Description
Technical field
The present invention relates to high-performance high ferro, motor vehicle seat fabric preparation field, relates generally to a kind of addition inorganic component solution
The certainly tacky method of phosphorous flame-retardant coated fabric moisture absorption.
Background technology
Motor-car, high ferro have speed fast and transport capacity is strong, are influenced less feature by surface state and weather conditions, with
The development in epoch, motor-car has become the indispensable vehicles of people's trip.But these are opposite in motor-car, high ferro etc.
In the less environment in space, the heavy losses such as personal property will necessarily be brought once interior material catches fire.The visitors such as motor-car, high ferro
In-car decorations textile should have excellent anti-flammability and flame-retarding power, and so just in case car catches fire, passenger just has sufficiently
Time flees from the scene of a fire, so as to ensure the safety of passenger.Assign motor-car, high ferro inner decoration textile fabric fire resistance there are two methods：One
It is to use fire resistance fibre, second, carrying out flame-proof treatment to inner decoration facing.Research finds that the alone fire resistance fibre developed at present is also not
It can meet motor-car, the flame-retardancy requirements of high ferro inner decoration facing, it is necessary to do flame-proof treatment to further improve fire resistance.Therefore,
Study motor-car, the arrangement of high ferro inner decoration textile fabric high-performance refractory is necessary and meaning.
Implement high performance flame-proof treatment fire retardant to must take into consideration first.By fire retardant and the pass by ignition resistant substrate
System, fire retardant can be divided into：Addition type and response type.Addition type refers to not chemically react with the other components in base material, only
It is to be scattered in for physically in base material, is chiefly used in thermal plasticity high polymer；Response type refers to or the monomer as high polymer, or
Person participates in the chemical reaction of synthetic high polymer as auxiliary reagent, finally as the construction unit of high polymer, is chiefly used in thermosetting
Property high polymer；By the species of ignition-proof element, fire retardant is generally often divided into：Halogen system, phosphorus system, nitrogen system, boron system, magnesium system, aluminium system, silicon systems
Deng；By the type of compound, then it can be divided into inorganic based flame retardant, organic fire-retardant and organic and inorganic three kinds of fire retardant of mixing.
In current high molecular material fire retardant, metal oxide and hydroxide are inexpensive nontoxic, but with the compatibility of material
It is bad, the thermodynamic property of material can be reduced.Halogenated flame retardant particularly brominated flame-retardant, although there is good flame retardant effect,
But there are smoke amount is big when they burn, generation corrosivity, poisonous gas, produce the critical defects such as molten drop.And organophosphor chemical combination
Thing shows preferable fire resistance, and less toxic gas and smog are produced than halide-containing.
Phosphorus and phosphorus compound are used as fire retardant very early, its Flame Retardant Mechanism are obtained also more deep.
In differential responses area, phosphorus flame retardant, which plays fire retardation, can be divided into the gentle phase fire retardant mechanism of condensed phase.Mass-spectrometric technique research is sent out
Existing, phosphonium flame retardant PO in polymer combustion is formed, and can be used as a kind of gaseous phase free radical capturing agent, former with the hydrogen in flame
Son combines, and plays the role of suppressing flame.
From combustion process, the realization of fire retardation is substantially exactly that interference supports that the one or more of combustion reaction will
Element, be mainly manifested in by fire retardant thermally decompose absorbing and cooling temperature, formed non-flame resistant property protect membrane to be covered, be captured from by
Base, suppression or dilution 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 or interrupt looping combustion to react in the gas phase, so as to play fire-retardant effect.
Undoubtedly, fire-retardant is a very complicated process, and in most cases, the realization of flame retardant effect is that a variety of fire-retardant patterns are total to
Same-action as a result, can not be well-separated, 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, phosphorus compound decomposable asymmetric choice net
The noninflammability liquid film of phosphoric acid is generated, boiling point is up to 300 DEG C.Phosphoric acid can be dehydrated generation metaphosphoric acid, and metaphosphoric acid further polymerize life
Into poly-metaphosphoric acid.In this process, the coating of phosphoric acid dehydration carbonization effect generation plays blanketing effect, isolation air diffusion
Penetrate into inside combustible substance, so as to change the pattern of polymer combustion；In addition, the water that phosphorus flame retardant dehydration carbonization produces
Point, the temperature of condensed phase on the one hand can be reduced, on the other hand can dilute combustible concentration in gas phase, so as to preferably rise
To fire retardation.
However, because cyclic phosphate ester compounds are in itself without crosslinkable active group, it is not easy to even if adding crosslinking agent
Control the satiny tendency of its moisture absorption " exudation ".And the polyacrylate dispersion of the film-forming usually used in coating processing is deposited
Hot sticky the drawbacks of.Therefore the fire retardant, polyacrylate dispersion based on annular phosphate are the flame-retardant coatings glue of adhesive,
After cured, can exist and potentially soak satiny feel.
Matte seat-cover fabric Flame-retardant gum coating is to confer to an important means of its fire resistance.Flame retardant coating arranges warp
Go through and cooperateed with from the collaboration of halogen antimony to phosphorus halogen, then arranged to halogen-free expandable cooperative flame retardant.With the improvement of people's environmental awareness, halogen hinders
Fire the progressively disabling of agent, the application of phosphorus flame retardant seems more and more important, but this based flame retardant be also faced with flame retarding efficiency it is not high,
The shortcomings of poor water resistance；In actual application, there are coating to moisten the defects of tacky.Therefore, phosphorus system expandable flame retardant is improved to apply
Layer flame retarding efficiency and water resistance, be solve its tacky defect of flame retardant coating moisture absorption it is basic.
The content of the invention
In order to solve the problems, such as that terylene matte seat fabric flame retardant rating and moisture absorption are tacky, the present invention provides one kind to add
Inorganic component solves the tacky method of phosphorous flame-retardant coated fabric moisture absorption.The present invention is by adding inorganic fire-retarded synergist to solve
Phosphorous flame-retardant coating fabric moisture absorption is tacky, and then the contradiction eliminated between the flame retarding efficiency of phosphorus system expandable flame retardant coating and feel is closed
System, 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 tacky side of phosphorous flame-retardant coated fabric moisture absorption
Method, it is characterized in that, (by weight, acrylic acid ester emulsion dosage is 40~55% to raising seat-cover fabric → coating, phosphorus flame retardant
Dosage is 35~50%, inorganic fire-retarded synergist dosage 4~10%, and thickener and water consumption 4~8%, pH value 5~6, terylene is knitted
200~260g/m of spread of thing2) → drying (80~100 DEG C, 1~3min) → bake (160~180 DEG C, 2~3min).
Wherein, phosphorus flame retardant refer to ammonium polyphosphate, phosphate toluene diphenyl ester, triphenyl phosphate, triisopropyl phenyl phosphate,
Bisphenol-A-bis- (diphenyl phosphoester), tricresyl phosphate, tricresyl phosphate (2- chloropropyls) ester, one kind in annular phosphate or more
The mixing of kind.
Wherein, inorganic fire-retarded synergist is the one or more in zinc oxide, magnalium hydrotalcite, 4A zeolites, aluminium hydroxide.
It is preferred that magnalium hydrotalcite.
Wherein, thickener is acrylic acid ester emulsion type thickener or polyacrylate emulsion type thickener LM-901.Thickener
Dosage 0.5~2% (thickener and water inventory 4~8%), preferably 0.5-1.0%.
During the dacron use of phosphorous flame-retardant coating, the problem of feel is satiny tacky is produced.Mainly have at present
Three kinds of theoretical explanations：
1. surface chemistry is theoretical：Bibulous plane of crystal has higher surface energy, when it absorbs moisture in air
Afterwards, its high energy surface has reformed into low-energy surface, so to solve the hygroscopicity of crystal, key is to change its surface texture,
Surface energy is reduced, improves hydrophobicity.
2. crystal bridging theory：Due to the change of self property and external condition, moisture is spread constantly from inside to grain table
(or because of surface moisture absorption), promotes particle surface dissolving, recrystallization, builds bridge so as to form crystal at particulate interspaces, with the time
Passage, these crystal briges each other be combined with each other, gradually form big agglomerate.And this agglomerate should be the external of particle moisture absorption
Performance.Self property includes crystalline nature, chemical composition, granularity, size distribution, the physical dimension of crystal；External condition includes
The factors such as humidity, temperature and pressure.
3. capillary absorption is theoretical：Moisture content is absorbed more than its critical relative moisture with hygroscopic material, in crystal table
The saturated solution film that face is formed, accelerates capillary absorption, and the saturated vapour pressure of the water on capillary meniscus is full less than exterior
And vapour pressure, exterior vapor are diffused between particle, so that moisture absorption deliquescence.
The ester exchange synthesis technique of annular phosphate produces the phosphoric acid hydroxyl group of hydrolysis moisture absorption, has 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.It is in view of above-mentioned
Theoretical understanding, further specify that ammonium polyphosphate in the presence of application process the problem of, and to solve the problems, such as to provide
Direction.
A.R.HORROCKS seminars pass through the research discovery to the bromo- antimony flame-retardant system back coating of textile, its gas phase
Flame retardant activity is to play the key factor of highly effective flame-retardant efficiency.On this basis, they propose three kinds of schemes to solve to contain now
Phosphorus fire retardant substitutes the problem of halogen flame：First, the flame retarding efficiency of enhancing phosphorous flame-retardant system either decomposition temperature is quick
Perception；Second, reduce the dissolubility of solvable objects system；Third, introducing has volatility or the volatile phosphorous flame-retardant of potential gas phase
Component.
In view of the first scheme, domestic and international researcher using it is more be by ammonium polyphosphate and metal salt (Zn2+、Mn2+、Fe2 +/Fe3+、Cu2+) compound.The MnSO of 2% (w/w)4/ polyphosphoric acid is reduced to 283 by can make its temperature of initial decomposition from 304 DEG C
℃.The reduction of incipient degradation temperature can make the polyphosphoric acid of liquid prevent surface fiber from the back side diffusion to fabric face
Thermal degradation, the HPO of thermal decomposition.Gas phase fire retardation can be played, free chain reaction mechanism is as follows：
HPO+H→PO+H2O
Phosphorus during Babushok et al. research discovery gas phases are fire-retardant is more more effective than halogen, and selection is with volatilization or latent
It is formulated in volatile phosphorus-containing compound in flame retardant coating formula, then is necessary；And suitably reduce phosphorus-containing compound
Temperature of initial decomposition it is also significant.
The solubility of soluble matter is reduced for second scheme, on the one hand domestic and international researcher is engaged in the cladding work of fire retardant
Make, by flame retardant microcapsule；On the other hand, using the thought of in-situ chemical reaction, by fire-retardant stromal surface and inside
Chemically react, its product has the characteristics of dissolubility is low, and hygroscopicity is small.In fire-retarding of wood field, inhaled to solve timber
The defects of green deformation, two kinds of solvable finishing functions liquid are successively impregnated into wood internal by vacuum pressed equipment, in timber
Chemical reaction generation low aqueous solubility flame-retardant compound occurs for different parts, achievees the purpose that to reduce fire-retardant, moisture-absorbing.
The third related scheme, researcher have found that phosphorus flame retardant plays a significant role in fabric durable is fire-retardant.
The researchs such as A.R.HORROCKS find that TBP is in 150 DEG C less than polypropylene (150 DEG C of fusing point) and cotton fabric (350 DEG C of burning point)
There is obvious weightlessness, have facilitation to fire-retardant, thus there is certain fire retardation；Later stage research finds to add suitable TBP
Shape phosphate (Antiblaze CU) can be reduced and be applied to the defects of fire-retardant back coating is tacky, while there is certain water resistance.
Original expandable flame retardant coating process is with ammonium polyphosphate (acid source), pentaerythrite (charcoal source), melamine (gas
Source) compounding polyacrylate (binder) flame-retardant system be applied to fabric fire-retardant finishing.But the additive amount of these materials is general
It is larger, and water resistance is poor；Feel is harder after arrangement, fabric face easily occur moisture absorption, it is tacky, whiten, return phenomena such as frost.
The reason is that：When the steam partial pressure in outside air is more than coating surface steam partial pressure, the vapor in air
It can assemble in coating surface and condense, and the hygroscopicity of fire retardant then accelerates scattering and permeating of the moisture to glued membrane.Local is water-soluble
Liquid is swollen glued membrane and is plasticized, and the hydrogen bond and Van der Waals force for causing glued membrane are destroyed, and form the polyacrylate containing fire retardant
Height concentrated solution.The presence of polar group on polymer and flame retardant molecule, produces its contactant surface coarse to polarity
Raw cementation.
Thus, by surface chemistry is theoretical, crystal bridging theory and capillary absorption theory to ammonium polyphosphate moisture absorption, return frost
Defect analysis, the present invention propose to add appropriate inorganic combustion inhibitor to improve the problem of phosphorus flame retardant application produces.Take into account fire-retardant
The different characteristics and performance of agent, organic and inorganic fire retardant synergy is used, while the species of optimum choice fire retardant, into
And its dosage is reduced, the defects of frost is returned in moisture absorption is improved with this.
The advantage of this patent is：
(1) phosphorus of the present invention-inorganic combustion inhibitor principle and advantage
Phosphorous flame-retardant mechanism：First, there is high dehydrated, generation phosphoric acid or polyphosphoric acid during phosphorus flame retardant high-temp combustion,
Highly viscous melten glass matter and fine and close charring layer are easily formed on comburant surface, textile is opened with heat and oxygen isolation
Come；Second, capture free radical, decomposes the free radicals such as generation PO or HPO, activity H is caught under gas phase state in burning
Free radical or OH free radicals；Third, promoting comburant surface to form the foaming charring layer of Porous, separate heat and oxygen；Three aspects
With reference to progress, flame retardant effect is produced jointly.
Inorganic fire-retarded synergist fire retardant mechanism：Inorganic component can be absorbed heat caused by a large amount of burnings by thermal decomposition process
Amount, causes the temperature of burner body to be down to below burning critical-temperature, fray-out of flame；Decompose the metal oxide or otherization of generation
Compound fusing point is high, heat endurance is good, can stop heat transfer and heat radiation when being covered in burner body surface；Part inorganic combustion inhibitor
It can decompose and produce big vapor, with dilution oxygen and inflammable substance, so as to achieve the purpose that fire-retardant.
When phosphorus-inorganic combustion inhibitor in use, in high-temp combustion, phosphorus system, inorganic compound not only each play itself
Fire resistance, influences each other at the same time, mutually promotes so that flame retardant effect performs to most preferably.Under high temperature, phosphorus, which can be catalyzed, facilitates charcoal
Formed, be covered on combustible gas, completely cut off air, and inorganic component decomposites the product that can dilute oxygen and imflammable gas, and drop
The temperature of low combustible gas, makes reaction terminating；, can be into one meanwhile metal oxide covering can stop heat transfer and heat radiation
Step prevents the oxidation of layer of charcoal, strengthens the heat endurance of these layer of charcoal, so that flameout；In addition, inorganic component is thermally decomposed
Partial heat caused by textile combustion can be taken away, prevent it from maintaining heat decomposition temperature, so as to cannot produce lasting
Fuel gas, and then play phosphorus/inorganic component cooperative flame retardant effect；Obviously, phosphorus-inorganic combustion inhibitor compounding use in this patent
When, the two fire-resistant synergistic effect is far from the effect superposition in simple meaning, but synergistic.
(2) inorganic combustion inhibitor synergy advantage of the present invention
Phosphorus flame retardant can absorb moisture in air and dissolves, and the phosphorus flame retardant inside coating adhesive body is gradually dissolved,
When the vapor of absorption cannot discharge in time, saturated vapor starts to condense in particle surface, dissolves part phosphorous flame-retardant
Agent particle top layer, forms phosphorus flame retardant saturated solution.As temperature raises, solubility increase, the fluid viscosity increase of dissolving saturation,
Powder is changed into viscous liquid, dissolving and heat absorbing and lasting progress, causes system temperature to decline, and saturation phosphorous flame-retardant agent solution starts to analyse
Go out crystallization, constantly reduced with temperature, part phosphorus flame retardant crystal persistently separates out, and produces immediately " frost is returned in whiting " of coating surface
Phenomenon.
The achievement in research of the hydrolysising aging of fire retardant is used for reference, with reference to the ester exchange principle of ring-type phosphate synthesis technique,
The present invention proposes the acidic materials with fire retardant in addition metal oxide synergist, closes the polar hygroscopic group of fire retardant,
Do not change fire retardant it is infiltrative under the premise of, reduce its separate out, the performance of moisture absorption.
To avoid acrylate coatings glue hot sticky cold crisp, and the defects of its film forming is influenced by fire retardant, the present invention proposes
The compatibility between metal oxide synergist reinforcement phosphorus flame retardant and acrylic acid ester emulsion is introduced, strengthens the crosslinking of coating adhesive
Degree, and improve the feel problem of coating.Meanwhile the increase of degree of chemical crosslinking, char forming ability when improving burning, closely knit charcoal
Layer can close the effusion of imflammable gas and reduce the heat radiation of flame；The gas foaming expansion of closing produces stomata, is formed
Intumescent layer of charcoal reduce heat transfer, make flame conduct to burning transition region heat further reduce, so as to reduce the intensity of a fire.
(3) this patent coated fabric performance advantage
It has been investigated that：Inorganic fire-retarded synergist reduces the dosage of phosphorus flame retardant；Also, spread is controlled, it is reachable
Preferable fire resistance, while the surface of original phosphorus system is returned the defects of white, feel is satiny and tacky and is substantially improved；In addition, control
The concentration and denseness of flame-retardant coatings glue, so that the just right back side that passes through of gum sufficiently achieves good flame resistance, matte wind to matte
Lattice are unaffected, and many-sided effect of wearability and excellent durability.
(3) other advantages of this patent
This patent solves the tacky method ecological, environmental protective of phosphorus system coated fabric moisture absorption, peace by adding inorganic fire-retarded synergist
Overall height is imitated, simple and easy to do, of low cost, complies with industry development trend, profit margin is considerable after large-scale industrial production, this is also
One of characteristic creativeness of this patent.
