Beschreibung
Zusammenfassung:	The invention discloses a reflecting film and a preparation method thereof, and a flame retardant is obtained by taking phytic acid and 3, 5-diamino-1, 2, 4-triazole as reactants and carrying out a synthetic reaction. According to the flame retardant, a phosphorus-rich structure of biomass phytic acid is combined with nitrogen heterocyclic rings in a 3, 5-diamino-1, 2, 4-triazole structure to jointly participate in catalytic carbonization, transfer of heat and oxygen is blocked through a barrier effect, flue gas is inhibited, and a condensed phase flame retardant effect is formed; besides, the phosphorus-rich structure can release phosphorus-containing free radicals in the high-temperature decomposition process, the flame extinguishing effect is achieved in the gas phase, and the fire safety of the reflecting film can be remarkably improved through the solid-gas double-phase flame retardant mechanism. 本发明公开了一种反射膜及其制备方法，其中阻燃剂是以植酸和3,5-二氨基-1,2,4-三唑为反应物进行合成反应得到。本申请阻燃剂中生物质植酸的富磷结构结合3，5-二氨基-1，2，4-三唑结构中的氮杂环共同参与催化炭化，通
