and good in toughness, can be used as an environmental-friendly, degradable, temperature-resistant and flame-retardant material, and has a wide range of applications.
