Abstract
The invention discloses a fire retardant containing boron phenyl phosphonic acid esters and a preparation method thereof. The constitutional formula of the fire retardant containing the boron phenyl phosphonic acid esters includes that R is -H, -CH3, -CH2CH3, -CH (CH3)2 or -CH2CH2CH2CH3, and n can be one to five. During preparation, hydroxide radical benzyl alcohol and organic solvent are heated after being mixed, then boron monomers are added into the mixture of the hydroxide radical benzyl alcohol and the organic solvent, the whole system is heated to react under the condition of boiling and then is cooled, and boric acid hydroxide radical benzol methyl ester midbody is prepared. Phenyl phosphorus acyl dichloro and organic solvent are added into the boric acid hydroxide radical benzol methyl ester midbody to react for five to twelve hours, then phenol is added into the boric acid hydroxide radical benzol methyl ester midbody, and the fire retardant containing the boron phenyl phosphonic acid esters is obtained after excessive phenol is removed and the solvent is dried. The fire retardant is solid, cannot move by 'squeezing' and has lower affection on impact performance of high polymer materials.
