Abstract

The invention discloses a flame retardant catalyst of a metal organic frame complex and a preparation method thereof. Cyanuric chloride and 4-aminopyridine are adopted to synthesize a triazine-based organic metal ligand; and then the ligand and metal acetate undergo coordination reaction, so as to obtain the flame retardant catalyst of the metal organic frame complex. A synthesis process is easy to operate, the product aftertreatment is simple, and the flame retardant catalyst is suitable for industrial production. The flame retardant catalyst can improve char formation efficiency and flame restardation of a flame-retardant system, the addition amount of a flame retardant can be effectively reduced, and the flame retardant catalyst further has the advantages of good compatibility, thermal stability, migration resistance and environmental friendliness and the like and is a good flame retardant synergist.

Description

technical field [0001] The invention relates to a metal-organic framework complex flame-retardant catalyst and a preparation method thereof, belonging to the field of flame-retardant synergists in flame-retardant material science. Background technique [0002] Polymer materials are widely used in various departments of production, scientific research, national defense and people's daily life. However, ordinary polymer materials are highly flammable, which undoubtedly leaves a great safety hazard to people's lives and properties. Therefore, improving the thermal stability of materials and enhancing the flame resistance of materials has become a hot spot in the research of material modification. As an additive that can effectively prevent materials from being ignited and inhibit flame propagation, flame retardants are widely used to improve the fire resistance of materials, and have become important additives for synthetic polymer materials. [0003] However, if a certain fla...
