Place has jagged cutting line groove, in mixing process, if two rotors have velocity gradient, then and the gap at two rotor lug, nibs, place
In the state of dynamically changeable, both can realize intensive shear dispersion during small-gap suture, the distribution cooling effect of wide arc gap can have been packed again
Really, thus effective guarantor is provided for the fully dispersed and Silanization reaction of white carbon in the rotor of sawtooth pattern dynamically changeable gap
Barrier.
For checking it that dispersed and distributed of small powder is affected, zigzag rotor and the rotor of non-tooth punching shape is used to carry out contrast real
Test.
In embodiment with contrast experiment, traditional all-steel radial tire tread glue formula of employing, formula is as shown in table 1 below.
Table 1 tread glue formula
Use tread glue formula, utilize the Haake banbury of this laboratory development, respectively at two kinds of different rotor configurations
On carry out mixing, obtained experimental data is analyzed contrast.Respectively with regard to heating rate, carbon black dispension degree, mobility, physical machine
Tool performance etc. carries out comparative study, obtains the impact on properties of rubber of two kinds of different rotor configurations.
Embodiment is with contrast experiment, and calendering process method is particularly as follows: speed setting is 80r/min, and constant temperature refines rubber moulding formula.
Charging sequence: add virgin rubber and plasticate after 40s, carries floating weight after adding the half of white carbon black total amount and small powder (except sulfur) mixing 40s,
Addition residue white carbon black and white carbon are to mixing in Haake banbury, and then 120 ° carry a floating weight, and 130 ° carry a floating weight,
140 ° carry a floating weight.It is maintained at 140 °--between 150 ° one minute, to 150 ° of binder removals.
Tradition tread glue formula is utilized to carry out the mixing of six rib sawtooth tangent type rotators and traditional tangent type rotator respectively
Experiment.Record the dispersion of rotor glue stuff compounding of two kinds of configurations, mooney viscosity, hot strength, tearing strength, low strain dynamic shearing
Modulus etc..And the experimental data of two kinds of rotors is compared, draws the rotor shadow for properties of rubber of two kinds of various configurations
Ring.
(1) carbon black dispersion and sizing material analysis of Uniformity
By the dispersion angle value of carbon black dispension degree instrument test sizing material, compare two kinds of configuration rotor carbon black dispension degree situations, its knot
The most as shown in table 2 below:
Table 2 carbon black dispension degree
Although the close clearance region of sawtooth pattern rotor is less than tradition tangent type rotator as shown in Table 2, but owing to it is narrower
Narrow gap area is provided that effective while of shearing scattered, when sizing material is being forced through fin and internally mix locular wall or two rotors
Between time, sizing material, not only by the Strong shear between rotor and internally mix locular wall, stretching action, also has relatively at rotor nog keyway
Strong shear tension effect, and then produce more unsalted surface, the most various fillers, the distribution of compounding ingredient and dispersion, because of
The carbon black dispension degree of this six ribs sawtooth tangent type rotator is better than tradition tangent type rotator.The shape effect of high-shear region as can be seen here
Tackle the dispersion in white carbon black and also there is important impact.
(2) sizing material uniformity test
The dispersibility of white carbon and uniformity can be entered by RPA2000 rubber machining analyzer equally that use Alpha company
Row is analyzed, and with in a piece of sizing material, chooses four position samples and carries out deformation scanning in RPA, if white carbon dispersion everywhere
Degree is more concentrated, then the uniformity of sizing material is the best.
Under conditions of 60 °, regulate film 5min, then twice deformation scanning is carried out for sulfuration style.As shown in Figure 8,
Wherein in the scanning of deformation for the first time, modulus of shearing is that " filler-filler " and " filler and rubber molecular chain " interacts, and
Scanning is broken the interaction between filler, and the modulus of shearing that second time scans mainly shows as " filler and strand "
Interact, the coefficient of dispersion can be drawn by below equation:
Wherein payne (max) is the payne effect being not added with the formula that silane coupler obtains, i.e. under modulus of shearing curve
It is down to the area covered close to steady and deformation abscissa.
During the scanning of deformation for the first time of payne (1) position experimental program, modulus of shearing curve drops to close to steady and deformation horizontal stroke
The area that coordinate is covered.
During the experimental program second time deformation scanning of payne (2) position, modulus of shearing curve drops to close to steady and deformation horizontal stroke
The area that coordinate is covered.
By Fig. 8 result of the test can be seen that the white carbon good dispersion of six rib sawtooth pattern rotors in tradition tangent type rotator,
And six the uniformity of rib sawtooth pattern rotor glue stuff compounding be better than tradition tangent type rotator, fully demonstrate six rib sawtooth pattern rotors
Be conducive to the theory of the filler mixing such as reinforcing agent.White carbon is easily assembled in mixing process, and after once assembling, its dispersion is by pole
For difficulty, need repeatedly to shear could be scatter [3].The portion that accounts for is the brightest once discussed " the roomy good theory in gap ", and it refers to
Go out that " ' high-shear region is determined ' subject matter that the degree of scatter of the compounding ingredient in elastomeric compound is proposed by Mckelvcy is to contain
There is the sizing material of a compounding ingredient probability by this region, and it and rotor speed and the product of mixing time." and pass through sawtooth
Groove, the gap between rotor nog and the banburying locular wall of increase, increase the sizing material area by high-shear region, thus strengthen
The dispersion effect of white carbon and the uniformity of same batch sizing material.
(3) analysis of heating rate
Fig. 9 is the temperature variation curve of mixing process.From the temperature variation curve of Fig. 9 mixing process, at the beginning of mixing
Phase, the heating rate of sawtooth pattern rotor is close to and maintains an equal level in tradition tangent type rotator, is because while the narrow and small of sawtooth pattern rotor
The area in gap is less than tradition tangent type rotator, but at sawtooth pattern rotor nog, gap is because smaller than tradition shearing-type turns
Son, the shear action therefore suffered from is better than tradition tangent type rotator, and mixing initial stage sizing material is not only by rotor and internally mix
Strong shear between locular wall, stretching action, the shearing at serrated slot simultaneously heats up substantially, and glues along with shearing the gentle Mooney of liter
The reduction of degree, when viscoelastic sizing material is between fin and internally mix locular wall, the sizing material of shear shinning is more easy to from keyway flowing, from
And alleviate the shearing temperature rise effect that sizing material is strong.And sawtooth pattern rotor is because of narrower and small gap, between banburying locular wall
Frictioning effect becomes apparent from, and is advantageous to the transmission of glue temperature, cooling.As can be seen here, the temperature control effect of sawtooth pattern rotor is wanted substantially
It is better than tradition shearing rotor.
(4) rotor configuration contrast to physical property
Sawtooth pattern rotor is as shown in table 3 with the performance comparison of tradition tangent type rotator elastomeric compound.
Table 3 physical property contrasts
Experiment shows: the mixing mechanical performance sawtooth pattern rotor on the whole of sawtooth pattern rotor is better than shearing rotor, and
And as shown in Table 3, the Mooney viscosity of sawtooth pattern rotor elastomeric compound is less than adding of the later stage of tradition tangent type rotator, beneficially sizing material
Work.From the brightest gap on closed-smelting machine rotor rib point and inwall, the portion of accounting on mixing impact, dispersion is different, and rotor is with close
Refining locular wall gap is the most different to its glue stuff compounding effect, therefore there has been " close clearance is theoretical " and " ample clearance theory ",
Four rib sawtooth tangent type rotators both is theoretical at same rotor upper set just the design and the experiment that carry out a little are ground
Study carefully.
(5) strain-dependent of different rotor configuration dynamic viscoelastic
The Payne effect of RPA is commonly used to characterize the strain-dependent of the dynamic viscoelastic of filler reinforcement sizing material, Payne
The big I of effect is quantified as the low strain dynamic amplitude of variation to the elastic shear modulus (G') during Large strain, i.e. Δ G'.Δ G'=
G'0-G'∞, G'0Represent the modulus under minimum strain, G'∞Represent the modulus under maximum strain.Δ G' is the biggest, Payne effect
The highest, the dispersibility of filler is the poorest, i.e. interaction between filler aggregation is the biggest, and networking degree is the highest, simultaneously filler with
The interaction of rubber is the least.Sawtooth pattern rotor can be respectively from Figure 10, Tu11Zhong on the impact of modulus of shearing and Payne effect
Show.
It can be seen that sizing material is under two kinds of configuration rotors from Figure 10-11, the G ' of vulcanizate with shear strain increase by
Gradually decline, this is because sliding between sizing material Middle molecule, white carbon network are destroyed and white carbon and sizing material matrix it
Between sliding cause.Owing to the shear action of four rib sawtooth pattern rotors is better than tradition tangent type rotator, white carbon rate of dispersion
Faster than reunion speed, shear effect is obvious, and Silanization reaction efficiency uprises, and Payne effect dies down, therefore low strain dynamic four rib sawtooth
The G' value of type rotor and G'0-G'100% are less than tradition tangent type rotator.
Can obtain according to experimental data, six rib sawtooth tangent type rotators are integrally improved mixing compared to the tradition property sheared rotor
Effect, temperature control effect are good.
1) sizing material Mooney viscosity value is relatively low compared with shearing rotor, white carbon black and the dispersion of white carbon, the uniformity of elastomeric compound
Tradition tangent type rotator it is substantially better than in six rib sawtooth tangent type rotators.
2) when six rib sawtooth tangent type rotators are mixing, heating rate wants slow relative to shearing rotor, is more beneficial for white carbon
The Silanization reaction of sizing material, is suitable for temperature-sensitive material and high speed mixing process.
3) sawtooth pattern rotor is because good to the dispersion effect flow effect good, sizing material of filler, the therefore thing of its elastomeric compound
Rationality energy, wet-sliding resistant performance etc. are better than tradition tangent type rotator on the whole.Generally, by Experimental Comparison, six rib saws
The mixing entirety that affects on properties of rubber of tooth tangent type rotator is better than tradition tangent type rotator.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
