Description
Technical field
The present invention relates to technical field of flame retardant, and in particular to a kind of surface migration sex flame retardant of Nitrogen-and Phosphorus-containing and its preparation
Method.
Background technique
Halogenated flame retardant is containing halogens and with a based flame retardant of halogens fire retardation.Four kinds of halogen system
Halogen system element fluorine (F), chlorine (Cl), bromine (Br), iodine (I) all have anti-flammability, and flame retardant effect is successively increased by the sequence of F, Cl, Br, I
By force.It is most strong with iodine flame retardant.In production, only chlorine class and brominated flame retardant are widely used and fluorine class and iodine based flame retardant
Rare application, this is because C-F key is too strong and cannot effectively capture the C-I key of free radical and the fire retardant containing I in fluorine-containing fire retardant
Too weak easily being destroyed affects polymer performance (such as photostability), has lost flame retardant property just below degradation temperature.
9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, abbreviation DOPO contain P-H key in structure, to alkene
Hydrocarbon, epoxide and the great activity of carbonyls can react and generate many derivatives.DOPO and its derivative are due to molecule
Contain cyclohexyl biphenyl, phenanthrene ring, O=P-O key in structure, so there is stronger flame retardant property than common organophosphorus ester.By
Saito reported its synthetic route in 1972 for the first time.DOPO and its derivative can be used as response type and additive flame retardant, close
At fire retardant Halogen, smokeless, nontoxic, do not migrate, flame retardant property is lasting.While improving the flame retardant property of material, not shadow
Ring the mechanical performances such as the mechanical strength of material.It can be used for the multiple materials such as polyamide, linear polyester, polyurethane, epoxy resin
Flame retardant treatment, foreign countries are widely used in the fire-retardant of materials such as pressurized layer, circuit board in plastics for electronics, brass.Although having
Good flame retardant property, but with the increase of additional amount, some detrimental effects can be brought to the performance of material itself.
Summary of the invention
In view of the above deficiencies, it is an object of the present invention to provide a kind of formula is reasonable, it is easy to accomplish, flame retardant effect
The surface migration sex flame retardant of good Nitrogen-and Phosphorus-containing.
The second object of the present invention is, provide it is a kind of can quick Fabrication go out the surface migration sex flame retardant of above-mentioned Nitrogen-and Phosphorus-containing
Preparation method, with the increase of phosphorus content in solidfied material, the anti-flammability of solidfied material increases；When flame retardant agent content reaches 5~
When 10%, solidfied material can achieve UL94, and V-0 grades.
To achieve the above object, the technical solution provided by the present invention is: a kind of surface migration sex flame retardant of Nitrogen-and Phosphorus-containing,
