The invention discloses a high flame retardant modacrylic fiber and its production method, the chemical composition of the fiber contained in the copolymerization of acrylonitrile, vinyl chloride, two partial acrylamide methyl propane sulfonic acid sodium, five two and ten two bromine antimony oxide, ethyl benzene, the five oxidation of two antimony in the fiber contained in the weight ratio of 6.5 to 10%, the ten bromo two benzene ethane in the fiber contained in the weight ratio of 5.5 to 10%. The production method of ten bromo two benzene ethane, the polymer solution and two methyl formamide are fully mixed, and through grinding and filtering to prepare ten bromo two ethyl benzene solution; after adding two antimony colloid solution and two DMF aqueous solution polymerization and oxidation of five single liquid after in full after mixing, filtering, and then add into the online continuous system of ten bromo two ethyl benzene solution, finally sent to the spinning process. The invention has excellent flame retardancy, environmental protection and comprehensive performance, and is widely used in various fields, especially in the field of special flame retardant fabrics.
