Flame retardant with nitrogen-containing phosphonate and synthesis method of flame retardant

The invention discloses a flame retardant with nitrogen-containing phosphonate and a synthesis method of the flame retardant, belongs to the field of flame retardant synthesis and particularly relatesto a flame retardant and a synthesis method thereof. The problems of large addition amount, deep color, poor durability and low flame-retarded efficiency are solved. The chemical name of the flame retardant with the nitrogen-containing phosphonate is polymethyl phosphonic acid piperazine ester; the preparation method comprises the steps that dimethyl methylphosphate is taken in a reaction container, piperazine and a catalyst are added, sufficient stirring is conducted until the mixture is dissolved, and after heating and a reaction for several hours, fraction methyl alcohol is collected; after the reaction is ended, cooling is conducted, and the product polymethyl phosphonic acid piperazine ester can be obtained. A synergistic effect exists between a nitrogen element and a phosphorus element in the flame retardant, the two ends of each flame retardant molecule contain amidogen, in the curing process, the amidogen can react with epoxy groups of epoxy resin, so that the epoxy resin obtain permanent flame retardance, and the char yield of the epoxy resin is obviously increased. The flame retardant is applied to preparation of the flame retardant with the nitrogen-containing phosphonate.
