Description
Technical field
The invention belongs to flame retardance of polymer fields, and in particular to sulphur-nitrogen-phosphorus containing double DOPO, diphenyl sulfone structural unit
The preparation method of ternary synergistic flame retardant, and it is applied to the flame-retardant modified of the macromolecule resins such as polyurethane, ABS.
Background technique
High polymer material is widely used in each department of the national economy such as industry, agricultural, military affairs, but most of high
Polymers belongs to petroleum base combustible material, and polarity oxygen index (OI) is lower than 21, and heat release rate is high when burning, and calorific value is big, flame propagation speed
Degree is fast, is not easy to extinguish, and generally can also produce thick smoke and toxic gas, grave danger caused by the security of the lives and property of people.
There are the secondary hazards such as thickness, the releasing of toxic or corrosive gas when traditional halogen fire proofing burns, to personal safety structure
At seriously threatening.Attention with the development and people of flame-retarded technology to environmental protection and personal safety, Halogen, low cigarette,
Less toxic, high-fire resistance environmental protection fire retarding agent has become research hotspot.Chinese patent CN 101278001A is using phosphorous acid and sub- phosphine
Fire retardant of the ester derivant of the phosphorous oxyacid of acid as polyurethane resin, when additive amount reaches 10wt.% or so, poly- ammonia
For the vertical combustion grade of ester resin up to UL-94V-0 grades, flame retardant property is suitable with DOPO.However, without rigidity in its molecular structure
Ring causes its thermal stability and chemical stability to decline, and synthesis technology is complicated, and industrialized production is difficult.For ABS fire retardant
System, Chinese patent CN 104277410A report the mixing flame-retardant system of a kind of bromide and antimony oxide, although ABS hangs down
Straight combustion rating reaches UL-94V-0 grades, but amount of flame-retardant agent reaches 12wt.% or more, and halogen and heavy metal form, and cause
Serious environmental pollution.
Derivative containing DOPO is fire-retardant since its thermal stability and chemical stability are high as a kind of novel flame redundant material
Performance is significant, and Halogen, it is smokeless, environmentally friendly, not easy to migrate, carbon yield is high the features such as, be macromolecule resin halogen-free flameproof in recent years
Research hotspot.At this stage, phosphorus-hydrogen bond active in DOPO molecular structure, is mainly prepared by nucleophilic displacement of fluorine mode and is contained
The fire retardant of DOPO structural unit.However, facile hydrolysis containing phosphorus series compound generates the toxic gases such as hydrogen phosphide, therefore actually answering
There is certain limitation in.Therefore, how to coordinate low phosphorus content and excellent flame retardancy, become technical bottleneck at this stage.In
103421212 A of state patent CN introduces hydroxyl in DOPO structure, and cured reaction-type flame-retarding can be participated in by being prepared for one kind
Agent, when epoxy resin vertical combustion grade reaches UL-94V-0 grades, effective phosphorus content is still higher than 1.8wt.%;Chinese patent CN
103865101 A introduce aromatic amine in DOPO, phosphorus nitrogen synergistic based flame retardant at preparation, although available phosphorus content is reduced to
0.75wt.%, but its synthesis technology complexity, purification difficult, it is difficult to industrialized production and application.On the other hand, sulfur-bearing based flame retardant,
With excellent fireproof performance, the advantages such as additive amount is few.Therefore, by closing the nuclear structure segment of DOPO, diphenyl sulfone
Reason assembling and modification, prepare phosphorus nitrogen and sulphur synergistic based flame retardant, solve that existing fire retardant performance is poor, phosphorus content is high, conjunction
At the technical problem of complex process.
Summary of the invention
The technical problem to be solved in the present invention is to provide sulphur-nitrogen containing double DOPO, diphenyl sulfone structural unit-phosphorus ternary associations
Imitate the preparation method of fire retardant;It is good with macromolecule resin compatibility that the based flame retardant has, and chemical and thermal stability is high, effective
When phosphorus content is 0.22wt.%, vertical combustion grade is up to UL-94V-0 grades.
To solve the above-mentioned problems, the technical scheme is that
DOPO and 3,3/,4,4/Tetramino diphenyl sulphone (DPS) occurs Atherton-Todd reaction and generates containing DOPO, diphenyl sulphone (DPS) structure
The phosphorus nitrogen sulphur synergistic fire retardant of unit, particular chemical formula are as follows:
The preparation method of diphenyl sulphone (DPS) nitrogen phosphorus sulphur synergistic flame retardant containing DOPO, comprising the following steps:
DOPO (miscellaneous phenanthrene -10- the oxidation of the miscellaneous -10- phosphine of 9,10- dihydro-9-oxy is sequentially added in the container equipped with agitating device
Object), 3,3 ', 4,4 '-tetramino diphenyl sulphone (DPS)s, carbon tetrachloride and solvent, stirring is uniformly mixed system, under conditions of ice bath,
Organic base is added into reaction system, reacts at room temperature, filtrate, filtrate is obtained by filtration after the reaction was completed in TLC tracking reaction process
After extraction is washed, is concentrated, normal heptane-acetone (V is addedNormal heptane∶VAcetone=1: 4) being allowed to precipitate, be dried in vacuo to obtain the diphenyl sulphone (DPS) containing DOPO
Nitrogen phosphorus sulphur synergistic fire retardant.
3,3 ', the 4,4 '-tetramino diphenyl sulphone (DPS), DOPO, carbon tetrachloride, organic base molar ratio be 1.0: (4.4~
6.0): (4.4~6.0): (4.4~6.0).
The solvent is methylene chloride, ethyl acetate, acetonitrile, tetrahydrofuran, N,N-dimethylformamide, one in chloroform
Kind is a variety of.
The solvent usage is 4~8 times of DOPO mass.
The organic base is selected from one of trimethylamine, triethylamine, sodium methoxide, sodium ethoxide or a variety of.
Diphenyl sulphone (DPS) nitrogen phosphorus sulphur synergistic flame retardant prepared by the present invention containing DOPO has thermal stability and chemical stabilization
Property height, Halogen, suppression cigarette, with when macromolecule resin compatibility is good, effective phosphorus content is down to 0.22wt.%, vertical combustion grade can
