Description
Technical field
The present invention relates to a kind of method for improving carbon black dispersed homogeneous degree in masterbatch, belong to mixing technology field.
Background technology
In the prior art, rubber compounding charging sequence adds zinc oxide to be firstly added rubber after mixing certain time
Deng rubber master batch medicine, then add and oil plant is added after carbon black mixing certain time, continue mixing and reach temperature back glue, produce one
Section rubber master batch；One section of rubber master batch, which is entered back into after standing 8 hours in banbury, adds the refining medicine eventually such as sulphur, after mixing certain time, reaches
To temperature dumping, as finished composition.
The deficiency that the method is present is that carbon black mixing time in rubber is short, easily causes carbon black when amounts of carbon black is larger
Scattered inequality, influences sizing material quality；Larger when floating weight is depressed additionally, due to amounts of carbon black, part carbon black can be from floating weight and side
Emerged in gap between wall, easily cause environmental pollution.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art to improve carbon black there is provided one kind in masterbatch to disperse
The compounding process of the uniformity, so as to improve the carbon black dispension degree of elastomeric compound, improves sizing material quality, and reduces environmental pollution, has
Beneficial to workshop 5S field managements.
Technical scheme, improves the compounding process of carbon black dispersed homogeneous degree in masterbatch, walks by weight
It is rapid as follows：

（2）Carbon black and rubber feed intake：Take 60 ~ 90 parts of carbon black input steps（1）In the banbury, then proceed to add 100 parts
Rubber, depresses floating weight, carries out 40 ~ 50s of mixing using rotor rotation in kneading chamber, floating weight is floating to overturn sizing material；
（3）Dispensing is delivered：In step（2）Continue to put into rubber master batch medicine, specially 1 ~ 5 part of zinc oxide, tristearin in the kneading chamber
1 ~ 6 part of 0.5 ~ 4 part of acid and age resistor, pressure floating weight carry out 20 ~ 30s of mixing, lift floating weight, fill the sizing material of mixing chamber
Divide upset, that is, complete whole mixing process, obtain masterbatch.
Step（3）When dispensing is delivered, 1 ~ 6 part of resin is continuously added.
Continue toward step（3）Total mixing chamber delivers 2 ~ 15 parts of oil plant, depresses floating weight and carries out 25 ~ 35s of mixing,
Dumping is finally carried out, that is, obtains product masterbatch.
By collagen gauge, the carbon black mass exceedes the 60% of rubber quality.
The rubber includes the one or more in natural rubber, butadiene rubber, butadiene-styrene rubber and brominated butyl rubber.
The carbon black is specially one kind in N115, N234, N220, N134, N330, N326, N375, N660 and BL201
Or it is several.
The age resistor is specially two or three in antioxidant 4020, anti-aging agent RD and protection wax.
The resin is specially octyl group phenolic tackifying resins, tall oil modified reinforcing phenolic resin, tert-butyl group tackifying resin
With the one or more in anti-tear crack resin.
The oil plant is specially one kind in aromatic naphtha, naphthenic oil or environment-friendly aromatic oil.
Beneficial effects of the present invention：The inventive method is firstly added carbon black, adds rubber, makes sizing material in switching process
Carbon black will not be taken out dirt system and be taken away, it is ensured that sizing material quality；So that carbon black take part in whole mixing process, effective time is long,
Dispersion effect is good, is uniformly dispersed；Carbon black is in the lower part of kneading chamber, and rubber is on the top of kneading chamber, and such floating weight pressure is mixed
During refining, emerged between kneading chamber and floating weight there will be no carbon black, production scene 5S is also effectively improved.
