Single-component phosphor-nitrogen double-ring cage-shaped macromolecular intumescent flame retardant as well as preparation method and application thereof

摘要: The invention discloses a single-component phosphor-nitrogen double-ring cage-shaped macromolecular intumescent flame retardant as well preparation method and an application thereof. the comprises following steps: at 90-110 DEG C, nucleophilic substitution reaction is carried out between pentaerythritol phosphorous oxychloride, PEPA obtained; cyanuric chloride -5-10 C for 3-6 hours, product diamine compound 50-60 5-10 then hours; finally obtained modification of polymers. Compared with prior art, prepared has advantages high retardation efficiency, good compatibility polymers, etc.; whose weight 20-25 wt% polypropylene can be added into endowing performance, widely applied to fields internal external decorative parts automobiles, furniture electric appliances, wires cables, building material, etc.
