The invention discloses a zirconium phosphate-melamine cyanurate reactive flame retardant and a preparation method and application thereof. The invention utilizes the porous characteristics of zirconium phosphate and the swelling effect of the alcoholizing agent to enlarge the layer spacing of the zirconium phosphate, so as to provide space for the introduction of melamine cyanurate in the later stage. The urate composite material makes it surface active, can be well compatible with polyether polyol, and reacts with curing agent, so that zirconium phosphate-melamine cyanurate has the characteristics of reactive flame retardant, with phosphorus Nitrogen compounding theory ensures the flame retardant efficiency of composite flame retardants, significantly improves the compatibility of flame retardants in polyurethane, and then uses it in polyurethane composite materials to significantly reduce the amount of flame retardants added and improve The mechanical properties of the composite material are improved, so that the UL‑94 test of the composite material reaches V‑0 level, the oxygen index reaches more than 29%, and the compressive strength reaches 241Kpa. |
