Inventor's influence in the course of the study to the composition in ABS bittern-free flame-proof material prescriptions to material combustion performance
Investigated：
(1) influences of the nano-CG-ATH to fire proofing combustibility
The amount of fixed ERP is the 15% of total amount.
Influences of the table 1nano-CG-ATH to fire proofing combustibility
Note：The consumption of nano-CG-ATH is that it accounts for tri- kinds of percentages of material gross weight of ABS, ERP and nano-CG-ATH.
As it can be seen from table 1 when 15% encapsulated red phosphorus are only added during the consumption of nano-CG-ATH is for 0, ABS, it is fire-retardant
The horizontal firing grade of material is FH-2 grades, and after 3% nano-CG-ATH is added, the horizontal firing grade of fire proofing reaches
Arrived horizontal firing highest FH-1 grades.Afterwards, with the increase of nano-CG-ATH consumptions, the horizontal firing of fire proofing
Grade is always maintained at highest FH-1 grades of horizontal firing.It can also be seen that when the cladding that 15% is only added in ABS is red from table
During phosphorus, the combustibility of composite does not reach the judgment criteria of vertical combustion；As nano- in ABS/ encapsulated red phosphorus fire proofings
When the consumption of CG-ATH is equal to or less than 6%, the combustibility of fire proofing can not still meet the judgment criteria of vertical combustion；
When the consumption of nano-CG-ATH reaches 9%, the combustibility of fire proofing reaches the judgment criteria of vertical combustion, is FV-1 grades,
When the consumption of nano-CG-ATH is 15%, the combustibility of fire proofing reaches highest FV-0 grades of vertical combustion.By the above
Analysis understands that, with the increase of nano-CG-ATH consumptions, the fire resistance of fire proofing shows increased trend.
(2) influences of the nano-CG-ATH to fire proofing mechanical property
Nano-CG-ATH consumptions to the influence curve figure of fire proofing impact strength and tensile strength as shown in Figure 1.
From accompanying drawing 1, with the increase of nano-CG-ATH consumptions, the impact strength of fire proofing constantly declines.When
Nano-CG-ATH consumptions from 0 increase to 15% when, impact strength is from 10.54kJ/m2Drop to 5.92kJ/m2, fall reaches
43.83%.Elastic body toughening is that rubber grain induces matrix shear yielding and crazing, plasticity energy is absorbed, to matrix material
Toughness does not have particular/special requirement.Rigid inorganic filler toughening is different from elastic body toughening, and its toughening mechanism is：Rigid particles are added
Afterwards as stress concentration point, trigger substantial amounts of crazing, when its consumption reaches critical value, the violent interaction between stress field promotees
Make base material that surrender and plastic deformation and energy absorption to occur, this requires the base material ability with plastic deformation in itself, that is, require
Base material has certain toughness.In the present invention, due to base material (herein base material be ABS, ERP, as shown in Figure 1) toughness it is poor,
Impact strength only has 10.54kJ/m2, so the addition of nano-CG-ATH will not increase the toughness of base material, conversely, with it
The toughness of the increase base material of consumption can worse and worse, so as to the impact strength for causing fire proofing constantly declines.Therefore, ensureing
On the premise of the fire resistance of fire proofing reaches requirement, the addition of nano-CG-ATH is more few better.
The tensile strength of fire proofing shows downward trend after first rising with the increase of nano-CG-ATH consumptions,
But amplitude of variation is little.When nano-CG-ATH consumptions are less than 3%, tensile strength constantly increases, and is used in nano-CG-ATH
Tensile strength reaches maximum when measuring as 3wt%, is 36.73MPa.Afterwards, with the increase of nano-CG-ATH consumptions, stretching is strong
Degree constantly declines, and when its consumption is 15%, tensile strength is reduced to 34.85MPa.It can be seen that, in the system, when addition is smaller
When, nano-CG-ATH has certain humidification to fire proofing.And after nano-CG-ATH consumptions exceed 3%, due to poly-
Dispersiveness is deteriorated in compound, and particle occurs diffusion phase transformation, is changed from microdomain to grand farmland, causes particle diameter to increase, agglomeration
Seriously, so as to introduce more defects in matrix material, in the presence of tensile stress, easily there is the sliding and increasing of dislocation
Grow, make the reduction of its mechanical property.
Influence of the nano-CG-ATH consumptions to fire proofing bending modulus is as shown in Figure 2.
From accompanying drawing 2, with the increase of nano-CG-ATH consumptions, the bending modulus of fire proofing is showed on significantly
The trend for rising.When nano-CG-ATH consumptions increase to 15% from 0, bending modulus increases to 2472MPa from 1830MPa, increases
Amplitude is up to 35.08%.As can be seen here, the addition of nano-CG-ATH contributes to the rigid increase of fire proofing.
(3) influence of the encapsulated red phosphorus to fire proofing combustibility
Red phosphorus is relatively suitably applied oxygen-containing high polymer, and not ideal to the flame retardant effect of polyolefin, it is necessary to hydrogen-oxygen
Change the fire retardant synergistic such as aluminium and magnesium hydroxide using can be only achieved preferable flame retardant effect.The present invention using encapsulated red phosphorus as
The synergistic flame retardant of nano-CG-ATH, achieves good flame retardant effect.
It is 15% to keep nano-CG-ATH consumptions, changes the consumption of encapsulated red phosphorus, investigates its change and fire proofing is burnt
The influence of performance, the results are shown in Table 2
Influence of the encapsulated red phosphorus of table 2 to fire proofing combustibility
Note：The consumption of encapsulated red phosphorus is that it accounts for tri- kinds of percentages of material gross weight of ABS, ERP and nano-CG-ATH.
From table 2 it can be seen that when 15% nano-CG-ATH is only added in ABS, the horizontal firing grade of fire proofing
It it is FH-4 grades, horizontal firing speed is 50.16mm/min；After 3% encapsulated red phosphorus are added, horizontal firing of fire proofing etc.
Level does not change, but its horizontal firing speed is reduced to 41.67mm/min；When in ABS/nano-CG-ATH fire proofings
When the consumption of encapsulated red phosphorus is 6%, the horizontal firing grade of fire proofing is changed into FH-3 grades from FH-4 grades, when the use of encapsulated red phosphorus
Measure for 9% when, the horizontal firing grade of fire proofing is still FH-3 grade, but its horizontal firing speed is by 35.71mm/min drops
It is 27.27mm/min；When the consumption of encapsulated red phosphorus is 12%, the horizontal firing grade of fire proofing has reached horizontal firing
Highest FH-1 grades, afterwards, with the increase of cladding consumption, the horizontal firing grade of fire proofing is always maintained at horizontal firing
It is highest FH-1 grades.From table it can also be seen that when 15% nano-CG-ATH is only added in ABS, the burning of composite
Performance does not reach the judgment criteria of vertical combustion；When encapsulated red phosphorus in ABS/nano-CG-ATH fire proofings consumption be equal to or
During less than 9%, the combustibility of fire proofing can not still meet the judgment criteria of vertical combustion；The consumption of encapsulated red phosphorus reaches
When 12%, the combustibility of fire proofing reaches the judgment criteria of vertical combustion, is FV-1 grades, and the consumption of encapsulated red phosphorus is 15%
When, the combustibility of fire proofing reaches highest FV-0 grades of vertical combustion.Analysis is not difficult to find out more than, with cladding
The increase of red phosphorus consumption, the fire resistance of fire proofing shows increased trend.
If only add nano-CG-ATH in ABS matrixes, its addition should at least reach 50% can just make ABS bases
The vertical combustion of fire proofing meets FV-0 grades of requirement.As can be seen here, have between encapsulated red phosphorus and nano-CG-ATH well
Synergistic flame retardant effect.
Red phosphorus generates phosphorous oxide when burning, the steam reaction that can be decomposed to give off with nano-CG-ATH, promotes nano-
The endothermic decomposition of CG-ATH, prevents the carrying out of burning.And the quickening of nano-CG-ATH decomposition rates is the reaction of generation phosphoric acid
There is provided enough water vapours, the formation speed of phosphoric acid is accelerated, phosphoric acid can further be dehydrated generation metaphosphoric acid, and then aggregate into
Poly-metaphosphoric acid glassy mass, the material is covered in polymer surfaces, plays a part of starvation and imflammable gas, so that
Effectively prevent the carrying out of burning.Therefore, red phosphorus has synergistic fire retardation with nano-CG-ATH.In addition, containing encapsulated red phosphorus
Fire proofing burn when, phosphorus therein is converted into phosphoric acid and poly-metaphosphoric acid, these highly acid material energy catalytic resins solidification
Thing into charcoal reaction, be conducive to its pyrolysis product to condense and carbonize into fire retardant graphite-like charcoal, phosphorus is during then major part residues in layer of charcoal.
This graphite-like layer of charcoal is fire retardant, heat-insulated, oxygen barrier, burning is suffocated, meanwhile, this layer of charcoal heat conductivility is poor, makes to be delivered to base material
Heat reduce, the thermal decomposition of base material slows down, so as to play condensed phase fire retardation.
(4) influence of the encapsulated red phosphorus to fire proofing mechanical property
Influence of the consumption of encapsulated red phosphorus to fire proofing impact strength and tensile strength is as shown in Figure 3.
From the figure 3, it may be seen that with the increase of encapsulated red phosphorus consumption, the impact strength of fire proofing drastically declines, when its consumption
When increasing to 15% from 0, the impact strength of fire proofing is from 15.10kJ/m2Drop to 5.92kJ/m2, fall is
60.79%.As can be seen here, the serious toughness for compromising fire proofing of the addition of encapsulated red phosphorus.To find out its cause, encapsulated red phosphorus with
The poor compatibility of ABS, its addition can make to produce numerous stress concentration point in ABS matrixes, under outer stress, boundary
Place easily peels off, also big because peeling off the hole for producing along with red phosphorus particle is thick, so as to trigger crack, causes the crisp of material
Property fracture.
With the increase of encapsulated red phosphorus consumption, the tensile strength of fire proofing first rises and declines afterwards.When encapsulated red phosphorus consumption
During less than 9%, tensile strength constantly increases, and when encapsulated red phosphorus consumption is 9%, tensile strength reaches maximum, is 35.65MPa.
Afterwards, with the increase of encapsulated red phosphorus consumption, tensile strength constantly declines, and when its consumption is 15%, tensile strength is reduced to
34.85MPa.It can be seen that, in the system, when addition is smaller, encapsulated red phosphorus have certain humidification to fire proofing.Add
When dosage is smaller, red phosphorus masterbatch can be dispersed in fire proofing, and effective filling has been carried out to matrix material, improves
The consistency of material, and then the tensile strength of material is improve, and when addition further increases, encapsulated red phosphorus are in the base
It is difficult to be uniformly dispersed, under shearing stress effect, material surface is easy to produce crack, causes material damage.
Influence of the consumption of encapsulated red phosphorus to fire proofing bending modulus is as shown in Figure 4.
As shown in Figure 4, with the increase of encapsulated red phosphorus consumption, the bending modulus of fire proofing is dramatically increased, when its consumption
When increasing to 15% from 0, the bending modulus of fire proofing increases to 2472MPa from 1994MPa, and increasing degree is up to 23.97%.By
This is visible, and the addition of encapsulated red phosphorus contributes to the rigid increase of fire proofing.
(5) influence of the different toughener to fire proofing combustibility
Influence of the tri- kinds of consumptions of toughener of SBS, POE, EPDM to fire proofing combustibility is have studied respectively, specific knot
Fruit is as shown in table 3.
POE is ethylene octane copolymer, and EPDM is ethylene propylene diene rubber.
Influence of the toughener consumption of table 3 to fire proofing combustibility
As shown in Table 3, the addition of toughener does not influence the horizontal firing performance of flame-proof ABS, the water of different toughener samples
Flat burning grade is FH-1 grades.
During with SBS as toughener, the vertical combustion grade of fire proofing is not reduced with the increase of toughener consumption, all may be used
To reach FV-0 grades.Because the combustibility of SBS is more or less the same with the combustibility of ABS, and their compatibility is good,
Dispersed phase particles are good with the interface adhesion between base material, are uniformly dispersed.
During with POE as toughener, when its consumption is less than 9%, the vertical combustion grade of fire proofing can meet FV-0
The requirement of level, and after the consumption of POE meets or exceeds 9%, the vertical combustion grade of fire proofing is reduced to FV-1 grades.
During with EPDM as toughener, when its consumption is less than 15%, the vertical combustion grade of fire proofing can reach FV-
0 grade, and after the consumption of EPDM meets or exceeds 15%, the vertical combustion grade of fire proofing is reduced to FV-1.
Think after analysis, when POE or EPDM is toughener, the fire resistance of fire proofing can be reduced, and with SBS as toughness reinforcing
During agent, the fire resistance to fire proofing will not have a negative impact.
(6) influence of the different toughener to fire proofing mechanical property
The addition of inorganic combustion inhibitor can be such that the impact strength of ABS significantly declines, good comprehensive in order to make it have
Can must carry out toughening modifying.
First, inventor is blended with SBS, POE, EPDM and ABS respectively, investigates toughener consumption and fire proofing is rushed
The influence of hit intensity, as a result as shown in Figure 5.
From fig. 5, it can be seen that the impact strength of fire proofing increases with the increase of SBS consumptions, its consumption is less than 3%
When, than shallower, after its consumption is more than 3%, impact strength is dramatically increased with the increase of SBS consumptions for impact strength change, its use
After amount is more than 12%, the increasing degree of impact strength substantially slows down, and when its consumption is 12%, impact strength can reach
13.80kJ/m2, 7.88kJ/m is increased compared with the impact strength without toughening modifying fire proofing2, increasing degree is up to 133.11%.
And during with POE or EPDM as toughener, the impact strength of obtained flame-retardant material shows the trend of first increases and then decreases, it is most
Favourable opposition hit intensity is respectively 7.55kJ/m2And 8.90kJ/m2。
Dispersed phase particles are to reach one of excellent toughening effect necessary condition with interfacial adhesion good between base material.Cause
For, interphase can be formed in this kind of two-phase system, the feature of molecular motion is changed, the transmission and energy for being conducive to stress consume
Dissipate.
SBS is block copolymer, the S sections of two ends in macromolecular, and it forms a phase, butadiene with the S segments in ABS matrixes
Rubber segment part B forms a phase with the B segments in ABS matrixes.Therefore, SBS has good interface adhesion with ABS substrate,
It by firm earth anchor in the substrate.When sample is acted on by external force, SBS plays the role of to trigger and terminates crazing, and can be with
External influence is set transmission well to be obtained in system and is disperseed.When therefore, with SBS as toughener, can obtain with compared with
The composite of high impact.
In the composite of POE or EPDM toughness reinforcings, two touching positions almost without interphase exist, dispersed phase particles with
Interface adhesion between ABS substrate is poor.So relatively using SBS toughness reinforcings with the impact strength of POE or EPDM toughness reinforcing obtained flame-retardant materials
The impact strength of obtained flame-retardant material is poor.
Further, since the molecular structure of POE and EPDM is larger with the molecular structure difference of ABS, their compatibilities with ABS
Difference.So in the fire proofing of POE or EPDM toughness reinforcings, after toughener consumption exceeds 9%, toughener is in fire proofing
Dispersiveness will worse and worse, and toughener particle also will be increasing, and the toughener particle of oversized dimensions is to the performance of ABS
It is extremely harmful.Because under the conditions of φ d (volume fraction of dispersed phase) identical, big particle can make T (two adjacent rubber
Interparticle distance, also known as base material ligament thickness) value becomes big, and n (numbers of dispersed phase particles in unit volume) value diminishes, and then
Make the deteriorated impact toughness of material.On the other hand, because dispersed phase particles are different with the thermal coefficient of expansion of base material, macromolecule in addition
The poor thermal conductivity of material, when being cooled down from melt to room temperature, big toughener particle will bear larger stress and forced deformation,
Easily become stress raiser and material produces the nucleator of breach and destruction, cause material property to deteriorate.So, with POE or
When EPDM is toughener, the impact strength of obtained flame-retardant material shows the trend of first increases and then decreases.
Secondly, inventor is blended with SBS, POE, EPDM and flame-proof ABS respectively, investigates toughener consumption to fire-retardant material
Expect the influence of tensile strength, as a result as shown in Figure 6.
From fig. 6 it can be seen that with the increase of toughener consumption, the fire proofing tensile strength of three kinds of toughened systems is equal
Show downward trend.For the mechanical property in addition to impact strength, can illustrate that it changes with mixing principle.In toughness reinforcing
In the composite that agent/flame-proof ABS is constituted, by mixing principle, the mechanical property (except impact strength) of material is σ=σ pVp-
σ rVr, wherein σ for blend mechanical property, σ p, Vp for flame-proof ABS mechanical property and its content in the blend, σ r,
Vr is the mechanical property and content of toughener.With the increase of Vr, Vp is reduced, and σ is inevitably intended to σ r from σ p.And σ r are far low
Showed in the tensile strength of σ p, therefore fire proofing increases and downward trend with toughness reinforcing agent content.
Fig. 6 also shows, in three kinds of toughener, influences of the EPDM to fire proofing tensile strength is maximum, and POE is to fire proofing
The influence of tensile strength is slightly smaller, and influences of the SBS to fire proofing tensile strength is minimum.When toughener consumption increases to 15% from 0
When, the tensile strength of EPDM toughening flame-proof materials is reduced to 25.69MPa from 34.85MPa, and fall is 26.28%；POE toughness reinforcings
The tensile strength of fire proofing is reduced to 26.94MPa from 34.85MPa, and fall is 22.70%；SBS toughening flame-proof materials
Tensile strength is reduced to 30.83MPa from 34.85MPa, and fall is 11.54%.This is primarily due to SBS and ABS compatibilities
Good, dispersed phase particles are with there is good interface adhesion between base material.
Then, inventor is blended with SBS, POE, EPDM and ABS respectively, investigates toughener consumption curved to fire proofing
The influence of Qu Xingneng, as a result as shown in Figure 7.
It can be seen from figure 7 that three kinds of fire proofing bending moduluses of toughened system are with the increase of toughener consumption
Show downward trend.It is lower all than flame-proof ABS that this is primarily due to three kinds of bending moduluses of toughener itself.SBS and ABS
Structure is similar, and compatibility is good, and, with there is good interfacial adhesion between base material, compared with POE and EPDM, it is to resistance for dispersed phase particles
The bending property influence of combustible material is smaller.When toughener consumption increases to 15% from 0, the bending die of SBS toughening flame-proof materials
Amount is reduced to 2093Mpa from 2472Mpa, and fall is 15.33%；The bending modulus of POE toughening compositions drops from 2472Mpa
It is 1871Mpa, fall is 24.31%；The bending modulus of EPDM toughening compositions is reduced to 1720Mpa from 2472Mpa, under
Range of decrease degree is 30.42%.
When therefore, with SBS as toughener, ABS fire proofings have best impact strength, and SBS to the fire-retardant materials of ABS
Adverse effect produced by the tensile strength and bending modulus of material is minimum.
In sum, by the investigation to each component, inventor has drawn technical scheme of the present invention, uses nano-
It is fire-retardant that CG-ATH and encapsulated red phosphorus carry out synergistic to ABS, while carry out toughness reinforcing to fire proofing using SBS, has obtained having excellent
The low smoke halogen-free flame retardant ABS material of different mechanical property.Horizontal firing grade is FH-1 grades, and vertical combustion grade is FV-0 grades；Punching
Hit intensity 13-16kJ/m2, tensile strength 30-32MPa, bending modulus 2100-2200MPa.Fire proofing of the present invention is fire-retardant
The good, toughness of property is big, intensity is high, fire resistance and excellent in mechanical performance, is suitable to be used as various electricity such as computer, television set, mobile phone
The raw material of device housing.
