一种氮磷系共聚阻燃聚酰胺树脂及其制备方法和应用
By embedding nitrogen-phosphorus flame-retardant salts into the polyamide molecular chain, the flame retardancy of polyamide resin is improved, from UL94-V2 to UL94-V0, which solves the problem of insufficient flame retardancy of existing polyamide resins and broadens its application scope.

AI Technical Summary
The flame retardant properties of existing polyamide resins are only UL94-V2, which cannot reach UL94-V0, thus limiting their application scope. Furthermore, existing modification methods increase production processes and costs.
The flame retardancy of polyamide is improved by embedding nitrogen-phosphorus flame retardant salts into the polyamide molecular chain, specifically by melt polycondensation of the nitrogen-phosphorus flame retardant salt formed by [(6-oxo-6H-dibenzo-(c,e)(1,2)-oxophosphorus hexane-6-one)-methyl]-succinic acid and melamine with polyamide salt.
This technology has improved the flame retardancy of polyamide resin from UL94-V2 to UL94-V0 without requiring additional production steps, thus broadening its application areas.
