Description
Technical field
The utility model is related to rubber compound continuous mixing equipment technical field, more particularly to a kind of based on the preparation of strip initial rubber
Three phase materials rubber compound continuous mixing machines of elastomeric compound.
Background technology
Rubber industry is one of important foundation industry of national economy.It is indispensable that it not only provides daily life for people
The light industry rubber product such as daily, medical, and carried to the heavy industry such as digging, traffic, building, machinery, electronics and new industry
For various rubber system production equipments or rubber components.The product category of rubber industry is various, and backward industry is very wide.Sizing material is mixed
Refining is the first step in rubber production process, is also a most important step, in the prior art, can be by rubber grain
In be mixed into the material of different component, rubber overall performance is produced change, having carried out the rubber of batch mixing can more preferably be applied to not
Same occasion.Compounding rubber typically completes mixing using banbury, then the method for tabletting.Suitable for All Pure Nature rubber or mixed with conjunction
Into the sizing material of rubber, in one section of mixing action, frequently with the method that progressively feeds in batches, to make sizing material be unlikely to violent rise, one
As using banbury at a slow speed, it would however also be possible to employ double speed banbury, temperature when adding sulphur have to be lower than 100 DEG C.Its charging is suitable
Sequence is rubber-small powder-reinforcing agent-filler-oil-softener-discharge-cooling-plus sulphur and ultras.Industrial rubber
Mixed refining process almost all kneaded using banbury.
In view of above-mentioned technical problem, sizing material continuous mixing system (CCM) (patent No. of Pirell utility models：
US5711904 it) can be used for the continuous production of white carbon filler gum, solve the problem of Batch Process melting effect is uneven.
Pirell continuous mixing system is made up of two double screw extruders and a transition storage bin.The work of First extruder
Temperature range is 150 DEG C~200 DEG C, and course of reaction is completed in the extruder.Temporarily deposited after the sizing granulation kneaded
It is placed in transition storage bin.Crosslinking agent is added on second extruder, and its highest processing temperature is 120 DEG C.King enters literary grace use
Planetary Screw Extruder is kneaded to white carbon/rubber, as a result finds the method compared with batch process, the obtained sizing material of mixing
Performance after vulcanization, such as tensile strength and hardness are identical with batch process, and energy consumption reduction by 65%.Planetary Screw Extruder
Due to extremely strong cooling capacity, therefore all gum base ingredients, including crosslinking agent all can be metered in same feeding section,
It can realize that one-step melting is extruded.However, the sizing material continuous mixing system of Pirell utility models enters the planet of literary grace with king
Screw extruder raw materials are all granulated rubber and shot shape white carbon.Using granulated rubber raw material, not only increase
The preparation link of grain rubber, and due to the lighter weight of white carbon, the mixing of itself and rubber is difficult dispersed, is reduced mixed
The uniformity of refining, this seriously governs the performance quality of rubber, and the mixing problem of white carbon and rubber is so far without effective
Solution.
The A of CN 105034187 disclose a kind of rubber compound continuous mixing device, mainly measure feedway, glue by compounding ingredient
Piece metering and conveying device, machine barrel, driving screw, planetary-screw, brake hoop, mouth mold, transmission device, drive device, frame etc. are constituted,
Film metering and conveying device is located at machine barrel both sides, and to charge door metering conveying film, compounding ingredient measures feedway to charge door
Metering conveying compounding ingredient, two panels sizing material is clamped compounding ingredient and conveyed into machine barrel, and advances with the rotation of screw rod, the transverse direction through blade
Cutting so that the material ratio for entering planetary-screw gap is essentially identical, it is to avoid when granulated rubber is kneaded with white carbon, due to
Disperse uneven phenomenon caused by white carbon light weight, enhance melting effect.
The disclosure of above-mentioned patented technology, realize by Minifilm and powder, additive etc. mix it is full and uniform, improve and produce
Quality and the purpose for reducing energy consumption.Solving traditional rubber compound continuous mixing machine can not be directly to non-particulate initial rubber and other powder
The problem of material carries out continuous feed, using film for rubber as raw material, film of plasticating can be fed directly to the planetary extruder
Kneaded, reduce intermediate granulation link.But there is another in above-mentioned patent, i.e., again：Into the rubber compound continuous mixing
Material in device is, it is necessary in advance by catalyst such as film for rubber raw material and other powders and crosslinking agents in advance according to certain ratio
It is added in the hopper shown in Fig. 2, can not realizes lasting automatic into kneading machine in mixing process after example is well mixed
Charging, automatic batch mixing and the automatic accurate purpose for being proportionally well mixed all batch mixings.Due to mixer mixing plus
Work is a kind of batch-type mixer mode, and sizing material is transported in kneading machine, adopted again after needing to be well mixed after adding various small powders
It is to allow to batch mixing being well mixed with above-mentioned device, but the supply that the batch mixing entered in kneading machine can not continue, by
Certain temperature control is needed during mixing in kneading machine, be interrupted feed when it is impossible to ensure that kneading machine it is steady
Constant temperature degree, and temperature is the important parameter for determining mix quality, therefore also there is as mix quality is not between each batch
The problems such as homogeneous, high energy consumption, batch processed cause loss and the relative complex banbury accessory system of heat.Therefore it is required that feeding
The problem of virgin rubber material and carbon black and small powder entered can not realize continuous uninterrupted feed, seriously constrains the hair of continuous mixing equipment
Exhibition and industrialization promotion.
The content of the invention
The deficiency that defect for existing continuous mixing technology continuous feeding is present, technology to be solved in the utility model
Problem, which is to provide a kind of simple in construction, improvement non-particulate sizing material, powder, oil plant, can not realize continuous uninterrupted uniform mixing
