Description
Technical field
The invention belongs to imidazole ion liquid type fire retardant and preparation method thereof, relate in particular to a kind of containing young laying ducks in cage knot
The preparation method of the imidazole ion liquid type fire retardant of structure.
Background technology
Ionic liquid as an eco-friendly compound of class, because there is uniqueness and the physicochemical properties of excellence in recent years
To development at full speed be widely applied, as it is almost without vapour pressure, the most volatile, liquid journey wide ranges, Heat stability is good,
Thermal capacity is big, electrochemical window width, the feature such as non-combustible, is referred to as " green solvent " that can substitute conventional organic solvents.
The more important thing is that the molecule designability of ionic liquid is strong, can be by the alkyl chain length of regulation cation, change alkyl substituent
Kind, selecting suitable anion to regulate physical property and the chemical property of ionic liquid, this makes us can be according to tool
The needs of body design " functional ionic liquids ".At present ionic liquid in synthesis, catalysis, isolation technics, electrochemistry, divide
Analysis chemistry and the most a lot of research of nanometer material science aspect, and ionic liquid is as the plasticizer of macromolecular material, dispersion
The report of the functional aid such as agent, fire retardant also day animando.
Patent CN102924749A reports a kind of Ionic liquid-type phosphate fire retardant of research synthesis, and is answered
Join and add in polypropylene (PP) for expanding fire retardant, obtain preferable flame retardant effect.But, in that patent, closed
The ion liquid type fire retardant become needs to quote a certain amount of halogen and can reach corresponding effect, and along with macromolecular material
The expansion of application, people are more and more higher to the requirement of fire retardant and fire proofing, and halogenated flame retardant is because of the process in burning
Middle meeting discharges a large amount of dense smoke and the corrosivity toxic gas such as two English, benzene furan, is the most gradually used by restriction.And should
The fire retardant that patent is reported needs to coordinate ammonium polyphosphate, tetramethylolmethane and tripolycyanamide to be re-dubbed expansion type flame retardant to be added
Just playing preferable flame retardant effect in material, be used alone the unsatisfactory of effect, it is certain that this makes it have in the application
Restricted.
Summary of the invention
It is an object of the invention to for prior art exist defect, first provide a kind of imidazoles containing young laying ducks in cage structure from
Sub-liquid type fire retardant, this fire retardant does not contains halogen, has the thermal stability of excellence.
The two of the purpose of the present invention are to provide the preparation side of the above-mentioned imidazole ion liquid type fire retardant containing young laying ducks in cage structure
Method.
The imidazole ion liquid type fire retardant containing young laying ducks in cage structure that the present invention provides, it is characterised in that its general structure is such as
Under:
In formula, X is the alkyl of C=1-20, phenyl or phosphate-based, and the most phosphate-based structure is as follows:
Y is the alkyl of C=1-20, phenyl or p-methylphenyl, is applied in Merlon by this fire retardant, is 0.1~5wt% at addition
Time, its limited oxygen index is 29.5~32.0%.
The alkyl of the preferred C=1-8 of Y described in above fire retardant or p-methylphenyl.
The preparation method of the above-mentioned imidazole ion liquid type fire retardant containing young laying ducks in cage structure that the present invention provides, its feature exists
As follows in processing step and the condition of the method:
1) at N2Under protection, by 1-epoxide phospha-4-methylol-2,6,7-trioxa-l-phosphabicyclos [2.2.2] octane (PEPA) and tiing up
Acid agent is sequentially added in solvent I, and stirring is slowly added dropwise substituted sulfonic acid chlorine after dissolving mix homogeneously to major part PEPA again, and
Reacting 6-15h at 25-50 DEG C, reaction is distilled off solvent I after terminating, more scrubbed, obtain intermediate after drying, its
Middle acid binding agent and PEPA mol ratio are 1-1.2:1;PEPA is 1:1-1.5 with the mol ratio of replacement sulfonic acid chloride, and it reacted
Journey is as follows:
2) gained intermediate is first dissolved completely in solvent II, is subsequently adding substituted imidazole, and at N2It is warming up under protection
60-85 DEG C of reaction 48-72h, is distilled off solvent II, scrubbed, after drying, wherein substituted imidazole and intermediate
Mol ratio is 1-1.2:1;Its course of reaction is as follows:
Solvent I used in said method is any one in dichloromethane, acetone or oxolane.
Solvent II used in said method is in acetone, acetonitrile, 1-Methylimidazole., 1-ethyl imidazol(e) or 1-propyl imidazole
Any one.
Acid binding agent used in said method is triethylamine or pyridine.
The structural formula replacing sulfonic acid chloride used in said method is:
In formula, Y is alkyl or the p-methylphenyl of the alkyl of C=1-20, phenyl or p-methylphenyl, preferably C=1-8.
The structural formula of substituted imidazole used in said method is:
In formula, X is the alkyl of C=1-20, phenyl or phosphate-based, and the most phosphate-based structure is as follows:
The present invention compared with prior art, has the advantage that
1, without halogen in the structure of the imidazole ion liquid type fire retardant containing young laying ducks in cage structure provided due to the present invention,
Thus this fire retardant can meet the requirement of environmental protection sustainable development now, have a good application prospect;
2, containing sulfonic acid in the anion of the imidazole ion liquid type fire retardant containing young laying ducks in cage structure provided due to the present invention
Root, thus in makrolon material, have only to add minimal amount of (0.1wt%) fire retardant i.e. can reach preferable fire-retardant effect
Really, the negative effect that material mechanical performance is brought by additive flame retardant is decreased.
3, there is the thermal stability of excellence owing to the present invention containing the imidazole ion liquid type fire retardant of young laying ducks in cage structure,
Its decomposition temperature is all more than the processing temperature of the major part macromolecular materials such as Merlon, thus can be prevented effectively from it in processing
During oxidation Decomposition occurs, so that losing excellent anti-flammability.
4, the imidazole ion liquid type fire retardant containing young laying ducks in cage structure provided due to the present invention can individually make in use
With, it is not necessary to carry out compounding just there is preferable anti-flammability with other flame-retardant composition, thus both avoided and found its matched
Its flame-retardant composition carries out the trouble compounded, and can reduce again the restriction of actual application.
5, the preparation method technological operation that the present invention provides is simple, with low cost, and reaction products therefrom yield is high, reacts former
Material substituted imidazole is recyclable again with, environmental protection and saving.
