Description
Technical field
The present invention relates to ultra-fine high dispersive rubber chemicals process units, belong to rubber chemicals technical field of processing equipment.
Background technology
Since reform and opening-up, China's rubber industry rapidly develops, and product type is gradually improved, and foreign trade constantly increases
Long, new material, new process, new technology are used widely, and modern rubber not only requires the inherent quality of rubber product, to rubber
The appearance requirement of product also has harsh requirement.
Rubber processing be generally divided into plasticate, compounding agent weighs, mixer mixing or mill mixing, open mill or
Person's extruder slice, back mixing, framework material assembly, semi-finished product molding, extrusion, calendering, injection, molding, vulcanization, product are repaiied
The processes such as decorations, packaging take several machining processes therein according to different rubber products and formula design requirement.With regard to wheel
For viviparous production. art, mono- 3 sections of generally use mixer l is kneaded the fast fast-growing with addition Sulfur and certain accelerating agents on open mill
Production. art, to the weighing technology of compounding agent, the quick of compounding agent is mixed into, rate of dispersion and uniformity propose very high requirement,
For the rubber product manufacturing technique requirent for meeting increasingly harsher, rubber chemicals (compounding agent) carry out at pre-dispersed or premixing
Reason, for improving rate of dispersion and uniformity, raising is mixed into speed, reduces weighing error and facilitates metering, reduces pollution, only
Change production environment, improves the tools such as production efficiency and have very important significance.
Traditional rubber chemicals are mostly powdery chemicals, although can be that rubber product and its processing bring great benefit,
But there is also many shortcomings：First, the compatibility of powdery auxiliary agent and rubber is poorer than pre-dispersed rubber chemicals master batch, relatively
Glue master batch product is more difficult to be evenly dispersed in rubber, therefore, can be less than in quality using the rubber product of powdery auxiliary agent and be adopted
With glue master batch product rubber product；Second is that more energy loss can be caused.When using powder rubber auxiliary agent, in order to be disperseed
Uniformly, the methods such as melting temperature are improved, this can bring more energy losses often using mixing time is extended in practical operation
And the problems such as being excessively crosslinked；Third, being not easy to automatically control dosage.Due to the physical characteristic of powdery auxiliary agent, rubber product is being added
During, it is easy to be suspended on vessel wall, is not easy to automatically control input；Fourth, shipping storage difficulty is than glue master batch class rubber
Auxiliary agent is big.
Powdery auxiliary agent is easy the moisture absorption, and memory requirement is higher than glue master batch shape auxiliary agent, and due to its powdered feature, transport at
This height.
Prior art representation be 103642133 A of Publication No. CN application for a patent for invention in, disclose it is a kind of not
Pre-dispersed glue master batch of dissolubility sulphur and preparation method thereof, it be formed using ethylene-propylene diene copolymer and butadiene-styrene rubber as colloid it is insoluble
Sulphur masterbatch composition, and EVA dispersants are added.Due to being usually with ethylene-propylene diene copolymer and butadiene-styrene rubber etc. in the prior art
Colloid causes the pre-dispersed insoluble sulfur glue master batch using the production of this technology poor to the compatibility of rubber, and sizing material adds
Work performance is poor, and production technology is complex, and production efficiency is relatively low, is easier to that caking agglomeration occurs and generates electrostatic to show
As, and it is relatively also easy to produce dust from flying, therefore have much room for improvement.
