Paragraph 0297-0298; 0302-0304, (2019/01/23)
The invention relates to a phosphazene compound, a composite containing the phosphazene compound, a flame retardant containing the composite and application. The crystal form of the cyclotriphosphazene derivative flame retardant synthesized by using the method is most stable, and the cyclotriphosphazene derivative flame retardant is high in heat stability and high in flame retardant efficiency; moreover, when the crystal type cyclotriphosphazene derivative flame retardant synthesized by using the method is added into a material, such as engineering plastics, general-purpose plastics, a lithiumion battery electrolyte, a flame retardant fabric and flame retardant paper, a high flame retardant performance is achieved, the crystal form is stable, the flame retardant is resistant to drip, onlyan extremely small adding amount is needed, the flame retardant performance of the material can reach the V-0 standards, and other properties of the material are little affected.
