Abstract
The invention discloses a method for preparing a halogen-free high-efficiency flame retardant aryloxy cyclotriphosphazene compound. The flame retardant is a pure white crystal product prepared by reacting sodium phenate and hexachlorocyclotriphosphazene serving as raw materials with dioxane serving as a solvent under heating and stirring, filtering and purifying. The preparation method of the flame retardant overcomes the defects of long reaction time, a yellow product color and high production cost existing in the conventional synthesis method commonly. The prepared flame retardant has the characteristics of high efficiency, no halogen, flame retardance, no toxicity, low smoke and the like, has high compatibility with most of organic polymer materials, and has processing stability and using stability.
Description
Technical field
The present invention relates to a kind of preparation method of fire retardant, specifically is a kind of preparation method of Halogen efficient flame-retarding agent aryloxy cyclotrinitrile phosphide.
Background technology
Low bromo etherate fire retardant, organism such as tetrabromodiphenyl ether, pentabromodiphenyl oxide, hexabromo phenyl ether, seven dibromodiphenyl ethers, octabromodiphenyl ether have persistency organic contaminant to environment, therefore are put in " Convention of Stockholm " appendix A to ban use of.Decabromodiphynly oxide is as one of broad-spectrum organic bromine flame retardant; Widespread use in organic polymer materials such as polyolefine (PE, PP, ABS), polyester (PBT, PET), epoxy resin, fiber; Although decabromodiphynly oxide is not directly listed in the forbidding scope of " Convention of Stockholm "; But the various low replacement bromo ether that it produces in production or degradation process; Still there is the problem that causes the environmental persistence organic contamination, also thereby in succession forbidden by the laws and regulations of China and European Union.Therefore, once the flame retarded polymeric material field of widespread use decabromodiphynly oxide presses for alternative flame retardant products.At present, the developing direction of BACN is: on flame retardant properties, have characteristics such as highly effective flame-retardant, nontoxic, low cigarette; Aspect processing Yu by the ignition resistant substrate material, have excellent compatibility and processing characteristics; In use do not move; Has excellent photostabilization; Aspect the ignition-proof element selection the halogen-free flameproof thing of compliance with environmental protection requirements such as reselection procedure phosphorus system, nitrogen system, silicon system.Use as fire retardant, its flame retarding efficiency is high, and anti-hydrolysis is anti-oxidant, and living cigarette amount is low when burning or hot tearing, the low corrosion of degradation production, high low temperature use temperature wide ranges.
At present the compound method of the hexaphenoxycyclotriphosphazene (HPCTP) of report is mainly following: class methods are to react in THF or toluene with highly basic such as sodium Metal 99.5, NaH or NaOH and phenol earlier to make anhydrous sodium phenylate; Make HPCTP with hexachlorocyclotriphosphazene (HCCTP) reaction again; Yield about 70%～95%; Reaction times reaches 20～50 hours, and the use of sodium Metal 99.5, NaH causes reacting bad control; Another kind of method is that HCCTP, phenol, acid binding agent (salt of wormwood, triethylamine etc.) one are reacted in acetone solvent, product yield lower (being lower than 70%), and solvent and acid binding agent consumption are big; The separating treatment trouble; Or use HCCTP, phenol, NaOH to be raw material, and with the tetrabutylammonium chloride phase-transfer catalyst, chlorobenzene and water are solvent; Synthetic HPCTP, the about yield 75% of productive rate.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of Halogen efficient flame-retarding agent aryloxy cyclotrinitrile phosphide, the preparation method of this kind fire retardant overcomes ubiquitous long reaction time in the existing compound method, product colour jaundice, the deficiency that production cost is high.The fire retardant of preparation has efficient halogen-free anti-inflaming, and is nontoxic, and characteristics such as low cigarette have good consistency, processing stability and stability in use with most organic polymer materials simultaneously.
Technical scheme of the present invention is: a kind of preparation method of Halogen efficient flame-retarding agent aryloxy cyclotrinitrile phosphide comprises the steps:
A. it is subsequent use with hexachlorocyclotriphosphazene 4.5～6 to take by weighing raw material phenol sodium 12.0～17.9 by weight;
B. the dioxane that in reaction vessel, adds 90～120 weight parts is dissolved in load weighted sodium phenylate and hexachlorocyclotriphosphazene in the dioxane as solvent, carries out the heated and stirred reaction, and temperature of reaction is 70～100 ℃, and the reaction times is 8～15 hours;
C. reaction product is cooled off and left standstill, the layering of question response product, the upper strata is a yellow solution; When lower floor is light yellow solid, remove by filter lower floor's solid, the yellow solution that filtration is obtained carries out the primary purification processing; Obtain thick product; The thick product of gained is carried out the secondary purification processes, obtain the pure white crystal, be Halogen efficient flame-retarding agent aryloxy cyclotrinitrile phosphide.
Described primary purification treatment process is: with medium zero(ppm) water yellow solution is carried out crystallization and purification, drying obtains thick product white depositions.
Described secondary purification processing method is: thick product is carried out recrystallization with medium ethanol purify, drying obtains the pure white crystal.
The melting range of the Halogen efficient flame-retarding agent aryloxy cyclotrinitrile phosphide of the present invention's preparation is 110～114 ℃.
The invention has the beneficial effects as follows: among the present invention, the yield of aryloxy cyclotrinitrile phosphide reaches more than 85%, and purity is greater than 99%; Outward appearance is the pure white crystal, and solvent used in the preparation process is few, and safety and environmental protection; The scale prodn of synthesis and preparation process easy for industrialized; Production cost is low, replacing or reducing brominated flame-retardant and fire retardant material, promotes fire retardant and fire retardant material to have great importance on developing to low-carbon high-efficiency, eco-friendly direction.
Aryloxy cyclotrinitrile phosphide is the efficient halogen-free anti-inflaming agent, does not contain halogens in the molecule, phosphorus, nitrogen element content height; A lot of organic polymers had the good flame effect; Limiting oxygen index(LOI) LOI can be 30%～70%, and smoke density is low, satisfies the efficiently fire-retardant requirement of low cigarette environmental protection of Halogen.
