Embodiment Construction
[0014] Technical scheme of the present invention is as follows:
[0015] A kind of preparation method of novel flame retardant, comprises steps as follows:
[0016] Under the condition of using a solvent, mix an organic compound containing an amino group, an organic compound containing a phosphorus-hydrogen bond, and an aldehyde (ketone) compound containing not less than one phenolic hydroxyl group in the molecular structure, and perform a one-step reaction to obtain a new type of inhibitor. Fuel. The reaction equation is as formula (1):
[0017]
[0018] In formula (1), R 2 to R 5 Can be a hydrogen atom or an organic group other than a hydrogen atom, R 1 , R 6 , R 7 It is an organic group that is not a hydrogen atom.
[0019] According to the present invention, preferably, the amino-containing organic compound is an organic compound containing no less than one amino group, including small molecular compounds containing amino groups, linear polymers containing amino ...
