Description
Technical field
The present invention relates to refining glue technical fields, and in particular to a kind of refining glue side for improving the dispersion degree of rubber compound containing white carbon black
Method.
Background technique
At present in tyre production enterprise, all it is kneaded mostly using increase when being kneaded the formula glue kind for containing a large amount of white carbon blacks
Number reaches required dispersion effect using so-called high-dispersion white carbon black, increase white carbon black dispersing aid.And its is white
The dosage of carbon black is smaller, and control is in 10PHR or less mostly.As environmental consciousness is practicable in leading into exhibition a surname for people's livelihood industry,
All trades and professions all are being accelerated to rectify.And carbon black used in tyre industry is since there are pollution effect, white carbon blacks for its production technology
Production it is opposite clean, more and more tire enterprises are all in the usage amount for increasing white carbon black.And white carbon black is due to its molecule
Group reason, the compatibility between rubber is insufficient, although there is coupling agent to be made up, but still can not accomplish not having to high dispersive
White carbon black and required dispersion effect can be obtained by increasing significantly.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, provide a kind of refining glue side for improving the dispersion degree of rubber compound containing white carbon black
Method.White carbon black is put into together with raw rubber and part small powder mixer in advance and is effectively kneaded (mixing gimmick) by the present invention to be able to
It realizes.
In order to solve the above technical problems, the invention adopts the following technical scheme:
It is a kind of improve the dispersion degree of rubber compound containing white carbon black refining gluing method, the method the following steps are included:
Step 1: rubber group material, zinc oxide, stearic acid, activating agent, adhesive, white carbon black, carbon black N220 are put into simultaneously
Mixer；
Step 2: starting mixer shears the material of addition；
Step 3: softening agent is added after lifting floating weight when floating weight presses down；
Step 4: continuing mixing of pressurizeing；
Step 5: lifting floating weight carries out dumping, tabletting is cooling.
Further technical solution is the step two further include: carries out pressurization shear agitation to the material of investment.
Further technical solution was the time of the pressurization shear agitation not less than 55 seconds.
Further technical solution is to go back in the step three while anti-aging agent is added.
Further technical solution is the step three further include: while softening agent is added, on floating weight
Surface carries out purging movement.
Further technical solution is that mixing time is pressurizeed in the step four not less than 35 seconds.
Further technical solution is the step two further include: in operation process, controls mixer cooling cycle
Water temperature is at 30~40 DEG C.
Further technical solution is the step five further include: control dump temperature is not higher than 155 DEG C.
It includes: natural rubber, butadiene rubber and butadiene-styrene rubber that further technical solution, which is the rubber group material,.
Further technical solution is the rubber group material: 100PHR, white carbon black: 40-80PHR, carbon black: 0-
40PHR, activating agent: 5-8PHR, anti-aging agent: 1-3PHR, adhesive: 2-4PHR, softening agent: 6-10PHR.
Compared with prior art, the beneficial effect of the embodiment of the present invention first is that: the present invention implement after, can effectively accomplish
The operation of the common white carbon black of 30PHR or less reaches required dispersion effect, without additionally to increase white carbon black dispersing aid or
Increase and is kneaded number.
It is tested by practical operation, is measured point using the rubber compound of mixing method of the present invention by carbon black dispension degree tester
Scattered grade can stably reach 7 or more (detection device sets full marks as 10)；Using the conventional mixing side introduced in manual industry
The carbon black dispersion grade that method obtains is below 5, also just reaches 7 reluctantly after reasonable compounding conditions refine again.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract), unless specifically stated,
It is replaced by other equivalent or with similar purpose alternative features.That is, unless specifically stated, each feature is a series of
An example in equivalent or similar characteristics.
Below with reference to embodiment, specific embodiments of the present invention will be described in detail.
According to one embodiment of present invention, the present embodiment discloses a kind of refining glue for improving the dispersion degree of rubber compound containing white carbon black
Method, the rubber compound component and content of the refining gluing method include: natural rubber 40PHR, and common emulsion polymerized styrene butadiene rubber 30PHR is suitable
Buna 30PHR, white carbon black 70PHR, carbon black N220 10PHR, zinc oxide 2PHR, stearic acid 1PHR, activating agent (contain coupling agent)
5PHR, adhesive 3PHR, softening agent 9PHR.What PHR was indicated is additive percentage composition in rubber, (rubber content per hundred parts
parts per hundreds of rubber(or resin))。
Specifically, the refining gluing method of the present embodiment height dispersion degree of rubber compound containing white carbon black the following steps are included:
Step 1, it checks that floating weight of banbury mixer pushes bottom position, floating weight is promoted to a high position, by natural rubber, common cream
Poly- butadiene-styrene rubber, butadiene rubber, zinc oxide, stearic acid, coupling agent, adhesive, white carbon black, carbon black N220 put into close at 0 second
Mill,
Step 2, start the high speed shear of mixer, the shearing of high speed can allow three kinds of different rubber mutually to divide faster
It dissipates；Pressurization shear agitation 55 seconds, (being increased and decreased according to different white carbon black dosages) are carried out to the material of investment simultaneously.
Step 3, it (does not press down when floating weight just pressed down and just carries out next movement powder can be caused to be softened agent packet
It wraps up in, can not effectively infiltrate and poor dispersion；Carry out too late it is next movement will cause softening agent for the moment it is excessive, rubber compound and banburying chamber gold
It is too sliding to belong to wall contact surface, can not effectively shear), softening agent and anti-aging agent is added after lifting floating weight, while on floating weight
Surface carry out purging movement (powder for wafting and briming with out is blown off in banburying chamber, if do not purge can in dumping floating weight lift,
Corresponding powder, which can slide, causes rubber compound surface to cause poor dispersion with certain pulvis),
Step 4, repressurization is kneaded 35 seconds (its temperature is at 145 DEG C).
Step 5, lift floating weight and carry out dumping, the rubber compound proposed from banburying chamber carries out tabletting cooling by tablet press machine.
It takes rubber compound sample glue piece carbon black dispersion tester to detect, disperses grade 7.36.
The refining gluing method of the present embodiment is implemented, and can effectively accomplish that the operation of the common white carbon black of 30PHR or less reaches required
Dispersion effect is kneaded number without additionally to increase white carbon black dispersing aid or increase.
