A porphyrin phosphate compound, a preparation method and its application as a flame retardant belong to the technical field of functional organic molecule design and synthesis. The general structural formula of the porphyrin phosphate compound is P, and the preparation method mainly uses p-hydroxybenzaldehyde and halophosphate as raw materials, and synthesizes benzaldehyde containing phosphate through nucleophilic substitution reaction; and then condenses with pyrrole to prepare Porphyrin compounds with four phosphate esters. The invention introduces phosphorus element into the porphyrin ring by chemical method, maintains the excellent properties of porphyrin and phosphorus element, has good solubility and self-assembly ability, can be well dispersed in the polymer material, and shows good performance. compatibility. Since porphyrin exists in the human body and plants, and the color is purple, the porphyrin phosphate P of the present invention can be added as a biomass flame retardant to polymer materials such as epoxy resin, polylactic acid, polybutylene terephthalate Among the glycol esters, it has coloring and flame retardant effects. |
