Flame-retardant toluene diisocynate derivative and synthetic method thereof

The invention relates to a Flame-retardant toluene diisocynate derivative and a synthesis method thereof, and belongs to the technical field of polyurethane materials. The general chemical structuralformula of the flame-retardant toluene diisocynate derivative is Brn-Ar-(NCO) 2, wherein Ar is a benzene ring, and n is 1-4. According to the synthesis method of the derivative of the flame-retardanttoluene diisocynate, bromophenylenediamine micromolecules with Br elements are adopted for phosgene reaction, and then the derivative of the flame-retardant toluene diisocynate is obtained through refining. The flame-retardant effect is good, the influence on the physical property of a foam product is small, and flame retardance is lasting.
