Fire retardant dibenzyl phosphinyl-N-cage phosphate amine compound, and preparation method thereof

摘要: The invention relates to a fire retardant dibenzyl phosphinyl-N-cage phosphate amine compound, and preparation method thereof. structure of the compound is disclosed in invention. comprises following steps: cage triethylamine are added into an organic solvent, air reactor replaced by nitrogen gas, at 20 DEG C, diphenylphosphinyl chloride drop 1h, wherein chloride: :triethylamine molar ratio controlled tobe 1:1:1 1:1.2:1, dropwise adding temperature be 50 C or lower; after adding, increased 80 110 for 4 6h backflow reaction,then obtained product subjected cooling, filtering, water washing, vacuum drying so as obtain slightly yellow solid amine. excellent phosphonate cooperative retardant, suitable taken retardants polyamide, polyester, polyurethane, glass fiber reinforced plastic, polyolefin materials; simple; equipment investment low; industrialized production convenient realize.
