Description
Technical field
The present invention relates to the preparation method of a kind of inorganic-organic phosphate ester composite fire proofing.
Background technology
In recent years, along with polymeric material application in people's productive life constantly increases, particularly public transport, the demand growth of subway, light rail and bullet train, the polymeric material caused fire disaster that catches fire is in rising trend.Investigating and find, in fire fatality, 80% is not scorched to death, but the burned by-product produced smokes dead (anoxia and suction people toxic gas-CO, HBr, HCl etc.).When fire occurs, the temperature of hot spot steeply rises, and about 15min i.e. can reach 760 DEG C, and high polymer is easily generated imperfect combustion and over-emitting black exhaust, so that anoxia；On the other hand discharge various toxic gas in combustion, inhale poisoning after people and dead, such as CO (this gas is most), HC1, HCN gas etc., therefore, the fire-retardant attention increasingly causing people of polymeric material.But the most most flame-retardant polymers are mainly by adding what halogen flame realized, substantial amounts of smog and poisonous, harmful, corrosive gas can be produced when burning, cause " secondary disaster ", therefore, the low-smoke non-halogen flame-retardant of Study Polymer Melts material, the life and property loss that the generation and reduction fire for reducing fire is caused has great importance.Wherein using clean and effective halogen-free flame retardants is the important channel improving Flame Retardancy energy.
The halogen-free type fire proofing of research mainly includes phosphorus flame retardant, nitrogen system silicon-series five-retardant, expansion type flame retardant and Nano type fire retardant etc. the most both at home and abroad.Phosphorus flame retardant have Heat stability is good, non-volatile, do not produce corrosivity poison, the effect advantage such as persistently, be widely used.Phosphorus flame retardant is weak fire inhibitor, mainly fire-retardant based on condensed phase to flame retardance of polymer effect.
The fire retardant mechanism of phosphorus flame retardant mainly forms isolating membrane and reaches flame retardant effect, and the mode forming isolating membrane has two kinds:
1) thermal degradation products utilizing fire retardant promotes polymer surfaces rapid dehydration and carbonization, and then forms charring layer.Do not carry out producing combustion by evaporation and the decomposition combustion of flame due to simple substance carbon, therefore, there is fire-resisting protection effect.Its reason be the end product that phosphorus-containing compound thermally decomposes to yield be poly-Metaphosphoric acid, and it is strong dehydrant.
2) phosphorus flame retardant decomposes the nonvolatile glassy mass of generation under ignition temperature, and it is coated on the surface of polymer, and the protective layer of this densification plays the effect of sealing coat.
Phosphor-included additive mainly acts in condensed phase, and fire retardant mechanism is:
1. the poly-Metaphosphoric acid of formation is as dehydrant, and promotes into charcoal, and the generation of charcoal reduces the conduction of heat from flame to condensed phase；
2. phosphoric acid can absorb heat, because it prevent that CO is oxidized to CO2, reduces heating process；
3. the protective layer of the vitreous or liquid of pair condensed phase formation thin layer; therefore the heat between oxygen diffusion and gas phase and solid phase and quality transmission are reduced; inhibit char combustion process; reduce phosphonium flame retardant decomposes and following change occur: phosphorus flame retardant → phosphoric acid partially → phosphoric acid → poly-Metaphosphoric acid; poly-Metaphosphoric acid is the most volatile stable compound; have high dehydrated, at polymer table compound and air exclusion；The substantial amounts of heat of moisture sorption of abjection, makes polymer surfaces fire retardant decomposes discharge volatility phosphide.
Phos fire retardant and organophosphorous fire retardant can be divided into by the Nomenclature Composition and Structure of Complexes phosphorus flame retardant.Phos fire retardant is mainly based on red phosphorus, phosphate and phosphorus-nitrilo compound；Phos fire retardant can be used alone, it is possible to is used in conjunction with other fire retardants, but its during being used alone the easy moisture absorption, easily harden, therefore use be very limited.In order to improve its safety, stability, and improving the compatibility of itself and matrix resin, it is carried out surface processing is one of the Main way of research.Current research is concentrated mainly on the application aspect of red phosphorus, and wherein micro encapsulation is most efficient method.Such as inorganic coating method, organic coating method and inorganic-organic hybrid cladding process.Wherein compound coating method is to select suitable macromolecular material capsule material to be again coated with on the basis of inorganic coating red phosphorus, is presently the most preferable red phosphorus method of modifying.It not the most too many for ammonium di-hydrogen phosphate research in this respect.Research shows, flame retardance of polymer performance and mechanical property are had a great impact by the granularity of inorganic anti-flaming material.The fire retardant of equivalent, granularity is the least, and specific surface area is the biggest, and flame retardant effect is the best.Organic phosphorus flame retardant has fire-retardant and plasticising double effects, mainly based on phosphate ester, phosphite ester and phosphonate ester.Additionally, the compound of the most multiple phosphorus substituent group, polymers etc..Phosphate ester aboundresources, cheap, it is the leading products in organic phosphorus flame retardant.
First the present invention is that the method by physics prepares ammonium di-hydrogen phosphate superfines, to reduce it；Granularity, increases specific surface area the biggest, improves flame retardant effect；The powder obtained is coated with, to prevent the moisture absorption, to harden with macromolecular material (universal resin) the most rapidly；Be to be blended with phosphate ester again, form inorganic-organic phosphate ester composite fire proofing, finally adding a little polyalcohols, increase in material point between hydrogen bond, lower sedimentation；Can also add a certain amount of aluminium hydroxide, it passes through intermolecular interaction simultaneously, forms space structure, can reduce the sedimentation of material, the most also in the case of keeping resins fire retardant effect, is greatly enhanced flame retardant effect.
In common resins for universal use, the aluminium hydroxide adding more than 120 parts just can make the limited oxygen index of resin reach 32-34；Add 100 parts and can reach 28-30；But the number owing to adding is more, reduce the construction effect of resin, greatly reduce the mechanical property of resin simultaneously, as a example by the fracture elongation of pour mass (before adding, clear resin fracture elongation percentage is 2.4%), after adding 120 parts, rarely exceed 1.2%；Add 100 parts and seldom have more than 1.5%.And this composite, it is only necessary to add 60 parts, it is possible to reach capacity oxygen index (OI) 34, add 50 parts and can keep limited oxygen index more than 31.Owing to addition is few, the workability of the resin obtained is good, and less owing to adding number, and resin mechanical property reduces little, and its fracture elongation is maintained at more than 2.0%.
Summary of the invention
It is an object of the invention to provide a kind of method by physics with chemistry, inorganic and organophosphorus ester are combined the inorganic-organic phosphate ester composite fire proofing of formation, this composite has high flame retardant, low cigarette, low toxicity, the feature of non-corrosiveness gas generation, improves again the shortcoming that inorganic combustion inhibitor height addition has a strong impact on the physical and mechanical properties of material simultaneously.
