Zusammenfassung: | The invention relates to a preparation method of a supramolecular flame retardant network with a graphite-like structure, which comprises the following steps: reacting organic amine containing a s-triazine structure with cyanuric acid in a solvent at the reaction temperature of 30-150 DEG C to obtain a target product, or reacting the organic amine containing the s-triazine structure with cyanuric acid under a solid phase condition at the temperature of 150-350 DEG C to obtain a target product. According to the invention, the supramolecular flame retardant network is not only connected by covalent bonds and hydrogen bonds in layers, but also tightly controlled by Van der Waals force among the layers, and has a long-range ordered structure; in the initial stage of combustion, the graphite-like structure of the flame-retardant polymer material can relatively slip to form a tight smoke shielding layer, and meanwhile, heat accumulated in the polymer material can be quickly transferred along covalent bonds, hydroge |
