Description
Technical field
The present invention relates to high-performance high ferro, motor vehicle seat fabric preparation field, relate generally to a kind of inorganic component that adds and solve the method that phosphorous flame-retardant coated fabric moisture absorption is tacky.
Background technology
Motor-car, high ferro have that speed is fast and transport capacity strong, are affected less feature by surface state and weather conditions, and along with the development in epoch, motor-car has become as people and goes on a journey the indispensable vehicles.But in the environment that these spaces such as motor-car, high ferro are less, heavy losses such as just will necessarily bringing person property of catching fire once interior material.The bus interior textile such as motor-car, high ferro should have excellent anti-flammability and a flame-retarding power, and so just in case passenger vehicle catches fire, passenger just has the sufficient time and flees from the scene of a fire, thus ensures the safety of passenger.Give motor-car, high ferro inner decoration textile fabric fire resistance has two kinds of methods: one is to use fire resistance fibre, and two is that inner decoration facing is carried out flame-proof treatment.Research finds, the alone fire resistance fibre of exploitation is not met by motor-car, the flame-retardancy requirements of high ferro inner decoration facing at present, it is necessary to do flame-proof treatment to improve fire resistance further.Therefore, research motor-car, the arrangement of high ferro inner decoration textile fabric high-performance refractory are necessary and meaning.
Implementing high performance flame-proof treatment fire retardant is it is first necessary to consider.By fire retardant with by the relation of ignition resistant substrate, fire retardant can be divided into: addition type and response type.Addition type refers to, with other components in base material, chemical reaction does not occur, and is simply scattered in for physically in base material, is used for thermal plasticity high polymer；Response type refers to or as the monomer of high polymer, or participates in the chemical reaction of synthetic high polymer as auxiliary reagent, finally becomes the construction unit of high polymer, is used for thermosetting high polymers；By the kind of ignition-proof element, fire retardant is the most often divided into: halogen system, phosphorus system, nitrogen system, boron system, magnesium system, aluminium system, silicon system etc.；By the type of compound, then can be divided into mineral-type fire retardant, organic fire-retardant and organic and inorganic mixing fire retardant three kinds.
In current macromolecular material fire retardant, metal oxide and hydroxide are inexpensive nontoxic, but bad with the compatibility of material, can reduce the thermodynamic property of material.Halogenated flame retardant particularly brominated flame-retardant, although have good flame retardant effect, but it is big to there is, during they burnings, the amount of being fuming, and generates corrosivity, poisonous gas, produces the critical defects such as molten drop.And organic phosphorus compound shows preferable fire resistance, and produce less toxic gas and smog than halide-containing.
Phosphorus and phosphorus compound are used as fire retardant very early, obtain the most deep to its Flame Retardant Mechanism.In differential responses district, the risen fire retardation of phosphorus flame retardant can be divided into condensed phase gentle phase fire retardant mechanism.Mass-spectrometric technique research finds, phosphonium flame retardant PO when polymer combustion is formed, can be as a kind of gaseous phase free radical capturing agent, and the hydrogen atom in flame is combined, and plays the effect of suppression flame.
From combustion process; the realization of fire retardation substantially be exactly interference support combustion reaction one or more key elements, be mainly manifested in by fire retardant thermal decomposition absorbing and cooling temperature, formed non-flame resistant property protection barrier film carry out covering, catching free radical, suppress or dilute imflammable gas etc..General fire retardant mechanism is divided into gas phase fire retardant mechanism, condensed phase fire retardant mechanism and interrupts heat exchange fire retardant mechanism.Fire retardant can make burning delay in the gas phase or interrupt looping combustion reaction, thus plays fire-retardant effect.Undoubtedly, fire-retardant is a process the most complicated, and in most cases, the realization of flame retardant effect is the multiple coefficient result of fire-retardant pattern, can not be well-separated, and the fire retardation of condensed phase and gas phase often influences each other.
The fire retardation of phosphorus flame retardant is mainly reflected in the high polymer catabolic phase of Initial Stage of Fire, and phosphorus compound decomposable asymmetric choice net generates the noninflammability liquid film of phosphoric acid, and boiling point is up to 300 DEG C.Phosphoric acid can be dehydrated generation metaphosphoric acid, and metaphosphoric acid is polymerized the poly-metaphosphoric acid of generation further.In this process, the cover layer that phosphoric acid dehydration carbonization effect generates plays blanketing effect, and isolation air diffuses and penetrate into inside combustible substance, thus changes the pattern of polymer combustion；It addition, the moisture that phosphorus flame retardant dehydration carbonization produces, on the one hand can reduce the temperature of condensed phase, on the other hand can dilute combustible concentration in gas phase, thus preferably play fire retardation.
But, because cyclic phosphate ester compounds itself does not has crosslinkable active group, even if addition crosslinking agent is not easy to control its moisture absorption and " oozes out " satiny tendency.And there is hot sticky drawback in the polyacrylate dispersion of the film-forming being frequently used in coating is processed.Therefore the flame-retardant coatings glue that fire retardant based on annular phosphate, polyacrylate dispersion are adhesive, after cured, the satiny feel of potential wetting can be there is.
Matte seat-cover fabric Flame-retardant gum coating is to confer to an important means of its fire resistance.Flame retardant coating arrangement experience is worked in coordination with phosphorus halogen from halogen antimony and is worked in coordination with, then arranges to halogen-free expandable cooperative flame retardant.Along with the raising of people's environmental consciousness, the progressively disabling of halogen flame, the application of phosphorus flame retardant seems more and more important, but this based flame retardant is also faced with the shortcomings such as the highest, the poor water resistance of flame retarding efficiency；In actual application, there is coating and moisten tacky defect.Therefore, improve flame retarding efficiency and the resistance to water of phosphorus system expandable flame retardant coating, be the basic of its tacky defect of flame retardant coating moisture absorption of solution.
Summary of the invention
In order to solve terylene matte seat fabric flame retardant rating and the tacky problem of moisture absorption, the invention provides a kind of inorganic component that adds and solve the method that phosphorous flame-retardant coated fabric moisture absorption is tacky.The present invention is tacky to solve phosphorous flame-retardant coating fabric moisture absorption by adding inorganic fire-retarded synergist, and then eliminate the contradictory relation between flame retarding efficiency and the feel of phosphorus system expandable flame retardant coating, to instruct motor-car, high ferro inner decoration facing, and the production of other draperies.
The technical scheme is that a kind of inorganic component that adds solves the method that phosphorous flame-retardant coated fabric moisture absorption is tacky, it is characterized in that, napping seat-cover fabric → coating is (by weight, acrylic acid ester emulsion consumption is 40～55%, phosphorus flame retardant consumption is 35～50%, inorganic fire-retarded synergist consumption 4～10%, thickener and water consumption 4～8%, pH value 5～6, the spread 200～260g/m of dacron2) → dry (80～100 DEG C, 1～3min) → bake (160～180 DEG C, 2～3min).
Wherein, the mixing of one or more during phosphorus flame retardant refers to APP, phosphate toluene diphenyl ester, triphenyl phosphate, IPPP, bisphenol-A-bis-(diphenyl phosphoesters), tricresyl phosphate, tricresyl phosphate (2-chloropropyl) ester, annular phosphate.
Wherein, one or more during inorganic fire-retarded synergist is zinc oxide, magnalium hydrotalcite, 4A zeolite, aluminium hydroxide.Preferably magnesium aluminum hydrotalcite.
Wherein, thickener is acrylic acid ester emulsion type thickener or polyacrylate emulsion type thickener LM-901.The consumption 0.5 of thickener～2% (thickener and water inventory 4～8%), preferably 0.5-1.0%.
During the dacron of phosphorous flame-retardant coating uses, produce the satiny tacky problem of feel.Currently mainly there are three kinds of theoretical explanations:
1. surface chemistry is theoretical: bibulous plane of crystal all has higher surface energy, and after it absorbs moisture in air, its high energy surface has reformed into low-energy surface, so the hygroscopicity of crystal to be solved, it is critical only that its surface texture of change, drop low-surface-energy, improve hydrophobicity.
2. crystal bridging theory: due to self property and the change of external condition, moisture constantly spreads (or because of surface moisture absorption) from inside to grain table, promote particle surface to dissolve, recrystallize, thus at particulate interspaces, form crystal build bridge, As time goes on, these brilliant bridges are combined with each other each other, gradually form big agglomerate.And this agglomerate should be the external manifestation of particle moisture absorption.Self property includes the physical dimension of crystalline nature, chemical composition, granularity, size distribution, crystal；External condition includes the factor such as humidity, temperature and pressure.
3. capillary absorption is theoretical: has hygroscopic material and absorbs moisture content more than its critical relative moisture, at the saturated solution film that plane of crystal is formed, accelerate capillary absorption, water saturation vapour pressure on capillary meniscus is less than outside saturated vapour pressure, external water steam diffuses between particle, thus moisture absorption deliquescence.
The ester exchange synthesis technique of annular phosphate produces the phosphoric acid oh group of hydrolysis moisture absorption, have be similar to phosphoric acid can the moisture absorption general character.And acid condition can be catalyzed cyclic phosphate ester hydrolysis, cause flame-retardant system moisture absorption more serious.In view of the understanding of above-mentioned theory, further specify that APP problem in the presence of application process, and provide direction for solution problem.
A.R.HORROCKS seminar is found by the research of antimony flame-retardant system back coating bromo-to textile, and its gas phase flame retardant activity is the key factor playing highly effective flame-retardant efficiency.On this basis, they propose the problem that three kinds of schemes solve the halogen flame of phosphonium flame retardant replacement now: one is flame retarding efficiency or the sensitiveness of decomposition temperature strengthening phosphorous flame-retardant system；Two is the dissolubility reducing DDGS system；Three are introduced into having volatility or potential gas phase volatile phosphorous flame-retardant component.
In view of the first scheme, it is by APP and slaine (Zn that domestic and international researcher applies more2+、Mn2+、Fe2+/Fe3+、Cu2+) compound.The MnSO of 2% (w/w)4/ polyphosphoric acid is reduced to 283 DEG C by the temperature of initial decomposition that can make it from 304 DEG C.The reduction of incipient degradation temperature can make the polyphosphoric acid of liquid from the back side diffusion to fabric face, stops the thermal degradation of surface fiber, the HPO of thermal decomposition.Can play gas phase fire retardation, free chain reaction mechanism is as follows:
HPO+H→PO+H2O
Phosphorus during Babushok et al. research discovery gas phase is fire-retardant than halogen more more effectively, selects have volatilization or potential volatile phosphorus-containing compound is formulated in flame retardant coating formula, be then necessary；And the temperature of initial decomposition that suitably reduces phosphorus-containing compound is the most significant.
First scheme being reduced to the solubility of DDGS, on the one hand domestic and international researcher is engaged in the cladding work of fire retardant, by flame retardant microcapsule；On the other hand, utilize in-situ chemical reaction thought, by fire-retardant stromal surface with internal chemical reaction occurs, it is low that its product has dissolubility, the feature that hygroscopicity is little.In fire-retarding of wood field, for solving the defect of timber hygroscopic deformation, successively impregnating into wood internal by vacuum pressed equipment by two kinds of solvable finishing functions liquid, the different parts generation chemical reaction at timber generates low aqueous solubility flame-retardant compound, reduces the purpose of fire-retardant, moisture-absorbing.
The third scheme relevant, researcher finds that phosphorus flame retardant plays a significant role in fabric durable is fire-retardant.The research such as A.R.HORROCKS finds that TBP is i.e. having obvious weightlessness less than 150 DEG C of polypropylene (fusing point 150 DEG C) and bafta (burning-point 350 DEG C), has facilitation to fire-retardant, thus has certain fire retardation；Later stage research finds that the appropriate TBP of interpolation can reduce shape phosphate (Antiblaze CU) and be applied to the defect that fire-retardant back coating is tacky, has certain resistance to water simultaneously.
Original expandable flame retardant coating process is with APP (acid source), and the flame-retardant system of the compounding polyacrylate (binder) of pentaerythrite (charcoal source), melamine (source of the gas) is applied to fabric fire-retardant finishing.But the addition of these materials is generally large, and resistance to water is poor；After arrangement, feel is harder, fabric face be susceptible to moisture absorption, tacky, whiten, return frost etc. phenomenon.Its reason is: when the steam partial pressure in outside air is more than coating surface steam partial pressure when, and the steam in air can assemble condensation at coating surface, and the hygroscopicity of fire retardant then accelerates the moisture scattering and permeating to glued membrane.The aqueous solution plasticising swelling to glued membrane of local, causes the hydrogen bond of glued membrane and Van der Waals force to be destroyed, defines the polyacrylate height concentrated solution containing fire retardant.The existence of the polar group on polymer and flame retardant molecule so that it is the contactant surface coarse to polarity produces cementation.
Thus, crystal bridging theory theoretical by surface chemistry and capillary absorption are theoretical to APP moisture absorption, the defect analysis of returning frost, and the present invention proposes to add appropriate inorganic combustion inhibitor to improve the problem that phosphorus flame retardant application produces.Take into account different characteristics and the performance of fire retardant, organic and inorganic fire retardant Synergistic is used, the kind of optimum choice fire retardant simultaneously, and then reduce its consumption, improve moisture absorption with this and return the defect of frost.
The advantage of this patent is:
(1) phosphorus of the present invention-inorganic combustion inhibitor principle and advantage
Phosphorous flame-retardant mechanism: one be have high dehydrated, generation phosphoric acid during phosphorus flame retardant high-temp combustion or polyphosphoric acid, easily form full-bodied melten glass matter and fine and close charring layer on comburant surface, make textile completely cut off with heat and oxygen and come；Two is capture free radical, decomposes free radicals such as generating PO or HPO in burning, catches activity H free radical or OH free radical under gas phase state；Three is the foaming charring layer promoting comburant surface to form Porous, cuts off heat and oxygen；Three aspects are incorporated into row, jointly produce flame retardant effect.
Inorganic fire-retarded synergist fire retardant mechanism: inorganic component can be absorbed the produced heat of a large amount of burning by thermal decomposition process, causes the temperature of burner body to be down to below burning critical-temperature, fray-out of flame；Decompose the metal oxide generated or other melting point compound is high, Heat stability is good, heat transfer and heat radiation can be stopped when being covered in burner body surface；Part inorganic combustion inhibitor can decompose the big steam of generation, with dilution oxygen and inflammable substance, thus reaches fire-retardant purpose.
When phosphorus-inorganic combustion inhibitor uses, when high-temp combustion, phosphorus system, inorganic compound the most each play the fire resistance of self, influence each other simultaneously, mutually promote so that flame retardant effect performs to most preferably.Under high temperature, phosphorus can be catalyzed the formation facilitating charcoal, covers on combustible gas, completely cuts off air, and inorganic component decomposites the product that can dilute oxygen and imflammable gas, and reduces the temperature of combustible gas, makes reaction terminating；Meanwhile, metal oxide covering can stop heat transfer and heat radiation, can stop the oxidation of layer of charcoal further, strengthen the heat endurance of these layer of charcoal, so that flameout；Additionally, inorganic component by thermal decomposition can by textile combustion time the partial heat that produces take away so that it is heat decomposition temperature can not be maintained, thus lasting fuel gas can not be produced, and then play phosphorus/inorganic component cooperative flame retardant effect；Obviously, in this patent, phosphorus-inorganic combustion inhibitor is compounding when using, and the two fire-resistant synergistic effect is far from the effect superposition in simple meaning, but Synergistic.
(2) inorganic combustion inhibitor Synergistic advantage of the present invention
Phosphorus flame retardant can absorb moisture in air and dissolves, making the phosphorus flame retardant in portion in coating adhesive body gradually dissolve, when the steam of absorption can not be discharged in time, saturated vapor starts to condense at particle surface, dissolve part phosphorus flame retardant particle top layer, form phosphorus flame retardant saturated solution.Along with temperature raises, solubility increases, dissolve saturated solution viscosity to increase, powder becomes viscous liquid, dissolving and heat absorbing and persistently carrying out, and causes system temperature to decline, saturated phosphorous flame-retardant agent solution starts to separate out crystallization, constantly reducing with temperature, part phosphorus flame retardant crystal persistently separates out, and produces " frost is returned in whiting " phenomenon of coating surface immediately.
Use for reference the achievement in research of the hydrolysising aging of fire retardant, ester exchange principle in conjunction with ring-type phosphate synthesis technique, the present invention proposes to add in metal oxide synergist and the acidic materials of fire retardant, close the polar hygroscopic group of fire retardant, on the premise of not changing fire retardant permeability, reduce its precipitation, performance of moisture absorption.
For avoiding acrylate coatings glue hot sticky cold crisp, and the defect that its film forming is affected by fire retardant, the present invention proposes to introduce metal oxide synergist and strengthens the compatibility between phosphorus flame retardant and acrylic acid ester emulsion, strengthens the crosslinking degree of coating adhesive, and improves the feel problem of coating.Meanwhile, the increase of chemical crosslinking degree, char forming ability when improve burning, closely knit layer of charcoal can be closed the effusion of imflammable gas and reduce the heat radiation of flame；The gas foaming closed expands and produces pore, and the intumescent layer of charcoal of formation reduces heat transfer, makes flame conduction reduce further to the heat of burning transition region, thus reduces the intensity of a fire.
(3) this patent coated fabric performance advantage
It has been investigated that: inorganic fire-retarded synergist decreases the consumption of phosphorus flame retardant；Further, controlling spread, up to preferable fire resistance, the surface of the most original phosphorus system is returned the defects such as frost, feel be satiny and tacky and is substantially improved；It addition, control the concentration of flame-retardant coatings glue and denseness so that gum just right through the back side to matte, sufficiently achieve good flame resistance, matte style is unaffected, and wearability and many-sided effect of excellent durability.
(3) other advantages of this patent
This patent solves, by adding inorganic fire-retarded synergist, the method ecological, environmental protective that the coated fabric moisture absorption of phosphorus system is tacky, safe and efficient, simple and easy to do, with low cost, complying with industry development trend, after large-scale industrial production, profit margin is considerable, and this is also that the characteristic of this patent is one of creative.
