Organic phosphine flame retardants containing CP key chemical stability enhancement, water , solvent extracted flame retardant performance , low-smoke , non-toxic , impact on the mechanical and physical properties of the material small advantage , so organic phosphine flame retardants phosphorus flame retardant , is the most widely used , acclaimed the best prospects for the development of flame retardants varieties , can be widely used in epoxy , polyester , polyurethane , polyolefin , nylon and other polymer flame retardant . Thesis of neopentyl glycol , carboxymethylcellulose, ethyl phenyl phosphonic acid and phosphorous acid trimethyl ester as basic reaction raw materials, was divided into three parts 10 new organophosphine type flame retardant were synthesized : polymer compound polyimide B phenyl Ci Lin acyloxy piperazine , poly- acyloxy ethylphenyl phosphonooxymethylpaclitaxel ethylenediamine , the polyamic ethyl phenyl phosphinic hydrazide ; , ethyl phenyl phosphonic hydrazide polyimide , polymer compound of aluminum , zinc and metal salts; macromolecular compound N , N' - bis ( carboxymethyl ethyl phenyl Phosphonoacetyl ) ethylenediamine aluminum , zinc salts ; N , N' - bis ( carboxymethyl ethyl phenyl phosphinate ) hydrazine aluminum , zinc salts, ; ethylenedioxythiophene phosphonic acid, diethyl ester; and existing compounds, 1,4 - bis (5,5 - dimethyl - 1 ,3 - dioxo-2 - P cyclohexyl phosphono ) ethylenediamine , 1,4 - bis ( 5,5 - dimethyl -1,3 - dioxo-2 - naphthalene ring hexyl phosphono ) piperazine were optimized and improved , and some of their flame retardant properties , hoping can find superior performance flame retardant products . Compounds synthesized by IR, NMR , melting point , elemental analysis , differential thermal analysis, structural characterization and analysis of its structural features and we needed to structure .
