It is close that synchronous six rib sawtooth tangent type rotators are that the flow mechanism based on traditional six rib tangent type rotators improves
Mill rotor, by traditional tangent type mixer principle it is found that the quantity of tangent type rotator lug, nib, position, size, spiral angle,
The parameters such as top geometry and internal heat transmission capacity all have a significant impact to the quality for being kneaded product.Thus in tradition six
On rib rotor lug, nib plus the serrated slot of different gap, so that rotor is in the axial direction of cross section and the axial direction of rotor, rotor
Rib top and the gap of mixing locular wall are unequal, and due to the increase with the radius of gyration, the flowing velocity of sizing material also can phase
The increase answered.So holding the density to cut line groove can increase with the increase of the radius of gyration.
Compared with traditional tangent type rotator, six its existing similarity of rib sawtooth tangent type rotator, and have its unique excellent
Gesture.Due to cutting line groove at rotor lug, nib there are jagged, at the initial stage of mixing, sizing material be forced through lug, nib and internally mix locular wall or
When between two rotors, sizing material is not only by Strong shear, the stretching action between rotor and internally mix locular wall, also in rotor lug, nib keyway
Place has stronger shear tension to act on, and then generates more fresh surfaces, be conducive to various fillers, compounding agent distribution with point
It dissipates.
And with the reduction of shearing heating and Mooney viscosity, when viscoelastic sizing material is between lug, nib and internally mix locular wall, cut
The dilute sizing material of shear is easier to flow from keyway, to alleviate the strong shearing temperature rise effect of sizing material.And due to rotor lug, nib
Place be provided with it is jagged cut line groove, in mixing process, if two rotors have a velocity gradient, the gap at two rotor lug, nibs, place
In the state of dynamically changeable, intensive shear dispersion when small―gap suture not only may be implemented, but also the distribution cooling effect of wide arc gap can be packed
Fruit, so that the fully dispersed and Silanization reaction for white carbon black in the rotor of sawtooth pattern dynamically changeable gap provides effective guarantor
Barrier.
To examine it to influence the dispersed distribution of small powder, reality is compared using the rotor of zigzag rotor and non-tooth punching shape
It tests.
In embodiment and comparative experiments, traditional all-steel radial tire tread glue formula of use, formula is as shown in table 1 below.
1 tread glue formula of table
Using tread glue formula, using the Haake mixer of this laboratory development, respectively in two different rotor configurations
On be kneaded, analysis comparison is carried out to obtained experimental data.Respectively with regard to heating rate, carbon black dispension degree, mobility, physical machine
Tool performance etc. compares research, obtains influence of two different rotor configurations to properties of rubber.
In embodiment and comparative experiments, calendering process method specifically: revolving speed is set as 80r/min, constant temperature refining glue mode.
Charging sequence: adding virgin rubber to plasticate after 40s, mentions floating weight after adding the half of carbon black total amount and small powder (in addition to sulphur) to be kneaded 40s,
Remaining carbon black is added and white carbon black is kneaded into Haake mixer, then mentions a floating weight for 120 °, 130 ° mention a floating weight,
140 ° mention a floating weight.It is maintained at 140 ° -- one minute between 150 °, to 150 ° of dumpings.
The mixing of six rib sawtooth tangent type rotators and traditional tangent type rotator is carried out respectively using traditional tread glue formula
Experiment.Measure the dispersion degree, mooney viscosity, tensile strength, tearing strength, low strain dynamic shearing of the rotor glue stuff compounding of two kinds of configurations
Modulus etc..And the experimental data of two kinds of rotors is compared, obtains shadow of the rotor for properties of rubber of two kinds of various configurations
It rings.
(1) carbon black dispersion and sizing material analysis of Uniformity
With the dispersion angle value of carbon black dispension degree instrument test sizing material, compare two kinds of configuration rotor carbon black dispension degree situations, ties
Fruit is as shown in table 2 below:
2 carbon black dispension degree of table
Although the close clearance region of sawtooth pattern rotor is less than traditional tangent type rotator as shown in Table 2, since it is narrower
Narrow gap can provide effective shearing dispersion, and because sizing material is being forced through between fin and internally mix locular wall or two rotors
When, sizing material also has at rotor nog keyway stronger not only by Strong shear, the stretching action between rotor and internally mix locular wall
Shear tension effect, and then more fresh surfaces are generated, be conducive to the distribution and dispersion of various fillers, compounding agent, therefore six
The carbon black dispension degree of rib sawtooth tangent type rotator is better than traditional tangent type rotator.It can be seen that the form effect pair of high-shear region
Also there is good effect in the dispersion of carbon black.
(2) sizing material uniformity test
Using Alpha company RPA2000 rubber machining analyzer equally can dispersibility to white carbon black and uniformity into
Row analysis, in a piece of sizing material, chooses four position samples and carries out deformation scanning in RPA, if white carbon black dispersion everywhere
Degree is more concentrated, then the uniformity of sizing material is better.
Film 5min is adjusted under conditions of 60 °, and the scanning of deformation twice then is carried out for vulcanization style.As shown in figure 8,
Wherein modulus of shearing is " filler-filler " and " filler and rubber molecular chain " interaction in first time deformation scanning, and
Break the interaction between filler in scanning, and the modulus of shearing scanned for the second time is mainly shown as " filler and strand "
Interaction, can obtain the coefficient of dispersion by following formula:
Wherein payne (max) is the payne effect that the formula that silane coupling agent obtains is not added, i.e., under modulus of shearing curve
It is down to close to the area steadily covered with deformation abscissa.
Modulus of shearing curve is dropped to close to steadily horizontal with deformation when payne (1) position experimental program first time deformation scans
The area that coordinate is covered.
Modulus of shearing curve is dropped to close to steadily horizontal with deformation when second of the deformation of experimental program of payne (2) position scans
The area that coordinate is covered.
By Fig. 8 test result can be seen that the white carbon black good dispersions of six rib sawtooth pattern rotors in traditional tangent type rotator,
And six the uniformity of rib sawtooth pattern rotor glue stuff compounding be better than traditional tangent type rotator, sufficiently demonstrate six rib sawtooth pattern rotors
Be conducive to the theory of the fillers such as reinforcing agent mixing.White carbon black is easily assembled in mixing process, it disperses pole after aggregation
For difficulty, [3] could be scatter by needing repeatedly to shear.Account for portion really it is bright once discussed " the roomy good theory in gap ", refer to
" ' high-shear region is determined ' main problem that the degree of scatter of the compounding agent in rubber compound is proposed by Mckelvcy is to contain out
There is the sizing material of compounding agent to pass through the probability in this region and the product of it and rotor speed and mixing time." and pass through sawtooth
Slot, the gap between the rotor nog and mixing locular wall of increase, increases area of the sizing material by high-shear region, to enhance
The uniformity of the dispersion effect of white carbon black and same batch sizing material.
(3) analysis of heating rate
Fig. 9 is the temperature variation curve of mixing process.By the temperature variation curve of Fig. 9 mixing process it is found that being kneaded just
Phase, the heating rate of sawtooth pattern rotor almost maintain an equal level in traditional tangent type rotator, are because while the narrow of sawtooth pattern rotor
The area in gap is less than traditional tangent type rotator, but gap turns because being smaller than traditional shearing-type at sawtooth pattern rotor nog
Son, therefore the shear action being subject to is better than traditional tangent type rotator, and the initial stage sizing material of mixing is not only by rotor and internally mix
Strong shear, stretching action between locular wall, while the shearing heating at serrated slot is obvious, and as shearing heating and Mooney are viscous
The reduction of degree, when viscoelastic sizing material is between fin and internally mix locular wall, the sizing material of shear shinning is easier to flow from keyway, from
And alleviate the strong shearing temperature rise effect of sizing material.And sawtooth pattern rotor is because of narrower gap, between mixing locular wall
Frictioning effect becomes apparent from, and is advantageous to transmitting, the cooling of glue temperature.It can be seen that the temperature control effect of sawtooth pattern rotor is obvious
It is better than traditional shearing rotor.
(4) comparison of the rotor configuration to physical property
Sawtooth pattern rotor and the performance comparison of traditional tangent type rotator rubber compound are as shown in table 3.
The comparison of 3 physical property of table
As shown in Table 3, the Mooney viscosity of sawtooth pattern rotor rubber compound is lower than traditional tangent type rotator, after being conducive to sizing material
The processing of phase.By the portion's of accounting for really bright influence to closed-smelting machine rotor rib point from the gap of inner wall to mixing it is found that dispersion is different, turn
Son and mixing locular wall gap are just different to the effect of its glue stuff compounding, therefore there has been " close clearance is theoretical " and " ample clearance
Theory ", tetragonous sawtooth tangent type rotator be exactly designs carried out a little that both are theoretical in same rotor upper set and
Experimental study, experiment show: sawtooth pattern rotor is better than shearing rotor to the mechanical performance that sawtooth pattern rotor is kneaded on the whole.
(5) strain-dependent of different rotor configuration dynamic viscoelastic
Strain-dependent of the Payne effect of RPA commonly used to the dynamic viscoelastic of characterization filler reinforcement sizing material, Payne
The amplitude of variation of elastic shear modulus (G') when the size of effect can be quantified as low strain dynamic to Large strain, i.e. Δ G'.Δ G'=
G'0- G'∞, G'0Indicate the modulus under minimum strain, G'∞Indicate the modulus under maximum strain.Δ G' is bigger, Payne effect
It is higher, filler dispersibility it is poorer, i.e., the interaction between filler aggregation is bigger, and networking degree is higher, at the same filler with
The interaction of rubber is smaller.Influence of the sawtooth pattern rotor to modulus of shearing and Payne effect can be respectively from Figure 10, Tu11Zhong
It shows.
From in Figure 10,11 as can be seen that sizing material is under two kinds of configuration rotors, the G ' of vulcanizate with shear strain increase by
Gradually decline, this is because intermolecular sliding in sizing material, white carbon black network be destroyed and white carbon black and sizing material matrix it
Between sliding caused by.Since the shear action of tetragonous sawtooth pattern rotor is better than traditional tangent type rotator, white carbon black rate of dispersion
Faster than reunion speed, shear effect is obvious, and Silanization reaction efficiency is got higher, and Payne effect dies down, therefore the tetragonous sawtooth of low strain dynamic
The G' value and G'0-G'100% of type rotor are less than traditional tangent type rotator.
It can be obtained according to experimental data, six rib sawtooth tangent type rotators are integrally improved mixing compared to tradition shearing property rotor
Effect, temperature control effect are good.
1) sizing material Mooney viscosity value is lower compared with shearing rotor, the uniformity of the dispersion degree of carbon black and white carbon black, rubber compound
Traditional tangent type rotator is substantially better than in six rib sawtooth tangent type rotators.
2) heating rate is slow relative to shearing rotor when synchronous six rib sawtooth tangent type rotators are kneaded, and is more advantageous to white
The Silanization reaction of carbon black sizing material is suitable for temperature-sensitive material and high speed mixing process.
3) sawtooth pattern rotor is because flow effect good to the dispersion effect of filler, sizing material is good, the object of rubber compound
Rationality energy, wet-sliding resistant performance etc. are on the whole better than traditional tangent type rotator.Generally, by Experimental Comparison, six are synchronized
Influence of the mixing of rib sawtooth tangent type rotator to properties of rubber is integrally better than traditional tangent type rotator.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
